DH2W 35 Computer Networking: Building a Network PC - Assessment Exemplar
1 Introduction
This pack must be used in conjunction with a copy of the Unit specification which
details the standard of performance expected of the candidate. A copy of the Unit
specification can be obtained from SQA.
This pack supplements the assessment guidelines and support notes of the unitspecification. It aims to provide an example of assessment that is valid, reliable and
practicable. The assessment task(s) detailed in this pack correspond to the assessment
guidelines outlined in the Unit specification.
The example provided is intended for guidance only. It may be used in a variety of
ways including, for example:
♦ To exemplify the standard of performance expected of candidates achieving the
Unit, i.e. as a benchmark
♦ To help you develop your own assessment for the Unit
♦ To help you develop valid and practicable assessments for other Units within the
subject area of the group award to which it contributes
♦ To give you new ideas
♦ As a staff development tool.
It is important that you make sure that the Assessment Exemplar is used in a context
appropriate to the delivery of the Unit and to the group award of which it forms a part.
It is also very important that you note that using this Assessment Exemplar does not
automatically guarantee successful external moderation. It is still your responsibility
to make sure that all the appropriate internal quality assurance procedures are
satisfactorily completed. For example, a valid, effective and approved internalmoderation system must be in use at your centre.

2 How to generate evidence
Introduction
The Scottish Qualifications Authority’s system of assessment measures the evidence of a
candidate’s attainment of knowledge, understanding and skills against defined criteria. Theassessment process must allow for evidence of each candidate’s performance to be generated
and collected. This evidence must then be judged against the standards set out in the Unit
specification. To achieve the Unit the candidate must successfully meet the standards and
there must be evidence to prove this.
The Unit specification defines the criteria you need to use to judge whether or not the
candidate has met the standards. All units have the following:
Outcomes
These tell you what the candidate actually has to do.
Knowledge and/or skills
This section details the essential knowledge and skills which the candidate must attain in
order to achieve each Outcome, combination of Outcomes or for the Unit as a whole.
Evidence requirements
Evidence requirements can be written for each Outcome, for a combination of Outcomes, or
for the Unit as a whole. There is no standard format for writing evidence requirements.
Provided that they state clearly and unambiguously the type, standard and amount of evidence
which candidates have to produce in order to be judged competent, the evidence requirements
can be written in the format which will be most easily understood by users of the Unit.
NOTE: The national standard of achievement expected, which was previously specified as performance criteria, is now stated in the evidence requirements.
Where it is not possible to cover all the items listed under knowledge and/or skills
through holistic assessment, sampling can be used as a method of gaining additional
evidence. Sampling may also sometimes be an appropriate method of assessing very
knowledge-based units. This type of assessment must always be carried out in
supervised conditions.
Where sampling is used, the evidence requirements must clearly state:
♦ The standard of evidence required for each knowledge and/or skills item so that
satisfactory performance can be judged whichever items are sampled on any one
occasion
♦ The proportion of knowledge and/or skills which can be sampled
♦ Whether any item(s) must be included in each assessment, ie if it is crucial to the
achievement of the Outcome(s) or to an embedded core skill
♦ The fact that a different sample should be chosen on each assessment occasion to
prevent candidates being able to foresee what they will be asked
♦ The conditions of assessment

DH2W 35 Computer Networking: Building a Network PC - Assessment Exemplar
Assessment Guidelines
This section should give guidance on how best to conduct the assessment to generate the
evidence required, eg recommending the use of a particular assessment instrument. It should
include guidance on how to integrate the assessment of the whole Outcome or, if appropriate,
how to link assessment holistically with other outcomes in the Unit. Like evidence
requirements, assessment guidelines can be written for each Outcome, a combination of
Outcomes, or for the Unit as a whole.
It is important to realise that it is up to the assessor to judge when and if the candidate has
satisfactorily met the standards. This decision should be based on the quality and correct
quantity of evidence collected, set against the standards in the Unit.
The assessment instrument in this pack should not create any unnecessary barriers to
achievement for open/distance learning delivery or candidates with special needs. However,
you may need to adapt it so that you can assess candidates with special needs or candidates
who are undertaking the Unit on an open/distance learning basis. Obviously, whilst taking
into account the needs of the candidate concerned, the methods of assessment you choosemust still be valid, reliable and practicable. If you have any questions or problems, or if you
are in any doubt as to whether or not the alternative assessment you have chosen is still valid,
please contact the Helpdesk at the Scottish Qualifications Authority on tel: 0141 242 2214.

DH2W 35 Computer Networking: Building a Network PC - Assessment Exemplar
Answers with Explanations
Q1: Answers b and e are correct. Most modern systems boards include PCI and AGP
slots. The MCA bus developed by IBM never caught on because it was not
backwards compatible with ISA. VL-buses were predominantly used prior to the
adoption of PCI and AGP and suffered from timing problems. EISA busses although
backwards compatible with ISA became primarily a network file server niche market.
ISA busses are occasionally still seen on fairly recent motherboards but have largely
been replaced by PCI slots on the most modern motherboards.
Q2: Answers c is correct. Socket 7 is a type of socket designed to take a flat, pin grid
array (PGA) CPU. They are much less common than they used to be but are
occasionally still seen. PGA CPU, including, Socket 7 uses ZIF or Zero Insertion
Force as a mechanism for inserting and removing the CPU package without the use of
force and for locking the CPU into place. It has nothing to do with SIMMs. Slot 1 is
an INTEL-designed architecture for mounting a CPU on a printed circuit board,
which is then plugged by means of an edge connector into a slot on the motherboardand has nothing to do with increasing or decreasing the CPU clock speed.
Q3: Answers b is correct. Cache is an intermediate area of high-speed SRAM that is
positioned between the CPU and the RAM. When the CPU requests a piece of data
from RAM, the request is intercepted by the cache controller, which searches the
cache first. Only if the data is not in cache is a request made to the RAM. A
combination of optimising algorithms, and judicial sizing of the cache means that
very high hit-rates for the cache are achievable.
The L1 cache is integrated on the CPU die. As processor speeds increased additional
high-speed memory was required ands this became known as L2 cache. Typically,
though not invariably L2 cache was not located on the
CPU die. The new 64-bit processors from INTEL and AMD use a further level of
caching known as L3 cache. CMOS is used to store configuration settings for the PC.
Duplex memory and a processor-resident pipelines do not exist.
Q4: Answers A and D are correct. The North Bridge sits between the Processor bus
and the PCI bus and handles the medium-fast devices including SDRAM and AGP
slot. The USB ports and the IDE drives are attached to the South Bridge and the
COM ports are attached to the Super I/O chip.
Q5: Answer A is correct. This is a classic symptom of the ribbon cable beingconnected the wrong way around. Floppy disk drives do not require additional
drivers. You cannot connect the floppy ribbon cable to the IDE connector as they are
different sizes. This is not a symptom of the CMOS being incorrectly configured.
Q6: Answer C is correct. IPQ 9 is used for vectoring to IRQ 2. IRQ 15 is the
Secondary hard disk controller. IRQ 3 is required by COM 2 and COM 4.
Q7: Answers A and C are correct. A significant technical enhancement for the 800
series of chipsets was the adoption of Intel's new Accelerated Hub Architecture,
which removed the PCI bus as the main component-interconnect. This allowed areas
such as the IDE channel to have a direct connection to the chipset without having to pass through the PCI bus.

http://slidepdf.com/reader/full/building-a-pc-sqa-exemplar 19/63
DH2W 35 Computer Networking: Building a Network PC - Assessment Exemplar
The integration of the I/O controller also meant that the North Bridge/South Bridge
controller division could be dispensed with, which is key to Intel’s plans to end
support for the legacy ISA architecture.
Q8: Answer D is correct. The controller for a hard drive is on the circuit board
attached to the drive. Thus something is deeded to arbitrate between the drives whenthey are using the same IDE channel. Setting the jumpers on the drives so that one
drive is a master drive, and the other drive is a slave drive does this. Logical Unit
numbers (LUNs) are associated with SCSI devices. The BIOS can only correctly
auto-detect the drives if the jumpers have already been correctly set.
Q9: Answer A and C are correct. The ATX introduced greatly improved power
management, including a new fool proof keyed 20-pin Molex connector, and a 3.3v
supply in addition to the +/-5V and +/-12V connections, which obviated the need for
an on-board voltage regulator
Another feature of the ATX design was the integration of the I/O Port Connectors andPS/2 Mouse connector directly on to the motherboard in the form of a double-height,
external I/O connector panel. This meant ribbon cables were no longer required to
connect pin-headers on the motherboard to the ports on the back of the case. The
reduction the number of ribbon cables and general clutter greatly improved air flow
around the case and hence cooling. Although some ATX form-factor motherboards
support RAMBUS many do not. In general low-profile cases are used with LPX or
NLX motherboards that support riser cards, which allow expansion cards to be
inserted horizontally rather than vertically, thus reducing the height of the case. A
key factor in the disappearance of the ISA slot was that the ISA bus is too slow for
modern devices and the introduction by Intel of the AHA architecture chip set.
Q10: Answer A is correct. The bus needs to be terminated at either end. This is true
whether the HBA is at one end of the bus as in this case or in the middle of the bus in
which case it is the device at either end that is terminated and not the HBA.
Q11: The correct answer is B. The PSU takes in an AC power supply and converts it
to ± 12v DC, 5.5v DC and 3.3v DC. Quality PSUs have limited capabilities to
smooth out spikes but that is not their primary function
Q12: The correct answer is C. The motherboard will not short out. AT motherboards
shorted out if the power connectors were connected the wrong way around. Constant
bleeping at POST almost invariably means a memory problem.
Q13: The correct answer is C. A standard VGA monitor has a resolution of 640
pixels horizontally and 480 pixels vertically.
Q14: The correct answer is B. Residual toner is removed to the waste receptacle
during the cleaning phase. The toner is attracted to the paper from drum using the
secondary coroner during the transfer phase. All residual charge is removed from the
drum during the conditioning phase. The image is permanently fixed to the paper
during the fusing stage

There are four classifications of fire and an extinguisher A, B, C and D
Class A extinguishers are used to deal with fires involving materials such as paper,wood, cardboard, and most plastics.
Class B extinguishers are for fires involving flammable or combustible liquids such as
petrol, kerosene, grease and oil.
Class C means the extinguishing agent does not conduct electricity, which is why
class C extinguishers are used on electrical fires. Water should never be used on a
electrical because of the risk of electric shock.
Class D extinguishers are used on fires involving involve combustible metals, such as
magnesium, titanium, potassium and sodium and are therefore commonly found in
chemical laboratoriesSome extinguishers have a multi-purpose rating such as ABC, the exception are class
D extinguishers which may be used only on class D fires.
Only class B, C or D extinguishers can be used to fight a fire involving a computer or
a computer monitor.
Question 2
Carbon Dioxide is a non-inflammable gas. Carbon dioxide extinguishers do not work
by displacing the oxygen feeding a fire in order to extinguish it. This may not work
very well on class A fires because they may not be able to displace enough oxygen to
put the fire out properly so that it subsequently re-ignites.
Question 3
The purpose of PAT is too regularly test portable electrical equipment such as
computer base units, printers, and monitors are safe to use. The legislation does not
define how often "regular" is. Good practice presumes regular testing is done once a
year and no less than three years apart.
Question 4
The IEE Code of Practice states that states that the tester must be,
"Competent to undertake the inspection, and where appropriate, testing of
electrical equipment and appliances with due regard to their own safety
and others."
A number of organisations undertake to train PAT testers to meet the IEE Code
of Practice, and the City and Guilds 2377 Code of Practice.
Question 5
The purpose of a fuse is to protect the mains-cable, not as commonly supposed the
device itself. Sometimes, when an electrical device develops a fault a surge may
occur in the cable. The purpose of the fuse is to blow and break the circuit when thesurge becomes large enough to compromise the integrity of the mains-cable.

DH2W 35 Computer Networking: Building a Network PC - Assessment Exemplar
To calculate a fuse rating two pieces of information are required the mains-voltage,
240 volts in the UK, and the power consumption of the device in watts. The
maximum wattage is then divided by the mains-voltage.
Question 6
An RCD is a safety device designed to immediately switch of the electricity when
electricity "leaking to earth" is detected at level harmful to the person using electrical
equipment.
It works by continuously monitoring the current flow in both the Active (supply) and
Neutral (return) conductors of an electrical circuit. An RCD operates if too much of
the current in the active conductor is not returning through the neutral conductor. An
RCD will disconnect within 10 - 50 milliseconds of detecting the harmful leakage,
which would typically be about 30 milliamps.
Question 7
LSZH cables, sometimes referred to as LS0H cables are designed to emit no toxic
fumes and little or no smoke when exposed to flame. In addition, LSZH cable does
not emit corrosive acids when burned. By contrast PVC cable contain chlorine, which
emits toxic fumes when burned. If these cables are sprayed with water when burning
corrosive acids will be formed.
Question 8
Given the characteristics of LSZH cabling it is used anywhere where toxic fumes and
smoke from burning cable could endanger life, for example, in tunnels, enclosed-
rooms, aircraft and minimum ventilation areas. In many countries local building
codes require LSZH cabling in the plenum space as well, which is typically between astructural ceiling and a suspended ceiling or under a raised floor.
Question 9
An ESD wrist strap is an elasticated wristband that has a metal pad worn next to the
skin. It also contains a large resistor in order to protect the wearer from an electric
shock. A cable from the strap runs to a ground connector, which may fit into a plug
that connects to earth in the mains or to a specially fitted earth circuit.
When working inside a computer the wrist strap should be earthed by connecting it to
an electrical outlet or to an anti-static mat that is connected to a mains outlet.
Question 10
There are three circumstances in which the use of an ESD wristband can be lethal:
when working on a computer chassis that is connected to the mains-supply, when
working on a monitor, and when working on a laser printer.
The PSU in a PC converts the 240 v mains-supply down to 12 v or less. The
capacitors that are used in this process store a large quantity of electricity, which, if
discharged, through a human being could be fatal.
A monitor converts the mains-voltage from 240 volts to 2000 volts to charge the
cathode ray tube. A shock from this would almost certainly be fatal.Finally, a laser printer also uses a charge of over 2000 volts to attract the toner. This is

DH2W 35 Computer Networking: Building a Network PC - Assessment Exemplar
a static charge, and concentrating it to the ESD wrist strap uses the wearer as the earth
and this is, therefore, potentially dangerous.
Unless working on a computer that is disconnected from the mains, any repair activity
using an ESD strap is too dangerous.
Question 11
Static electricity can build up in environments where humidity is very low. The
problem is most likely to occur during the winter months when it is cold and the
humidity is low or in extremely dry climates where the humidity is low all year
around.
Question 12
Flexible leads, particularly those connected to portable equipment that is moved a
great deal, can become frayed and the plugs and sockets are also vulnerable to
damage. Extension leads, an all too common feature around PCs and in workshops,
are similarly liable to damage
Question 13
Ensure that people working with electrical equipment have been properly trained and
are competent to do the job and have a thorough knowledge of the hazards of working
with electrical equipment
Suspect or faulty equipment is taken out of use, labelled 'DO NOT USE' and kept
secure until examined by a competent engineer
Whenever possible, equipment and mains-supply sockets must be switched off before
equipment is plugged or unplugged.
Switch off and unplug equipment before cleaning it servicing it
Question 14
If the live wire becomes loose and touches the chassis of the PC, it becomes live. If
you then touch the metal, the currents will flow through you and give you an electric
shock. The earth wire prevents this by completing the circuit as soon as the live wire
touches the metal. A large current flows to earth and blows the fuse.
Question 15
You should never open a PSU or a monitor unless specially trained to do so. They
both contain very large capacitors capable of storing a potentially lethal charge long
after being switched off. In fact a PSU should never be repaired. They are relatively
inexpensive and should be replaced with a new one.

3. Findings
3.1. Motherboards
A survey of motherboards indicates that there are 4 basic types, AT, ATX, LPX and
NLX. AT and ATX motherboards are found in standard desktop and tower cases
where as LPX and NLX are found in slim line cases. ATX and NLX motherboards
were designed to address a number of issues associated with the AT and LPX
motherboards. For example, power was supplied to the older motherboards via two
nearly identical six-pin plugs, which could easily be connected the wrong way around.
This had the effect of destroying the motherboard when it was powered up. In
addition, connectors such as the serial ports and LPT ports were mounted on blanking
plates at the rear of the motherboard and connected via ribbon cables to pin-headers
on the motherboard. This tended to obstruct the flow of air around an AT system
leading to problems associated with overheating. The expansion slots were located in
front of the processor. Before heat sinks and fans became necessary long expansion
cards could extend over the CPU. With the advent of heat sinks and fans the
processor assembly prevented the use of long expansion cards in up to three of the
expansion slots. The location of memory in the form of DIMM and SIMM modules
was also inconvenient.
The ATX form-factor motherboard addressed these issues by moving the expansion
slots so that they were beside the CPU socket. In addition, the serial ports and LTP
port were built onto the motherboard obviating the need for some of the ribbon cables
inside the case, and hence improving the flow of air around the case.
A foolproof 20-pin, keyed, Molex power supply-connector and a built-in voltage
regulator and soft power to the motherboard were also useful improvements
introduced by the ATX and NLX form-factors.

http://slidepdf.com/reader/full/building-a-pc-sqa-exemplar 34/63
DH2W 35 Computer Networking: Building a Network PC - Assessment Exemplar
3.2. CPUs
There are two principal manufacturers of CPUs AMD and Intel. Processor sockets
may be slotted or Pin-Grid-Arrays. Processors were originally in PGA format but in
an effort to speed up the transfer of data from the Level 2 cache, to the L1 cache andthe processor processors were mounted on small expansion cards that plugged
into a slot on the motherboard. As technology improved, particularly with the
introduction of high-speed front-side busses, modern processors are built using the
PGA form factor.
AMD and Intel slotted processors looked very similar, however the electrical and
signalling characteristics of the slots were very different and Intel and AMD devices
were not interchangeable. Modern PGA processors have differing numbers of pins.
For example socket 370 has 370-pins. Intel uses Socket 423 and 478 for its Pentium 4
chips and Socket 603 for its Xeon chips. AMD use sSocket 462 for its Athlon and
Duron chips and Socket 754 for it new 64-bit processor.
PGA is a generic term and there are several identifiable versions of the PGA form
factor including FC-PGA Flip Chip-Plastic Grid Array (FC-PGA), which is
physically but not electrically compatible with Socket 370. However the physical
changes put the core closer to the surface, allowing better cooling as the processor
core comes in closer contact to the heatsink. Another variant is the SPGA or
Staggered Pin Grid Array, which is so-called because in which the pins are staggered
on the underside of the chip rather than in standard rows and columns.
Particular CPUs will often only work with particular motherboard chipsets.
3.3. PSUs
A survey of PSUs indicates that there are 4 basic types, AT, ATX, LPX and NLX.
ATX and NLX are more modern that AT and LPX power supplies and support a
number of features common to ATX and NLX motherboards. These include a 20-pin
Molex power connector and soft power to the motherboard.
The PSU is an important component. A poorly built PSU will cause the system to
perform erratically and may even catch fire. The power supply should have a
sufficiently high power rating to support all of the components in the system. A good
starting point for a modern system is a rating of at least 300 Watts.

3.4. Software Compatibility
3.4.1 PSU
Reference to the Microsoft HCL indicates no significant compatibility problems with
power supplies
3.4.2 Motherboards
Reference to the Microsoft HCL indicates that there are a number of excellent ATX
standard motherboards that are full Windows XP compliant. For example the ABIT
IS-10, which is a micro ATX form factor main board based on the 865G chipset,
supporting the Intel Pentium 4 CPU and the ABIT VA-10 described by Microsoft as
“the ultimate multimedia and cost effective platform for AMD CPUs”
Offerings from ACHATES include the SY-7VBA133U (VIA 694T ATA100) a
66/100/133MHz FSB socket 370-based ATX motherboard and the SY-P4IS2 (845
AGPset) P4 Socket 478-based ATX motherboard.
Other major vendors offering Windows XP compatible motherboards include
ASRock, ASUSTek, BIOSTAR and CHAINTECH
3.4.3 CPUs
There are a number of excellent CPUs that are fully Windows XP Compliant.
Compatible processors include the Duron, Athlon, Opteron, Sempron and Athlon MP
from AMD and from Intel the Celeron, Xeon and P4.

4. Conclusions
Only high-quality PSUs with an adequate power rating for installed devices should be
used and it should match the form factor of the motherboard and case
CPUs need to be matched to the chip set and socket or slot type of the motherboard.
If used with Microsoft Operating Systems, the Microsoft Hardware Compatibility List
should be consulted to ensure that the hardware is compatible with the operating
system of choice.

5. Recommendations
Before purchasing a motherboard, CPU and PSU make sure that they are of good
quality and that the form factor of the motherboard is compatible with the form factor
of the case and of the power supply.
Make sure that the processor is electrically and physically compatible with the
processor socket and slot
Make sure that all of the hardware is compatible with the operating system of choice.

3. Findings
3.1. Types of System
There are two types of system available to the charity: proprietary systems
manufactured by companies such as Compaq and DELL and IBM PC clone systems.
The advantage of purchasing a proprietary system is that it can be delivered tailored
by the manufacturer to meet the specification laid down by the charity, with the
operating system and application software pre-loaded and with a variety of warranties
ranging on-site fix to return-to-base. The major disadvantage with proprietary system
is that they frequently have non-standard components, notably the motherboard and
therefore have a very limited upgrade path.
The advantage of an IBM clone is that it is built around a standard form-factor
motherboard, for example ATX and, as a result, has a better upgrade path. Although
most PC clone hardware has a return-to-base warranty, on site fix is often not an
option. Furthermore, the purchaser is usually required to install and configure any
software.
The proprietary system-option is often slightly more expensive to purchase but by the
time the software has been purchased for the clone there is often little overall
difference in price of the two types of system.
Processing Power
3.2.1 The Operating System
The charity wishes to use Microsoft Windows XP professional, together with
Microsoft Office and the SAGE Instant Accounts accounting package. As a
minimum Microsoft recommend that Windows XP requires: a minimum of a Pentium
Class processor or equivalent running at 233 MHz, 64MB of RAM, a 2GB hard disk
partition with 640MB of free space. They also recommend a minimum of a 12 x CD-
41
8/2/2019 Building a PC - Sqa Exemplar
http://slidepdf.com/reader/full/building-a-pc-sqa-exemplar 42/63
DH2W 35 Computer Networking: Building a Network PC - Assessment Exemplar
Reader a VGA class video adapter a keyboard and pointing device such as a mouse or
roller-ball. A more realistic specification might be a 1.5 - 2GHz processor, 512MB of
RAM, with the disk size determined not only by the requirements of the operating
system, but including the disc space required by the applications and the amount of
user data the charity expects to store on each PC. In addition a VGA adapter does not
offer much in the way of either resolution or number of colours and a SVGA adapter
would be more appropriate. Since an increasing amount of software is being
distributed on DVD a DVD reader/writer might be a better choice than a CD-Reader.
3.2.1 The Microsoft Office 2000/XP Suite
The specification noted above is also perfectly adequate for running the Microsoft
Office Suite.
3.2.2 The SAGE Instant Account package for Small Businesses
The minimum specification for the accounting package is a 400MHz Pentium Class-
processor 128MB or RAM and 150MB of disk space for the application files. There
is also a requirement for an SVGA adapter card capable of supporting 256 colours at
800 x 600 pixels. Although SAGE will run with a 400MHz processor and 128MB of
RAM and 150MB of disk space, SAGE recommend that this be increased to a 2GHz
processor, 512MB of RAM, 500MB of disk space and an SVGA monitor capable of supporting 24-bit True-Colour at 1024x768 pixels.
In addition, a copy of Internet Explorer v 6 must be installed on the computer.
Hardware Compatibility
The hardware selected must be, for trouble-free operation totally compatible with the
software. The suitability of the hardware for Windows XP can checked against the
Windows XP Professional hardware Compatibility List on the Microsoft Web site.
Although some proprietary systems are billed a "Windows XP compatible", and when
they are delivered Windows XP will be up and running, the drivers for certain
hardware components are not in the XP drivers CAB file. This means that should it
ever become necessary to re-install Windows XP, the drivers for these devices must
be obtained from the hardware vendor's Web site. A typical example is the Intel
PRO/100 VR Fast Ethernet NIC found in some IBM Thinkpad Systems.
SAGE specifically state on the Web-site that a Pentium class processor is preferred.

http://slidepdf.com/reader/full/building-a-pc-sqa-exemplar 43/63
DH2W 35 Computer Networking: Building a Network PC - Assessment Exemplar
4. Conclusions
The advantages of a proprietary system are that they can be delivered "ready to go"
and frequently come with an on-site fix warranty. The disadvantages are that they
may be slightly more expensive and have a poor upgrade capability. In addition some
of the components while they are "XP-compatible" the drivers for some of the
hardware devices may not be in the XP driver CAB file.
The advantages of a clone are that they are built around standard components such as
an ATX motherboard and will almost certainly have a better upgrade path. They are
likely to be cheaper than a proprietary system. The disadvantages are that the
purchaser is often required to install and configure the software and the warranty will
probably not be as good.
Given the recommended hardware requirements for the accounting package a Pentium
class processor of 2.5 - 3GHz would not only meet current requirements but would
have some future proofing to meet potential additional processing power required by
upgrades to the operating system and the application software. Although the
Operating system, Office Suite and the accounting package will fit into 3GB of disk
space, this makes no allowance for user data. Given the relative cheapness of modern
hard disks, a disk of 100GB should be considered. In addition a high quality video
adapter supporting 24-bit True Colour at 1024x768 pixels and a DVD reader/writer
would be appropriate.
Any purchase of hardware should be checked to ensure full compatibility with the
operating system and the application software by consulting the software vendor's
Web sites.

http://slidepdf.com/reader/full/building-a-pc-sqa-exemplar 44/63
DH2W 35 Computer Networking: Building a Network PC - Assessment Exemplar
5. Recommendations
The charity should purchase hardware to meet the following specification:
2.5 - 3GHz Pentium class processor
512MB RAM
100GB Hard disk drive
1.44MB Floppy disk drive
SVGA video adapter capable of supporting 24-bit True colour at 1024 x 768
100Mb/s Fast Ethernet Network Interface card
DVD reader/writer
Minimum of 4 USB ports
Keyboard and pointing device
Given the nature of a small charity and the likely lack of in-house expertise, a
proprietary system might be appropriate if sufficiently future-proofed when
purchased.
All hardware to be checked for compatibility with the operating system and
application software.
In addition a good virus checker such as Norton or AVG should be installed and kept
up-to-date in case a virus is introduced to the network on the inevitable floppy disk
"brought in from home".

Record the details of any work carried out including testing
I put the case on a properly grounded workbench and removed the cover by
removing the four screws on the back of the PC and pulling the case backwards
and upwards. Next I connected my anti-static wrist strap to a bare-metal part of the PC
chassis.
I screwed the brass spacers into the base plate of the case to correspond with the
mounting holes in the motherboard. At one end of the motherboard there was a
hole that did not correspond to a hole in the base plate. In here I put a plastic
stub-spacer to prevent the possibility of the motherboard coming into contact
with the case by accident. I then put the motherboard into the case and screwed
it firmly into place.
I aligned the processor up with the PGA-ZIFF socket aligning the corners of the
processor that did not have pins with the corners of the socket where there wereno pin holes a dropped it into position. I closed the ZIFF socket by pushing the
lever at the side of the socket down and locking it into place. I put a measured
amount of thermal conduction paste on the underside of the heat sink and fan
and placed this on top of the processor and locked it into place using the lugs on
the ZIFF socket provided for this purpose. I made sure that the power supply
for the fan was in the CPU FAN pin-header. It is important to use this pin-
header for this purpose because when the machine powers up the BIOS will
look for a load on this circuit. If it doesn’t find it, it will assume the fan is not
connected and shut the PC down after a few seconds.
Next I installed the memory. This was a DIMM module, which I inserted into
the socket as shown below.
Next I set the jumpers on the hard drive to CSEL (cable select) and mounted in
the drive bay in the case using the four screws provided with the drive. I then
installed the floppy drive in its drive bay and the CD-Reader/Writer into its
drive bay after ensuring it was configured as a master drive. Then connected
the EIDE cable to the hard drive. Since the hard drive and the motherboard
support ULTRA-ATA I used an 80 conductor cable making sure the blue end of
the cable was plugged into the blue IDE pin-head connector (IDE 1) on the

motherboard and the opposite end, the black end into the drive, making sure that
the red-stripe on the cable was correctly aligned with pin 1. See below for
typical jumper settings.
As the CD-ROM device was a standard device I used a standard IDE cable to
connect it to IDE 2. Finally I connected the FDD to the motherboard using an
FDD cable. I then connected the power connectors to the drive units.
I then connected the 20-pin molex connector from the power supply to the
motherboard and as the motherboard was an ATX motherboard I connected the
soft-power connector to the motherboard.
Finally, I connected the connectors the LEDs and reset-button.
After showing what I had done to the instructor I closed the case. The instructor
then tested the PC using MICROSCOPE 2000 PC diagnostic software.
Outline the nature of any problems encountered & their solution
There were no problems. There were no soundcards or video cards to install as these
together with a LAN adapter and 4 USB ports were built into the motherboard. This
particular motherboard used an Accelerator Hub chip-set rather than the North
Bridge/South Bridge chipset so it did not have any ISA sockets only a limited number
(three) PCI shots in addition to an additional AGP socket.

1. Terms of Reference
A small charity was given a donation of money to purchase a small number of
computer systems to create a small peer-to-peer network. On the 18th May 2005, Mr
XXXX XXXX, Treasurer of the charity commissioned a report into the most
appropriate type of Networking Protocol for use of The Charity's peer-to-peer
network.

3. Network Protocols
A protocol is a set of rules. A computer networking protocol is a set of rules for
communicating across computer networks.
This report will consider two computer networking protocol NetBEUI and TCP/IP
3.1. TCP/IP Transmission Control Protocol / Internet Protocol (TCP/IP) is the de facto standard
for Internetworking. Unlike the ISO OSI model it has four layers, but they map more
or less onto the eight-layer OSI model as shown In Figure 1.
Figure 1 also shows that TCP/IP is a much larger suite of protocols than the name
suggests there are in fact fourteen separate protocols shown in the Figure and there are
more. TCP operates in Transport layer of the model while IP operates at the
Internetworking layer .
IP is a routed protocol , which means that IP packets are transmitted across network
paths discovered by routing protocols such as the Routing Information Protocol
(RIP) or Open Shortest path First (OSPF), which are included in the diagram under
the generic heading of "Routing protocols".
TCP is a connection oriented protocol that supports error correction and guaranteed
delivery, the other transport protocol in the Host-to-Host layer User Datagram
Protocol (UDP) is connectionless and does not support error correction. As a result,
UDP is faster but less reliable. UDP can be used where the error correction
capabilities of TCP are not required, for example if the application using the services
of TCP/IP has its own error correction capability.Other protocols in the suite include Domain name Service (DNS), used to convert

first is when using the multiple IP method. In this case, all of the network cards
should have TCP/IP for Internet connectivity and NetBEUI for file and printer
sharing.
The other occasion is if the LAN has the protection of a separate network and a
firewall or proxy but it becomes necessary to open ports in the firewall or add TCP or
UDP mapping services to a proxy server. Under these circumstances, there will be
direct connections to the LAN for at least some data from the Internet. For example
opening ports TCP or UDP ports 137, 138, and 139 will allow access to a LAN's
computers from the Internet when using TCP/IP for File and Printer sharing. Under
these circumstances, NetBUEI can be a good option for File and Printer sharing.
3.2. The Key Differences
The key differences between TCP/IP and NetBEUI are:
IP is routable and NetBEUI is not
TCP/IP is a suite of networking protocols whereas NetBEUI is really an
extended API.
NetBEUI is less complex than TCP/IP in an environment that may be short in
computer networking expertise.

4. Conclusions
Given that the charity's LAN is not connected to the Internet and is a single segment
peer-to-peer network NetBEUI would represent a simple and relatively non-technical
solution to their networking needs.

Task and Planning Title: To configure a peer-to-peer PC
Outline of task to be undertaken
To install a Realtek RTL 8139B PCI Fast Ethernet Network Interface Card
(NIC) into a PC
Connect the PC to a Fast Ethernet switch that is part of the peer-to-peer
network
To configure TCP/IP onto the network 192.168.1.0/24
Test the installation by testing the loop-back address and pinging another PC
on the network
Outline the procedure you plan to adopt
Switch of the PC and disconnect it from the mains
Open the case and on a correctly grounded workbench
Connect the anti-static wrist strap to the PC chassis
Remove the NIC from its antistatic bag
Insert the NIC into a vacant PCI slot and screw it into place.
Disconnect the anti-static strap
Close the case Attach the NIC to the hub
Reconnect the PC to the mains and restart
Configure the TCP/IP properties of the NIC
Test it
Record the details of any work carried out including testing
Having disconnected the PC from the mains I put the PC on a properly
grounded work bench and removed the casing by removing the four screws on
the back of the PC and pulling the case backwards and upwards. Next I connected my anti-static wrist strap to a bare-metal part of the PC

chassis.
I opened the anti-static bag containing the NIC and laid it on the bag on the
bench within easy reach.
I unscrewed and removed one of the blanking plates adjacent to a vacant PCI
slot. This I replaced with the NIC, which I gently but firmly pressed into the
slot to ensure that it was correctly seated. I then screwed it into place I disconnected my wrist strap and replaced the case.
I used a straight-through CAT 5 drop-lead with RJ-45 connectors at either end
to connect the NIC in the PC to the switch and powered up the PC.
The computer was running Windows XP Professional so after logging in as the
Administrator I clicked Start | Setting | Network Connections and selected
Properties from the drop-down menu. This brought up the Local Area
Connection Properties dialogue box as shown.
I highlighted Internet Protocol TCP/IP and clicked the Properties button to bring
up the Internet Protocol (TCP/IP) Properties dialogue box.
As the peer-to-peer network was not connected to any other subnets, and did not
have DHCP or DNS Servers I had to configure a static IP address and a subnet
mask but not a default gateway or a Preferred DNS Server as shown

To test the installation, when I first connected the NIC to the hub and powered
up the machine I checked the NIC to make sure that both the ACT and LINK
lights were lit. Next I ran ipconfig at the command prompt to make sure I had configured the
IP address correctly. See below
Next I performed a loop back test by attempting to ping the IP address 127.0.0.1
as shown below.
Finally I attempted to ping another PC with IP address 192.168.1.201 as shown
below.
Outline the nature of any problems encountered & their solution
This exercise was simple and straightforward. Once the NIC was installed in the PC,
