1 - PS/2 ConnectorsATX boards have 2 PS/2 connectors, one for the mouse and one for the keyboard. They
are the same size the same shape but a different colour. This is because the Mouse and
keyboard connectors are not interchangeable. Plugging the keyboard in to the mouseconnector and vice versa will make them both useless. The usual way for these to be
plugged in is the mouse into the Green connector and the keyboard into the purple
connector.
2 - USB (Universal Serial Bus) PortsUSB is getting more and more popular for external components. So much so that you can
even buy external USB hard disks now. The big hype about USB as that you can change
the devices on the USB without switching the power off the computer. If you have a
mouse and a Scanner plugged into USB for example, and you wanted to play your new
game on your USB controller, you could unplug your Scanner and plug in your gamecontroller. The system would then recognise the change and let you use the controller
straight away. You will normally get 2 USB ports with an option to add an extra 2 via a
cable.
3 - Parallel PortThe parallel port is mainly used for scanners and printers, and is associated with LPT1.
Parallel ports send data in parallel i.e. more than one bit at a time. If the channel is 8bits
wide then a parallel port would send 8 bits at a time. Parallel ports are fast becoming
extinct as the USB port takes over the purpose of this port.
4 - Game Port

The Game port is really just a serial port normally found on a sound card. as the picture
above has onboard sound in order to show you everything an ATX motherboard can have
on it, the game port is above the sound connectors. Gamepads and joysticks plug into the
game port. The game port is a female connector and larger than that of the standard COM
port.
5 - Sound card ConnectorsThe Sound card that is built into the board has three connectors, these are Speaker out,
this is your main output for your computer speakers, depending on your sound chip you
may or may not need powered speakers. Check with the motherboard manual for this.
Then you will have the Line in, Line in is for external sources of audio that you want to
hear through your computer or possibly record, i.e. from your Hi-Fi. The last of the 3 is
the Mic in port. This is for the Microphone. The Microphone can again be used to add
sound to recording or just to play through your speakers as a karaoke system.
6 - Display ConnectorThis motherboard also has onboard graphics, if this is the case with your motherboard
then you will have this connector on your motherboard. The Display connector (VGA
Connector) is also female (meaning the pins will be on the end of the monitor cable.) If
you have a VGA graphics card then this connector will be on the back of your graphics
card.
7 - COM (communications) PortThe COM port is used for peripherals such as mice and modems, becoming less popular
now though as USB and PS/2 have taken over. Motherboards seem to only have the 1 or
no COM ports now in favor of more USB ports.

General system requirements and recommendations
This topic specifies the minimum hardware configurations required by Discovery Studio andthe operating systems on which Discovery Studio is supported. In general, the better the
hardware configuration of your computer, the better your experience with Discovery Studio
will be.
To achieve a more satisfying experience with Discovery Studio, particularly in terms of the
client software, it is highly recommended that your system be substantially better than the
minimum requirements specified in the following sections. This is particularly true if running
server software locally on the same system as the client software.
Attention to the following areas can make a significant improvement to your overall user
experience and enjoyment of the software:

Memory - the more RAM your computer has, the better.
CPU speed - the faster, the better.
A high quality OpenGL graphics card can make a significant difference to the graphics
performance.
The higher the display resolution, the more flexibility you have in displaying and
managing document and dialog windows. Mouse - although not absolutely necessary, a three-button mouse or a two-button mouse
with a wheel is strongly recommended. Such a mouse facilitates the manipulation of many
of the views used in Discovery Studio.
For example, a PC with 512 MB RAM, a CPU speed of 2 GHz and a workstation-class
OpenGL graphics card should give good performance. PC hardware capabilities are currently
advancing so rapidly that a new commodity desktop PC would have significantly higher
specifications than these.

Five reasons why people uninstall an application1: It hasnt been used for a while, and maybe is not really useful
2: Their computer is slowing down and they need to free up some memory
3: It takes too long time to run
4: It doesnt work well/its buggy
5: Its difficult to understand how to use it
There are many methods of uninstalling a program from computer. Following the right procedure
will lessen if not totally eliminate the chances of having errors caused by wrong uninstall process.
Effective methods of uninstalling programs are listed here.
Step 1: Uninstall using the Windows Add/Remove program.The Add/remove Feature of the Windows operating system can uninstall most of programs
installed in the system. Here's an example on how to uninstall Google Toolbar from any Windows
computer.
o Open the Start menu and select the Control Panel
o In the Control Panel window, double-click Add or Remove optiono Look for Google Toolbar in the Currently Installed Program list
o Click the Change/Remove button and follow the instructions
o You may need to restart your PC to complete the uninstall process
Step 2: Uninstall Using the Program UninstallerSome programs that you install on your computer don't show up in the Add or Remove Programs
list. There is another way to effectively remove it from the computer. Most programs have
Uninstall application file in its folder. A shortcut of that application is listed in the Start menu.
o Open Start menu and point to All Programs
o In the All Programs menu point to the program you want to uninstall

o Select the Uninstall option to start the uninstall process
o Follow the instructions to complete the process
If the uninstall program option is not available, perform a search for the folder where the program
files are stored. Most programs are stored in the My Program folder found in My Computer.
Double click the uninstall file for the program in this folder to start the uninstall process.
Step 3: Using Third-Party UninstallersThere are programs that add so many entries in the registry and copy so many files in the
different folders that it is almost impossible to uninstall them without leaving traces behind. An
effective way of getting rid of those leftover is by using Third-Party uninstaller. Many third Party
uninstallers can be found in the internet. Look for the third party uninstallers that also clean the
registry.
Step 4: Removing Programs with No UninstallersThere are programs that do not have any uninstallers available. These programs can be
uninstalled manually by deleting it from the program folder and editing the registry. You can alsoremove these programs by upgrading to a later version
Local printers
The most common way to install a printer is to connect it directly to your computer. This is
known as a local printer.
If your printer is a universal serial bus (USB) model, Windows should automatically detect it
and begin installation when you plug it in.
If you're installing a wireless printer that connects to your computer over a wireless network
(Wi-Fi), you can use the Add a device wizard to install the printer. For instructions,
If it's an older model that connects using the serial or parallel port, you might have to install it
manually.

Preventive Maintenance ProceduresIf they are carried out on a regular basis, these regularly scheduled Windows PC procedures
will keep a system from getting so "out-of-tune" that a system crash is imminent, and will
also prevent other problems before they occur. Regular maintenance in Windows system
covers basics such as cleaning up, backing-up data, removing obsolete programs, Microsoft
updates, other security updates and defragmentation.
Cleaning Up
7/30/2019 Managing Computer.pdf
11/13
Every computer builds up temporary material. Files are generated and the system registry willadd more entries. A computer user needs to regularly clean the file system and registry.
Back-Up Data
If the hard drive fails, any data may be lost completely. So it should be backed up regularly to
an eternal storage resource like CD, DVD or external hard drive.
Remove Obsolete Programs
A computer owner may have installed many programs. It is good practice to uninstall
obsolete programs, since they not only take up valuable space, but they will also use system
resources.
Microsoft Updates
Microsoft updates must be applied since they will enhance the system and also prevent
problems occurring later on, and these also help protect against harmful threats applied within
documents.
Virus and Malware Checker Updates
It is important to keep anti-virus and anti-malware programs updated. Many of these database
updates are automatic. The owner is unprotected until the program is updated, and this iswhen the user is vulnerable to threats.
Defragmentation
Windows PCs require regular defragmentation. This should be done weekly and particularly
if there is a client email program like Microsoft Outlook because it will write to the driveoften.

(installing all of them might take up too much space on your drive).
6. Click OK, and then click Install updates. If you're prompted for an administrator
password or confirmation, type the password or provide confirmation. You might have
to restart your computer too.
How do I get additional display languages?
You can add display languages by installing additional language files. When you install language files,
you can view wizards, dialog boxes, menus, Help topics, and other items in Windows in a differentlanguage.
There are two types of language files:
Windows 7 language packs. Windows 7 language packs provide a translated version of most of
the user interface.
Note
Language packs are available in Windows 7 Ultimate through Windows Update as optional
updates. They aren't installed automatically. If you're using Windows 7 Enterprise, contact your
system administrator for information about installing additional languages.
To get additional language packs by using Windows Update
Windows 7 Language Interface Pack (LIP). Windows 7 LIPs provide a translated version of the
most widely used areas of the user interface. LIPs are freely available to download. Because not
all of the user interface is translated, LIPs require at least one parent language. The parts of the
user interface that aren't translated into the LIP language are displayed in the parent language.
When you download the LIP, you get the parent language requirements for that language. The
parent language pack needs to be installed before the LIP can be installed. For more information,
including a list of available languages, go toDownload languages
for Windowson Windows online.

items in your preferred language.
In Windows 7, you can download languages in two ways:
Using Windows Update. If you're running an Ultimate or Enterprise edition of Windows, you
can download available language packs by using Windows Update. Language packs installed
using Windows Update provide a fully translated version of Windows dialog boxes, menu items,
and help content. All the languages available for this type of download have a "Learn how" link
in the right column of the table below.
Using the links on this page. You can download Language Interface Packs (LIPs) from
the Microsoft Download Center by using the links below. You can install LIPs over any edition of
Windows, but they provide a translated version of only the most widely used dialog boxes, menu
items, and help content. To install a LIP, you will need to have the required parent languageinstalled on your PC.
The table below shows if the language you're looking for requires a premium edition of Windows or a
particular parent language.
