Q1. What is data and information?

Data can be defined as a representation of facts, concepts or instructions in a formalized

manner which should be suitable for communication, interpretation, or processing by human

or electronic machine.Data is represented with the help of characters like alphabets (A-Z,a-

z), digits (0-9) or special characters(+,-,/,*,<,>,= etc.).

Information is organised or classified data which has some meaningful values for the

receiver. Information is the processed data on which decisions and actions are based.

Q2. What is Computer?

A computer is a general purpose device that can be programmed to carry out a set of

arithmetic or logical operations automatically. Since a sequence of operations can be readily

changed, the computer can solve more than one kind of problem.

Q3. Define Computer Network.

A computer network or data network is a telecommunications network that

allows computers to exchange data. In computer networks, networked computing devices

pass data to each other along data connections. Data is transferred in the form of packets.

The connections (network links) between nodes are established using either cable

media or wireless media. The best-known computer network is the Internet.

Q4. Define Internet and Intranet.

Internet- A means of connecting a computer to any other computer anywhere in the

world via dedicated routers and servers. When two computers are connected over the

Internet, they can send and receive all kinds of information such as text, graphics,

voice, video, and computer programs.

Intranet-It is Internal or private network of an organization based

on internet technology (such as hypertext and TCP/IP protocols) and accessed over the

internet. An intranet is meant for the exclusive use of the organization and

its associates (customers, employees, members, suppliers, etc.) and is protected

from unauthorized access with security systems such as firewalls.

Q5. Operating System

An operating system (OS) is software that manages computer hardware and software

resources and provides common services for computer programs. The operating system is an

essential component of the system software in a computer system. Application programs

usually require an operating system to function.

Q6. Define Booting

When we start our Computer then there is an operation which is performed automatically by

the Computer which is also called as Booting. In the Booting, System will check all the

hardware’s and Software’s those are installed or Attached with the System and this will also

load all the Files those are needed for running a system.

Q7. Define memory.

Memory is the electronic holding place for instructions and data that your computer's

microprocessor can reach quickly. When your computer is in normal operation, its memory

usually contains the main parts of the operating system and some or all of the application

programs and related data that are being used.

Q8. Define Input and output devices.

Input devices- A component or peripheral device (such as a barcode reader, graphic tablet,

keyboard, magnetic-stripe reader, modem, mouse, scanner, or stylus) that feeds data or

instruction into a computer for display, processing, storage, or outputting or transmission.

Output devices- A display device is an output device that visually conveys text, graphics, and

video information. Information shown on a display device is called soft copy because the

information exists electronically and is displayed for a temporary period of time. Display

devices include CRT monitors, LCD monitors and displays, gas plasma monitors, and

televisions.

Page 3: New Microsoft Office Word Document.docx

Q9. Define Process

In computing, a process is an instance of a computer program that is being executed. It

contains the program code and its current activity. A computer program is a passive

collection of instructions; a process is the actual execution of those instructions.

Q10. Functions performed on file and folders.

The various functions that can be performed on file and folders are as follows;

Cut

Copy

Delete

Rename

Share

Q11. DBMS

A database management system (DBMS) is a collection of programs that enables you to

store, modify, and extract information from a database. There are many different types of

DBMSs, ranging from small systems that run on personal computers to huge systems that run

on mainframes. The following are examples of database applications:

computerized library systems

automated teller machines

flight reservation systems

computerized parts inventory systems

Q.12 Define Software.

Software is a general term for the various kinds of programs used to operate computers and

related devices. (The term hardware describes the physical aspects of computers and related

devices.) Software can be thought of as the variable part of a computer and hardware the

invariable part. Software is often divided into application software (programs that do work

Page 4: New Microsoft Office Word Document.docx

users are directly interested in) and system software (which includes operating systems and

any program that supports application software).

Q.13 Define computer language

A language is defined as the medium of expression of thoughts. All the human beings in this

world communicate with each other by a language. Similarly, computer also needs some

expression medium to communicate with others

A computer follows the instructions given by the programmer to perform a specific job.

1) FIRST GENERATION LANGUAGES 1GLs (Machine language)

2) SECOND GENERATION LANGAUAGES 2GLs (Assembly Language)

3) THIRD GENERATION LANGUAGES (3GLs ) (High Level Languages)

4) FOURTH GENERATION LANGUAGES (4GLs)

Q. 14 Difference between Compiler and interpreter.

A compiler is a piece of code that translates the high level language into machine language.

When a user writes a code in a high level language such as Java and wants it to execute, a

specific compiler which is designed for Java is used before it will be executed. The compiler

scans the entire program first and then translates it into machine code which will be executed

by the computer processor and the corresponding tasks will be performed.

Interpreter

Interpreters are not much different than compilers. They also convert the high level language

into machine readable binary equivalents. Each time when an interpreter gets a high level

language code to be executed, it converts the code into an intermediate code before

converting it into the machine code. Each part of the code is interpreted and then execute

separately in a sequence and an error is found in a part of the code it will stop the

interpretation of the code without translating the next set of the codes.  

Q.15 Generation of computer

First Generation (1940-1956) Vacuum Tubes

Second Generation (1956-1963) Transistors

Third Generation (1964-1971) Integrated Circuits

Fourth Generation (1971-Present) Microprocessors

Page 5: New Microsoft Office Word Document.docx

Fifth Generation (Present and Beyond) Artificial Intelligence

Q.16 what are the various types of computer?

Since the advent of the first computer different types and sizes of computers are offering

different services. Computers can be as big as occupying a large building and as small as a

laptop or a microcontroller in mobile & embedded systems.The four basic types of computers

are.

1. Super computer

2. Mainframe Computer

3. Minicomputer

4. Microcomputer

Q.17 Define Protocols.

In information technology, a protocol is the special set of rules that end points in a

telecommunication connection use when they communicate. Protocols specify interactions

between the communicating entities. 

Protocols exist at several levels in a telecommunication connection. For example, there are

protocols for the data interchange at the hardware device level and protocols for data

interchange at the application program level.

Q.18 What are the various devices in computer networking?

List of Computer Networking devices.

Gateway: device sitting at a network node for interfacing with another network that uses

different protocols. Works on OSI layers 4 to 7.

Router: a specialized network device that determines the next network point to which to

forward a data packet toward its destination. Unlike a gateway, it cannot interface different

protocols. Works on OSI layer 3.

Bridge: a device that connects multiple network segments along the data link layer. Works on

OSI layer 2.

Page 6: New Microsoft Office Word Document.docx

Switch: a device that allocates traffic from one network segment to certain lines (intended

destination(s)) which connect the segment to another network segment. So unlike a hub a

switch splits the network traffic and sends it to different destinations rather than to all

systems on the network. Works on OSI

layer 2.

Hub: connects multiple Ethernet segments together making them act as a single segment.

When using a hub, every attached device shares the same broadcast domain and the same

collision domain. Therefore, only one computer connected to the hub is able to transmit at a

time. Depending on the network topology, the hub provides a basic level 1 OSI model

connection among the network objects (workstations, servers, etc). It provides bandwidth

which is shared among all the objects, compared to switches, which provide a dedicated

connection between individual nodes. Works on OSI layer 1.

Repeater: device to amplify or regenerate digital signals received while setting them from one

part of a network into another. Works on OSI layer 1.

Some hybrid network devices

Multilayer Switch: a switch which, in addition to switching on OSI layer 2, provides

functionality at higher protocol layers.

Protocol Converter: a hardware device that converts between two different types of

transmissions, such as asynchronous and synchronous transmissions.

Page 7: New Microsoft Office Word Document.docx

Brouter: Combine router and bridge functionality and are therefore working on OSI layers 2

and 3.

Digital media receiver: Connects a computer network to a home theatre.

Hardware or software components that typically sit on the connection point of different

networks, e.g. between an internal network and an external network.

Proxy: computer network service which allows clients to make indirect network connections

to other network services.

Firewall: a piece of hardware or software put on the network to prevent some

communications forbidden by the network policy. Other hardware for establishing networks

or dial-up connections.

Multiplexer: device that combines several electrical signals into a single signal.

Network Card: a piece of computer hardware to allow the attached computer to communicate

by network.

Modem: device that modulates an analog "carrier" signal (such as sound), to encode digital

information, and that also demodulates such a carrier signal to decode the transmitted

information, as a computer communicating with another computer over the telephone

network.

ISDN terminal adapter (TA): a specialized gateway for ISDN.

Line Driver: a device to increase transmission distance by amplifying the signal. Base-band

networks only.

Q.19.Define MS Word

Microsoft Word is a word processor developed by Microsoft. It was first released in 1983

under the name Multi-Tool Word forXenix systems. Commercial versions of Word are

licensed as a standalone product or as a component of Microsoft Office,Windows RT or the

discontinued Microsoft Works suite. Freeware editions of Word are Microsoft Word

Viewer and Office Online, both of which have limited features.

Q.20 Define Window.

An enclosed, rectangular area on a display screen. Most moder noperating

systems and applications have graphical user interfaces(GUIs) that let you divide your

display into several windows. Within each window, you can run a different program or

display differentdata.

Windows are particularly valuable in multitasking environments , which allow you

to execute several programs at once. By dividing your display into windows, you can see

the output from all the programs at the same time. To enter input into a program, you

simply click on the desired window to make it the foreground process .

Q.22What is a network topology

In communication networks, a topology is a usually schematic description of the arrangement

of a network, including its nodes and connecting lines. There are two ways of defining

network geometry: the physical topology and the logical (or signal) topology.

Q.23 Virus

A computer virus is a malware program that, when executed, replicates by inserting copies of

itself (possibly modified) into other computer programs, data files, or the boot sector of

the hard drive; when this replication succeeds, the affected areas are then said to be

"infected".

hardware and the system BIOS. 

7) it sets particular values corresponding to the windows environment. 

8) used to run particular programs during startup. 

9) file management- it helps in creation, saving and deletion of files 

10)environment management

Page 10: New Microsoft Office Word Document.docx

Random Access Memory (RAM) is the best known form of Computer Memory. The

Read and write (R/W) memory of a computer is called RAM. The User can

write information to it and read information from it.With Ram any location can be

reached in a fixed ( and short) amount of time after specifying its address.

There are two basic types of RAM :

(i) Dynamic Ram- Dynamic RAM loses its stored information in a very short time (for milli

sec.) even when power supply is on. D-RAM’s are cheaper & lower.

(ii) Static RAM- Static RAM uses a completely different technology. S-RAM retains stored

information only as long as the power supply is on. Static RAM’s are costlier and consume

more power. They have higher speed than D-RAMs.

Page 11: New Microsoft Office Word Document.docx

Some other RAMS are :

 

(a) EDO (Extended Data Output) RAM

(b) SDRAM (Synchronous DRAMS)

(c) DDR-SDRAM (Double Data Rate – SDRAM)

Printers are Output devices used to prepare permanent Output devices on paper. Printers can

be divided into two main categories :

Impact Printers : In this hammers or pins strike against a ribbon and paper to print the text.

This mechanism is known as electro-mechanical mechanism. They are of two types.

Printers are Output devices used to prepare permanent Output devices on paper. Printers

can be divided into two main categories

(i) Character Printer

(ii) Line Printer

Character Printer : It prints only one character at a time. It has relatively slower speed. Eg. Of

them are Dot matrix printers.

Dot Matrix Printer : It prints characters as combination of dots. Dot matrix printers are the

most popular among serial printers. These have a matrix of pins on the print head of the

printer which form the character. The computer memory sends one character at a time to be

printed by the printer. There is a carbon between the pins & the paper. The words get printed

on the paper when the pin strikes the carbon. There are generally 24 pins.

Page 12: New Microsoft Office Word Document.docx

Laser Printer is a type of printer that utilizes a laser beam to produce an image on a drum.

The light of the laser alters the electrical charge on the drum wherever it hits. The drum is

then rolled through a reservoir of toner, which is picked up by the charged portions of the

drum. Finally, the toner is transferred to the paper through a combination of heat and

pressure.

This is also the way copy machines work. Because an entire page is transmitted to a drum

before the toner is applied, laser printers are sometimes called page printers. There are two

other types of page printers that fall under the category of laser printers even though they do

not use lasers at all. One uses an array of LEDs to expose the drum and the other uses LCDs.

Once the drum is charged, however, they both operate like a real laser printer. One of the

chief characteristics of laser printers is their resolution – how many dots per inch (dpi) they

lay down.

The available resolutions range from 300 dpi at the low end to 1,200 dpi at the high end. In

addition to text, laser printers are very adept at printing graphics, so you need significant

amounts of memory in the printer to print high-resolution graphics. To print a full-page

graphic at 300 dpi, for example, you need at least 1 MB (megabyte) of printer RAM. For a

600 dpi graphic, you need at least 4 MB RAM.

Because laser printers are non-impact printers, they are much quieter than dotmatrix or daisy-

wheel printers. They are also relatively fast, although not as fast as some dot-matrix or daisy-

wheel printers. The speed of laser printers ranges from about 4 to 20 pages of text per minute

(ppm). A typical rate of 6ppm is equivalent to about 40 characters per second (cps).

Non-Impact Printers : There printers use non-Impact technology such as ink-jet or laser

technology. There printers provide better quality of O/P at higher speed. These printers are of

two types :

Ink-Jet Printer : It prints characters by spraying patterns of ink on the paper from a nozzle or

jet. It prints from nozzles having very fine holes, from which a specially made ink is pumped

out to create various letters and shapes. The ink comes out of the nozzle in a form of vapors.

After passing through a reflecting plate, it forms the desired letter/shape at the desired place.

Hardware

Physical components of a computer system which we can touch and feel are called Hardware.

Hardware must required to run the Software.

Computer Hardware can be broadly categorized into 2 types. 1.Input / Output Devices 2.

Processing devices

Keyboard , Mouse, Monitor, Joystick etc.. which required to give input to the computer and

capable to display the output comes under Input / Output Devices. Processor, Mother Board,

Memory etc. responsible for background operations and processing comes under Processing

Devices.

Hardware understands only Binary Digits 0s(Zeros) and 1s(Ones) in the form of voltage

pulses.

Professional and Expert in Hardware is called Hardware Engineer.

Various metals, ceramics, plastics, semiconductors, and composites are used in the making of

Hardware. Eg. Silicon, copper Plastic polymers etc..

Software

Set of Instructions called programs responsible for running computer is called Software.

Software makes Hardware to run.

Computer Software can be broadly divided into two categories 1. System Software 2.

Application Software.

Operating System of the Computer which Manages all the devices, memory, software’s of the

computer comes under System Software.Examples of System Software are Windows , Lunux

Operating Systems etc. Where as Software used for specific applications like Word

Processing, Spread sheets maintaining is called Application Software. Examples of

Application Software’s are MS Word, Excel etc.

Page 14: New Microsoft Office Word Document.docx

Software tells the Hardware everything in the form of Binary Digits 0s(Zeros) and 1s(Ones)

only.

Professional and Expert in Software is called Software Engineer.

Programming Languages are used to create Software. Eg. C, C++, Java etc..

Microsoft Access, also known as Microsoft Office Access, is a database management

system from Microsoft that combines the relational Microsoft Jet Database Engine with

a graphical user interface and software-development tools. It is a member of the Microsoft

Office suite of applications, included in the Professional and higher editions or sold

separately.

Access is now much more than a way to create desktop databases. It’s an easy-to-use tool for

quickly creating browser-based database applications that help you run your business. Your

data is automatically stored in a SQL database, so it’s more secure than ever, and you can

easily share your applications with colleagues.

Information technology (IT) is the application of computers and telecommunications

equipment to store, retrieve, transmit and manipulate data,[1] often in the context of a business

or other enterprise.[2] The term is commonly used as a synonym for computers and computer

networks, but it also encompasses other information distribution technologies such as

television and telephones. Severalindustries are associated with information technology,

including computer hardware, software, electronics, semiconductors, internet,telecom

equipment, e-commerce and computer services

Security management is the identification of an organization's assets (including information

assets), followed by the development, documentation, and implementation of policies and

procedures for protecting these assets.

An organisation uses such security management procedures as information classification, risk

assessment, and risk analysis to identify threats, categorise assets, and rate system

vulnerabilities so that they can implement effective controls.

A hard disk drive (HDD)[b] is a data storage device used for storing and

retrieving digital information using rapidly rotating disks (platters) coated with magnetic

material.[2] An HDD retains its data even when powered off. Data is read in a random-

Page 15: New Microsoft Office Word Document.docx

access manner, meaning individual blocks of data can be stored or retrieved in any order

rather than sequentially. An HDD consists of one or more rigid ("hard") rapidly rotating disks

(platters) with magnetic heads arranged on a moving actuator arm to read and write data to

the surfaces.

Desktop

The desktop is the primary user interface of a computer. When you boot up your computer,

the desktop is displayed once the startup process is complete. It includes the desktop

background (or wallpaper) andicons of files and folders you may have saved to the desktop.

In Windows, the desktop includes a task bar, which is located at the bottom of the screen by

default. 

Windows & Its Components

The main components of Windows when you start your computer are the Desktop, My

Computer,

Recycle Bin, Start Button, Taskbar, and shortcuts to applications.

After opening an application, you will also have a window with an active application which

will appear in your desktop and taskbar.

Page 16: New Microsoft Office Word Document.docx

Microsoft Excel is a spreadsheet application developed by Microsoft for Microsoft

Windows and Mac OS. It features calculation, graphing tools, pivot tables, and

a macro programming language called Visual Basic for Applications. It has been a very

widely applied spreadsheet for these platforms, especially since version 5 in 1993, and it has

replaced Lotus 1-2-3 as the industry standard for spreadsheets.

5. Click OK 

The chart will appear in your document. Additionally, an Excel worksheet opens. You can

enter your data in the worksheet. Use the handle to adjust the range of data that appears in the

chart. It will automatically update the chart in Word. 

Once your chart is created, you can use the tools in Word to change the chart style, layout and

formatting options.

TRANSMISSION MEDIA 

The means through which data is transformed from one place to another is called

transmission or communication media. There are two categories of transmission media used

in computer communications.

BOUNDED/GUIDED MEDIA

UNBOUNDED/UNGUIDED MEDIA

The Transmission Control Protocol (TCP) is one of the core protocols of the Internet protocol

suite (IP), and is so common that the entire suite is often called TCP/IP. TCP

provides reliable, ordered and error-checked delivery of a stream of octets between programs

running on computers connected to a local area network, intranet or the public Internet. It

resides at the transport layer.

The Internet Protocol (IP) is the principal communications protocol in the Internet protocol

suite for relaying datagrams across network boundaries. Its routing function

enables internetworking, and essentially establishes the Internet.

IP, as the primary protocol in the Internet layer of the Internet protocol suite, has the task of

delivering packets from the source host to the destination host solely based on the IP

addresses in the packet headers.

Page 19: New Microsoft Office Word Document.docx

Memory management is the act of managing computer memory. The essential requirement of

memory management is to provide ways to dynamically allocate portions of memory to

programs at their request, and free it for reuse when no longer needed. This is critical to any

advanced computer system where more than a single process might be underway at any time.

Mail merge is a software function describing the production of multiple (and potentially large

numbers of) documents from a single template form and a structured data source. The letter

may be sent out to many "recipients" with small changes, such as a change of address or a

change in the greeting line. Both WordStar (via an ancillary program) and WordPerfect

offered this capacity for CP/M and MS-DOS systems. MS Word Mail Merge allows a user to

send letters or documents to many people simultaneously; users simply create one document

that contains the information that will be the same in each version, and then add placeholders

for the information that will be unique to each version.

Charles Babbage, ( 26 December 1791 – 18 October 1871) was an English polymath. He

was a mathematician, philosopher, inventor and mechanical engineer, who is best

remembered now for originating the concept of a programmable computer.

Considered a "father of the computer",Babbage is credited with inventing the first mechanical

computer that eventually led to more complex designs.

 Third Generation Computers computers are …

1. Third Generation Computers were based on integrated circuit (IC) technology.

2. Third Generation Computers were able to reduce computational time from microseconds to

nanoseconds

3. Third Generation Computers devices consumed less power and generated less heat. In some

cases, air conditioning was still required.

4. The size of  Third Generation Computers was smaller as compared to previous computers

5. Since hardware of the Third Generation Computers rarely failed, the maintenance cost for it

was quite low.

6. Extensive use of high-level language became possible in Third Generation Computers.

7. Manual assembling of individual components was not required for Third

Generation Computers, so it reduced the large requirement of labor & cost. However, for

the manufacture of IC chips, highly sophisticated technologies were required

8. Commercial production became easier and cheaper.
