Short Questions and Answers according to new Syllabus of Islamabad Board

hat is data? Data is defined as; collection of raw facts and figures, which is collected for specific purpose.

The data may be in

the form of text, numbers, sounds, images, video clips etc.•

efine inform When raw facts & figures are arranged in such a suitable manner that they give the clear & proper meanings then

they

are called information.

efine data p data processing is defined as: a sequence of operations performed on data to convert it into useful information.

Data

processing is also known as computing.

efine inform A system that processes the raw data to convert it into useful information is referred to as information

system.

An

information system or computer-based system includes hardware, software, data, procedures and the users that interact with the computer. The data is provided to the information system and processed information is obtained.

hat is infor information technology is a technology that combines computing with high-speed communication links for carrying data from one place to another, all over the world (i.e. over this global village).

hat is a c A computer is an electronic machine that can be programmed to accept data (input), process it into useful

information (output), and store it in a secondary storage device for data reuse.

efine har Hardware is physical components of a computer. You can touch, see and feel hardware. The computer

along with input/output devices is known as hardware.

efine sof A set instructions given to the computer to perform a specific task, is called software (or computer program). It tells the computer what to do and how to do.

hat is sy A program or set of programs that is specially designed to control the computer system is called system

software. The system software also enables the other application programs to execute.

Operating systems

and

device drivers are the examples of system software.

hat is pa These are the programs that are developed by software development organizations and sold on the open market to any customer. Actually, these softwares are developed to provide common applications on a computer. The examples of these softwares are Ms-Word, Ms-PowerPoint, MsAccess, Oracle etc.

hat is inp The devices that are used to enter data and instructions into the computer are input devices. The input device accepts input (data & programs) in a form that the computer can use, and then sends to the

processing unit.

hat are p A pointing device is an input device that is used to control the position of the pointer or cursor on the

screen

and to send command signals to the computer. Usually, the pointing

device is used to select items on the screen, to select commands from commands menu, to draw graphs etc.

hat is Tr A trackball is also a pointing input device. It performs functions like a mouse but it is a stationary device with a moveable ball on its top. The ball is rotated or rolled with fingers (or palm of the hand).

Basic Concept of Information Technology #1 Class XI Compiled by Wasim Anjum Farooqi (M.Ed., MCS.) Touch Pad is a pointing input device. It is also stationary device like trackball. It is a small, flat surface

over which we slide our fingertip to move the pointer on screen for pointing a desired

icon (or item). As we slide our fingertip on the flat surface of Touch Pad, the cursor follows the movement.

hat is UP Data coded in the form of light and dark vertical lines (or vertical zebra-stripped marks) or bars on most

of

the manufactured products in the market are known as bar codes. This bar-code

system is also called the

Universal Product Code (UPC).

cards are used for personal identification during driving, in the departmental

stores, at public places etc.

hat is sm Smart card looks like a credit card but in most of these cards, a microprocessor and memory chip is

added also When this card is inserted into a reader (a device used to read the card), it

exchanges data

with the corresponding information on a central computer. It can store some basic

information also. A

mobile SIM card and an ATM card are examples of smart cards.

drum with laser beam and magnetically charged powered ink, called toner, and

then transfers the

image from drum on the paper.

efine Co Coding is the main phase of system development process. In this phase, the actual codes of software are

written. It means that actual system is produced.

efine par In this way, the new system is run parallel to the old system. The outputs returned by both systems are

compared. If the working and output of new system is better than old system

then the working of old system is stopped.
