What is Computer?
The word computer is derived from a word Compute which means “To Calculate”. So, simply we can say. “Computer is a calculating device.”
In an other definition we say.
“Computer is a device that converts data into information according to given instructions.”
Working of Computer:
Computer convert data into information using a 4-steps process called IPC
(Information Process Cycle).The word computer is derived from a word Compute which means “To Calculate”. So, simply we can say. “Computer is a calculating device.”
In an other definition we say.
“Computer is a device that converts data into information according to given instructions.”
Working of Computer:
Computer convert data into information using a 4-steps process called IPC
In IPC 1st Step è Data will be given in computer (input stage).
2nd step è Computer will process that data to generate useful information (Processing Stage).
I P C3rd Step è Computer will store the result (Storage stage).
4th Step è Computer will displayed result (Output Stage).
For example if you want result of 2+2 by computer then IPC work as;
Input Stage 2+2 will given in computer
Processing Stage 2+2 = 4 the result will be calculated
Storage Stage 4 will be store in computer.
Output Stage 4 will be displayed on screen
Here what is meant by Data & Information?
Data. “Individual or raw facts about any things called Data”. e.g. Ali, 50, RS etc
Information. “Data after processing to give a useful and complete meaning is called Information”.
Here question is that why this device is being too much popular? This is due to following reason.
Characteristics of Computer:
1: Speed.

Characteristics of Computer:
1: Speed.
Computer is a speedy device. A problem that a man can solve in hours, can be solved by computer in mill & micro seconds.
2: Storage Capacity.
2: Storage Capacity.
Computer is used due to its large storage capacity. A data that you can place in 100 (7x4) feet almirah can be stored in a computer on a 2x2 inch area.
3: Reliability.
3: Reliability.
Computer is too much reliable it not give wrong result and never tired if you use it continuously. So is accurate and tireless machine.
4: Adoptability.
4: Adoptability.
Computer has ability to work with and to control each and every electronic device. Your can plug camera, motors, fax and many other machines with it to get required result.
Usage of Computer:
Due to above characteristics computer is being used in each and every field of life. Computer is working as part of other machines as well as a separate machine. Computer is being used in Households, Robotics Technology, Offices, Industries, Banks, Railway, Airlines, Hotels to keep record, Universities for research, in data communication and Telecommunication, for Online reservation, online shopping and online banking etc.
