Definition
of Computer:
Computer perform following basic Operations in Sequence:
1. 1. It
receives data and instructions from the input devices.
2. 2. Process
the data as per instructions.
3. 3. Provide
result (output) in a desired form.
Advantages
of Computer:
1. High speed:
Computer have the ability to perform routine
task at a greater speed then Human
beings. They can perform billions of calculations in second.
2. Accuracy:
Computers
are used to perform tasks in way that ensure accuracy.
3. Storage:
Computers can store large amount of information. Any item of data or any
instructions stored in the memory can be retrieved by the computer at lightning
speed.
4. Automation:
Computers can be instructed to perform complex tasks automatically (which
increase the productivities).
5. Diligence: Computers can
perform the same tasks repeatedly and with the same accuracy without getting
tried.
6. Versatility: Computers are fixable to perform both simple
and complex tasks.
7. Cost effectiveness: This is to expensive.
Characteristics
of Computer:
1. 1. Store
a large amount of data and information for large period.
2. 2. Process
the data and information in accuracy level.
3. 3. Speed
and processing data and information.
