Fundamentals of Computer Hardware

Introduction to Computers

The term “Computer” is derived from the word ‘compute’, which means to calculate. A

computer is an electronic data processing system, which works very fast and capable of

performing both arithmetic and logical functions.

Computer performs the following 3 operations in a sequence:

1. Accepts input data

2. Stores and processes the data in rapid speeds

3. Outputs the required information in desired format.

Characteristics of a computer are:

1. responds to a specific set of instructions in a well-defined manner.

2. can execute a prerecorded list of instructions.

Advantages of computers:

1. High speed: Computers have the ability to perform routine tasks at a greater

speed than human beings. They can perform millions of calculations in seconds.

2. Accuracy: Computers are used to perform tasks in a way that ensures accuracy.

3. Storage: Computers can store large amount of information. Any item of data or

any instruction stored in the memory can be retrieved by the computer at

lightning speeds.

4. Automation: Computers can be instructed to perform complex tasks automatically

(which increases the productivity).

5. Diligence: Computers can perform the same task repeatedly & with the same

accuracy without getting tired.

6. Versatility: Computers are flexible to perform both simple and complex tasks.

7. Cost effectiveness: Computers reduce the amount of paper work and human

effort, thereby reducing costs.

Limitations of computers:

1. Computers need clear & complete instructions to perform a task accurately. If the

instructions are not clear & complete, the computer will not produce the required result.
