Answer 2

Answer:

1.1 Computer types

A computer can be defined as a fast electronic calculating machine that accepts the

(data) digitized input information process it as per the list of internally stored instructions and produces the resulting information.

List of instructions are called programs & internal storage is called computer memory. The different types of computers are

1.Personal computers: This is the most common type found in homes, schools, Business offices etc., It is the most common type of desk top computers with processing and storage units along with various in put and out put devices.

2.Note book computers: These are compact and portable versions of PC

3.Work stations: - These have high resolution input/output (I/O) graphics capability, but with same dimensions as that of desktop computer.

These are used in engineering applications of interactive design work.

4.Enterprise systems: -

These are used for business data processing in medium to large corporations that require much more computing power and storage

capacity than work stations. Internet associated with servers have become a dominant worldwide source of all types of information.

5.Super computers: - These are used for large scale numerical calculations required in the applications like weather forecasting etc.,

1.2 Functional unit

A computer consists of five functionally independent main parts input, memory, arithmetic logic unit (ALU), output and control unit.
