The functions of the different components of a conventional digital computer

01

• Data processing
• Data saving
• Data exchange
• Control

Consists of:

Output: Output Data

Control: Interprets instructions, regulate and control processor timing.

Memory: To stores all the data and the instructions required for processing.

Data exchange: is allowed to exchange and share between computers of the program.

II. Cache memory

Cache is a fast memory component used by the central processing unit (CPU) of a computer to provide faster access to frequently used program instructions or data that the CPU is likely to need next. Cache is small, fast memory that is conceptually and physically close to the CPU, thus more accessible to the

1. Define

Cache provides faster data storage and access by storing versions of programs and data that are frequently accessed by the processor. Therefore, when the processor requests data that is already in the cache, it does not need to go to main memory or the hard disk to fetch the data.

2. Why is it necessary?

3. Compare Cache and RAM?
