COMPUTING FUNDAMETAL

01

The functions of the different components of a conventional digital computer

Consists of:

• Data processing
• Data saving
• Data exchange
• Control

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

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

Control: Interprets instructions, regulate and control processor timing.

Output: Output Data

Input: Input data

1. Define

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

II. Cache memory

2. Why is it necessary?

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.

3. Compare Cache and RAM?

III. Operating System

"The software that supports a computer's basic functions, such as scheduling tasks, executing applications, and controlling peripherals."

It allows you to manipulate the computer

2. Role of the operating system

Acts as an intermediary in the communication between the user and the device.Full management of all components (including hardware and software) of electronic equipment. Acts as an intermediary in the communication between the user and the device.

An operating system is the most important software that runs on a compute. It manages the computer's memory and processes, as well as all of its software and hardware.
