Question

Draw and explain the architecture of computer system

Answer 1

Answer:

Explanation:

Computer architecture is a specification detailing how a set of software and hardware technology standards interact to form a computer system or platform. In short, computer architecture refers to how a computer system is designed and what technologies it is compatible with.

Answer 2

The explanation of the architecture of a computer system is as follows:

• The way a computer system is built together and the purpose behind the operations that direct how it works together form its architecture.
• The following are the elements that make up a computer system's architecture:

1. Central Processing Unit (CPU)

• The central processing unit (CPU) of a computer system is made up of the Arithmetic Logic Unit (ALU) and the Control Unit (CU).
• A CPU is the brain of a computer system.
• The operating system and applications are run by the CPU, which is a sophisticated collection of electronic circuits, by carrying out and integrating the given instructions.

2. Arithmetic Logic Unit (ALU)

• A computer's ALU performs mathematical and logical operations.
• The integer arithmetic and bitwise logic operations are carried out by the arithmetic unit (AU) and the logic unit (LU), two subunits of the ALU.

3. Control Unit (CU)

• By instructing the system to execute programme instructions, CU manages and controls computer operations.

4. Memory

• Main (or primary) memory and auxiliary (or secondary) memory are the two subunits that make up computer memory.
• A processor can access running programmes and services that are momentarily stored in a particular memory location using primary memory.
• Users can store data and information in secondary memory so that it can be quickly and readily retrieved, communicated, and utilized by apps and services.
• The CPU has direct access to only the primary memory; it has no direct access to the secondary memory.

5. Input Devices

• A computer can receive data in the form of text, pictures, video, or sound from an input device.
• A computer system frequently uses input devices such as a keyboard, mouse, scanner, joystick, microphone, etc.

6. Output Devices

• An output device renders the computer's intended transmission of data into a form that is comprehensible to humans.
• Projectors, speakers, headphones, printers, and monitors are a few examples of output devices that are frequently utilized.
