The major elements of the computer system are as follows –
- Memory
- ALU
- Control Unit
- Hardware and Software
1. Memory
Memory is also known as the storage medium of the computer system. This is a storage device that can store data/information. Memory is primarily categorized into two parts,
- Primary Memory:
This is also known as the main memory or temporary memory or volatile memory. This memory device stores data for a temporary period. Programs or instructions execute in Primary Memory.
Primary Memory further categorized into two parts –
- RAM (Random Access Memory)
- ROM (Read Only Memory)
- Secondary Memory:
Secondary memory is a memory that can store a large amount of data in it. Once, data is saved into secondary memory cannot delete until and unless the user's permission. It is also known as a permanent memory.
2. ALU
ALU stands for the Arithmetic and Logical Unit. This is an important element of the computer system which is used to perform arithmetic and logical operations. ALU is a part of a computer processor.
3. Control Unit
Control Unit controls all the devices connected to the computer system so that interrupt or unavoidable circumstances between device communications cannot happen. CU not only controls device communication but also program executions. CU mainly communicates between processor, memory and computer peripherals (input/output devices).
4. Hardware and Software
Hardware is the tangible components of the computer system which can be used to give input, store data and showing results. The popular hardwares are mouse, keyboard, monitor, printer, processor, motherboard, cables, etc.
