Computer hardware includes the physical, tangible parts of components of a computer, such as the cabinet, central processing unit, monitor, keyboard, computer data storage, graphics card, sound card, speaker and motherboard. By contrast, software is a instruction that can be stored and run by hardware.
- CPU ( Central Processing Unit )
➤ ALU ( Arithmetical & Logical Unit )
➤ MU ( Memory Unit )
➤ CU ( Control Unit )
- Peripheral Devices ( External Devices )
➤ Input Device
➤ Output Device
- CPU ( Central Processing Unit )
CPU is the microprocessor of our computer system.
➝ It is considered as brain of our computer system.
➝ It is the central that perform comparison, calculation, read and write and control the execution of the instruction provided.
The CPU have three different units ---
➤ ALU - It is used to perform all the calculations like addition, subtraction, multiplication and division. It also take comparison and logical decisions such as <, >, < =, > =, =, ≠.
➤ CU - This unit supervise the operation of entire computer system. It select the program scattering from the memory unit and then transfer it to ALU for proper processing.
➤ MU - It is also called register. It store all the data which has been process and also store immediate result of processing.
The final results can be exist using output devices.
