Topic: Internal Features Of the System Unit
(CPU) The central processing unit is the brain of the computer system. It is responsible for all processing activities that take place within the computer system. It is also responsible for processing data given meaningful information.
Component Of the CPU
The cup consist of the three components
- The Control.
- The arithmetic and logic unit: this is the unit responsible for carrying out arithmetic operation such as addition, subtraction, multiplication and division on data. It also carries out logical operation such as comparing two items ( e.g >, <, =, etc)
- Main memory: this is the unit that supervise, control and coordinates the execution of the program in a correct order.
It ensures the smooth operation of the hardware components, fetches and interprets instruction to the unit responsible for executing the instructions.
Main Memory: this is the part or the cpu that stores data to be processed well as the instruction for processing them. Data must be stored inside the main memory before they can be processed into information. It can also be called the main storage and primary storage.
