This is known as the microprocessor. Its function is handling the interpretation and execution of programs. it is normally a single integrated circuit (IC) chip. The constituents parts of CPU are: (i) Control unit (ii) The arithmetic and logic unit (ALU) (iii) Registers
This is where the computer res the data it has to manipulate, the secondary or intermediate results, as well as the final results of its operations. The storage unit is also known as the memory Some examples of the storage components are: (i) Semiconductor memory (ii) Disk Drives (iii) Tape drives
The results of computation are made available to the user via the output unit. These include: (i) Visual Display Unit (VDU) (ii) Teletypewriter (iii) Magnetic disk (iv) Tape drives (v) Printers (vi) Plotters (vii) Card punches (viii) Spellers Note also that the digital form from input can be converted to analogue form, hence the need …
The input devices supply data needed for calculation as well as the program that tells the computer how and what to do with the data. The standard input units are: (i) The keyboard (ii) mouse (iii) scanner (iv) Digital camera (v) CD drives (vi) Magnetic disk (vii) Tape drives (viii) Joystick (ix) Voice recognition (x) …

The four basic functions performed by computer are: (i) Input functions (ii) output function (iii) Storage/retrieval functions (iv) processing operations
