A computer system consists of mainly four basic units; namely input unit‚ storage unit‚ central processing unit and output unit. Central Processing unit further includes Arithmetic logic unit and control unit‚ as shown in the figure:. A computer performs five major operations or functions irrespective of its size and make. These are • it accepts data or instructions as input‚ • it stores data and instruction • it processes data as per the instructions‚ • it controls all operations inside a computer

What are the Parts of Computer? The Parts of a Desktop Computer are: 1. System unit The system unit is the core of a computer system. Usually it’s a rectangular box placed on or underneath your desk. Inside this box are many electronic components that process information. The most important of these components is the central processing unit (CPU)‚ or microprocessor‚ which acts as the "brain" of your computer. Another component is random access memory (RAM)‚ which temporarily stores
