We defined computer as an electronic device that accepts input from an input device, the CPU processes it and output the result via the output device (VDU). The characteristics of a computer include speed, accuracy, diligence, versatility, power of remembering, no IQ, no Feeling and storage capacity.
A computer system has various components which can be classified into four groups; input unit, memory unit, central processing unit and the output unit.
The computer hardware is the physical part of a computer that can be touched and seen while computer software are programs that perform a well-defined function. We noted that the two types of computer software are: Application and System software.
