Components
of Computer
Well, It is generally taught that
there are four parts of computer which are mouse, keyboard, monitor and CPU.
This definition of computer is wrong. If we consider it as a true one then what
about other devices like printer, scanner, projector, etc.
All in all, this is a wrong definition which is being taught to
the student since from very beginning.Basically, there are four component of computer which includes all the devices of computer. They are hardware, software, data and user.
Hardware:
The physical parts of computer whom we can touch are called hardware. The examples include monitor, CPU, keyboard, scanner, etc

Software is simply defined as the component of computer which we cannot touch.
Software is a set of instructions which is given to the computer by the developers and called program and do our job as we direct it.
