There are mainly two parts of computer system
Hardware
The physical parts of computer that the user can touch is called hardware.
Example-
Mouse, Keyboard, monitor, printer, scanner, plotter, CPU etc.
Software
The set of program used to operate computer that the user can not touch only feel is called software.
Example-
Microsoft word, Microsoft excel, paint, operating system etc.
Input Devices
The hardware parts of computer that are used to insert data from user to CPU is called Input devices.
These are-----------
Keyboard
Output Devices
The hardware parts of computer that are used to send data from CPU to user to Output devices.
These are-----------
VDU / MONITOR
