Components of Computer System

A system is defined as a set of interacting elements, responding to inputs so as to produce outputs. The computer system also consists of the following elements or components.

• Software
• Hardware
• Firmware
• Humanware  

Software

All the intangible components of the computer system are known as software In other words, we can say that all computer programs and applications run behind the monitor screen, are known as software. Computer software is a term that describes computer programs.

Example  Microsoft-windows (all operating system software) and notepad, MS office suite, window media player(application software).
Software is further divided into two parts these are following
1) system software
2) application software

Hardware

All tangible component of a computer system is known as hardware. In other words, computer hardware is the collection of physical parts of the computer system.
Example CPU(Microprocessor), monitor, keyboard, mouse, speaker, printer, scanner, etc. It also includes all the parts inside a computer case, such as hard disk derive, motherboard, video card, and many others.

Firmware 

Firmware can be defined as a group of software and hardware. Because in a computer system, without hardware components, the software has no meaning and without software components, hardware has no meaning i.e. both of these components are mutually dependent. Both of them must work together in order to make a computer produce some useful output. This group is known as firmware.

Example All the software applications or programs are installed in the hard disk which is a hardware component.

Humanware

A user or an operator, who uses the computer machine, is known as humanware can be a computer professional, a student,  a novice user(beginner) or any other person, who operates this machine for completing his/her task.
