Classification of computer system

1.     Computer hardware

2.     Computer software

3.     Computer firmware

4.     Computer live ware

Computer hardware

The physical accessories belongs to a computer system are called computer hardware. They can be touched and seen, but cannot be taken apart easily.

Eg:- keyboard, mouse, monitor. They are the main 3 computer hardware and the rest are called computer accessories.

The function of these components is typically divided in to three main categories: input , output, and storage. Components in these categories connect to microprocessors, specifically the CPU via wires or circuitry called bus.

Computer software

Computer software is a collection of computer programs and related data that provide the instruction step by step for telling the computer what to do and how to do it. In other words, software is a conceptual entity which is a set of computer program procedures algorithm and associated documentation concerned with the operation of a data processing system. In contrast to hardware software is intangible, means it cannot be touched.  Therefore a piece of software that can be run on a particular computer system is properly designed to perform a specific task. Software is often divided in two categories: system software and application software.

System software: - Includes the operating system and all the utilities that enable the computer to function.

Application software: - includes programs that do real work for users. For e.g.:- word processors, spreadsheets, and database management systems fall under the category of application software.
