Software is the most important component of computer system. Without software, a computer turns into a dead body – a dead slave!
Software is a generic term for organized collections of computer data and instructions, often broken into two major categories: system software that provides the basic non-task-specific functions of the computer, and application software which is used by users to accomplish specific tasks. – Wikipedia
In other words, software is a set of programs, procedures, algorithms and its documentation concerned with the operation of a data processing system. Thus the software contains the instructions that tell a computer what to do and how to do to solve a specific problem.
In general use, by software we understand a group of programs to make a system run. A program contains instructions or commands to perform a task. The term package or suite is used to describe a group of related software.
Types of Software
Software is generally classified into two groups – system software and application software. Some people prefer three types: system, application and utilities.
System Software
System software is responsible for controlling, integrating, and managing the individual hardware components of a computer system so that other software and the users of the system see it as a functional unit without having to be concerned with the low-level details such as transferring data from memory to disk, or rendering text onto a display. Generally, system software consists of an operating system and some fundamental utilities such as disk formatters, file managers, display managers, text editors, user authentication (login) and management tools, and networking and device control software.
There are three type of software under system software: Operating Systems, Language & Language Processors and Utilities.
