Definition of Software

Software is a set of instructions and procedures passed to the computer to perform certain activities or task. It can also be defined as a set of instructions that direct the activities of the computer system in order to undertake a specific task. Unlike the hardware, software cannot be seen or touched.

Types of Software

Software is divided into two broad groups, these are:
1. System Software
2. Application software

1. System Software
These are software that control the way the different computer components communicate with one another. It can also be defined as programs that help run the computer hardware and software. The system software consists of programs, written by manufacturers, which contributes to the proper control and good performance of the computer system. System software generally comprises three groups. These are:
a. Operating system
b. Utility software
c. Translators

a. Operating system: Operating (OS) is software program that manages the hardware and software resources of the computer. Examples Disk Operating System (DOS), Microsoft windows, UNIX, LINUX, MAC etc
Utility software: utility software (service programs) are used for general housekeeping of the computer such as repairing the computer, backing up files, copying, sorting and printing. Examples of utility programs include: window explorer, Anti-virus, Network manager, Registry cleaner, data compression utilities, etc
Translators: Translators are programs for converting programs in other languages into machine language instruction so that the computer can execute them. Examples include assembler, compiler and interpreter.

System

2. Application Software
These are software that allows humans to accomplish one or more specific (non-computer) task.
There are different types of application software, they include:
a. Word processing software : These are software used for creating, editing and printing document. Example include: Microsoft Word, Notepad, Corel WordPerfect, WordPad, etc.
b. Spreadsheet software: These are software for performing accounting and statistical calculations. Examples are: Microsoft Excel, Lotus 1-2-3, etc.
c. Graphics software : These are software that are used for drawing and designing purposes, examples CorelDraw, Paint, Photoshop, Instant Artist, etc.
d. Database Application: Database software allows you to enter, retrieve and update data in an organized and efficient manner. Commonly used database programs include Microsoft Access and Lotus 1-2-3
e. Presentation: A presentation program is a computer software package used to display information, normally in the form of a slide show. Examples are MS power point Corel Presentations, OpenOffice.org Impress, SlideSlider, SlideRocket SlideWiki, Audience (software), Ease, Emaze, WPS presentation, etc
