Types of Computer Software


Software is a set of instructions that tells computers how to operate. These instructions are written in a programming language that the hardware understands.

There are two types of software: application software and system software. System software includes the operating system, which coordinates the activities of a computer’s application programs and hardware.

Word Processor

Word processors facilitate writing and editing, especially with the ability to copy and move text (“cut-and-paste”), their built-in dictionaries to check spelling, and their grammar checkers. They are also capable of creating, storing, and printing documents and providing file handling commands such as Load, Save, and Save As.

Most modern word processors take advantage of a graphical user interface, usually providing some form of what-you-see-is-what-you-get editing (WYSIWYG). This enables users to easily format characters, paragraphs, and pages.

They are also capable of incorporating graphics, clip art, charts, and images into a document. Some allow the use of a thesaurus to look up alternative words without leaving the program. They can also generate mailers and labels and import data from CSV or a database. Some even allow multiple people to work on a document at the same time, a feature that traditional word processing programs lack.


Multimedia is a type of computer software which allows for the integration of text, graphics, images, audio and video. It is used in many different applications including marketing, advertising, product demonstrations and presentations.

The main function of multimedia is to give an idea in a visual form, making it easier for people to understand it. This software also helps to increase information retention as well as engagement with the content.

Multimedia is an excellent way to share information with the public and can be a great way to promote businesses or services. It can be used for all types of audiences and can even be accessed from anywhere using mobile devices. However, it is important to choose the right type of software for your needs.


Spreadsheets are computer applications that can be used to create and manage a variety of data in tabular form. They can be used for many different purposes, such as budgeting, estimating expenses, planning projects, accounting, and more.

Most spreadsheet programs use a grid system of rows and columns. Each cell references a value, usually a number. The cells are labeled according to their placement, and can be resized so you can easily view your information.

A spreadsheet program may allow a user to write formulas that mechanically compute new values from the values in the cells. The spreadsheet may then automatically update the cells when their formulas depend on changes in the data.


A database is a collection of information that is organized and stored in one or more files. It may be used to store personal data, business information, or research results.

A DBMS (database management system) is a software program that controls the operation of databases. Various DBMSs have features to protect data integrity, such as checksumming and write-ahead logs.

DBMSs also include tools for database design, application programming, application program maintenance, and performance analysis. These tools often provide user interfaces to select DBMS parameters, like security related and storage allocation.

A DBMS optimizes the organization of data by using a database schema design technique called normalization. This process splits large tables into smaller ones when any of their attributes have redundancy in values. This helps to increase data availability and decrease storage costs.


Simulation is a type of computer software that simulates the behavior of a system or object in response to changes in conditions. It is used in engineering, chemistry, medicine, weather forecasting, and many other computationally intensive fields.

In the field of social science, computer-based simulations allow social scientists to test theories in a more controlled environment than could otherwise be accomplished. It also allows social scientists to investigate ‘artificial societies’, or simulated environments that mimic life in some ways.

Discrete-event systems, such as production assembly lines, health services, and telecommunication networks, are the primary focus of simulation research. In order to be effective for design purposes, simulation must be linked with mathematical optimization techniques.
