This document provides an overview of different types of software. It defines software as a set of electronic instructions that tells a computer how to perform tasks. There are two main types of software: system software and application software. System software includes operating systems, diagnostic routines, and basic input/output systems. Application software allows users to perform tasks like word processing, using spreadsheets, managing databases, and performing graphics/communications. The document outlines common examples of application software within each category.

- 4. What is Software? Software is a set of electronic instructions that tells the computer how to do certain tasks. A set of instructions is often called a program. When a computer is using a particular program, it is said to be running or executing the program. The two most common types of programs are system software and application software. CIC

- 7. System Software A System software exists primarily for the computer itself, to help the computer perform specific functions. One major type of system software is the operating system (OS). All computers require an operating system. The OS tells the computer how to interact with the user and its own devices. Common operating systems include Windows, the Macintosh OS, OS/2, Linux, and UNIX. CIC
- 8. Kinds of System Software System Software Consists of Four (4) Kinds of Programs: Bootstrap Loader It is a program that s stored permanently in the computer’s electronic circuitry. When the computer is turned on, the bootstrap loader obtains the operating system from the hard disk and loads it into the memory. This is called “BOOTING” the system. Diagnostic Routines It is a programs stored in the computer’s electronic circuitry. They test the primary storage, the CPU, and other parts of the system to make sure the computer is running properly. CIC
- 9. Kinds of System Software Basic Input-Output System Consist of service programs stored in primary storage. These programs enable the computer to interpret keyboardcharacters or transmit characters to the monitor or to a disk. Operating System Collection of programs that helps the computer manages its resources. The operating system takes care of a lot of internal matters in order for the computer to run smoothly. CIC
- 10. Application Software Application software tells the computer how to accomplish tasks the user requires, such as creating a document or editing a graphic image. CIC
- 11. Types of Application Software Word Processing Word processing software creates, edits, saves, and prints documents. Examples of packages: MS Word, WordPerfect, Ami Pro, MacWrite. Spreadsheets An electronic spreadsheet consisting of rows and columns is used to present and analyze data. Examples of packages: MS Excel, Lotus 123, Quattro Pro. CIC
- 12. Types of Application Software Database Management Database management software is used to structure a database, a large collection of computer programs. Data is organized as fields and records for easy retrieval. Example of packages: MS Access, dBase, Fox Pro, Oracle Graphics Software Graphics programs display results of data manipulation for easier analysis and presentation. Examples of packages: MS PowerPoint, Macromedia Flash, Harvard Graphics, 3D Studio Max CIC
