- a component of a computer system, which refers to the set of instructions (program) written in a code.Software

3 Types of Software:1. Systems Software consists of low-level programs that interact with the computer at a very basic level.Common Types of Systems Software:1. Operating System/OS manages and coordinates the functions performed by the computer hardware. Ex. MS-DOS, Xenix, Mac OS, OS/2, UNIX, MVS 2. Assemblers a program that translate/assemble into machine code.

Common Types of Systems Software:3. Compilers a program that translates source code into a set of machine-language instructions that can be understood by a digital computer's CPU.4. Debuggers checks the program if errors exists. 5. Utilities - is a program that performs a very specific task, usually related to managing system resources. Ex. AVG Anti-Virus.

1. Word Processor- a word processing program is designed primarily to edit text. Ex. WordStar, Microsoft Word, OpenOffice Writer1. Application Software which directs the computer to execute commands that solve practical problems.Common Types of Application Software:

2. Spreadsheets are primarily designed for maintaining numerical tables, and calculating formulas using the figures entered into the spreadsheet. Ex. Lotus123, Quattro, Microsoft Excel, OpenOffice Calc

3. Presentation - an application use to help us to be creative in making a presentation which is simple and easy way. Ex. Microsoft PowerPoint, OpenOffice Impress

4. Databases a database program stores huge quantities of information and organizes them by any number of specified categories. Ex. OpenOffice Base, Microsoft Access, MySQL, SysBase

5. Desktop Publishing/DTP software takes document preparation a step beyond what word processors can do. Ex. Desktop Publisher

6. Graphics Program let you draw and paint on your computer. Ex. Paint, OpenOffice Draw, Dia Diagrams, CorelDraw, GIMP

7. Computer-Aided Design/CAD programs are very technically-oriented applications and have powerful mathematics and visual modeling capabilities. Ex. AutoCad

3. Programming Language a language in which a computer programmer writes instructions for a computer to execute.Common Programming Languages:1. Beginner's All-purpose Symbolic Instruction Code/BASIC 2. Visual Programming Language(Visual Basic/VB, Visual Foxpro, Visual C++)3. C Language4. Common Business Oriented Language/COBOL5. Formulas Translation/FORTRAN6. Pascal Language7. Java Language
