This document discusses different types of computer software. It defines software as computer instructions or data that can be stored electronically, while hardware refers to the tangible parts of a computer. The document outlines two main types of software: system software and application software. System software manages and controls hardware, and includes operating systems and compilers. Application software does real work for users, such as word processors, spreadsheets, and databases. Examples of each type are provided.

3. INTRODUCTION TO
COMPUTER SOFTWARE

4. Software & Hardware?
■ Computer Instructions or data, anything that can be stored
electronically is Software.
■ Hardware is one that is tangible. The storage devices (Ha
etc.,), mouse, keyboard CPU and display devices (Monitor)
Hardware.
For example: There is a problem in the Software implies – P
program or data

5. TYPES OF SOFTWARE
System Software
Application Software

6. System Software:
System Software includes the Operating System and all
the utilities that enable the computer to function.
System software is a term referring to any computer
software which manages and controls the hardware so
that application software can perform a task.
. Example:
Operating Systems, Compiler etc.

7. Application Software:
Application Software includes programs that do real w
for user.
Example:
Manage student database, Word Processor, Spreadshee
and Database Management System etc.,

8. System Software:
Operating System:
■ Operating System is a software, which makes a computer to
actually work.
■ It is the software the enables all the programs we use.
■ The OS organizes and controls the hardware.
■ OS acts as an interface between the application programs
and the machine hardware.
■ Examples: Windows, Linux, Unix etc.,

9. System Software (contd...):
Source
Languages
Target Languages
‘C’ language ‘C’ language
‘Pascal’ language Machine language
FORTRAN language
C++ language
ADA language
Compiler: A compiler is a program that reads a
program in one language – the source language and
translates into an equivalent program in another
language – the target language.

10. Application Software:
Word Processors:
Word processing is a tool that helps user in creating,
editing, and printing documents. Word processors will
normally have the following capabilities built into
them:
■ Spell checking
■ Standard layouts for normal documents
■ Have some characters appear in bold
print, italics, or underlined
■ Center lines, make text line up on the
left side of the paper, or the right side of
the paper
■ Save the document so it can be used
again
■ print the document.
Examples: WordPerfect and Microsoft Word

11. Application Software
(contd…):
Spreadsheets: The spreadsheet packages are
designed to use numbers and formulas to do calculations
with ease. Examples of spreadsheets include:
■ Grade Calculations
■ Address Lists
The most commonly used spreadsheet programs are
Microsoft Excel.
