2. How it works?

3. Which thing interlink between the machine and a screen on which we work?

2 Major Types of Software

1: System Software 2: Application Software

6

1: System Software Programs that generally perform the background tasks in a computer. These programs, many times, communicate directly to the Hardware

Application Software

2: Application SoftwarePrograms that generally

interact with the user to perform work that is useful to the user.

These programs generally communicate to the Hardware through the assistance of system Software

Application Software

• Application Software are programs that interact directly with the user for the performance of a certain type of work

• They generally do not communicate to the Hardware (i.e. printer, disk drive, etc) directly, but through interfaces provided by the Operating System.

Confusion About Classification

• At times two persons may disagree on Software classification

• For example, some call “notepad” an application Software, whereas others call it a utility, and therefore a system Software

12

Attributes of Good Application Software

• Easy to install, un-install

– Consistent– Intuitive (Sensitive)– Configurable– Adapts to the users need

• Has a tutorial and a complete help manual

• Does not have any critical bugs13

Classification According to the Mode in which it is Used

• Interactive-mode

The user runs the program on the computer and keeps on interacting with the computer while the program runs

– Example: Word processor

14

Batch-modeThe user starts the program and the

computer processes the provided data and produces results without any further intervention from the user

Example: Payroll

Classification According to Application Area

There are Various software which are used in the following application areas:

– Religious– Scientific/engineering/graphics– Business– Productivity (industries)– Entertainment– Educational

16

Scientific Software

• Simulation of natural systems– Deforestation and effect on green-house gases

• Simulation of artificial systems– Neural Ware (Simulator for artificial neural

networks)

– Thermo-nuclear explosions

17

18

Mathematical Software:

Mathematica Can do hundreds, if not thousands of functions.

Such that solving a differential equations quadratic equation, etc.

Engineering Software• Computer-aided design (CAD)

– AutoCAD– SPICE– Virtual wind tunnels

• Computer-aided manufacturing (CAM)

• Telecommunication system Software– Centrex

• Industrial control Software– Control program for a water treatment plant

19

Graphics & Animation Software

Two types:

1. Vector graphics• Treats everything that is drawn as an object

• Relatively small file size

• Example: Flash

Moving graphics

e.g. cartoons

20

Graphics & Animation Software2. Bit-mapped or raster graphics

• Treats everything that is drawn as a bit-map

• Relatively large file size

• Example:

– MS Paint

– Adobe Photoshop

21

Business Applications

– Payroll– General ledger– Order entry– Accounts receivable & accounts payable– Inventory control

22

E-Commerce Software

Example in stock exchange:

Stock changes and rating software's.

IBM’s Web Sphere Software makes the process easier

23

Productivity Software• Common features

– Ability to simplify, automate everyday business tasks– Highly interactive and user-friendly design– Most users do not use 90% of the Software features

• Popular productivity Software– Word Processing -- Spreadsheets– Presentations -- Databases

• Examples: MS Office, Corel WordPerfect Office, Lotus SmartSuite, Star Office

24

Spreadsheet Software

• Consist of cells arranged in rows & columns

• Each cell may contain numeric values, text or formulas

• Automation– Recalculations– Charts

Common Example: Microsoft Excel

25

Presentation Development Software

• Used to prepare multimedia material for lectures & presentations to display key points, graphics, animation, or video with the help of multimedia projectors

• Advantages:– Easy to modify– Can be sent electronically– Its multimedia nature makes it more interesting for

the audience26

Small-Scale Databases Software

• Easy to use applications designed for efficient storage and fast and easy retrieval of data

• That data may be in the form of numbers, text, or even multimedia, i.e. sounds, graphics, animation, video

• Example: One may use a small database to keep track of the addresses, etc. of their business contacts such that Ms . Access

27

Entertainment Software

Key feature:

–Simple

–intuitive(sensitive)

• Both Microsoft & Apple are pursuing a PC-as-a-personal-entertainment-hub strategy.

28

Music & Video Players

• Music players (WinAmp)

• Video/Music players (Real player, Windows Media player, QuickTime player)

29

Games

• Many types– Educational– Strategy/Simulation– Sports– Shoot’em ups

• The saddest aspect: You do not need any opponents or partners to play computer games

30

Educational Software

• Category with probably the highest growth rate

• Current focus on augmenting traditional training and education methods, but it is shifting towards replacing traditional methods

31

Electronic Encyclopedias• Great resource of useful information presented

in a very interesting format

E-Dictionaries : Ms.Encarta, Britannica

• Superior to the paper-based version:

– Access speed

– Can contain animation and sound

– Much lower cost as thousand’s of pages, dozens of volumes have been replaced by a couple of CD’s
