Task 2

System Software:-

• Generally, programs written to service other programs


• Heavy interaction with computer hardware


• Heavy usage by multiple users


• Concurrent operation that requires scheduling


• Resource sharing and sophisticated process management


• Complex data structures


• Multiple external interfaces


• Example :-
  
  
  
  1. OS – MS Windows, Linux Ubuntu
  
  
  2. Drivers – printer driver
  
  
  3. Networking software - wireless networking software
  
  
  4. Telecommunication software – messaging system such as sms, mms
  
  
  5. Compilers – Borland C++, Turbo C
  
  
  
  

Application Software:-

• Stand alone program that solve a specific business need


• Process business or technical data in a way that facilitates business operations
  
• Is used to control business functions in real-time


• Contrasted with system software and middleware, which manage and integrate
  a computer ‘s capabilities


• But typically do not directly apply them in performance of task that benefit the user


• Example :-
  
  
  
  1. Point-of-sale
  
  
  2. Transaction processing
  
  
  3. Real time manufacturing process control
  
  
  4. Security tools – Avast Antivirus
  
  
  5. Media tools – GOM player
  
  
  
  

Engineering/scientific Software:-

• Early year, characterized by “number crunching” algorithms


• Range from automotive stress analysis to space shuttle orbital dynamics and from
  molecular biology to automated manufacturing


• But now, it has changed to conventional numerical algorithms


• Including computer-aided design, system stimulator and other interactive
  applications


• Example :-
  
  
  
  1. Auto-CAD
  
  
  2. Molecular visualization
  
  
  3. Flight simulator
  
  
  4. Statistical Analysis Software
     
  
  
  5. Diagnostic Software
     
  
  
  
  

Embedded Software:-

• Resides within a product or system


• Used to implement and control features and functions for the end user and for the system itself


• Can perform limited and esoteric functions or provide significant functions and
  control capability


• Example :-
  
  
  
  1. Key pad control for microwave oven
  
  
  2. Digital functions in an automobile
  
  
  3. Barcode scanner
  
  
  4. Infra red
  
  
  5. Bluetooth
  
  
  
  

Product-line Software:-

• Designed to provide a specific capability for use by many different customer


• Can focus on limited and esoteric marketplace or address mass consumer markets


• Example :-
  
  
  
  1. Inventory control products
  
  
  2. Word processing and spreadsheets
  
  
  3. Computer graphics
  
  
  4. Database management
  
  
  5. Personal or business financial applications
  
  
  
  
  
  

Web Applications:-

• Also known as “WebApps”, this network-centric software category spans a wide
  array of applications


• WebApps can be a little more than a set of linked hypertext files that present
  information using text and limited graphics


• However, as Web 2.0 emerges, WebApps are evolving into sophisticated computing
  environments that not only provide stand-alone features, computing functions, and
  content to the end user, but also are integrated with corporate databases and
  business applications


• Examples :-
  
  
  
  1. Joomla
  
  
  2. Google
  
  
  3. Yahoo
  
  
  4. MySQL
  
  
  5. PHP
  
  
  
  
  
  

Artificial Intelligence Software:-

• Make use of non numerical algorithms to solve a complex problems that are not
  amenable to computation or straightforward analysis


• Applications within this area include robotics, expert system pattern recognition, artificial neural networks, theorem proving, and game playing


• Examples :-
  


1. Image recognition


2. Voice recognition


3. Company Of Heroes


4. Chess


5. Dota
