Software
-
Software can be further broken down in to two categories, system and application software
What is system software?
-
System software is software essential for the operation of the computer system
-
Without system software a user has no starting point for giving a computer instructions, system software gives users a platform to run applications and carry out tasks
-
Essential functions carried out by system software include:
-
Booting up – talking to hardware in order to get it ready to be used
-
Device management – managing external hardware such as keyboards, printers etc.
-
Security – gives a layer of security to the hardware, preventing malware
-
What is application software?
-
Application software (abbreviated ‘apps’) is software chosen by a user to help them carry out a specific task
-
Application software is installed on top of system software and is user chosen to best suit induvial requirements
-
Common categories of application software include:
-
Productivity – get things done efficiently (word processors, spreadsheets & presentation)
-
Communication – stay connected (email, browser, messaging)
-
Entertainment – watch movies, play games or listen to music
-
