1.2.2 Applications Generation

• Software that performs tasks for a user [1] • requires system software to run

• low level software that provides a platform for application software to run • Operating systems and utility software are a type of system software

• word processor • Database management software • web browser • email client • spreadsheet software • presentation software • antivirus software • video editing software • IDE • virtualisation software • graphics manipulation

• for creating/editing/printing text documents • eg Microsoft word, Google docs

• for storing/querying/managing/retrieving data • eg MySQL. Oracle

• for browsing the web and accessing info online • to view websites eg. To purchase • eg. Google chrome, Firefox

physically reorganises files on a harddisk (HDD) so that they can be found and accessed faster [1]

• reduces file size to consume less storage space or for faster download over the internet

Detects and removes potential threats like viruses and malware [1]

Encodes file before transfer allowing users to send files over networks securely

The raw programming code written by a software developer to create an application

• Is where the original source code is made freely available and may be redistributed and modified [1] • this means that anyone can view, modify and access the source code [1]

• is free and customisable by the user [1] • source code can be amended by anyone and sold on [1] • the program can be tailored to specific needs [1]

• may have compatibility issues and many contain bugs • might be less user friendly

• the software is distributed as executable Machine code [1] • so source code is hidden/ not freely available [1] • there are licensing conditions restricting the redistribution/ there is no permission to amend the code [1]
