Systems software that provides other useful functions for operating the computer or performing computer-related tasks such as anti-virus programs
Systems software modules that perform frequently required tasks. They can be built into or called from other programs
System software that translates high-level programming languages into machine code. Includes compilers and interpreters. (An assembler translates low-level assembly code into machine code.)
One of the main functions of the operating system - allocating space in main memory to all currently running programs and their associated data, and recycling the space when they have finished
A device (hardware) that is connected to the CPU to provide input, output or storage
One of the main functions of the operating system - managing the input to and the output from the CPU
One of the main functions of the operating system - managing how several tasks or programs, which are all running at the same time, share the processor.
One of the main functions of the operating system - protecting the computer system from various hazards such as unauthorised users, viruses, hackers and accidental damage.
The method of communication between the computer and its user. Sometimes called HCI (Human-Computer Interface) or MMI (Man-Machine Interface).
Human-Computer Interface: another term for user interface.
Man-Machine Interface: another term for user interface
Graphical User Interface. A style of user interface, which is based on icons rather than text.
Stands for: Windows, Icons, Menus and Pointers. It describes a type of user interface where the user selects icons and menu items with a pointer of some kind (with a mouse, stylus or finger).
A style of user interface that is only text-based. Commands are typed in at a text prompt
A numerical reference to a location in memory.
A program that is running in main memory.
A program that is installed on a computer without your knowledge or permission with the purpose of doing harm. It includes instructions to replicate automatically on a computer and between computers.
A utility program that prevents harmful programs being installed and important files being changed. The antivirus software scans all the files
on the computer periodically and if a virus does install itself, it detects and removes it.
A utility program that prevents unauthorised access to computers or a LAN from the Internet and controls what sites computers on the LAN can access
A program that secretly records the user's actions on the computer including passwords and personal details they type when accessing a secure site.
A utility program that optimises the use of the hard disk space by collecting together the separate segments of each file into contiguous blocks (i.e. blocks next to each other) on the disk as well as grouping together the blocks of free space so newly saved files do not have to be fragmented (split up)
A utility program that deletes unnecessary files and settings to optimise the computer's performance
A utility program that, for any software already installed on the computer, will regularly check on the Internet for newer versions and updates, then download and install them
System Information and Diagnosis
A utility program that presents information about the computer hardware and usage as well as information to help diagnose problems
A utility program that formats secondary storage devices such as hard disks, preparing them for use.
File Transfer and File Management
A utility program that allows the user to create a logical view of
how their files are organised using folders. Allows the user to move files and folders, copy, paste, name and delete files and folders
Software that is supplied with its source code. The source code can be modified and the software redistributed (as long as this too is open source)
