As media studies software and systems presentation

  1. 1. Systems and Software
  2. 2. Applications software  Application software allows users to perform useful tasks by being applied to a particular problem. Application software would not normally be applied to the management of the resources of the computer such as memory or time spent processing jobs.  Application software is used for a specific job and purpose or application ( hence the name) such as ordering, payroll, stock control, games, creating websites, image editing and so on. Continue
  3. 3. Operating System Graphical User Interface SYSTEMS SOFTWARE File Management BACK Utilities
  4. 4. Systems software  System Software controls the computer hardware and thus providing a platform for application software to do a useful task.  The majority of these programs are supplied by the manufacturer of a particular hardware component within your computer. However, some are supplied with the operating system such as “Windows explorer” which allows you to access files.  System software consists of four programmes: the operating system, Graphical User interface (or GUI), file management and utilities. BACK
  5. 5. Operating systems  The main purpose of an operating system is to allow the applications to interact with computer hardware, lets it behave in a predictable way so that the application software can use it.  The operating system performs specialist tasks vital to the functioning of the computer or other device with an operating system. These are: Diagnostic checks BACK Input/output management Memory/data management Security and other tasks
  6. 6. Diagnostic checks  This is when the operating system performs and initial check of the entire system when the computer is switched on (e.g. booted up).  These preliminary checks are very important for the safety and smooth running of the computer, as it shows any problems within the operating system. BACK
  7. 7. Input/output management  The operating system controls the receipt of inputted data from the input devices such as the keyboard, mouse or touch screen..  It also controls the output of information by sending it to the monitor and/or other output devices. BACK
  8. 8. Memory/Data management  The operating system also controls the memory and data aspects of the computer as well as the input and output processes.  It controls the memory allocated by programs, as multiple programs could be held in memory simultaneously.  It also controls the flow of data to and from the main processor, as well as working out where to store the data on the hard disk drive. BACK
  9. 9. Security and extra information  The operating system deals with security issues such as usernames and passwords.  It also handles the interrupts occur when an application software contains bugs or if there was a hardware fault.  Some of the current most popular operating systems include Windows, Macintosh os-x, UNIX and Linux. BACK
  10. 10. Utilities  A utility is a program that performs a very specific task and a series of utilities comes as part of the systems software.  Utilities are not widely regarded as applications because they are fairly simple and will only perform one very specific task, which is always related in some way to managing the computers main resources.  Examples of utilities include: File converters BACK Virus scanners
  11. 11. File Converters  File converters convert computer data inputted into a system from one format to the another.  Each computer program handles data in a different manner.  Whenever any one of these variable is changed, data must be converted in some way before it can be used by a different computer, operating system or program. BACK
  12. 12. Virus Scanners (Anti-Virus Software)  Antivirus or anti-virus software is software used to prevent, detect and remove malware such as: computer viruses, malicious BHOs, hijackers, ransom ware, key loggers, backdoors, rootkits, Trojan horses, worms, malicious LSPs, diallers, fraud tools, adware and spyware.  Computer security, including protection from social engineering techniques, is commonly offered in products and services of antivirus software companies, such as MacAfee and Norton security. BACK
  13. 13. File management  A file manager or file browser is a computer program that provides a user interface to work with file systems.  The most common operations performed on files or groups of files are: create, open, edit, view, print, play, rename, move, copy, delete and search/find.  More complex operations include the ability to modify file attributes, properties and file permissions. BACK
  14. 14. Graphical User Interfaces  A Graphical user interface (GUI) is a type of user interface that allows users to interact with electronic devices and files through graphical icons and visual indicators.  GUIs were produced to enable people with basic IT knowledge access the computers files and devices with ease, as learning how to use a command input interface was complicated and took time.  GUI’s are used by virtually everybody, with experience or not, and are used on virtually all of the operating systems around the globe (including mobile devices), including Mac OS and windows being the most popular.
