  • 4. What are the main functions of anoperating system?. The main function of the operating systems are Process management Memory management Device management Storage management User interface
  • 5. Process management This ensembles the planning and process of an activity It also monitors the performance of a process This sends the activity to the correct place which allows a more organised structure in your computer processes.
  • 6. Memory management This involves ways of moving portions of memory to programs at your request and then freeing it for free use when needed again.
  • 7. Device management This allows the user to view and control the hardware on our computers. When hardware is not working it is highlighted for the user to deal with themselves. The operating systems need a device driver because if not hardware could remain damaged if the user does not recognise it and if there wasnt one on we would not get as much control on our computers without one
  • 8. Storage management This is a data storage technique used between low-cost and high-cost storage media HSM systems exist because high-speed storage devices, such as hard disk drive arrays, are more expensive
  • 9. User interface The user interface is the space between us humans and the computers and technology we create. The aim of this is to allow smooth and complete control over the computer or machine with regular feedback from the machine. Graphical user interfaces accept input via devices such as computer keyboard and mouse and provide articulated graphical output on the computer monitor. Command line interfaces, where the user provides the input by typing a command string with the computer keyboard and the system provides output by printing text on the computer monitor.
