Operating system (continued)
there have been many operating systems designed and made over the years, when an operating system is being made it is normally made for a certain type of computer, as an example; mac had an operating system made called mac os this runs on macs.
for peoples personal computers there are two mainly used operating systems, windows and linux.
unix is an operating system created for mainframe computers (mainframe computers are used by large organisations and companies, also colleges and universities).
finally for mobile phones the operating systems are fairly different to computer operating systems , symbia, android and ios are all operating systems for mobile phones.
all of these operating systems are different but they are all similar as well. the operating systems are all created fr certain computers or devices but they all provide a gui (graphic user interface), they manage the computer’s/device’s memory and manage the hardware. in the past it was very difficult and complicated to do what we call “simple” tasks now. previously it was managed using a system called MS-DOS, with this system the user would have to look through lots of information to do what was needed where as now we have windows and mac (and more) that make it alot easier to copy, drag, paste, move and manage information and documents on a computer. the files have now been changed to an easier way of management where as it was all lists of writing and information now it has been changed to a file you can actually view and you can view the file and information easier (there is a visual aid)
this is MS-DOS and below is windows just to show you just how different file management is now.
There are four different types of operating systems.
in total there are four different types of operating systems based on the types of computer that they are in control of and that of which they sort the applications. listed below they are;
Real-time operating system (RTOS)-
Real-time operating systems are used in machinery, scientific instruments and industrial systems, the user actually has very little control or no control as this type of operating system is made to run these machines or instruments almost entirely they are used to run one process or machine. as an example in a sikorski s-92 helicopter the the real-time operating system runs the multi function display system.
Single-user, Single task -
this system was designed so that the user can do one task efficiently at a time.
Single-user multi-tasking-
this is the type of operating system that people use at home on there laptops and personal computers
