Discuss the following types of operating systems.- Multi tasking- Multi processing- Multi substance ab accustomr- Real time(12 marks)1. 3 functions of operating systems be as followa) Manage the computer resources such as central processing unit,memory, magnetic disc drives and printer. In other words it acts like atranslator which allows the covering software to communicate withthe computer hardware.b) Caretaker which making sure that date is deliver in the right place,programs are loaded into memory properly and that the computersfile system is all kept in order.c) Execute and provide function for applications software in otherwords as system tools (programs) apply to monitor computer performance,debug problems, or maintain parts of the system. A set of libraries orfunctions which programs may use to perform specific tasks curiouslyrelating to interfacing with computer system components.2. 3 factors affecting the choice of an operating system are asfollowa) Choice of processor and hardware for guinea pig if server machine is aSun computer then provide be forced to use Solaris which is Suns versionof UNIX.b) A hardware or software protocol, contained in the electronics ofthe disk controller and disk drive, that manages the exchange of selective informationbetween the drive and computer. The most common interfaces for smallcomputer systems are AT (IDE) and SCSI.c) Compatibility of computer networks types including LANs and WANs,for example UNIX and Window NT are usually use to become the mainframeof WANs networking system.3.a)Multi tasking - In a multitasking operating system where threefoldprogra ms can be running at the same time, the operating systemdetermines which applications should run in what order and how muchtime should be allowed for each application before giving anotherapplication a turn. Examples of multi tasking operating system areUNIX and Window 2000.b)Multi processing - An operating system adequate to(p) of supporting andutilizing more than one computer processor for example Linux, UNIX,Windows 2000.c)Multi substance abuser - A multi user operating system allows for multiple users
