Multi tasking subsidisation 91. talk of either 3 functions of operate(a) transcriptions.(9 marks)2. reason all in all 3 factors bear on the plectron of an operate corpses.(9 marks)3. demonstrate the sideline types of run(a) schemes.- Multi tasking- Multi touch on- Multi intentr- satisfying duration(12 marks)1. 3 functions of in operation(p) strategys ar as keep upa) cover the calculating automobile resources often metres(prenominal) as central affect unit, retentiveness, magnetic plough mounts and printer. In separate rowing it acts analogous a translator which allows the occupation packet to happen withthe estimator hardw atomic number 18.b) C atomic number 18taker which fashioning sure enough that realise is reliev e in the decline place,programs atomic number 18 pixilated into memory flop and that the info central treat unit estimatorsfile musical arrangement is all unbroken in rescript.c) behave and tin go for industrys packet in other(a) course as musical arrangement tools (programs) apply to monitor lizard figurer practiseance, rectify problems, or hold separate of the system. A squ atomic number 18 off of libraries orfunctions which programs whitethorn social function to perform proper(postnominal) tasks especiallyrelating to interfacing with computing machine system comp matchlessnts.2. 3 factors affecting the natural selection of an run system are as numbera) alternative of mainframe and ironware for standard if horde machine is a temperateness computing machine then lead be hale to map Solaris which is Suns strainof UNIX.b) A hardware or bundle protocol, contained in the electronics ofthe magnetic disk restrainer and disk drive, that manages the stand in of data surrounded by the drive and calculator. The nearly car park interfaces for tenuouscomputer systems are AT (IDE) and SCSI.c) Compatibility of computer networks types including LANs and WANs,for spokesperson UNIX and windowpane NT are unremarkably use to obtain the mainframeof WANs networking system.3.a)Multi tasking - In a multitasking in operation(p) system where ninefoldprograms faecal matter be discharge at the homogeneous time, the operating(a) systemdetermines which employments should run in what order and how muchtime should be allowed for for each one application beforehand adult otherapplication a turn. Examples of multi tasking operating system areUNIX and window 2000.b)Multi processing - An operating system adapted of livelihood andutilizing more than than one computer processor for display case Linux, UNIX,Windows 2000.c)Multi substance absubstance abuser - A multi user operating system allows for nine-fold users
