Ib suam ntawm kev khiav hauj lwm systems

Hauv paus ntawm PC software - lub operating system, uas yog ib tug txheej ntawm cov kev pab thiab system software Cheebtsam uas muab tib neeg lub computer sis thiab tua ntawm lwm cov kev pab. Nyob rau hauv ib tes, nws yog zoo txuas nrog qhov yooj yim computer software, muaj nyob rau hauv lub BIOS, tab sis nws ua raws li ib tug them nyiaj yug rau cov kev pab cuam ntawm qib siab dua - daim ntawv thov, raws li tau zoo raws li feem ntau ntawm cov ntaub ntawv sau npe. Yuav kom koj khiav lag luam hauv lub computer ua raws li ib tug prerequisite rau hauv lub xub ntiag ntawm lub operating system rau lub hard disk. Thaum tus ntaus ntawv yog nyeem los ntawm cov hard disk thiab sau ntawv mus rau lub RAM, txoj kev no yog hu ua daus. Vim lub fact tias tam sim no muaj ntau ntau yam sib txawv systems tswj daws meej thiab ntau cov hom phiaj, nws yog ib yam uas muaj ib tug kev faib ntawm kev khiav hauj lwm systems. Cia peb, nyob rau hauv sau ua ke rau daim ntawv.

Ib suam ntawm kev khiav hauj lwm systems nyob rau cov kev siv ntawm cov tswj algorithms siv thiab computer kev pab. Nyob rau hauv lub processor tswj algorithm yuav subdivided operating systems rau ib leeg-tasking thiab multi-tasking, multi-processor thiab ib-processor, ib leeg-neeg siv thiab multi-neeg siv, network thiab lub zos.

Ib suam ntawm kev khiav hauj lwm systems nyob rau hauv lub xov tooj ntawm kev pab raws qib khiav ib txhij: ib-tasking thiab multi-tasking. Ib leeg-tasking system siv ib cov ntaub ntawv txhais tau tias kev tswj, cov kev tswj ntawm peripheral pab kiag li lawm, thiab interconnection txhais tau tias, thiab nrog cov neeg siv. Rau multi-tasking tshuab tsiag ntawv los ntawm kev siv ntawm cov tib cov cuab yeej raws li rau ib leeg-neeg ua hauj lwm, tab sis nyob rau tib lub sij hawm lawv khiav lub division, qhia cov kev pab: nco, processor, peripherals thiab cov ntaub ntawv.

Hom ntawm kev khiav hauj lwm systems nyob rau hauv qhov chaw ntawm siv multitasking: cov ntaub ntawv ua nyob rau hauv batch hom, real-time systems thiab lub sij hawm sib faib. Lub hom phiaj tseem ceeb ntawm batch khiav tshuab yog cov paub tab uas tsis yuav tsum tau ceev ceev tau. Lawv lub ntsiab lub hom phiaj yog yuav kom daws qhov loj tshaj plaws pes tsawg tus ntawm cov paub tab ib chav tsev lub sij hawm los yog lub siab tshaj plaws bandwidth. Tej systems cia mus cuag kev kawm ntawv siab nyob rau hauv kev soj ntsuam txog nrog loj nyiaj ntawm cov teeb meem, tab sis lawv txo tau cov efficiency ntawm tus neeg siv nyob rau hauv kev sib tham sib hom. Timesharing system emits ib tug me me lub sij hawm ncua rau txhua tus neeg ua hauj lwm, thiaj li tsis muaj ib tug ua hauj lwm rau ib tug ntev lub sij hawm tsis tau lub processor. Nrog ib tug tsawg kawg nkaus xaiv lub sij hawm yuav ua tau ib lub tsos ntawm simultaneous tua ntawm ib tug xov tooj ntawm cov teeb meem. Los ntawm txos bandwidth, xws tshuab tso cai rau cov neeg siv yuav ua hauj lwm zoo heev nyob rau hauv kev sib tham sib hom. tiag tiag-lub sij hawm kev tswj systems siv rau kev yam khoom los yog cov txheej txheem.

Ib suam ntawm kev khiav hauj lwm systems nyob rau hauv lub xov tooj ntawm txhawb cov neeg siv: ntau thiab ib leeg-neeg uas ua ntawv. Nyob rau hauv multiplayer, txhua tus neeg muaj lub peev xwm los customize rau koj tus kheej system interface, piv txwv li lawv muaj lub sij hawm los tsim koj tus kheej cov kev cai ntawv, tus kheej xim tswvyim thiab thiaj li nyob. Nyob rau hauv xws systems, muaj txhais tau tias kev tiv thaiv ntaub ntawv los ntawm lub kev nkag tau ntawm lwm cov neeg.

Cov muaj nyob rau hauv lub system txhais tau tias ib tug multiprocessor cov lus yog ib qho tseem ceeb cov yam ntxwv, xws muaj qhia nyob rau hauv Net tais, OS / 2, Widows NT.

Txij li thaum peb yog accustomed mus siv lub qhov rais system, ces koj yuav txhawj txog yog nws cais. Yog li, lub ntsiab lub qhov rais kev khiav hauj lwm systems, uas tau raug siv muaj rau tib yam cov neeg siv, lub qhov rais 95, 98, NT, XP, Xya.
