Khoos phis tawj


ROM BIOS firmware rau ntawm ib tus menyuam hauv motherboard

Hauv qee yam, qhov ntau yam ntawm cov khoom ntim yog ib qho tseem ceeb raws li kev khiav haujlwm hauv lub computer ua haujlwm. Txawm li cas los, tsis zoo li feem ntau cov kev khiav hauj lwm niaj hnub, firmware tsis tshua muaj ib qho zoo-evolved automatic mechanism ntawm muab kho dua nws tus kheej kom txhim kho tej teeb meem kev ua haujlwm tom qab xaib tsev.


Tus BIOS yuav yog "manually" tshiab los ntawm tus neeg siv, siv ib qho kev pabcuam me me. Hauv kev sib piv, firmware nyob rau hauv cov khoom siv (harddisks, DVD drives, flash cia) tsis tshua tau kho tshiab, txawm tias thaum flash (es tsis yog ROM) cia siv rau qhov firmware; tsis muaj cov tswv yim tsim kev lag luam los txhim kho lossis kho cov ntawv kho mob.


Feem ntau cov khoos phis tawj lawv lub computer tshwj xeeb. Cov khoom siv xws li tshuab luam ntawv, luam yeeb, koob yees duab thiab USB flash drives muaj nyob hauv tsev khaws ntaub ntawv; qee cov cuab yeej tseem tuaj yeem tso cai ua kom tiav ntawm lawv tus firmware.


Muaj qee tus nqi pheej yig tsis muaj qhov cim xeeb uas tsis muaj qhov cim tseg rau qhov firmware, thiab tsuas tso siab rau tus tswv tsev kaw neeg los hloov cov kev pabcuam hauv kev ntaus ntawv los ntawm CD lossis CD.


Khoom siv

Raws li ntawm 2010, feem ntau cov suab paj nruag ntaus suab paj nruag hloov khoom dua tshiab. Qee cov tuam txhab siv cov software tshiab los ntxiv cov playable file formats tshiab (codecs); Iriver ntxiv Vorbis playback txhawb li no, piv txwv li. Lwm cov nta uas yuav hloov nrog firmware tshiab xws li GUI los yog lub roj teeb lub neej.

Tsheb

Txij xyoo 1996, feem ntau cov tsheb tau ua haujlwm hauv computer thiab ntau lub tshuab ua kom pom tias muaj teeb meem rau qhov teeb meem. Raws li xyoo 2010, cov tsheb niaj hnub no kuj ntiav cov khoom siv tiv thaiv kev tiv thaiv kev tiv thaiv siv computer (anti-lock braking systems (ABS) thiab lub computer-tswj kev tiv thaiv units (TCUs). Tus tsav tsheb kuj tuaj yeem tau txais cov ntaub ntawv hauv kev khiav hauj lwm thaum tsav tsheb zoo li no, xws li cov sij hawm siv roj hluav taws xob thiab cov kev nyeem siab ntawm lub tsheb ceev. Cov tswv lag luam hauv zos tuaj yeem hloov cov tsheb tuam ntau dua.
