Kungani ikhibhodi

Ngaphandle igundane nekhibhodi akunakwenzeka ukusebenzisa ngokugcwele kukhompyutha. Thinta izikrini ngabaqaphi ukuba nesenzakalo mass zazo silungiselela uhlelo lwayo lokusebenza elisha, i-Microsoft namanje prohibitively ezibizayo. Ngakho manje main interface yomsebenzisi nokuxhumana nge-computer amadivaysi amabili. Software Onjiniyela ozama landulele ezimweni ezihlukahlukene, kuhlanganise imikhiqizo yabo bangasebenza ingalo eyodwa kuphela noma ikhibhodi eyodwa. Lezi zixazululo ukwenza umsebenzi, kodwa kube lula ukusetshenziswa ayikwazi kubhekwe.

Uma ungasebenzi ikhibhodi kanye igundane, ke lifana inhlekelele. Ngenxa yokwethuka kusekelwa imicabango engemihle, "ulondoloze imali ukuthenga," "Ukulungiswa kuyofika imali eningi," nokunye Okokuqala, udinga ukuthatha wena esandleni futhi ngokucophelela ukuhlola isimo. Kwanele ukuthi computer uqobo sivuliwe, ngakho-ke, izindleko zezimali, uma bedinga , uzoba mncane. Eqinisweni, ngokuqondene nezizathu eziye zenza zingasebenzi ikhibhodi, abaningi.

Mhlawumbe abanye zifiki ngeke kukumangaze ukwazi ukuthi ikhibhodi computer ngokweqile akusona nje base noplastiki izinkinobho entwasahlobo-ukulayishwa (ikhibhodi), kanye nedivayisi ephelele microcontroller lalo. Hlaziya ke, ungabona ngaphakathi chip, futhi izakhi eziningana ezihlobene electronic - lena isilawuli noma, uma uthanda, microprocessor ezikhethekile. Ilandisa ukucindezela inkinobho futhi ithumela ulwazi kubo ngokusebenzisa imbobo kule uhlelo ibhasi computer, bese - ku isicelo.

Ngakho, nanka, le izizathu okungenzeka yizimbangela ikhibhodi akusebenzi: Fault ikhibhodi microcontroller, wire eliphukile noma isixhumi, ukwehluleka port kwikhompyutha, ukwehluleka kohlelo. Kungakhathaliseki ukuthi sasiyini isizathu, umsebenzisi angakwazi kuphela ukulungiswa nge inkinga wire. Kuzo zonke ezinye izimo zidinga izixazululo ezinqala more. Umgomo we operation igundane computer futhi efanayo: it has microcontroller lalo.

ikhibhodi zokugwema ukuphuka kungaba ezimbili zama: ikhibhodi akusebenzi uma ukuqala uhlelo lokusebenza kanye izicelo. Uhlelo lokusebenza isebenzisa ukulawula ikhibhodi umshayeli walo (izinhlelo ezikhethekile), ngakho-ke uma omunye wabo ehluleka, ngeke bakwazi kahle ukucubungula zimpawu kusuka microcontroller ikhibhodi. Isixazululo elula - ufaka ke. I-Windows abasebenzisi kudingeka silandele indlela "Computer - Properties - Manager Kudivayisi - keyboard" futhi ususe umshayeli. Ngemva kwalokho, uhlelo kuzodinga ukuqalisa kabusha. Ngezinye izikhathi kungase kusize ukufaka umshayeli kamakhi, isibonelo, Logitech.

Namanje iphutha kwande lapho umsebenzisi alazi ukuthi kungani ikhibhodi akusebenzi. Indlela elula enquma kokusebenza yayo - ukubona isimo LED capslock, NumLock futhi ScrollLock. Ngokushesha ngemva kokubuya kukhompyutha umzuzwana baya on and off - njengoba kufanele kube, ngalesi sikhathi, i-microcontroller sihamba isivivinyo futhi kuwuphawu impilo logic eziyisisekelo izifunda zabo.

Ezinye amakhompyutha ezindala ekuqaleni usethe ukusebenza ikhibhodi PS / 2 ejwayelekile, futhi ngokuzenzakalelayo, amadivayisi we-USB lokuxhasa zikhutshaziwe. Kulokhu, udinga ukuxhuma kwi-computer nge-PS / 2 ikhibhodi futhi ulungiselele zonke oyifunayo. Uma akukho okushintshile futhi ibingakazeki kungani ikhibhodi ayisebenzi, kufanele uxhume ku-computer ngokusebenzisa enye iphothi (isixhumi).

Kuyasiza ukuvala wonke amadivayisi axhunyiwe ku emachwebeni efanayo, ngoba ngezinye izikhathi ikhibhodi akuyona amandla anele kagesi. Ukuze ikhibhodi USB BIOS kudingeka ukuvimbela «EHCI Hand-off», wokusebenza entsha akudingeki-ke, futhi liphazamisane nomsebenzi evamile konke ehluleka mozhet.Esli, it is neshaya ukuxhuma ikhibhodi. Okusetshenzelwe - kusho ukwehluleka isizathu ikhibhodi kakhulu. Cha - inkinga isixhumi port noma nge isilawuli.
