Izizathu ezimbalwa ezenza zingasebenzi ku-computer

Man, kwavele ukuthi wayeka ikhibhodi ukusebenza kukhompyutha, bambalwa kakhulu abantu ngabe umona. Futhi, njengoba ngokuvamile kwenzeka, izinkathazo ezinjalo ngokuvamile kakhulu kwenzeke ngesikhathi lapho "evutha" imibiko umaluju, kwenziwe iqoqo iziqu iphrojekthi, ngesikhathi impi ngoba isiphetho izwe ezilandelayo isiqophi game, nokunye. Ngakolunye uhlangothi, umbuzo othi "Kungani ikhibhodi kukhompyutha yakho" kusethelwe hhayi kaningi kakhulu, kusukela ekuqaleni "Inkathi USB" abaningi "izifo ebuntwaneni" emkhakheni Computing amadivayisi esikhathini esidlule. Ngokwalokhu esesixoxe ngakho ukwehluleka ikhibhodi - ithuba uhlobo ukuziqhenya "inhlanhla" yakhe.

uxhumano

Zonke ikhibhodi yesimanje ukuxhuma kwi-umbadlana usebenzisa USB ibhasi serial esibonakalayo. Ngaphambi prodution ejwayelekile PS \ 2, it has eziningi eziwusizo, phakathi okuyinto singaqokomisa kungenzeka "ashisayo-eguqulayo". Lokho, umsebenzisi kwakuthiwa lapho iyunithi uhlelo ukuxhuma nokunqamula kumaphoyinti okufinyelela e-plug -USB ku- slot ezifanele iyatholakala. Futhi abaningi ukuyisebenzisa, ikakhulukazi abanikazi amakhompyutha ephathekayo. Kulokhu, torque ezimbili ezimbi. Okokuqala, kwaphawuleka ukuthi njalo kudivayisi usuke kuholela yokuthi oxhumana entwasahlobo-Kulayishwa i-plug ukuze kuyaqina, okuholela ukusebenza okhathazekile (ugesi ubalekela noma umugqa idatha). Akumangalisi lokhu ilandelwa umbuzo othi, "kungani akusebenzi ku nge-computer." Ngakho, lapho yokuxhuma i-plug njalo azigugi zidinga ukushintshwa. Okwesibili, ngezinye izikhathi ehluleka, ngakho lokhu akufanele kube ukuthi kungenzeka ukuba kabi ashisayo kudivayisi esikhundleni. Ukuze uhlole oxhumene nabo kudingeka uvale i-computer, unqamule isixhumi ikhibhodi bese uxhuma futhi ngokucophelela, ngobumnene, nekuthiwa kwenzelwa ukweseka embobeni. Ngezinye izikhathi kungenzeka ukubuyisela oxhumana inaliti kusimo sangaphambilini entwasahlobo-ukulayishwa.

izinkinga zikagesi

Njenganoma iyiphi enye idivayisi ye-USB, ikhibhodi kunikwe amandla ngokuqondile port. Futhi njengoba izici sangekhatsi imbande kangangokuthi omunye chip axhunyiwe ukulawula nezixhumi eziningana ngqo, khona-ke uma idivayisi ephezulu amandla (nge lwamanje 500 MA), ukusebenza kwabo ayiqinisekile. Isixazululo ilula: uma kukhona umbuzo ka "kungani akusebenzi on ikhibhodi computer" ke kuzomele ukhubaze wonke amadivayisi we-USB ngaphandle ezibaluleke kakhulu, futhi uhlole ukusebenza. Nge inqwaba kanyekanye USB okuphathelene nomngcele kudingeke usebenzise ihabhu Lesisemkhatsini nge njengomthombo wangaphandle. Futhi, kaningi kunenkinga nge-USB amakhompyutha ubudala kanye laptops, amandla kagesi, kanye nezinye izinto abaselona usizo kanye ukuvelela zokucindezeleka. Isinqumo efanayo yalezi. Futhi-ke, ungakhohlwa ukuthi inkinga ingase ibe ku isixhumi: ukuhlola, kufanele uxhume i-plug ibe ezahlukene USB port.

isofthiwe Fault

wokusebenza Modern ukuze uxhumane ikhibhodi usebenzisa umshayeli uhlelo lokulawula. Ngezinye izikhathi wayebamba ziyeke ukusebenza. Ngenxa yalokho, umsebenzisi akakwazi ukubona kungani ungazami ukuba nge-computer. Kufanele usebenzise i-mouse ukuya "Isiphathi sedivayisi" bese uzama ukuvuselela umshayeli e "amakhibhodi". Uma kungasebenzi, kubalulekile ukuba ukhiphe idivayisi, susa umshayeli umyalo ezifanele bese uxhuma ikhibhodi computer - kufanele kuvuse indlela Plug & Play.

izilungiselelo Casus

Ngo motherboards yesimanje BIOS has a isigatshana elikuvumela ukuba senqabe ukusetshenziswa kwesitoreji, ngokubeka Khubaza imodi. Uma ngasizathu simbe lokhu kwenzeka, kudingeke ukuba uthole PS / 2 ikhibhodi ubudala, uyisebenzisa ukuya BIOS (Del ukhiye ngokushesha ngemva kwamandla) nokuvumela-USB. Enye - ukuze usethe kabusha ukuze isimo sokuqala ngokuvala uhlelo elihambisana Sula CMOS jumper phezu umbadlana (indawo yayo ngqo kukhonjisiwe imiyalelo). Kufika ngezinye izikhathi sibhekene yokuthi ikhibhodi okungahambi kahle. Lokhu kungase kubangelwe ngephutha inkinobho NumLock ukuphokophela ukushintshela izindlela kwesokudla iyunithi digital. Uma ukukhanya self-osesikhundleni ivuliwe, udinga ngokucindezela izinkinobho zayo ukuze ushintshele komunye umbuso.
