Ikhibhodi yomdlali

Igundane nekhibhodi amathuluzi amabili abaluleke kakhulu akuvumela ukuthi uxhumane ne-PC yakho. Izinga nomsebenzi wabo uyahlukahluka kuye ngenjongo - isibonelo, amakhibhodi ebhajethi anezinketho eziyisisekelo kuphela avame ukutholakala endaweni yehhovisi. Kodwa-ke, abadlali badinga okwengeziwe - kokubili ngokuya ngokusebenza kanye nobunjiniyela.

Ukunikezwa okuhlukahlukene okuvela kubakhiqizi bamakhibhodi kubadlali bazokwanelisa bobabili abathandi bezinto ezinhle ngendlela yamaphaneli e-LCD engeziwe noma ukukhanya kwe-backlight okuyinkimbinkimbi, kanye nabantu abafuna izixazululo ezilula ezizosebenza kunoma yimuphi umdlalo.

Iyiphi indlela okufanele ikhibhodi ibe nayo?

Kunezinhlobo eziningana zamakhibhodi emakethe ezihlukile ngomklamo. Lawa alandelayo:

• Mechanical - endala futhi esadumile emakethe. Isenzo saso sisekelwe ekusebenzisaneni kwezakhiwo zemishini. Ngaphansi kokhiye ngamunye kukhona inkinobho, umsebenzi wawo ukurekhoda ukunyakaza nokudlulisa ulwazi oluhambisanayo kukhompyutha.

• Tangential, ihlukaniswe yaba izigatshana ezintathu. Njengoba igama lisho, ulwazi ludluliselwa kukhompyutha njengomphumela wokuxhumana phakathi kwezakhi ezimbili zekhibhodi. Lezi zigaba ezincane yilezi: ulwelwesi (onolwelwesi olukhethekile oluhlukanisa amasistimu kagesi kuze kucindezelwe ukhiye), olubuswayo (kulokhu, lapho ucindezelwa, idome eliqukethe okuthiwa yi-carbon contact flexes) nokuba nenjoloba eqhubayo, okuthi, lapho icindezelwa ngokhiye, epuletini elinezixhumi zikagesi.

• Abangeyena othintana naye - ngokusho kwe-nomenclature, isenzo saso asisekelwe ekuthintaneni ngokomzimba kwezakhi zesakhiwo, kodwa esenzweni esingathinteki sama-capacitors noma ama-optocouplers.

Ikhibhodi yomdlali ngokuvamile yenziwa kusetshenziswa ubuchwepheshe bokuxhumana: ikakhulukazi i-dome-scissor, okuyinguqulo ethuthukisiwe yesigaba esingaphansi solwelwesi. Lezi yizixazululo ezithandwayo ezonga ukukhiqiza futhi ngesikhathi esifanayo zinikeza impilo yesevisi eyanelisayo. Enye indlela enhle kulezi zinketho ikhibhodi yokudlala yemishini, ejabulela isimo sehlelo emibuthanweni yobungcweti. Ngaphambi kokuthenga, kufanelekile ukucabangela lezi zinhlobonhlobo ngokuningiliziwe ngokusebenza kwazo phakathi nomdlalo.

Izinhlobonhlobo ze-scissor-dome. ukuhamba kwesabelomali

I-membrane yekhibhodi yesikelo icindezelwa endaweni yokuxhumana ngeleva yesikere sepulasitiki. Lokhu kuqinisekiswa ngokuyinhloko ngephrofayili ephansi yezikhiye kanye nokufushane okubizwa ngokuthi ukushaywa kokhiye, okungukuthi, ibanga okumele ukhiye ulihambe kusukela ngesikhathi ucindezelwa kuze kufike lapho kuxhunywana khona. Ngenxa yalesi sizathu, le membrane ivame ukusetshenziswa kumadivayisi aphathwayo namakhibhodi amancane. Iphinde ibonakale nempilo ende yesevisi (kufika ku-20 million ukuchofoza).

Ukushintsha kwe-Dome kunikeza ukusabela okukhulu (ukunemba kwesikhathi nokusebenza kahle kokuchofoza ukhiye) nokuqina okufanayo (ngokuvamile ukuchofoza okuyizigidi ezingu-10 kuya kwezingu-20), abalandeli bemidlalo eshesha kakhulu nesebenzisa i-hardware abayoyijabulela.

Ikhibhodi yomshini. Intengo ephezulu kanye nayo ikhwalithi engcono

Lolu hlobo lokwakha alulona neze olushibhile, kodwa lusavame ukubhekwa njengolufanelekela kakhulu izidingo zokudlala. Amasampula okuqala ezakhiwo ezinjalo (ezakhiwe ekuqaleni kwawo-70s) ayebonakala ngempilo yesevisi efinyelela emashumini ambalwa ezigidi zokuchofoza.

Umehluko omkhulu phakathi kwesixazululo esidingidwayo kanye nalesi esichazwe ngenhla sisengqikithini yomshini, kulokhu okusekelwe emithonjeni elula, yendabuko. Nakuba ama-switch mechanical anama-domes, indima yawo kuphela ukwenza kusebenze ukuthunyelwa kwesignali kukhompuyutha. Intwasahlobo inesibopho "sokuzizwa" kokhiye, ukuhlinzeka ngokhiye omkhulu wokuhamba, umsindo wokuchofoza okujabulisayo kanye nesici esiphezulu sokuqina.

Inkampani enelungelo lobunikazi bekhibhodi yomshini isasebenza emakethe. I-Cherry, ngoba sikhuluma ngayo, ikhiqizwa ngezinhlobo eziningana. Edume kakhulu phakathi kwabadlali iCherry MX, efika ngezinhlobo ezine (ezimnyama, ezinsundu, ezibomvu neziluhlaza okwesibhakabhaka) ezihlukene, okuhlanganisa ukugxuma, impendulo, kanye nokucindezela okufanele kusetshenziswe ukuze kusebenze.

Ama-Cherry MXs ngokuvamile akwazi ukuchofoza amashumi ezigidi, okuwenza abe amadivayisi anezikhathi ezinde kakhulu. Lokhu kuqinisekiswe ukubuyekezwa nokuhlolwa okuningi. Ihlanganisa amandla okhiye aphansi, ivolumu emaphakathi uma isetshenziswa, kanye nempendulo egculisayo enempilo enkulu yezigidi ezingamashumi ayisishiyagalombili zokushaya ukhiye ngokhiye ngamunye.

Oomakhenikha akuyona yonke into. Ezinye izici zamakhibhodi amageyimu

Imininingwane eyanele yokuklama. Nakuba izindlela zisenhliziyweni yokuthi amakhibhodi asebenza kanjani, asikwazi ukusiza kodwa siqaphele ezinye izici ezinomthelela obalulekile ekusetshenzisweni kwansuku zonke. Lokhu kufaka phakathi, phakathi kokunye:

• Inhlangano yezihluthulelo - indawo yazo, ubukhulu kanye nokukala. Amamodeli ekhibhodi athile ahlukile kwamanye ngosayizi wezinkinobho zomsebenzi, kanye nokuma kwezinye izinkinobho (ikakhulukazi Enter noma Shift). Kuyafaneleka ukukhetha ihadiwe enesakhiwo esifaneleka ngangokunokwenzeka kokhiye abavame ukusetshenziswa kakhulu emidlalweni - ngokwesibonelo, i-shift encane engakwesokunxele ngeke yenze kube lula ukugijima ku-FPS.

• Umumo, umumo, ubude bokhiye, nokuthayipha - lezi zinketho zithonywa ngokwengxenye ukuklama kwamaswishi (isibonelo, amakhibhodi esikele azohlala enokhiye wohambo oluningi kunemishini). Abanye abakhiqizi banikeza izinkinobho zombili ezigoqeke kancane futhi ezinobuso obuyisicaba. Indlela yokunyathelisa nayo ibalulekile (kunezindlela eziningana zalokhu: kusukela eshibhile, okungukuthi ukuphrinta kwephedi, kuya ekukhiqizeni kakhulu futhi ebiza kakhulu, okufana nalokho okubizwa ngokuthi i-sublimation).

• Izici ezengeziwe ngendlela yokuphumula kwesandla okunamathiselwe, ukulungiswa kobude noma izinketho zokukhanyisa. Lezi zici azizona ingqikithi yokusebenza, kodwa ngokuqinisekile zithuthukisa ukunethezeka kokusetshenziswa futhi zithuthukisa inani lobuhle.

Ngakho-ke, lapho ukhetha ikhibhodi yokudlala, kufanele unake amaphuzu amathathu ayinhloko: uhlobo lomshini, umsebenzi kanye nokusebenza okwengeziwe. Indawo yokuqala, njengokukhethwa kwanoma yimuphi omunye umshini, kufanele kube izidingo zomuntu ngamunye, ezingahlangatshezwana kalula ngokusizakala ngokunikeza kwethu. Ngomdlalo we-retro, isibonisi se-LCD esengeziwe ohlangothini lwekhibhodi ngeke sibe nalusizo, okungase sibe usizo olubaluleke kakhulu lapho ubamba izihloko zakamuva ze-AAA.
