Sei kombiyuta mbeva

Mumwe zvinokosha zvinoumba chero ano yekombiyuta - kombiyuta mbeva. Izvi "rodent" vagara chikamu kwete chete desktops asiwo Laptops, kunyange mune zvishoma dzakachinjwa muchimiro.

Sokunge kombiyuta mbeva, vose anoziva. Mune dzimwe nzira, chaizvoizvo zvinoita seboka rinozivikanwa chipembenene, kunyange navamwe ndishushikane. Zvinofungidzirwa kuti vaizotevera vanoshandisa kushamwaridzana ichi hachisi pachena. Kunyange zvazvo, kana chete nokuti ano kombiyuta mbeva kuwedzera akaita Wireless, kunyimwa "muswe".

Nheyo nokushanda mudziyo uyu zvikuru kushamisa nyore: kana vakatamira pamusoro pemvura hama Coordonatele vari chakasvitswa kombiyuta, apo Software akakosha dzikwanise cursor kufamba pamadziro Pointer. Chii kunakidza, zvingasava chete kuva zvavaisiita museve yacho uchishandisa hurongwa, asiwo hunhu mune mutambo kombiyuta. Zvinokonzera pachena nyore rinomuvanza basa mainjiniya, zvemagetsi mainjiniya uye programmers. Zvichienderana STRUCTURAL zviri kombiyuta mbeva vangava zvakasiyana remazita kufamba. Ngatiyeukei chii musiyano pakati izvi zvinoita mungashandisa namano.

The muenzaniso wokutanga akazviratidza makore 50 apfuura, paiva zvokuimba. Inside mudziyo ndiyo hombe chesimbi bhora zvinenge zvakazara paiva rabha. The repasi divi, akasvika neVadzidzi yokunze pamusoro, uye vamwe vaviri - pamwe rollers. Vaikwanisa kunge ina, asi vaviri chete ndivo kupatsanurwa. Kana iwe kufambisa ruoko rwakabata negonzo bhora tikaisa mabhanzi ndangobva kwavari - the chinja, uye ipapo yakashandurwa kuva kutevedzana kwezviitiko zviratidzo zvemagetsi vanotumwa kuti kombiyuta. rollers maviri kwakakwanira pakugamuchira rinoronga pfungwa mundege. Zvazvakashatira ichi mhinduro zvinosanganisira kudiwa nguva nenguva rokuchenesa bhora nokuomerera tsvina (mhepo bvudzi vachinamatira guruva) uye yaitsiva Worn zvinoriumba.

Nokukurumidza vakatsiviwa Manyiminya-zvemaziso mhinduro. Nechokunze, zvose anoramba kuzochinja, asi haizoshandisi vave chabviswa, chikatsiviwa yakawanda nesimba mhinduro - optocoupler. Nokuti zita "vanotyisa" akavanda zvikuru chisingakuvadzi akatungamirira uye Manyiminya Switch, vainziwo kunzi opto nemudzimai. Mumwe chinotenderera yakabatanidzwa pamwe Perforated vhiri yakaronga pakati Switch uye diode. Kana kutenderera danda chidzivaidzo rukova kuti yakanyorwa Switch uye chakasvitswa nekombiyuta. Kuziva kakawanda kusuduruka "hwindo / rusvingo", zvaigoneka kuziva kumhanya uye mirayiridzo kufamba.

Muna 1999, kwaiva yepakutanga kombiyuta mbeva, inonzi Manyiminya, apo zvokuimba nzira kurekodha rwokufamba akakwanisa chose kurega. Akatungamirira rinovheneka pemvura pasi negonzo, uye chinyakare kamera nevamwe kakawanda kunoita mifananidzo. The processor chikwata rinopindura navo pahwaro migumisiro anogumisa kuti velocity uye achitungamirirwa misha. Tinogona chete uchatamisa date mutyairi chirongwa.

Nokukurumidza vakatsiviwa Laser nadzurudzo. The processor kwazova zvibereko, pfungwa yakarurama rwakawedzera, "matambudziko" hukawanika apo Switch zvikasashanda, iri dzotsauka. Musiyano mukuru nevamwe Manyiminya mhando akatungamirira, izvo inongorira chisingaoneki, uye michini. Nenzira, kupfuura zvinodhura kombiyuta mbeva - ndiko Laser. Zvisinei, ayo kudhura (vanopfuura zviuru 24 zvamadhora) wakakodzera kunyanya inlaid dombo rinokosha, kwete rwokugadzira zvinhu.
