System iyunithi - Iyini? Izimpawu idivayisi iphinde uxhumano uhlelo iyunithi

Abasebenzisi abaningi abaqondi ukuthi kungani computer ngaphezulu wayebizwa ngokuthi iyunithi uhlelo. Lo mqondo eziyinkimbinkimbi futhi uyazifihla lahlukene imishini, okuzoxoxwa ngayo kulesi sihloko. Umfundi umenyiwe ukuze ufunde mayelana idivayisi ikhompyutha, izici amadivayisi bese uxhuma iyunithi uhlelo.

umqondo generalized

Abasebenzisi abaningi bakholelwa ukuthi metal icala computer futhi iyunithi uhlelo, okuyinto iyisonto izingxenye ezihlukahlukene obhekene nokusebenza. Lo mbono unephutha. Eqinisweni block uhlelo iyona element efanayo iprosesa, inkumbulo noma ikhadi. Zonke lezi zingxenye ikhompyutha ayadingeka ukuze yimuphi umsebenzisi.

Igama elithi "uhlelo iyunithi" ubafihlela okuthile ngaphezulu - iqoqo izingxenye ezihambisana nomunye futhi ukuqinisekisa operation esitebeleni of the okusebenza, izinhlelo kanye imidlalo. Futhi konke lokhu iqoqo amadivayisi kuyinto lonke futhi ephelele, umdayisi umkhiqizo. Kuyoba lula ukusho ukuthi iyunithi uhlelo - ikhompyutha siqu ngaphandle qapha, ikhibhodi nezinye okuphathelene nomngcele.

Ifomu Factor

Usayizi iyisici okuyisisekelo ukuthengwa yimuphi ubuchwepheshe bama-computer. Ngakho-ke, umfundi uyamenywa ukuba uqale isifundo futhi ifomu factor. Ohlanganisiwe uhlelo amayunithi, ngokuyinhloko kuhluke ngobukhulu, futhi, ngokufanelekile, abe negama generalized kanye ngezigaba lalo.

1. ikhompyutha siqu. Ajwayelekile kubo bonke abasebenzisi we ebhokisini lensimbi kungaba emasayizi nabobunjwa labehlukene. Ngenxa yalokho, bonke izingxenye akhethiwe ngayinye ebhulokini ngayinye.
2. ikhompyutha Mobile. Ephathekayo, ithebulethi, smartphone - konke amayunithi uhlelo, kuphela lehla ngamaphesenti izikhathi eziningana.
3. imishini Esincane-ugongolo. Amaseva, on-ebhodini amakhompyutha, ezikhumulweni nezinye ezikhethekile Computing zikagesi awela kulesi sigaba.

I-computer siqu ezivamile

Emakethe computer kunoma umthengi njalo ukukhetha: ukuthenga ababebuthene uhlelo amayunithi noma i isethi ezimele izingxenye, ukugxila intengo kanye nokusebenza kwendawo yesikhulumi. Ezimweni eziningi, abasebenzisi uthanda ukhetho lwesibili, ngoba inhlangano ngesandla njalo eshibhile. Futhi ibhizinisi lokukhiqiza platform isimo ngcono kakhulu. Nazi nje eziningi abathengi njalo wangazinaka umbandela eyodwa ebaluleke - ukuhambisana ihadiwe.

Enye into - eqoqwe ngokuya lonke uhlelo ibhizinisi iyunithi (HP, Intel, noma ngisho brand ezinye owaziwa kakhulu). Ngo ifektri, onjiniyela hhayi kuphela ukhethe izingxenye ehambisanayo kakhulu, futhi kwenziwa ikhompyutha ukusebenza ukuhlolwa, ukusebenza kohlelo lwaluyophola, kwencazelo wokubekezelela iphutha ngesikhathi imithwalo esiphezulu.

Market bekhompuyutha

Kunoma yikuphi esitolo okukhethekile umthengi ezingaba uzothola ukuthi wonke amakhompyutha abe imibala ehlukene hhayi kuphela, kodwa futhi ehlukile komunye nomunye ngezindlela ezihlukahlukene futhi ayilingani. Ngakho, emabhuloki umdlalo uhlelo ezibukeka zingalungile omkhulu (idinga Ukupholisa ehloniphekile) futhi emuva ehhovisi izinhlelo, Ngokuphambene, izinganekwane emfishane ukuze wonge isikhala kudeskithophu. Zonke amakhompuyutha, ngokulandelana, nezinye izinsimbi zabo, ihlukaniswa ngokweminyaka isici ifomu: ATX, miniATX, microATX, candy ibha kanye esigungwini.

Ngakho, i-uhlobo uhlelo iyunithi ngalinye has izindlu waso, owayeyisikhulu umbadlana, a ihluzo ikhadi futhi ukunwetshwa iyunithi. Zonke ezinye izingxenye (CPU, inkumbulo, nama-hard drive) kukhona jikelele futhi ingafakwa kunoma iyiphi ikhompyutha. Ifomu Factor - lena isici esiyinhloko unit uhlelo, okuyinto enquma isiphetho yesikhulumi kanye nenjongo yawo.

Ukukhetha Ofanele izingxenye

Isinyathelo esilandelayo ukukhethwa yomnikazi ikusasa ehambisanayo computer izesekeli. Kuyadingeka ukuba ichaze yesikhulumi, ngubani makudle - nomkhiqizi AMD noma Intel. Njengoba base bethole impendulo yalo mbuzo, kudingeka ukhethe umbadlana isizinda, okuzokwenza ube usayizi Uhlaka okuhambisanayo. Nazi ezinye umehluko wemisindo nemiqondo yamagama. Ngokwesibonelo, microATX umbadlana encane ngaphandle kwezinkinga kungenziwa aboshelwe omkhulu ebiyelwe ATX PC icala, kodwa kunalokho ukwenza umsebenzisi engasebenzi.

izinyathelo Okwalandela zidinga umthengi ukucacisa processor, RAM adaptha yevidiyo. Lapha ochwepheshe batusa ukuba makudle uhlelo olinganiselayo. Ukukhetha hard drive, drive optical kanye nezinye izingxenye incike computer uya khona. Ukuze amathoyizi kungcono ukuthatha esheshayo futhi kuyabiza SSD-drive futhi ehhovisi multimedia kungaba akukhetha idiski kazibuthe obunamandla. It kuvela ukuthi iyunithi uhlelo - lena umakhi evamile, okuyinto ungakwazi ukuqoqa ngokuthanda kwakho, nje kudingeka wazi ukuthi kufanele kwenzekeni ngenxa yalokho.

izinhlelo ephathekayo

ezisekelweni Sincishisiwe ekhaya kanye nokusetshenziswa ehhovisi Site ngaphezulu ngaphansi kwencazelo "monoblock". Isikhathi esining impela basuke kuqhathaniswa ne-laptop noma ithebhulethi. Into wukuthi noma yiliphi igama ezifakiwe ngaphakathi ikhompyutha, ngenxa Ubukhulu encane ebiyelwe ukusebenza kwabo kulinganiselwe kakhulu (uma iqhathaniswa PC ezivamile). Nokho, ngokulandela kahle futhi umkhiqizo wabo uthi yimuphi umsebenzisi oyedwa alikho. Thola okungenani yembobo uhlelo Intel iyunithi kokuba endaweni CPU amakhulu kunawo wonke endaweni I7 emhlabeni Core.

I ethile ye-laptops kuyinto umsebenzi elinganiselwe. Umsebenzisi kungaba ongenawo imizamo ukuze ungeze entsha, izingxenye ephezulu ukusebenza noma ukufaka noma yimaphi amakhadi ukunwetshwa. Kuyinto lo mkhawulo futhi ivumela abakhiqizi idivayisi yeselula ukulawula emakethe efanele, njalo ukuphoqa abasebenzisi ikhiqize kakhudlwana kumadivayisi abizayo.

imishini kakhulu ezikhethekile

Abathengisi abaningi bakholelwa ukuthi umdlalo uhlelo amayunithi kwakudingeka ukuba kuthiwe isigaba ewumngcingo-imishini, ngoba ezibizayo futhi iseva esikalini umbandela we "umkhiqizo". Nakuba kwakubiza, abalandeli eziningi kwezicelo ashukumisayo futhi kuyakhandla bazimisele ukukhokhela amakhulu ezinkulungwane ruble, nje ukuba yesikhulumi ezinamandla kakhulu emhlabeni, elikwaziyo ukuzigcina umsebenzisi in a virtual engokoqobo.

Nokho, imishini ezikhethekile ukusebenzisa uhlelo phezu HP iyunithi amisiwe njengoba iseva futhi yakhelwe ukusebenza nge yolwazi. Umehluko omkhulu uphezu evamile ukucutshungulwa ikhompyutha amandla. Abakhiqizi ezifana uhlelo amayunithi efakwe ngaphakathi ekhethekile izindlu motherboards ukuthi ukusekela izilimi eziningi. Futhi ezibucayi kwiseva inani RAM nama-hard drive. Ukudlala ku isimiso esinjalo umuntu singenakwenzeka uzokwazi, ngoba platform ayinayo leyehlukene ihluzo ikhadi, kanye ne-multi-million dollar izindleko imishini enjalo neze umuntu angakwazi ukukhokhela kusukela abasebenzisi ezijwayelekile.

Ekuphetheni

Ukubona ukuthi iyunithi uhlelo - kuba oyinkimbinkimbi ndawonye izingxenye computer, umfundi angakwazi kuphela ukwazi ukuthi ukuxhuma bese usebenzisa le platform ekhaya noma imvelo ehhovisi. Kulesi sigaba, kulula kakhulu, ngoba zonke abakhiqizi uhlupho olumayelana nabasebenzisi futhi uphile ejwayelekile olulodwa, edinga nezixhumi afanele zonke izesekeli nezithuthukisi umbala mshini.

Eyayembuleka uhlelo block uqobo ukuba ingxenye misa, umnikazi enquma ukuthi wonke terminals phezu umbadlana ube bobunjwa labehlukene, futhi ezinye izingxenye abahluke ngaso kwezinye umbala ngamunye. Ngakho, onsomi ikhibhodi isixhumi okufanele afakwe lunikeza ikhompyutha umbala contact. Gada negundane nazo afanele ubukhulu nezimbobo. Ngisho intambo uzokwazi yini ukufaka ngendlela efanele, ngoba zonke izimpahla amandla baye esakhelwe isisekelo.
