Chii chinonzi CPU?

The kombiyuta iri kunzwisisa pakati siyana mano revatema kuva chete chikwata Via bhazi (dzinobatsira dzakawanda zvinoriumba). Somuenzaniso, chimwe kombiyuta zvinosanganisira kuyeuka, CPU, mavhidhiyo adapteri, uye zvichingodaro. Unhu avo kuona uchitikurudzira yokupedzisira kuita uye zvinogonekwa. Chimwe chezvinhu zvinokosha zvinoriumba ndiyo musimboti kugadzira chimwe. Dzimwe nguva unogona kuwana mamwe zita rake: (. Eng Central Processing Unit - inokosha chairema kadambari) CPU, percent, ibwe.

Ndeipi CPU tichitarisa avhareji user? By muenzaniso womunhu muviri kunogona kufananidzwa muzana wouropi. It anoita zvose akarongeka computations, uye pamwe rinopa kudyidzana pakati zvinoriumba. Panyama, asi processor ndiko kuri Chip iri kuiswa mune chaiyo slots pamusoro motherboard. Inside rine kunzwisisa pfungwa nematunhu ose mabhiriyoni akawanda transistors. Vanhu vaifarira mubvunzo "chii CPU», nyore unogona kuona processor kune dzimwe zvinorwisana zvinoriumba. Mushure zvose, nguva dzose basa kutonhora hurongwa: guru kupisa simbi singi uye feni. Vaifanira nokuti kuti kudyiwa chip fari zvemagetsi simba kazhinji makumi ezviuru watts or. Small vhoriyamu vaparadzirwa nomumativi kutungamirira yakakwirira nesimba kudziyisa muviri CPU inoda kutonhora.

Processor vagadziri zvakasiyana kusarudza kudziyisa mubvunzo: mumwe optimized mapurani, zvichiita zvigadziriswe chokukuvadza tsva kutigumbura, vamwe yakaderera simba wedzerai voltage uye rinoshandiswa kubudisa ichangobva kuitwa ( "dzakaonda" muitiro michina), etc. Pari chikuru "vatambi" pamisika nechepakati processors. desktops uye Laptops vari mapoka maviri - Intel uye AMD. Saizvozvowo, vamwe kwezvivako iri kugadziridzwa kuti hunhu zvigadzirwa zvavo.

Kazhinji mubvunzo "chii CPU» kupa nokururamisira generalize mhinduro. Izvi zvinogona kutsanangurwa chaizvo nyore: Zvino shoko rokuti "processor" awana anoreva hwakafara kupfuura "chikamu kombiyuta." Saka, chero ano runharembozha ane chikwata kuti anoita masvomhu - iri rine processor. Kunyange varidzi matoyi akakwanisa vana zvinobatsira kuziva zvinotaurwa CPU, nekuti ivo kuuya computational chimwe.

Zviri pachena kuti haana vaiona musimboti nokushanda processor, kunzwisisa mukuru unhu basa rake hazviiti. CPU kushanda kuzvidzora chirongwa. Ndivo anoita mirayiridzo nokuda processor, rakanyorwa chero mutauro zvirongwa. Kumunhu kutaura, purogiramu Isa chaiyo muitiro. Munhu wose anoyeuka kana wakanzwa Basic zvirongwa mutauro. Mariri, kuti vaswedere denderedzwa pamusoro chidzitiro aifanira kuita murayiro Circle (Coordinates). Modern misimboti chepurogiramu ndewokuti: basa kuumba chikwata mapurogiramu mitauro. Kana uchimhanya purogiramu pakombiyuta rinokosha-software decoder vatendeuki nokurayira mutauro wakashandiswa muchina remitemo kuti zvakananga kubudiswa pamusoro CPU. Bumbiro iri - binary, rinomiririra kutevedzana kwezviitiko vaya uye zeros. Vakawanda havagoni kunzwisisa nei vakasarudza kushandisa mashoko binary hurongwa, pane zvavaisiita ari grade. Kutaura zvazviri, zvose zvinotsanangurwa chaizvo nyore: nematomhu Kubvuma mirayiro nyore kune transistors pachavo. Somuenzaniso, sezvo tiri kutaura pamusoro digitaalinen mano, unogona kufungidzira nhamba "1" sezvo kuvapo voltage pahwaro imwe transistor, uye "0" - se asipo. Saizvozvowo, mumutsetse wokutanga, asi transistor kuzarurwa uye iyezvino ichipfuura pacharo, uye yechipiri - rakakiyiwa (Chokwadi, zvose nyore uye ane muzvizhinji kuti ndishushikane).

Mwero Kuurayiwa mirairo chirongwa kunotema yacho processor nokukurumidza. Izvi sei mavakirwo, kakawanda pamusoro womukati hushande basa, optimizing bumbiro remitemo.
