Yintoni i CPU?

I-khompyutha imbaxa yamacebo ezahlukeneyo yayanyaniswe iyunithi enye nge ibhasi (luncedo kumacandelo lwangaphakathi). Umzekelo, nayiphi na ikhompyutha iquka inkumbulo, CPU, iadaptha iividiyo, njalo njalo. Iimpawu zabo ukuqinisekisa intsebenzo iyonke zokugqibela nezakhono. Enye yeendima ezibalulekileyo yeyona iyunithi yokusebenza engundoqo. Ngamanye amaxesha ungakwazi ukufumana elinye igama lakhe: (. Eng Central Processing Unit - iyunithi esisiseko becomputing) CPU, Percents, ilitye.

Yintoni i CPU ngokwemiqathango kumndilili womsebenzisi we? Ngu umzekeliso umzimba womntu uyakwazi ukuba kuthelekiswa ekhulwini ingqondo. Iqhuba zonke zibalo zemathematika, kwaye ngenxalenye sinika intsebenziswano phakathi kwamalungu. Emzimbeni, iprosesa na chip inkulu efakwe kwi slot ekhethekileyo motherboard. Ngaphakathi iqulathe iziphaluka logic oluntsonkothileyo transistors billion eziliqela. Abantu abanomdla umbuzo othi "yintoni na» CPU, ngokulula ukwazi ukubona kumqhubekekisi kwamanye amacandelo zangaphakathi. Ngapha koko, oko kusoloko inkqubo esebenzayo Ukupholisa: enkulu kumgxobhozo ubushushu intsimbi kunye fan. Imfuneko kubo ngenxa yokuba kuselelwe chip ngamandla ombane kudla amashumi Watts. umphezulu volume uchitha ezincinane kukhokelela yamandla aphezulu zokufudumeza umzimba CPU efuna kobubi.

abavelisi iprosesa ngokwahlukileyo isigqibo umbuzo ukufudumeza: omnye bokwakha eliphezulu, ukwenza iindlela ukukhubaza iibhloko ezingasetyenziswanga, ezinye unikezelo amandla ombane aphantsi kwaye isetyenziswe ukuvelisa kwimpumelelo yakutshanje ( "obhityileyo" inkqubo technology), njl Okwangoku, i "abadlali 'eziphambili kurhwebo lwe iziqhubekisi engundoqo. i desktops ozifunayo kwaye laptop iinkampani ezimbini - Intel kunye AMD. Ngako oko, ezinye izibonelelo lihambisane iimpawu iimveliso zabo.

Amaxesha amaninzi lo mbuzo, "yintoni le CPU» ukunika ngeranti iimeko iimpendulo. Oku kuchazwa kakhulu nje; kaloku igama elithi "iprosesa" ifumene zinentsingiselo ngokubanzi kwe "yinxalenye computer." Ngoko ke, kuyo nayiphi na ifowuni mihla yeselula iyunithi eyenza izibalo - kananjalo a kumqhubekekisi. Nkqu abanini zokudlala abantwana ezilawulwa kukuba luncedo ukwazi ukuba yintoni na CPU; kuba ziza nezazo iyunithi azo.

Licacile elokuba, ukuba akujongwa umgaqo osebenza kuyo iprosesa, ukuba aqonde iimpawu ngokubanzi akunakwenzeka umsebenzi wakhe. inkqubo yolawulo operation CPU. Bona iiseti imiyalelo kumqhubekekisi, abhalwe kulo naluphi na ulwimi lokuprograma. Ngokubona, inkqubo Misela inkqubo ngqo. Wonke ukhumbula okanye ubuncinane weva ulwimi Basic kweenkqubo. Kuyo, ukuze bazobe isangqa kwi kwikhusi kwakufuneka enze umyalelo Biyela (ezihambelanayo). imigaqo Modern lwenkqubo kuhlala olufanayo: umsebenzi ukwenza iqela iilwimi kweenkqubo. Xa usenza i lwenkqubo kwi khompyutha a software idikhowuda ezizodwa iguqula umyalelo we ulwimi olusetyenziswa ikhowudi umatshini processing ngqo kwi-CPU. Le code - yokubini, imele ukulandelelana abo kunye amaqanda. Amaninzi ukuqonda isizathu sokuba kwagqitywa ukuba usebenzise inkqubo yokubini, kunokuba Njengesiqhelo lokugqibela. Enyanisweni, yonke into kuchazwe kakhulu nje: ezi amasuntswana ngokulula angenise njengemiyalelo transistors ngokwabo. Ngokomzekelo, ekubeni sithetha izixhobo yedijithali, ungabona inani "1" njengoko ubukho ombane kwi Ngokwesiseko transistor ethile, yaye "0" - njengoko engekho. Ngako oko, kwimeko yokuqala, lo transistor ivulwa kwaye ngoku idlula ngokwawo, kunye yesibini - ivaliwe (Kakade ke, bonke lula kwaye kukho ezininzi ubhukisho).

Izinga ukubulawa imiyalelo lwenkqubo limisela isantya iprosesa. Oku abachatshazelwa izakhiwo, amaza busebenze lwangaphakathi komsebenzi, ukukhulisa ikhowudi.
