PC - ib qho zoo tagnrho lub cuab tam rau feem ntau lub hom phiaj

Tej computer - yog ib tug siv hluav taws xob tsim los daws tau ntau yam teeb meem. Nws muaj ntau npaum li cas mus rau hauv peb lub neej uas peb tsis tau ua tsis tau nws. Accounting, engineering, luam - qhov no yog tsis yog ib tug ua tiav daim ntawv teev cov neeg lag luam uas ib tug neeg tsis muaj nws pab tsis tau dab tsi.

Tus thawj tus kheej lub computer Kua II nyob rau hauv 1977. Li no taw tes, computers twb pib xyaum ua uas thiab twb tsis ntau. Tsuas yog nws cov thawj, nrog ib tug Performance index ntawm «Kuv» khav ib ncig ntawm ib puas luam. Tab sis cov kua II muag ntau tshaj li 5 lab daim. Lub computer yog lub brainchild ntawm ob ci ntsa iab txiv neej. Ib tug ntawm lawv - Stiv Voznyak. Nws yog nws leej twg yog lub luag hauj lwm rau cov kev ib feem ntawm cov nqe lus nug. Tab sis lub thib ob - Stiv Dzhobs - tau txais kev pab raws li ib tug generator ntawm lub tswv yim.

Kom txog rau thaum xyoo 1981, cov leading txoj hauj lwm nyob rau hauv qhuav ntawm computers nyob los ntawm cov kua. Ces nws yog nyob rau qhov no qhov chaw nias ua ke los ntawm IBM thiab Microsoft, Intel thiab AMD. Twb nyob rau ntawm lub sij hawm nws yog tseeb hais tias koj tus kheej lub computer - qhov no yog dab tsi yuav hloov lub neej ntawm ib tug neeg. Tus thawj loj txoj kev loj hlob nyob rau hauv daim teb no, Intel los ua tus processor 8086. Nws yog nws ob nuj nqis thiab muab lub npe ntawm lub feem ntau tsim platform - "x 86". Ces muaj 80286, 80386 thiab 80486. Thiab lub CPU nrog lub npav ua tsis tau tsuas yog lub Intel, tab sis AMD, WinChip thiab ntau lwm tuam txhab uas muag. Khaus sib txeeb tau coj mus rau ib tug dynamic txoj kev loj hlob ntawm "x 86" kev txiav txim siab hais tias tus so tau nyuaj los sib tw.

Cov tom ntej no nyob rau hauv tsev neeg no yuav tsum tau 80586. Tab sis qhov no tsis tshwm sim. Corporation "Intel" xav patent ib tug lag luam tawm kos, tab sis nyob rau hauv cov nqe lus ntawm American txoj cai yog tsis pub ua. Raws li ib tug tshwm sim, nws yog tsim nyog los hloov lub numeric cim nyob rau hauv pentium. Kos npe rau yog cov hloov ntawm lub PRO nrog ib tug Performance index cov no processor tsev neeg. Lawv yog ib tug ob peb daim mounted rau ib tug board. Thiab nws yog ib tug txhob nyob hauv lub sij hawm. Qhov thib ob kev ua tau zoo ntawm MMX tau txais index. Nws muaj tshaj qhia teeb, uas simplifies lub tuav ntawm multimedia ntaub ntawv. Nyob rau hauv lub lig Kwvyees li xyoo 1990 lub xib-teg Intel kev cuam tshuam AMD. Nws tso lub Athlon thiab Duron CPU, uas thaum lub sij hawm ntawm unparalleled kev kawm. Nrog lawv tawm, nws tau los ua tseeb hais tias cov tus kheej lub computer - yog ib tug ntau yam kev lom zem chaw. Nws yog ua tau mus saib ib tug yeeb yam, mloog suab paj nruag, ua si ua si. Yog, thiab kos duab yog tsis yooj yim. Qhov kawg tseem ceeb tshwm sim tshwm sim nyob rau hauv nruab nrab-2000s. Ces, yuav luag tib lub sij hawm, Intel thiab AMD tau kev nyob rau hauv ib processor nrog 2 cores. Qhov no pub rau cov sij hawm los ua kom productivity.

Thiab tam sim no?

Tam sim no ib tug tus kheej lub computer - ib lub tshuab uas yog siv nyob rau hauv tag nrho cov spheres ntawm tib neeg lub neej. Yog hais tias thaum pib ntawm lub zaus ntsuas nyob rau hauv megahertz processor, thaum lub caij ntawm 2-3 GHz tsis muaj surprise. Thiab muaj cov tseem nrov kuaj raws li FX-9590, nrog ib zaus ntawm 5GHz. Nyob rau hauv lem, lub graphics yog "computer mus rau lub computer". Lawv theem ntawm kev ua tau zoo piv nrog ib co nkag-qib systems. Yog hais tias thaum pib ntawm xyoo 1980 rau 128 kb yog txaus rau cov hauj lwm, thiab tam sim no ib co 32 GB yog tsis txaus. Puas muaj ib tug system uas twb 64 Gb muaj nqis. Lub peev xwm no kuj ho muaj zog. Yog hais tias koj nruab qhov rais 95 yog txaus rau 100 MB, tab sis tam sim no muaj cov 1 kab mob TB yog twb nyob qhov txhia qhov.

Niaj hnub nimno tus kheej lub computer - yog   ib tug yuav tsum cwj pwm ntawm kev vam meej kev lub tuam txhab. Nws tso cai rau ob peb lub sij hawm mus kom tsim tau thiab los daws kom tau lub feem ntau ntau haiv neeg paub tab. Grand leap uas ua microelectronics dhau tus xeem 30 xyoo, nws yog ib qhov nyuaj rau kev ntsuam xyuas. Tab sis ib tug nrog ib tug zoo kawg degree ntawm qhov muaj tseeb - tsis yog cov kev txwv! Thiab twv seb dab tsi yuav tshwm sim tom ntej no, nws yog heev yooj yim.
