Ko Kubvisa kubva 32 kusvika ku 64-bits Kuvandudza Computing?
Nhanganyaya
Panguva ino, makombiyuta ose uye desktop makombiyuta evanhu akachinja kubva 32-bit kusvika 64-bit processors. Kunyange zvazvo iyi ndiyo mhaka, mamwe makombiyuta achiripo 32-bit versions eWindows ane zvimwe zvine chokuita nekurangarira kwavanogona kuwana. Icho chichiri mashomanana mashomanana ekugadzirisa mafoni anoshandiswa anoshandisa 32-bit kunyange zvakadaro nei software iri ichiripo.
Nzvimbo huru iyo 32-bit ne 64-bit processing ndiyo nyaya ine chokuita nekombiyuta mapurisa . Mazhinji mafoni efoni uye mahwendefa iye zvino achiri kushandisa 32-bit processors. Izvi zvinonyanya kukosha kunowanzove yakanyatsobudirira kana zvasvika pamashandisirwo emagetsi avo uye hardware isati yasara kuburikidza nehukuru. Kunyange zvakadaro, 64-bit mapurogiramu ari kuwanda zvakajeka saka iyo pfungwa yakanaka kunzwisisa uko 32-bit ne 64-bit processor inogona kukanganisa mawakombiyuta ako.
Kunzwisisa Bits
Zvose zvinowanzogadzirwa nekombiyuta zvinowanikwa pamatanha emabhadhari nekuda kwezvinotenderera zvinosanganisira semiconductors mukati memaputi. Kuisa zvinhu nenzira iri nyore, zvishoma chete 1 kana kuti imwe chete kana kuchengetwa pane yakashandurwa nechitenderi. Zvose zvinogadziridzwa zvinotumidzwa nehutano hwavo hwekugadzira. Kune vakawanda vatsva zvino, iyi i-64-bits asi kune vamwe, zvingave zvichiri kukwana kune 32-bits chete. Saka chii chinonzi bit count?
Ichi chiduku chiduku cheprootorori chinogadzira nhamba huru yenhamba iyo inogona kugadzirisa. Nhamba huru iyo inogona kushandiswa mumutambo weawa imwe chete ichave yakaenzana ne 2 kusvika kune simba (kana kuratidza) kwechidiki. Nokudaro, 32-bit processor inogona kubata nhamba kusvika kusvika 2 ^ 32 kana inenge 4.3 mabhiriyoni. Nhamba ipi neipi yakakura kudarika iyi inoda kudarika nguva imwechete yevhavha yekuita. A 64-bit processor, kune rumwe rutivi, inogona kubata nhamba ye2 ^ 64 kana inosvika 18.4 quintillion (18,400,000,000,000,000,000). Izvi zvinoreva kuti 64-bit processor inokwanisa kukwanisa kunyatsobata mashoma mathematics. Iye zvino mapurogiramu haasi kungoita mathemoni chete asi iyo tsvimbo yakareba inoreva kuti inogona kupedza mirairo yakafambisa mberi mune imwe nguva yevhavha yekutengesa panzvimbo yekuti iparadzanise kuva yakawanda.
Saka, kana iwe une maitiro maviri akafanana anofambisa paawa imwechete inokurumidza kupiwa mirairo yakafanana yeprogram, 64-bit processor inogona kubudirira kaviri nokukurumidza se 32-bit processor. Izvi hazvirevi chokwadi zvachose nokuti rimwe nerimwe reawa haritauri kushandisa zvese mumapfu asi chero nguva iyo yakakura kudarika 32, 64 bit inotora hafu yenguva yekuraira.
Chiyeuchidzo ndicho Chinokosha
Chimwe chezvimwe zvinhu zvakananga zvakanzwisiswa nehuwandu hwechidiki chepurogiramu nderemuwandu hwekuyeuka iyo nzira inogona kutsigira nekuwana. Ngatitarisei mazamu ema-32-bit mapurisa ezuva ranhasi. Iye zvino 32-bit processor uye maitiro anoshanda anogona kutsigira huwandu hwe 4 gigabytes yekuyeuka mumakombiyuta. Pakati pe 4 gigabytes yekuyeuka, maitiro ekushanda anogona kungopa 2 gigabytes yemusoro kune imwe shanduro.
Izvi zvinonyanya kukosha kana zvasvika kune laptop uye desktop makombiyuta ega . Izvi ndezvekuti vane ruzivo rwezvirongwa zvakaoma zvakanyanya uye zvikumbiro kusataurira nzvimbo yekuyeuka kwevanonyorera. Mobile mafambiro, kune rumwe rutivi, ane nzvimbo shoma uye kazhinji ane memori yakabatanidzwa mukati mekugadzirisa. Semugumisiro, kunyange magumo ekugadzirisa mapefoni emafoneti nemahwendefa akawanda ane 2GB chete yekuyeuka kuitira kuti irege kusvika pamiganhu yeGG.
Sei nyaya iyi? Zvakanaka, kukosha kwekuyeuka iyo projekiti yakakanganisa kuoma kwezvirongwa. Mahwendefa mazhinji maduku uye mafoni haana simba rekushandisa zvikumbiro zvakanyanya zvakadai sema Photoshop . Ichi ndicho chikonzero kambani yakafanana neAdobe inofanira kuisa mamwe maitiro akawanda anoita zvikamu zvakasiyana-siyana zvepurogiramu imwechete yakanyanya PC inogona. Nokushandisa 32-bit processor nemiganhu yayo yekuyeuka, haizombofi yakagadzikana nehutano hwakafanana hwehutano hwakakonzerwa nemakombiyuta akazara ega.
Chii chinonzi 64-bit CPU isina 64-bit OS?
Kubva ikozvino tave tichitaura pamusoro pehutano hwevashanduri vanovakirwa pamasvingo avo, asi kune chinhu chinokosha chinofanira kuitwa pano. Kushandiswa kwakakwana kwepurogiramu kunongova kwakanaka sezvinonzi software yakanyorerwa iyo. Kumhanya 64-bit processor ne 32-bit operating system ichaguma kuparadza huwandu hwakawanda hwekombiyuta yekushandura. Iyo-32-bit operation system inongoshandisa hafu ye registers yeprojekisera saka inogadzirisa iyo inyanzvi yekombiyuta. Icharamba ichiine zvikanganiso zvakafanana pamusoro payo kuti pane 32-bit processor iripo ine OS imwe chete.
Izvi chaizvoizvo dambudziko guru chaizvo. Yakawanda yekuvakwa kwekugadzira yakafanana neye 64-bit inogadzirisa zvinowanzodikanwa kuti zvigadziriswe zvitsva zvezvirongwa zvinyorwa kwavari. Iri dambudziko guru kune vose vanogadzira hardware uye software vanoita. Makambani e-software haadi kunyora software itsva kusvikira hardware iri kunze uko kutsigira software yekutengesa. Zvechokwadi, hardware vanhu havagoni kutengesa chigadzirwa chavo kunze kwekunge kune software yekutsigira iyo. Ichi ndicho chimwe chezvikonzero zvikuru nei mabhizinesi eCUU akadai seIA-64 Itanium kubva kuIntel aine matambudziko. Pakanga pane zvinyorwa zvinyorwa zvinyorwa zvekuvakwa uye iyo-32-bit emulation yekushandura maitiro ese aripo akakuvadza zvikuru CPU.
Saka, AMD neApple vari kutenderera sei dambudziko iri? Apple yakatanga kuwedzera 64-bit patches nokuda kwekushanda kwayo. Izvi zvinowedzera humwe hutsigiro, asi huchiri kushanda pa 32-bit OS. AMD yatora nzira yakasiyana. Yakagadzira purogiramu yayo yekubata maitiro e-x86 32-bit maitiro ekushanda uye akawedzera mamwe mabhuku e 64-bit. Izvi zvinobvumira mushanduri kuti atange 32-bit code pakuchengetedza se 32-bit processor, asi nezvino 64-bit versions yeLinux kana kuti yeWindows XP 64 iri kuuya ichashandisa kushandiswa kwakakwana kunokwanisa kweCUU.
Ndiyo Nguva Yakakodzera 64-Bit Computing?
Mhinduro kumubvunzo uyu ndeyee uye kwete. Imhizha iyi inosvika kumiganhu ye 32-bit computing kune zvakawanda zvepamusoro pamakambani emakombiyuta ekupedzisira zvakadai semabhizimisi nevanoshandisa simba. Kana makombiyuta ari kuwedzera mukukura uye kushandiswa kwesimba, zvakakosha kuita kuti svetuka kune chizvarwa chinotevera chekugadzirisa. Aya ndiwo maitiro anowanzodikanwa zvakanyanya kukuyeuka uye kuwanda kwenhamba kuverengeka iyo ichawana zvakanakira zvakanakira 64-bit platform.
Vashandi vari nyaya yakasiyana. Zvizhinji zvemabasa ayo muvhareji anowanzoita pane kombiyuta zvinopfuura zvakakwana zvakafukidzirwa nemapurani e 32-bit. Pakupedzisira, vashandisi vachasvika pakanoshandiswa kushanduka ku 64-bit computing kunonzwisisika, asi ikozvino hazviiti. Vangani vatengi kunze uko vangangodaro vane 4 gigabytes yekuyeuka mune kombiyuta kunyange mumakore maviri anotevera?
Ichokwadi zvikomborero zve 64-bit computing zvinozopedzisira zvichisvika pasi kune vatengi. Vachigadzira uye vashandisi vekugadzira vanofarira kukodzera zvakasiyana-siyana zvezvinhu zvavanofanira kutsigira kuedza nekudzikisa mari. Nekuda kweizvi, ivo vachapedzisira vaisa pfungwa pakugadzirwa kwe 64-bit hardware uye software. Kusvikira panguva iyo, kuchava kukwira kunotyisa kune avo vanosarudza kuva vekutanga kutora.
