Isikhathi, inkumbulo futhi PC ukusebenza

ngezinye izikhathi Computer amagama besesitelekeni yinkimbinkimbi kwako. Ngenxa yalokhu, umsebenzisi futhi ngesikhathi esifanayo umthengi lokugcina ibhekene nezinkinga ezithile ngenkathi uthenga ikhompyutha noma ukubuyekeza ukucushwa yayo. Ukuze esinye sezici ezibaluleke kakhulu PC yiyona okuthiwa isikhathi. RAM libhekene njengoba ipharamitha imvamisa, esebenza kuwo kanye ubukhulu ukubambezeleka ukwelashwa kwezinye amamojuli computer.

Ngaphambi kokuya ukuphendula umbuzo yini isikhathi, sichaza isimiso esiyisisekelo RAM - okungahleliwe ukufinyelela inkumbulo.

ukuthini "RAM" Indlela

uHlelo Lwesiqondisi Kungena Esilula (RAM, RAM) - ingenye ingxenye ebaluleke kakhulu kunoma iyiphi ikhompyutha. It ilondoloza okwesikhashana idatha ezidingekile ukusebenza kwe-processor. Ukudlulisela ukwaziswa kulesi simo senzeka ngokuqondile isitoreji unit nucleus noma ngokusebenzisa unenkumbulo ekhethekile ultra-fast. Ngamagama alula, imemori - a microchip okugcina ukwaziswa abelokhu ambalwa ukugcina idatha kuzo zonke izinhlelo umsebenzisi egijima. Kodwa akunakwenzeka yini ukugcina konke kwi-hard drive yakho, kungcono futhi imemori? Ngeshwa cha. Lonke iphuzu nesivinini. I hard disk drive yidivayisi mechanical nge ongaphakeme isivinini yokusebenza (kuqhathaniswa nezidingo CPU) kanye ngengcebo enomkhawulo. RAM ayinayo lezi yokuntula, ke iyashesha, nokuphila kwaso akuxhomekile inani hits.

ngezigaba

Kukhona futhi izinhlobo ezimbili zezinkantolo inkumbulo:

• SRAM - static RAM uhlobo;
• Dram - ashukumisayo uhlobo RAM.

Ngaphandle kokuya zonke izici lobuchwepheshe ukugcwaliseka SRAM-inkumbulo kungashiwo ukuthi emapheshana enjalo kuyashesha. Futhi ukubambezeleka ukuthumela idatha ku block RAM kwenzeka ngokuphazima kweso. Ngeshwa, zibiza kakhulu ukuqaliswa enjalo lihlukile. Ngaphezu kwalokho, umthamo we module inkumbulo anqunyelwe usayizi kuqhathaniswa enkulu transistors. SRAM amamojuli ezisetshenziswa njengeziwusizo isilondolozi inkumbulo ultra-fast, isetshenziswa ku izilimi, hard drive, kanye nezinye amamojuli ikhompyutha.

I ashukumisayo uhlobo RAM - yilokho emapheshana evamile elingunxande, okuyinto zitholakala kwi umbadlana. Lokhu inkumbulo has a izindleko iphansana futhi ivolumu ephezulu. Kodwa amayunithi ayo zinezithiyo ezithile:

• Kusukela strip iqukethe capacitor, kubalulekile ukuba njalo 'ezivuselela "ikhokhiswe kubo ukuze idatha elahlekile. Lo msebenzi wenziwa CPU. Kodwa ngesikhathi ukufinyelela inkumbulo ezifana okwesikhashana yonke imisebenzi nalo.
• Ijubane lokhu ipulangwe lincane kakhulu static.
• Kufeza indima ebalulekile futhi akhethiwe kahle isikhathi. RAM nge omningi futhi imvamisa high akuzona njalo ukubonisa umkhiqizo ezidingekayo ngenxa ukubambezeleka okusezingeni eliphezulu.

Izinhlobo RAM

Okwamanje, kunezinhlobo 4 izinhlobo inkumbulo amamojuli:

• DDR - yisikhathi RAM uhlobo esetshenziswa kumakhompyutha endala kakhulu.
• DDR2 - efana amabhlogo we-RAM ingasatholakala e PC amadala ejensi kahulumeni kanye nezikhungo zemfundo. Ijubane lokhu inkumbulo ayikuvumeli ukuba babhekane nezimo zokusebenza ezisindayo-yesimanje, kodwa kwanele lokucubungula igama evule i-Internet.
• DDR3 - okuvame kakhulu inkumbulo mojuli. Ukusetshenziswa kwamandla kagesi incane 40% kunanoma e uhlobo esandulele, ezifana inkumbulo nesivinini yokusebenza iphezulu kakhulu.
• DDR4 - ukuziphendukela kwemvelo RAM. Lezi amamojuli bayakwazi ngokugcwele zonke izimfuno umsebenzisi yesimanje. Lapho elikhulu ukucushwa iyunithi anganikeza throughput elilingana 34.1 GB / c.

inkumbulo izikhathi

Manje siyazi ukuthi RAM. Nokho, luyini isikhathi? Lokhu olephakathi ukuthumela ukuqaliswa imemori ibhasi isiqhema kukalwa ngemijikelezo.

Dram siqukethe amaseli zenziwe afanayo mgudumbili. Isakhiwo iyafana eheleni, lapho kukhona iseli amasayithi. Ukuze ufinyelele ISIZINDA isilawuli kumele wazi ikheli yabo, ehlanganisa irowu kanye ikholomu izinombolo (izixhumanisi). I afanayo umuntu usayizi ofanayo kumaseli ezihlanganiswe amabhange okuthiwa.

Ngakho, isilawuli efinyelela ngowokuqala yasebhange irowu isignali ikheli RAS ngokusebenzisa. Khona-ke ukufuna umugqa kudingekile - kuyinto RAS umjikelezo isikhathi ukuze CAS Ukubambezeleka. Ngemva kwalokho, isilawuli ithumela inombolo ikholomu CAS-isignali. Kulindwe Ngempendulo yesicelo enjalo ibizwa ngokuthi CAS ukungaphumeleli. Isikhathi ngokuthi RAS Precharge umyalo yisikhathi phakathi zokuvalwa kusebenze umugqa, Active Precharge Ukubambezeleka - phakathi kusebenze futhi imiyalo ukuvala. Umyalo Ukukala - iyona isikhawu esincane phakathi yimuphi amaqembu amabili.

Uma ukuthenga RAM ibha entsha kungaba lula kakhulu ukunquma isikhathi. RAM esinelebuli isikimu ejwayelekile: DDR3 (imvamisa) CAS latency - RAS ukuba CAS DELAY - RAS Precharge - Cycle Time, empeleni libukeka DDR3 2133 9-12-12-28.

Yikuphi okungcono - inkumbulo fast noma ukubambezeleka kancane?

Into yokuqala ukuba banake isikhathi. RAM nge imvamisa eliphezulu kungahamba kancane, ngoba isikhalo wokugaya has a isivinini ephansi kakhulu, futhi ngakho inzuzo ngeke waqaphela. Ngesikhathi esifanayo, ukubambezeleka zihlale ezingeni ejwayelekile Yiqiniso, uma ungenawo ukubeka izikhathi RAM ngesandla.

Ngakho, ngokwesibonelo, ka DDR2 inkumbulo 1600 6-7-6-18 ngokushesha okuningi kunalokho DDR3 1866 9-9-9-24. Njengoba ubona, esimweni sesibili sinawo isizukulwane esiphelele RAM ngesilinganiso ephakeme, kodwa ukubambezeleka kakhulu nje negate leli qiniso. Ngokuthenga inkumbulo amasha, zama ukukhetha imodeli lowo ubuncane ukubambezeleka kungenzeka. Le ndlela ukuqinisekisa ngokwakho okusezingeni eliphezulu ukusebenza computer iyonke.
