Computer memory lwangaphandle

Umxholo nqaku yanamhlanje yeyona imemori yangaphandle ye computer. Kodwa kuqala Ndingathanda ukuthetha amazwi ambalwa malunga isiphoso omnye, nto leyo wazingqina kakhulu "ukunamathela". Enye esikolweni izifundo xa befunda lwangaphakathi isixhobo inkqubo block , phakathi kwezinye izinto ucacise yingxenye eyodwa kubalulekile - RAM. Emzimbeni, oko limelwe iitshiphusi soldered kwi textolite iplanga kunye imikrozo emibini (ikama), ukutyibilika abafowunelwa, edityaniswe kwibhodi indlela. Ngokomzekelo, xa bathi akukho nkumbulo yaneleyo, oko kuthetha ukuba imali encinci RAM. Nokuba jikelele okanye ezinye izicelo. Noko ke, maxa wambi ukusetyenziswa kwegama elithi "imemori yangaphandle". Oku akunjalo, ubuncinane ngenxa yokuba, umzekelo, akakho umntu eza kunye ingcamango ukubiza ethi "imemori". Le ncwadi - oko eendaba, kwaye memory - yinto eyahlukileyo.

Yintoni ezithile ukuthini igama elithi "imemori yangaphandle '? Xa RAM ikhankanywe ngasentla sele kunzima ebalulekileyo, esizibonakalisa kwi ukulahleka zonke data egcinwe kwi chip ye iseli wean amandla nganye. Ngoko ke, oko isetyenziswa kuphela xa ikhompyutha kwamiliselwa iiprojekthi izibalo zangoku, kwaye ixesha elide yokugcina data imemori yangaphandle iyasetyenziswa. Oku hard drive, flash drive, i drive funda / bhala CD-ROM drive, nkqu umshicileli, kunye bamathidala. Oko kukuthi, zonke iingcinga apho ingqibelelo idatha akaxhomekekanga phambi umbane.

Zonke iifayile yomsebenzisi, kubandakanya nenkqubo yokusebenza, ezigcinwe njenge. Xa kuthelekiswa ne RAM, ezi zixhobo kufuneka lukhulu sikhundla, kwaye kwezinye iimeko phantse mda. Umzekelo, xa umthamo iimodyuli ye computer mihla umlinganiselo 4-8 GB, ubungakanani hard drive yi kunqabile ngaphantsi kwe 250 GB. Ukusebenzisa yokugcina ifayile elisusekayo (CD-ROM), unako, ngethiyori, ndisindise uthotho data.

imemori yangaphandle inikwa ngokwasemzimbeni kunye izixhobo zokugcina kwimigaqo ezahlukeneyo yokusebenza. Enye yezinto zokuqala ezi izisombululo i floppy diski. Le zeendawana polymeric bhetyebhetye ngohlobo idiski isale yayisoma ngemagnethi, komhlaba apho ngokukhethekileyo magnetizable drive lokurekhoda intloko. Lo mgaqo phantse ziyafana amakhasethi endala for audio neevidiyo nezixhobo.

Phantse ngexesha elifanayo akuba ukuphucuka izisombululo zezakhiwo, ogama eWinchester. Izindlu wabeka ngandlel engaguquki drive yangoku ngento nonconductive, isale umaleko ngemagnethi. Ekubeni intloko ukurekhodwa ayikho ngqo wadibana kumphezulu, "moya" emoyeni umlambo unako ukubavusa kakhulu isantya ujikelezo disc, yaye ngoko, ukusebenza yonke device.

Umgaqo ehlukileyo yokusebenza lisetyenziswa drives for yokufunda / ubhale CD-ROM drive. Ngokutsho iqela yekhompyutha ye-laser umqadi ngendlela matshini ethile ndlela vee zesinyithi. Xa ufunda efanayo umqadi kubonakala ukusuka umaleko esipilini baxhaswa, a photocell ifakwe zihlalutywe. Ngaloo ndlela yokufumana ulwazi ezirekhodiweyo.

Ezi ezinye iintlobo izixhobo memory. Hi ndlela leyi, ngethuba 8086 yokuqala sisigqibo iikhompyutha apho, leyo ukumenza kubizwa inkumbulo bangaphandle. Zizo ezo isambuku iimodyuli ukwanda RAM, leyo ezigcinwe ngaphakathi nj. Ngokungafaniyo imivalo mihla ukuba lentwana a yangaphandle ngokwenene.
