Imbali izinto ezigcina iinkcukacha ngokufutshane

bonke Siye weva into efana lwazi. Kuba ngeenxa zonke kuthi, akunakwenzeka ngaphandle ubomi bethu. Kodwa yintoni esiyaziyo ulwazi ngokwayo, iifomu zawo, iindlela, iindlela zokugcina. Kwaye Ngaba Siyazi ngembali iindlela zokugcina? Makhe sijonge ngakumbi.

definition kolwazi

Ngaphambi kokuba uthethe izixhobo zokugcina, bathi isibini yamagama malunga inkcazelo yolwazi. Ke ukuba ukuhlalutya indlela processing kunye nokugcinwa, kwakunye ufunde lo mbuzo, njengoko kwimbali yokugcina ulwazi ithetha.

Ukuza kuthi ga ngoku, akukho nkcazelo nye ecacileyo kwaye okuvunyelwana jikelele kolwazi. Ngoko ke, ngokusekelwe nobuninzi kweekhonsepthi ezikhoyo, kunokuthiwa ukuba ingcaciso - oko ulwazi okanye iinkcukacha malunga into okanye umntu. angaqokelelwa Olu lwazi, luyasetyenzwa igcinwe, esetyenziselwa iinjongo ezahlukeneyo. Omnye imisebenzi ezisisiseko yenziwa kuwo, lulondolozo wayo.

Kweli nqaku siza kuqwalasela iintlobo ezisisiseko izixhobo kwakunye kwebala kwimiba efana njengendlela kunye neendlela yokugcina ulwazi.

Concept neendidi kwezixhobo

Devices Storage - olu lwazi abathwali, ogama umsebenzi kukuba ukubhala kunye data ukugcina.

Ngokumalunga computers ayikhuphi iintlobo ezimbini izixhobo - lwangaphandle nangaphakathi. Ngaphandle kunzima kunye nemagnethi disks, enombala disks, DVD kunye CD, iteyiphu drives, flash drive. Internals - le RAM kwi khompyutha yakho, inkumbulo yayo cache, BIOS, kunye iCMOs memory.

Edume kakhulu kwexesha izinto ezigcina mihla - oko uqhuba ne-flash drive. Okulandelayo siza sithethe ngazo ngokweenkcukacha uze ufumanise oko msebenzi xa uza kungena ebomini bethu.

indawo usetyenziso lweenkcukacha

Ngaphambi kokuba sithethe indlela yokujongwa lolwazi, oko kukuthi, izixhobo ezisinceda ukuba sisebenze kunye data funda iinkcazelo ebalulekileyo.

processing Ulwazi - yinto utshintsho data.

ithetha ukuba ulwazi processing kunye nokugcina - isixhobo iikhompyutha: iikhompyutha, iikhompyutha eziphathwayo, ezinceda ukufunda ukusebenza data.

Ngamanye amaxesha processing majelo ekunokuthiwa, kunye nezixhobo ezisinceda ukuba ukufunda, ukuwafunda.

Ngoko ke, lo isixhobo lokuqala idata kuqwalaselwa njengoko iibhokisi umculo kunye neegramafoni, enezikhanyiso umlingo kunye filmoskop, umatshini wokushicilela. Kamva, kukho izixhobo ezintsha, ezifana shiwe, gramophones, zikaJ, ikhamera, zeslayidi iiprojektha umboniso, oomatshini bokuchwetheza. Eqhelekileyo kuthi ke maza and iikhamera, khamera, yabavavanyi, shini nabashicileli nto inokusinceda ukuba ivelise inkcazelo.

Indlela yokugcina yokuqala

Ngoku cinga lo mbuzo, njengoko kwimbali yokugcina ulwazi ithetha. Yokwazisa liqwalasela lo mbandela, ukususela kumaxesha amandulo. Kukholelwa ukuba abathwali zokuqala iindonga emiqolombeni, leyo ezifakwe kwi-mizobo eweni. Injongo yezi mibhalo zafakwa data ukudlulisela ukuba inzala yabo. Nabo baye bathunyelwa iimbalasane wokuzingela, ubomi bentsapho, iinkolelo kunye nezinye iziganeko ezibalulekileyo. Ekuhambeni kwexesha, abantu baqalisa ukuba isetyenziselwe le njongo kufuneka amacwecwe odongwe zomkhanzi, sele abalinganiswa okanye nencwadi ebhaliweyo. Ngoko ke ixesha kunye nephepha.

Kamva kuvela njenge amakhadi ngamanqindi kwaye ngenqindi. Ngaphezu koko, phakathi kwiminyaka yoo-50 yenkulungwane lokugqibela, i tape kuza indawo kubo. Ngowe-1969, wenza idiski yokuqala floppy ukuba idabi kuphuhliso izixhobo zokugcina.

Eyona ndlela eqhelekileyo yokugcina data ngexesha lethu

Le yokugcina ulwazi imbali kuthetha ukuba sisebenzisa ngexesha lakalokunje, waqala kwisiqingatha sesibini senkulungwane lokugqibela. Eyona eyaziwa kwaye isetyenziswa kule mihla eendaba - CD- kunye DVD-ROMs nezixhobo ze-Flash-hard drive.

CD-zosasazo media yokugcina, ekhangeleka idiskhi eyenziwe ngeplastiki, embindini apho imbobo setyhula. Ukubhala kunye nokufunda lwe data lwenziwa nge laser. zisetyenziswa kakhulu ukubhala iifayile zomculo, imifanekiso kunye namaxwebhu. I-avareji ye isixhobo - 670 MB. Umhla wokuzalwa uthathwa ukuba kuwagxotha 1980. Ababhali ingcamango baba ezimbini kwiinkampani ezaziwayo-kakuhle - Philips kunye Sony.

Le DVD ifomu efanayo kunye CD. Umahluko kuphela kukuba umthamo wayo 4.5 ukuya kwi-17 GB, leyo ukugcina iifayile ezimbini imali enkulu. Ukuphuhlisa compact data, Philips ibandakanyeka ne Sony ukususela ekuqaleni-imi- 90 kwinkulungwane yokugqibela. Le yokuqala disc yakhululwa ngo-1996.

I-USB-flash drive - kwisixhobo kwakheka kwiqhezu elinye. It has a ubungakanani elincinane yomlinganiselo. isixhobo Capacitance 2 ukuya 512 GB. It ikuvumela ukugcina naziphi iifayile. Ngowe-2000 kwabonakala kunyaka data isixhobo, lophethe yokuqala-8 kuphela MB ye nkcazelo nayo. Wayila wothulelw kwinkampani Israeli M-Systems.

Hlobo luni eendaba ukukhetha?

Kakade ke, imbali izinto ezigcina iinkcukacha ikuvumela ukuba ufunde kabanzi ngazo. Okokugqibela, kukho amagama ambalwa malunga uhlobo lolwazi yenethiwekhi kakhulu. Ukuba sithethe malunga nokugcinwa kwedatha, abanobubi iinketho - ukugcina yonke into kwi PC yakho okanye kwi laptop yakho. Virus, iingxaki zobugcisa - konke oku kungabangela ukulahlekelwa inkcazelo ebalulekileyo. Ukongeza, ngokuhlaziya iintshaba ifowuni yakho entle ngokukhawuleza wazana zonke izinto zigcinwa kwimemori ye PC yakho.

indlela kakhulu ngokwezimali kwaye zithembeke - nokugcinwa kwidiski. Kodwa nantsi ukudlala kuphephe ukubhala eminye. Nangona ubu disc, ukuba ungagcina data iminyaka engaphezu kwama-10. Kulo mzekelo, sicebisa ukuba ukugcina data kuphela kwi diski ubhale-kanye.

Le ndlela yokugqibela - flash drive. Kodwa nangona ubukhulu bayo compact, abasakwazi elala neli ivuke neliya. Kuqala kwinto zonke, kwakusafuneka waseka usuku lomsebenzi drives. Okwesibini, uba sengozini yokulahlekelwa data ngokudibanisa isixhobo kwikhompyutha kunye yintsholongwane.

iziphumo

Ngoko ke, lo yokugcina ulwazi imbali kuthetha, wachaza ngokufutshane, Kuyinto umdla. Siyifumene ezinye izixhobo kuthembeka ngakumbi yaye kutheni. Sithemba ukuba le ngcaciso luncedo kuwe.
