Kuleyo media ulwazi. umthamo Ulwazi we floppy disk

Kukho onjalo lwazi eliphakathi - ifloppy diski. umthamo Ulwazi kogcino lincinane, kwaye oku kuye kwakhokelela ekubeni ukuba alufane lusetyenziswe. Nangona kukho amathuba okuba ukuvuselela iteknoloji wathi isicelo kwezinye imigaqo eziliqela zokwakha yenethiwekhi data. Ngoku makhe sibone ukuba yintoni umthamo ulwazi ifloppy diski, xa waqalisa ukusetyenziswa nokuba yintoni ubukhulu na.

tape magnetic

Isiseko ubuchwepheshe ochazwe i tape ngemagnethi. Kuyinto ephathwayo carrier data, ezithi zibhalwe kwaye data igcinwe. tape Magnetic ise khona indawo yokuhlala ekhuselekileyo zeplastiki, nto leyo isale umaleko ferromagnetic. Ukuze ufunde idatha egcinwe kuso, kuzakusebenziswa i drive.

Kule ncwadi yasekhaya KMT shunqulelo lisetyenziswa ukubhekisela kuyo. Imela njenge "diski floppy". Yiloo nto kubaluleke kakhulu kuleyo. Inkcazelo umthamo ophethe kuxhomekeke nokudalwa zobugcisa. Kodwa masikhe sithathe yonke into ukuze.

intshi ezisibhozo

Ngoko kakhulu yaba sangqa lokuqala ifloppy diski. umthamo Ulwazi yena ngaphantsi kwe 100 KB. Development kwakubo ІVM isiqalo emva kuqaliswa ngo-1960, hard drive yayo yokuqala. imodeli yokuqala apho kwaqalisa ixesha izixhobo zokugcina eziphathwayo iye yamiselwa Ngo 1967.

Isampulu yokuqala esetyenziswa njenge inshorensi yokhuselo kunye lunenwebu ngelaphu. Emva inani elikhulu leemvavanyo, iimvavanyo kunye nezongezelelo ngo-1971, wayila sele inikezelwe kwi emarikeni. Thengisa ngoko floppy disks of intshi 8 zazisenziwa ivili iplastiki elula, leyo yambathiswa oxide ngentsimbi baze bafakwe ikhadibhodi kwisingxobo. ethile yayo ebonakalayo kukuba kukho ukulinganiselwa ezinzulu.

Kwakunxibelelene kukuba, ekuqaleni, ezifana indawo yokugcina data wadala ukuba firmware kunye software eyimfuneko lokufunyaniswa karhulumente kweenkqubo ezinkulu computer. Ukusebenzisa i drive ivumela umqhubi lweenkqubo computing electronic ngokukhawuleza ukuvelisa amanyathelo ayimfuneko. Kwafuneka nje ukuba ukulayisha iseti efanelekileyo imiyalelo waba floppy diski.

umthamo Information ngelo xesha siyicacisa ngokucacileyyo ngempumelelo ukusebenzisana kunye nekhompyutha. Kwakhona amandla ukwandisa, ngenxa yokuba lo mmandla data ekuqaleni kuphela kwelinye icala floppy diski.

Ubukhulu ngo 5.25

Wheels ngokobukhulu zaqaliswa Shugart Association ngo-1976. Ekuqaleni, umthamo wabo malunga 100 kilobytes ulwazi. Kodwa ngokuhamba kwexesha, ngoncedo iinkampani kunye neenkampani, ukhululwe abathwali kuye, nto leyo ushicilelo kabini ezimbini. Ukongeza, loxinano areal iye luphindiwe. Isiphumo yezi zazo kukuba umthamo ulwazi wakhula 1.2 MB.

Olu phuhliso luyakhuthazwa IBM, nto leyo eyakhokelela ekubeni ukusetyenziswa lwabo ngokubanzi. Ethandwa kakhulu iindidi ezintathu floppy disks:

• 160 KB;
• 360 KB;
• 12 MB.

3.5 intshi kuleyo

Eyona phambili ngalo mzuzu zesampulu zinikwe yi Sony ngasekuqaleni 1980. Kakade ke, kukho abaliqela ezahlukeneyo zokhuphiswano, kodwa IBM wayeka kwisampula 3.5 intshi. Ngowe-1984 wabekwa kwifomati floppy disks, kwakunye luvelise yenziwe ogqibeleleyo kwaye ilungiswe.

Kwakukho ezimbalwa umehluko. Phakathi kwabo - ubukho ityala iplastiki eqinileyo, kwaye uvale i window ukuba ufunde iintloko ezinokususwa valve metal. Utshintsho kule sizukulwana ye floppy disks ziye zenziwe engamashumi amabini. Kwaye ku March, 2011 ngu Sony baziswa ngokomthetho ukuba wayeza kuyeka imveliso kunye neentengiso ezi drives.

Kangangexesha elide kakhulu ukukhonza abantu kuleyo - amandla ulwazi kogcino nangona ayinkulwanga, kodwa ngaphezulu kokwanele zokugcina amaxwebhu ngeletroniki okubhaliweyo okanye spreadsheets. Nangona kusenokwenzeka, kwezinye iindawo basetyenziswa. Ngapha koko, ukuba enobulungisa ukuze athi umbhali ikhompyutha idrayivu yediski, yaye loo mntu wathi loo mazwi, ukubukela pack ayisa kusetyenziswa 3.5 dyuymovok. Kodwa ke iisampuli mihla iikhompyutha eyenziweyo kule minyaka imbalwa idlulileyo, akusekho zinako iintsimbi ukufunda kwezi abathwali.

Kutheni bayeka ukusebenzisa izinto ezigcina iinkcukacha

Esona sizathu siphambili le - umthamo omncinci iinkcukacha ezikuso (umthamo ulwazi 1,44 Mbyte floppy diski). Yena wadlala indima kunye nokuthembeka asezantsi noko. Ngoko ke, kaninzi kwenzeka kanye ukuba uwise - kunye floppy disk kuphoswa kude (kodwa asingomqathango, nje inxalenye ipateni).

Ukongeza, wavele, kukho izizathu ezininzi ezahlukeneyo ukuphanza kwayo. Abaninzi waphawula ukuba emva uhambo ukuya abathwali metro abasekho ukusebenza. Abanye bathi ukuba kwelanga kwanele (kuvela umbuzo yendalo -? Njani abemi ezinjalo Kwathi engqondweni) Okanye kubanda. Enokuthenjwa inkcazelo ukuba ifloppy diski akayithandi ukufuma, kwakunye notshintsho okubonakalayo lobushushu (nangaphandle kuluhlu kucetyiswa).

Kodwa ukuba kunjalo, ulwazi amandla ubuninzi floppy - kuphela 1,44 MB, ngoku akukho nokutsho ukuba avareji umculo ifayili enye mp3. ukusetyenziswa Ubuninzi yamanje - iseti yamaxwebhu itekisi kunye spreadsheets kunye namanani.

iimpawu

Mhlawumbi esandleni unaso floppy diski? umthamo Ulwazi ungenamdla kuthi ngoku, nje jonga kwi mingxuma ezimbini ezincinane emazantsi (iifestile). Enye kusoloko kurhulumente evulekileyo (nje ayivaleki). Kodwa yesibini engafani. Kwi oku kuxhomekeke ithuba zokurekhodisha.

Ngoko ke xa ifestile yesibini evulekileyo, oko kuthetha ukuba akukho nto ibe ifloppy diski ukurekhoda okanye ukucima ngayo. Kodwa xa ukuvula kulo, njengoko kuya kuba kunokwenzeka ngoko nangoko. Nantsi indlela kukhuseleko kukuthi, kule eendaba.

Ukuthelekisa nezinye iziphathi

Makhe achitha isishwankathelo encinane eendaba. Yintoni na umthamo wenkcazelo floppy diski, disk nzima, CD, i-DVD kunye flash-ngemoto? Uhlobo lokuqala yenethiwekhi siye ngempumelelo ziqwalaselwe.

Le disk nzima kuthiwe ukuba ngowokuqala kubo ngumqulu ulwazi olugcinwe kwi 2MB. Ngoku kunokubonwa ekuthengisweni izithuthi 3TB.

technology lemveliso CD ayikho ethembisa kakhulu, ngenxa yokuba akunakwenzeka ukuba isiphumo ezingaphezu kwama-700 MB. Kodwa xa kuthelekiswa floppy disks - oko kwaba intuthuko.

Optical DVD eendaba, njengoko umthetho, eyakhutshwa nge-4.7 GB, ngelixa abo na umsebenzi yokurekhoda endlela-mbini liyi index abangaphezu kwama-8 GB.

A yempahla data, eyakhelwe iteknoloji flash, uyakwazi ndoqhayisa isixa esikhulu indawo yokugcina kunye nobukhulu amancinci. Basenokuba kuthathwa ezimbalwa ukuya amakhulu gigabytes zolwazi. Njengoko ubona, nangona ixesha elide kakhulu, isixa data egcinwe liye landa amawaka amaxesha.
