Ifloppy diski: isakhiwo, ubuhle lobubi. Yintoni i floppy diski?

Isiqingatha abanini computer azisilindelanga nkqu ukuba kukho buchwepheshe, ezifana ushicilelo Imagnethi, kunye nesiqingatha eseleyo abasebenzisi bakholelwa ukuba eli khasethi, kubandakanywa noonondaba - floppy diski, yathi shwaka. Noko ke, ukuba sijonge kulo mba, uzakufumanisa ukuba umenzi iyaqhubeka ukuvelisa disks Imagnethi yomhlaba kunye iiteyiphu. Ngokuba yintoni? Apho kusetyenziswa ubuchwepheshe lixesha? Ugxininiso kulo nqaku - ushicilelo magnetic kwimidiya ezahlukeneyo, izinto eziluncedo nezingeloncedo kwenkulungwane technology XX.

ulwazi zembali

imithombo eendaba amaninzi abonisa ukuba disks zemagneti ithabatha indawo iiteyiphu otsalayo njenge izithuthi compact ngakumbi. Oku akuyonyani. Enyanisweni, ifloppy diski - it njengamalalela sinendawo of amakhadi. Kwaye okhuphisana tapes azikwazi kuba ngesizathu esilula - umthamo wabo incommensurable.

Ukukhutshwa wokuqala disk magnetic yenziwa yi-IBM, nto leyo 1971 wabonisa izwe ifloppy diski kunye ububanzi of intshi ezisibhozo nabanako zokurekhodisha i drive kwaye data awalese lokugcina. Umthamo we floppy disk na ikhulu kilobytes, nto leyo ngokwaneleyo ukulungiselela ukugcinwa kunye ukudluliselwa ixesha. Kwiminyaka embalwa kamva wabonakala phezu yesayizi yemakethi medium ezintlanu kunye ikota intshi, kwaye ngo-1981 iqela Sony edumileyo kuqaliswa emarikeni ifloppy diski kunye ububanzi of 3.5 intshi. Ekuqaleni, lo mqulu waba 720 ikhilobhayithi floppy diski. Kodwa kamva, ngokwandisa ushicilelo uxinano, abathwali apho kwaye 1,44 Mb 2,88 Mb.

Yaye ethetha zokurekhodisha magnetic jikelele

transfer ulwazi kwenziwa kuphela kwi floppy diski, kodwa kwakhona kwi-bhanya kunye nophethe engqongqo. Umgaqo zokurekhodisha isenzo kwi eendaba ethambileyo kuye kwafika kubo bonke.
