Imininingwane abezindaba engikubhalile ngikukopishe kuleyo ncwadi. umthamo sokwazisa iflophidiski

Kukhona ezifana i osebenzelana ulwazi - iflophidiski. Imininingwane umthamo kwisitoreji incane, futhi lokhu kuye kwaholela eqinisweni ukuthi kuyaqabukela esetshenziswa. Nakuba zikhona amathuba ukuvuselelwa ubuchwepheshe okushiwo isicelo yezinye izimiso eziningana ukwakhiwa esiphathiswa idatha. Manje ake sibone ukuthi yiluphi ulwazi besikhundla iflophidiski, lapho zaqala ukusetshenziswa futhi yini sayizi.

tape kazibuthe

Ngesisekelo ubuchwepheshe echazwe kuyinto itheyiphu kazibuthe. Kuyinto ephathekayo edatha enkampani yenethiwekhi, ezilotshwe futhi idatha egcinwe. tape Magnetic itholakala endaweni imizi evikelekile plastic, elibuye camera nge ungqimba ferromagnetic. Ukuze ufunde idatha elondolozwe kuyo, idrayivu isetshenziswa.

Esikhathini izincwadi yasekhaya KMT isifinyezo lisetshenziswa ekubhekiseleni kuyo. Limi njengomthombo "iflophidiski". Yilokho kusala a engikubhalile ngikukopishe kuleyo ncwadi. Umthamo inani esiphathiswa incike ukudalwa ubuchwepheshe. Kodwa ake konke ukuze.

amayintshi ayisishiyagalombili

Ngakho kakhulu-ke kwadingeka ububanzi kudiski lokuqala idrayivu. umthamo Imininingwane eseneminyaka esingaphansi 100 KB. Kutfutfukiswa ІVM inkampani yabo isiqalo emva yethulwa ngo 1960, drive walo wokuqala kanzima. imodeli kuqala ngawo kwaqalisa isikhathi amadivayisi esiphathekayo usumisiwe ngu 1967.

Isampula lokuqala lalisetshenziswa njengesibhedlela ikhava zokuzivikela nge ulwelwesi Indwangu. Ngemva inqwaba izivivinyo, ukuhlolwa kanye nokwengezwa ngo-1971, lo mshini seyenziwe emakethe. Thengisa bese amadiski floppy 8 amayintshi ayenziwa ngesikhumba isondo elula plastic, okuyinto laligcwele yensimbi oxide futhi ibekwe endaweni emikhonweni amakhadibhodi. ethile yayo enkulu bekulokhu ukuthi kukhona ezisilinganiselayo.

Kwakuhlangene yokuthi, ekuqaleni, ezifana izimpahla idatha esidalelwe firmware nesofthiwe ezidingekile sitholakele isimo izinhlelo ezinkulu ikhompyutha. Ukusebenzisa idrayivu ivumela opharetha ne-computing system electronic ngokushesha ukukhiqiza izenzo ezidingekayo. Kwakudingekile ukulayisha iqoqo esifanele imiyalelo waba iflophidiski kuphela.

umthamo Imininingwane ngaleso sikhathi kwenza kube uxhumana ngempela ngempumelelo ngekhompyutha. Iyona futhi eyayikhipha isinqumo ezingaba ukwandisa, ngenxa yokuthi endaweni idatha wayedabuka kuphela ohlangothini olulodwa iflophidiski.

Usayizi e 5.25

Amasondo nosayizi kwangena Shugart Association ngo-1976. Ekuqaleni, ivolumu yabo kwaba-100 amakhilobhayithi kolwazi. Kodwa ngokuhamba kwesikhathi, ngosizo corporations kanye nezinkampani, abathwali sebededeliwe, owawungumnyaka ukuqoshwa amabili emaceleni. Ngaphezu kwalokho, ukuminyana bhalobasar onek iye kabili. Umphumela wale manipulations wukuthi ivolumu kolwazi lakhula lafinyelela ku-1.2 MB.

Lesi senzakalo sibizwa iqhutshelwe phambili IBM, okwaholela ukusetshenziswa kwabo kwandile. Ethandwa kakhulu ayemathathu izinhlobo amadiski floppy:

• 160 KB;
• 360 KB;
• 12 MB.

3.5 intshi engikubhalile ngikukopishe kuleyo ncwadi

I isihambile kakhulu okwamanje amasampula yayenziwa ngu-Sony ngasekuqaleni 1980. Yiqiniso, baningana iminikelo ambalwa yokuncintisana ahlukahlukene, kodwa IBM wayeka ku isampula 3.5 amayintshi. Ngo-1984 wabekwa format amadiski floppy, kanye kukhicite okusungulile neliphelele ngokwengeziwe futhi ilungiswe.

Kwakukhona umehluko ezimbalwa eziyisisekelo. Phakathi kwabo - khona icala kanzima epulasitiki kanye uvala iwindi ukufunda amakhanda ezithathekayo valve metal. Izinguquko kulesi sizukulwane amadiski floppy eziye zenziwa emashumini amabili eminyaka. Futhi ngo-March 2011-Sony baziswa ngokomthetho ukuthi ayezivala ukukhiqizwa futhi yokuthengisa yalezi oshayelayo.

Kwaphela isikhathi eside kakhulu ukukhonza abantu engikubhalile ngikukopishe kuleyo ncwadi - amandla Imininingwane kwisitoreji nakuba kwakungelona ezinkulu, kodwa ngaphezu kokwanele isitoreji amadokhumenti wombhalo ngogesi noma ama-spreadsheet. Nakuba kungenzeka, kwezinye izindawo zisasetshenziswa. Phela, kuyafaneleka ukusho ukuthi umbhali has a computer yeflophidiski, futhi umuntu ukuthi ebhala lawo mazwi, ukubukela iphakethe ayisasetshenziswa 3.5 dyuymovok. Kodwa amasampula yesimanje lwamakhompyutha ekhiqizwa kule minyaka embalwa edlule, akusadingeki amakhono hardware sokufundela zinkampani zenethiwekhi.

Kungani Tashiya ezigcina

Isizathu esikhulu salokhu - nomqulu omncane kolwazi egcinwe (ulwazi umthamo 1,44 Mbyte iflophidiski). Waba nendima kanye nokwethenjelwa sasivumela ongaphakeme. Ngakho, kaningi kwake kwenzeka ukuze udedele - kanye iflophidiski kungenziwa kude aphonswe (kodwa hhayi umthetho, kuphela ingxenye iphethini).

Ngaphezu kwalokho, mhlawumbe, ukuthi kunezimbangela eziningi yokwehluleka ezahlukene. Abaningi ngaphawula ukuthi ngemva uhambo abathwali kaMasipala ayekile ukusebenza. Abanye wagomela ukuthi kwaba kwelanga okwanele (lapho kuphakama umbuzo yemvelo -? Kanjani izakhamuzi anjalo Kwathi khumbulani) Noma kubanda. Esinokwethenjelwa ulwazi ukuthi iflophidiski akawuthandi umswakama, kanye izinguquko eziphawulekayo lokushisa (nangaphandle senhlobo kunconyiwe).

Kodwa noma ngabe kunjalo, amandla ulwazi esiphezulu idrayivu - 1,44 kuphela MB, okuyinto manje ngisho ngokwanele ukuze uthole eyodwa isilinganiso ifayela umculo mp3. ukusetshenziswa enkulu yama yesimanje - iqoqo imibhalo umbhalo kanye ngamasipredishithi izibalo.

Izici

Mhlawumbe ngakwesokunene une iflophidiski? umthamo Imininingwane akusho yini esiyithandayo manje, nje sibheke izimbobo ezimbili ezincane ezansi (amafasitela). Omunye njalo in the state evulekile (kuvele akusho ukuvala). Kodwa yesibili singase sehluke. Kuleli kuncike kungenzeka ukurekhoda.

Ngakho lapho iwindi yesibili ivuliwe, kusho ukuthi akukho lutho kungaba kwi iflophidiski ukurekhoda noma uyisule. Kodwa ukuba umuntu amane nje uyivule, njengoba sizokwazi ngokushesha. Nayi indlela yezokuphepha, kulezi abezindaba.

Ukuqhathanisa nezinye zenethiwekhi

Ake ukuchitha umbono kancane abezindaba. Uyini umthamo sokwazisa iflophidiski, idrayivu kanzima, i-CD, i-DVD kanye flash-ngemoto? Uhlobo lokuqala yenethiwekhi siye ngempumelelo kubhekwe.

I disk kanzima kungashiwo ukuthi owokuqala babo has a ivolumu ulwazi egciniwe ku 2MB. Manje-ke kungabonakala ukudayiswa izimoto ukuze 3TB.

CD yokukhiqiza ubuchwepheshe akuyona ethembisa kakhulu, ngoba kwakungenakwenzeka ukuba uthole umphumela ezingaphezu kuka-700 MB. Kodwa uma kuqhathaniswa amadiski floppy - kwaba intuthuko.

Optical DVD abezindaba, njengoba umthetho, ekhishwe ku 4.7 GB, kuyilapho labo elinendawo umsebenzi ezimbili indlela yokuqopha kungaba ozibongayo Inkomba ezingaphezu kuka-8 GB.

A izimpahla idatha, eyakhelwe flash ubuchwepheshe, ungakwazi ukuziqhayisa esibalulekile sokulondoloza kanye nosayizi esincane. Zingase lisuswe ambalwa amakhulu gigabytes kolwazi. Njengoba ubona, nakuba kwakungelona isikhathi eside kakhulu, inani idatha egcinwe liye landa izikhathi eziyizinkulungwane.
