Cov ntaub ntawv xov xwm diskette. Cov ntaub ntawv muaj peev xwm ntawm ib tug muag nthas disk

Muaj xws li ib tug ntaub ntawv nruab nrab - muag nthas disk. Cov ntaub ntawv muaj peev xwm ntawm cov cia yog me me, thiab qhov no tau coj mus rau lub fact tias nws yog kog puas siv tau. Txawm hais tias muaj zeem muag rau lub rooj txhawb siab ntawm lub hais tias technology nyob rau hauv daim ntawv thov ntawm ob peb lwm tej ntsiab cai ntawm kev tsim kho ntawm cov ntaub ntawv cab kuj. Tam sim no cia tus paub dab tsi ntaub ntawv muaj peev xwm nyob rau hauv muag nthas disk, thaum nws pib mus rau yuav siv tau thiab yog dab tsi loj yog.

magnetic daim kab xev

Lub hauv paus ntawm lub piav technology yog ib tug sib nqus daim kab xev. Nws yog ib tug portable cov ntaub ntawv cab kuj, uas yog sau tseg thiab tej ntaub ntawv yog khaws cia. Sib Nqus daim kab xev yog nyob rau hauv ib tug ruaj ntseg yas vaj tse, uas ntxiv coated nrog ib tug ferromagnetic txheej. Yog xav nyeem cov ntaub ntawv khaws tseg rau nws, tus tsav yog siv.

Nyob rau hauv lub domestic ntaub ntawv KMT tsiaj ntawv yog siv rau xa mus rau nws. Nws sawv raws li ib tug "muag nthas disk". Hais tias yog dab tsi no yeej tseem zoo ib diskette. Cov ntaub ntawv muaj peev xwm ntawm cov cab kuj nyob rau hauv lub creation ntawm technology. Tab sis cia wb mus txhua yam nyob rau hauv kev txiav txim.

yim nti

Yog li ntawd ntau npaum li cas nws muaj ib lub cheeb ntawm cov thawj muag nthas disk. Cov ntaub ntawv muaj peev xwm nws yog tsawg tshaj li 100 KB. Kev loj hlob ntawm lawv pib ІVM lub tuam txhab tom qab nkag tau rau hauv 1960, nws cov thawj nyuaj tsav. thawj qauv uas pib lub era ntawm portable cia li tau tsim muaj Los ntawm 1967.

Tus thawj qauv siv raws li ib tug tiv thaiv cover nrog ib tug ntaub hauv ob sab phlu. Tom qab ib tug loj tus naj npawb ntawm kev ntsuam xyuas, kev ntsuam xyuas thiab ntxiv nyob rau hauv 1971, tus tsim muaj tau tau nyob rau hauv kev ua lag luam. Muag ces muag nthas disks ntawm 8 nti tau ua los ntawm tej yam yooj yim yas log, uas yog them nrog hlau oxide thiab muab tso rau hauv ib tug duab los qhia lub tes tsho. Nws tseem ceeb drawback tau hais tias muaj yeej loj heev cov kev txwv.

Nws twb kev cob cog rua nrog lub fact tias, chiv, xws li ib tug cov ntaub ntawv warehouse tsim rau firmware thiab software tsim nyog rau qhov mob ntawm lub xeev ntawm loj computer systems. Siv cov tsav tso cai rau lub teb xov tooj ntawm hluav taws xob xam tshuab los sai sai tsim tus tsim nyog ua. Nws yog tsim nyog xwb los ntsaws rau qhov tsim nyog set ntawm cov lus qhia uas muaj ib tug muag nthas disk.

Cov ntaub ntawv muaj peev xwm nyob rau ntawm lub sij hawm ua rau nws heev zoo nrog ib tug computer. Nws kuj muaj lub peev xwm mus kom, vim lub fact tias cov ntaub ntawv cheeb tsam yog Ameslikas tsuas yog nyob rau ib sab ntawm lub muag nthas disk.

Loj nyob rau hauv 5,25

Log nrog loj tau ua tswvcuab Shugart Association nyob rau hauv 1976. Chiv, lawv ntim yog hais txog 100 kilobytes ntawm cov ntaub ntawv. Tab sis thaum lub sij hawm, nrog rau cov kev pab los ntawm corporations thiab tuam txhab uas muag, muaj tau raug tso tawm, uas yog ob tug mog cov ntaubntawv povthawj siv. Nyob rau hauv tas li ntawd, lub areal ceev tau ob npaug. Cov tshwm sim ntawm cov manipulations yog hais tias lub ntim ntawm cov ntaub ntawv loj hlob los mus 1.2 MB.

Qhov no txoj kev loj hlob yog nquag nce IBM, uas coj mus rau lawv ntau siv. Cov feem nrov peb hom muag nthas disks:

• 160 KB;
• 360 KB;
• 12 MB.

3.5 nti diskette

Qhov tseem paub ntau thaum lub caij qhov kev kuaj twb muaj los ntawm Sony nyob rau hauv thaum ntxov 1980s. Ntawm cov hoob kawm, muaj ib tug heev ob peb ntau yam kev sib tw offerings, tab sis IBM nres rau ntawm ib tug qauv ntawm 3.5 nti. Nyob rau hauv 1984 nws twb teem hom muag nthas disks, raws li zoo raws li tsim ib tug ntau zoo meej thiab hloov invention.

Muaj ib tug ob peb yam tseem ceeb sib txawv. Cov lawv - lub xub ntiag ntawm ib tug nyuaj yas rooj plaub, thiab kaw lub qhov rais nyeem hau rooj noj hlau valve. Kev hloov mus rau tiam no ntawm muag nthas disks tau ua rau ob lub decades. Thiab nyob rau hauv lub peb hlis ntuj, 2011 los ntawm Sony officially tshaj tawm hais tias lawv yuav tso tseg lawm thiab muag khoom ntawm cov drives.

Rau ib tug ntev heev lub sij hawm ua hauj lwm rau cov neeg diskette - cov ntaub ntawv muaj peev xwm ntawm cov cia txawm hais tias nws tsis yog loj, tab sis nws yog ntau tshaj li txaus rau lub cia ntawm hluav taws xob hauv cov ntawv nyeem cov ntaub ntawv los yog spreadsheets. Txawm hais tias nws yog yuav, nyob rau hauv ib txhia qhov chaw lawv tseem siv. Tom qab tag nrho, nws yog kev ncaj ncees hais tias tus sau muaj ib tug computer disk drive, thiab mus rau tus neeg uas sau cov lus ntawd, saib ib pob yog tsis siv 3.5 dyuymovok. Tab sis cov niaj hnub kuaj ntawm computers manufactured nyob rau hauv qhov kawg ob peb xyoos, tsis muaj tus kho vajtse tuition ntawm nyeem ntawv nrog cov muaj.

Yog vim li cas tso lub cia xov xwm

Lub ntsiab yog vim li cas rau qhov no - ib tug me me volume ntawm muab cov lus qhia (ntaub ntawv muaj peev xwm yog 1,44 Mbyte muag nthas disk). Nws ua si ib lub luag hauj lwm thiab ib tug ncaj uas tsis muaj kev ntseeg. Yog li ntawd, feem ntau heev nws tshwm sim ib zaug ua poob - thiab ib tug muag nthas disk yuav muab pov tseg (tab sis nws tsis yog ib tug txoj cai, tsuas yog ib feem ntawm tus qauv).

Nyob rau hauv tas li ntawd, txawm, muaj ntau ntau yam sib txawv ua rau nws tsis ua hauj lwm. Muaj ntau pom hais tias tom qab ib qho chaw twg mus rau lub xov nqa tau ceased mus ua hauj lwm. Lwm tus sib cav hais tias nws yog txaus tshav ntuj (muaj tshwm sim ib yam lo lus nug - yuav ua li cas xws pej xeem nws tuaj mus mloog?) Los yog huab cua txias. Txhim khu kev qha yog cov ntaub ntawv uas cov muag nthas disk tsis nyiam dej, raws li zoo raws li tseem ceeb kev hloov nyob rau hauv kub (thiab tawm ntawm lub pom zoo ntau yam).

Tab sis yog hais tias raws li nws yuav ua tau, cov ntaub ntawv muaj peev xwm ntawm muag nthas tshaj plaws - tsuas yog 1,44 MB, uas yog tam sim no tsis txaus txawm mus yuav tau ib tug nruab nrab music ntaub ntawv rau mp3. Maximum siv niaj hnub - ib tug txheej ntawm ntawv nyeem cov ntaub ntawv thiab spreadsheets uas muaj nuj nqis.

nta

Tej zaum rau ntawm txhais tes koj muaj ib tug muag nthas disk? Cov ntaub ntawv muaj peev xwm tsis nyiam peb tam sim no, cia li coj ib tug saib lub ob tug me me qhov nyob rau hauv qab (lub qhov rais). Ib tug yog ib txwm nyob rau hauv lub qhib hauv lub xeev (nws tsuas tsis kaw). Tab sis lub thib ob tej zaum yuav zoo sib txawv. Nyob rau qhov no nyob rau hauv lub tau ntawm cov ntaubntawv povthawj siv.

Yog li ntawd thaum lub thib ob lub qhov rais qhib, nws txhais tau tias tsis muaj dab tsi yuav ua tau rau ib tug muag nthas disk rau sau los yog lwv nws. Tab sis ib tug muaj tsuas mus qhib nws, raws li nws yuav tsum tau sai li sai tau. Ntawm no yog ib tug muaj kev ruaj ntseg mechanism yog, nyob rau hauv cov xov xwm.

Kev sib piv nrog lwm yam muaj

Wb siv ib tug me ntsis txheej txheem cej luam ntawm cov xov xwm. Yuav ua li cas yog cov ntaub ntawv muaj peev xwm ntawm ib tug muag nthas disk, hard disk, CD, DVD thiab flash-drives? Tus thawj hom cab kuj peb tau ntse tau saib.

Lub hard disk yuav hais tias tus thawj ntawm lawv muaj ib tug ntim ntawm cov ntaub ntawv khaws tseg nyob rau hauv lub 2MB. Tam sim no nws yuav pom nyob rau hauv lub qhov muag ntawm tsheb 3TB.

CD raug technology yog tsis heev pheej, vim hais tias nws twb tsis tau kom tau qhov tshwm sim los ntawm ntau tshaj 700 MB. Tab sis yog muab piv rau muag nthas disks - nws yog ib tug txhob.

Kho qhov muag DVD xov xwm, raws li ib tug txoj cai, muab rau 4.7 GB, thaum cov neeg uas muaj ib tug muaj nuj nqi ntawm ob-txoj kev cov ntaubntawv povthawj siv yuav khav index ntawm ntau tshaj 8 GB.

Ib tug cov ntaub ntawv warehouse, ua rau flash technology, yuav khav ntawm ib tug tseem ceeb npaum li cas ntawm qhov chaw cia thiab loj me me. Tej zaum lawv yuav tau coj los ntawm ib tug ob peb mus rau pua pua ntawm gigabytes ntawm cov ntaub ntawv. Raws li koj tau pom, txawm hais tias nws tsis yog ib tug ntev heev lub sij hawm, tus nqi ntawm cov ntaub ntawv khaws tseg muaj ntau zog txhiab ntawm lub sij hawm.
