Sida loo turjumi bytes galay megabytes iyo dib?

Maanta our nolosha ay adag tahay in la damacsan la'aan kombiyuutarada. Waxay waxaa laga helaa meel kasta. Erayga "qayb", "byte", "megabytes" ayaa qayb ka mid ah nolosheena noqday. dadka caadiga ah inta badan u isticmaalaan iyagoo aan ogeyn waxa ay ka dhigan tahay iyo sida ay u la xidhiidhaan midba midka kale.

Gelinno, kilobits ...

Waxaa ka dhigeysa jir. Waa maxay farqiga u dhexeeya qof caadi ah oo ku takhasusay computer ah? The ugu horeysay hubiyo in mid ka mid kilobyte 1000 bytes, iyo labaad - in kilo - 1024 garaam. Oo dadkii oo caadi ah inta badan weydiiso, iyo waxa, dhab ahaantii, kaftan. Waa hagaag, waxaan u garan doonaa cagaha xaggee koraan, iyo u ogaato sida loo turjumo bytes ee megabytes ama unugyo kale oo badan.

Inyar - unit ugu yar ee macluumaadka binary. More hufan, ay tiro. Tani waxa ay tilmaamaysaa macluumaad ku saabsan mid ka mid ah labada dal ee shayga. Tusaale ahaan, signal a / signal lahayn, run / been, 1/0, iyo G. sidaas on. From magac Ingiriisi ah dhacdaa hoos bi t nary Digil ( "binary") = waxoogaa. Iyo "wax yar" waxa loola jeedaa hal lambar ee xeerka binary. Xaaladdan oo kale, god a jajab tobanle waxaa wakiil sida eber ama hal, tusaale ahaan sida ku cad miiska. Tan waxaa lagu magacaabaa "nidaamka binary of numeration."

Sida laga arki karo, tirada laga bilaabo 0 iyo 1 leeyihiin matalaad isku mid ah iyo godkee jajab tobanle waxay leedahay laba gelinno - 10. Oo siddeed - afar (1000).

Waa maxay kilobits?

The isticmaalka ugu baahsan ee nidaamka tirada this laga helay technology computer. Gaar ahaan, tirada binary loo isticmaalaa in tirada xusuus digital.

Halkan waxaa ku qoran tusaale ah. Tirada dhamaan cinwaanada suurto gal baska cinwaanka waa loo siman yahay si ay u tiro mid ka mid ah laba ka mid ah N. xad Ama haddii kale - 2 ^N. Halkan, N tusinaysaa tirada jajabka ah ee baska. Maxaan u arko? Tirada unugyada ee chip xasuusta waa loo siman yahay inay ka mid ah ama mid kale degree of 2. Ka dibna - xataa u xiiso badan. Number 2 ¹⁰ = 1024 waa mid aad u dhow 1000. Isla mar ahaantaana, kumanaan ka mid ah loo isticmaalay saldhig u horgalayaasha tobanle. Sidaas daraaddeed, 1024 gelinno ayaa loo yaqaan "kilobits". By eegtahay la garaam kilo ama kiilo mitir. Baan garwaaqsan anecdote ah, kor ku qoran.

Bytes iyo gelinno

Of computer science yaqaan sida soo socota. (Byte eng.) "Bytes" waxaa lagu magacaabaa unit kaydinta ah, iyo processing macluumaadka digital. Waxay ka dhigan tahay tirada jajabka isku mar computer baaraandego. Waa classic ah.

Nidaamyada computer Modern isticmaali byte oo ka kooban 8 gelinno. Sidaas awgeed, waxay qaadan kartaa 256 (2 ⁸⁾ qiimayaal kala duwan.

Si loogu badalo bytes in megabytes, kaliya u dhaqmaan. Xisaabta fasalka saddexaad: 1 kilobyte = 1024 bytes. Xusuusnow ku saabsan February ^10? A 1 MB = 1024 KB (m. E. 2 ^{@ 20} = ^2x10 2) = 1048576 bytes.

codsiyada

Inta badan, bytes loo isticmaalay nidaamka kombiyuutarka, iyo gelinno - in shabakadaha gudbinta xogta. Guud ahaan, waayo cabbirka xawaare.

Halkan waxaa ku qoran tusaale ah. network Ethernet bixisaa heerka xogta ah ee kala duwan ee 10 Mbit / s 1 GB / s. More in la ogaadaa in, sida caadiga ah, bytes muujinaysaa by xarafka "B" (ama Laatiin «B»). "Inyar" oo la duubay. horgalaha "kilo" lagu qorey warqad "K". Waa caasimada ah halkii ay kuwa yaryarba. A "k" yar waxa ku qoran magaca horgalaha tobanle "kilo", ie March ¹⁰ = 1000. Haddaba ka fiirsada in faahfaahin dheeraad ah su'aalaha soo socda.

horgalayaasha Binary iyo jajab tobanle

Sida loo turjumi bytes galay megabytes, ka badan ama ka yar cad. Horraantii 1999, ururka si fiican u yaqaan IEC (Commission Electrotechnical International) rido wareegga Horgalaha binary si ay u sameeyaan unugyada kala duwan ee xaddiga macluumaadka. Sababtu waxa ay ahayd tirada dhawaanshaha 1024 iyo 1000. Sidoo kale, horgalayaasha tobanle caadiga ah loo isticmaalo nidaamka SI ah, binary ku kala duwan yihiin oo keliya iyadoo la bedelayo dhawaaq la soo dhaafay ee "bi" (ka binarius Laatiin - binary). Waxa ay u muuqataa sida ku cad shaxda hoose.

Heerka ay qaateen dalal badan, laakiin magacyada galay waxaa loo isticmaalaa si joogta ah u yar, inta badan ee afka qoraal iyo - ku dhowaad marnaba. Sida loo helo sabab u cacophony ah. Waxaa laga yaabaa in sidaas. Waxaad ogolaatay in kilobits codadka gooyeen badan kibibit iyo megabytes ka khayr badan mebibytes.

Tarjumaadda bytes galay megabytes cad. Laakiin sidaas maaha oo dhan. Ilaa hadda, waxaa jira labo waji ee formation of dhufsanayaasha info. In su'aasha ka sii wareer waa sida badan waa in 1 megabyte ee bytes.

Habka ugu horeysay

.. In u horgalaha "kilo," "ahee," iwm waxaa loo isticmaalaa sida binary ah arrimaha soo socda:

• Tababaraha file iyo software kale ee goob size file ka soo gaabiyey. Tusaale ahaan barnaamijka, ayaa sheegay in size rikoorka waa 10 MB. Habka ugu classic si ay u gudbiyaan bytes in megabytes, tixgelin size ee taas la siman yahay 10485760 bytes. maamulayaasha The file of horumar dhawaan la kulmay dimensioning caadiga ah - oo isticmaaleya foom laga soo gaabiyey horgalayaasha binary, sida MiB (MiB).
• Soo-saareyaasha helaan random xasuusta, kaararka xusuusta flash, video xasuusta.
• mugga CD-ROM waxaa la siiyaa oo kaliya in megabytes binary.

Habka labaad

Halkan consoles'ka ah waxaa loo isticmaalaa sida jajab tobanle ah arrimaha soo socda:

• drives adag iyo indhaha. Hogaanka mugga in megabytes tobanle. Marka laga reebo: CD, kuwaas oo awoodda lagu tilmaamayaa in binary.
• isgaarsiinta. Xaaladdan oo kale, qiyamka qallafsan soo koobay. Tusaale ahaan, mugga of saabsan 10 milyan oo bytes of file la odhan karaa in ay tahay "culeyskiisu" 10 megabytes. Waa maxay halkan waxaan ku arki? Xaaladdan oo kale, bytes ee megabytes wareejiyo ma aha oo gebi ahaanba sax ah, laakiin xidhiidhka ka dhacayo.
• Qoondeeyey ee xawaaraha la xidhiidha isgaadhsiinta. Tusaale ahaan, waxay qaadan Heerka 100BASE-TX ah. In waxa ay 100 Mbit heerka xogta / s oo u dhiganta 100 milyan oo gaballo / s. Bal aynu eegno xarunta a more "fudutahay", iyadoo 10 Gbit / s (Heerka 10GBASE-X). Waxa u dhiganta 10 bilyan oo dhab gaballo / s. Taasi waa. Oo aan waxoogaa ka badan ama ka yar.

Laakiin saddex-inch ah saxannada kumbiyuutarka 1.44 MB (xusuuso kuwa?) Xataa u xiiso badan ahaa. awoodda ay waxaa lagu tilmaamay in ay megabytes tobanle binary-ku suntan. Waxaa la diyaariyey sida soo socota. Mid ka mid ah "megabytes" sida uu ahaa KiB waa 1000, kaas oo qiyaas ahaan 0,977 MiB, laakiin waqti isku mid ah 1 KiB barbareeyay 1024 bytes.

Waa in la ogaadaa in uu jiro farqi u dhexeeya labadan consoles'ka fursadaha soo gudbinta. Iyadoo kiiska kilobayt waxa aan ka badnayn 2.4%, ka dibna waxaa megabyte a horeba waa 4.9% in GB - 7.4%, iyo terabyte - ku dhawaad 10%. Dabcan, ma ay guushu ku matalaad ah binary. E. "xadina" our saarayaasha bytes. Tusaale ahaan, soo iibsan awood drive adag of 1 TB. Sida qof bartay cilmiga computer, aad cibaado rumeeyey inaan 1099511627776 bytes. Oo waxaa soo baxday - "kaliya" 1000000000000. Taasi waa, aad "qaniino off" in ka badan 99.5 bilyan oo bytes (ku dhowaad 98 GB). badan ama yar? Qiyaastii - min 40 ilaa 200 filim dhererka buuxa, iyada oo ku xiran qaab. Wax ku yidhi maxay ah? E., Sida kor ku qoran, meeltobnaadku.
