Yintoni MB nezithuthi

Umsebenzi kwikhompyutha nganye elektroniki ngokususela binary kwinkqubo inani. PC bacubungule ulwazi ngendlela yedijithali. Ngoko ke, lo matshini uyasamkela data ngokohlobo amaqanda kunye nabo. Loo maKristu abizwa ngokuba ulandelelwano lokubini (yaguqulelwa isuka bigit yokubini IsiNgesi, abasebenzisi abaninzi basebenzisa olufinyeziweyo bit).

iiyunithi ulwazi Basic. Yintoni MB?

Table ulwazi 1. Umlinganiselo Units

Amasuntswana - iyunithi esisiseko lomlinganiselo isixa kulwazi PC. Oku kunokuba ixabiso omnye okanye zero. unit Okulandelayo - byte (ezisibhozo amasuntswana serial). Ilinganisa bytes okubhaliweyo, ividiyo, imizobo. Ikhilobhayithi ulingana no-1024 bytes, 1 ikhilobhayithi iqulethe 8192 ziintanda. Yintoni MB? Ukuba iyunithi lolwazi, nto leyo ilingana ixabiso 1024 kilobytes.

kwimicimbi ngokuphathelele elithi "imegabhayithi"

Ezinye izazinzulu zikholelwa ukuba igama elithi "imegabhayithi" olungachanekanga ngokupheleleyo. Eneneni, nigweba ngegama layo, omnye imegabhayithi ukuba alingane bytes kwesigidi. Kulo mzekelo, eli candelo kufuneka igama "mebibytes". Kodwa i Cu "mega" - kuba-10 ukuya ngamandla lesithandathu, kunye megabytes kugqalwa ilingana 1.048.576 bytes.

Eli xabiso mebibytes, ilingana ezimbini ngomlinganiselo yamashumi amabini. Kuye kwaqatshelwa kwaye ngokufanayo kuphela ngo-1998. Nangona izibalo ezicacileyo zemathematika, ixabiso 1048576 bytes wababiza imegabhayithi. Nangona, enyanisweni, lo ngowona mebibytes ixabiso. Yinto kakhulu ixesha ukutshintsha icandelo data inkqubo, kuba asetyenziswa izigidi kubasebenzisi abangekho linokuva ukugwegweleza wesiseko yayo. Kodwa ukufunda eli mba, ngaphandle kwamathandabuzo, kuyimfuneko.

Kutheni abantu abaninzi kangaka umhlola ngoko yaye yintoni MB amandla iinkcukacha ezifumanekayo kuye? Kungenzeka, kwiimpazamo yokuqala zenziwa kwinkulungwane yama-20, xa kumakishwa diskettes umthamo ingxelo 1,44 MB (kunye nenkqubo C lixabiso elilinganayo 1.440.000 bytes). Kodwa enyanisweni, imali data kwezi izinto ezigcina ulingana bytes 1474560, okanye 1,474 kilobytes. Izimaphambili amaxabiso ezahlukeneyo zidityanisiwe, nto leyo amaxabiso ukuba akunakwenzeka ukuba ukubala ngokuchanekileyo. Ukuziqhelisa, umthamo ebhengeziweyo diskettes musa kunxibelelana Enyanisweni, ukuba umfutho ezi mpazamo zilandelayo ulwazi womlinganiselo. Ngoku uyazi into MB. A iiyunithi ulwazi imbali encinane iya kukunceda uqonde ngcono nezo indlela yokusebenza.

Yintoni MB "BK"?

Ngamaxesha amaninzi igama elithi "imegabhayithi" ndizigawule usebenzisa i analog - MB. Oku konga ixesha kunye nezithuthi kwi Internet. Ukongeza, isayithi "VKontakte" badla ukusebenzisa igama elithi "MB" njengendlela Lalifutshane ibinzana elithi 'inokuba ". Umzekelo, kwi ingxoxo okanye incoko elo nyathelo yenza unxibelelwano onamandla angaphezu kwaye kwakhona konga ixesha.

Traffic and megabytes: amanqaku zoqhagamshelwano

Ekubeni ilizwi IsiNgesi kwezithuthi bubonakala "yendlela". Kwicandelo lolwazi, eli gama libhekisela isixa data kwi kilobytes ukuba yamkelwe umncedisi ixesha elithile, kwaye isetyenziswa kwiinkalo ezahlukeneyo. Yeyona ingqiqo yendlela sayithi yakho, oko kukuthi, ixabiso borhwebo layo,-enjini yokukhangela izithuthi, inkcazelo ethunyelwe, njalo-njalo. D.

Alinako kuphela kulinganiswa e megabytes, kodwa gigabytes, kilobytes. Traffic ke iintlobo ezimbini:

- eziphumayo (data ukuba server uthumela);

- engenayo (imali data ifunyenwe).

Yintoni lwezithuthi (MB)? Olu isixa ingcaciso efunyenweyo okanye ithunyelwe kwisithuba ngexesha elifanayo. Ukuba ngaba awunayo Internet mda, ubalo ezendlela (oko kukuthi, i-data kwi megabytes) udinga nje. 1 MB abalinganayo, umzekelo, ukubukela amaphepha-30 kwi-Internet, kuba malunga nama-400 amaphepha itekisi kunye nemifanekiso 4-5.
