Megabit vs Megabyte - Indlela Yokuchaza Nokuguquka
I-Megabits (Mb) ne-megabytes (MB) umsindo ofanayo, futhi izifinyezo zabo zisebenzisa izinhlamvu ezifanayo, kodwa ngokuqinisekile azisho into efanayo.
Kubalulekile ukwazi ukuhlukanisa phakathi kwalababili uma ubala izinto ezifana nesivinini sokuxhumeka kwakho kwe-intanethi nobukhulu befayela noma i- hard drive .
Kusho ukuthini uma uhlola isivinini sakho se-inthanethi futhi utshele ukuthi ngu-18.20 Mbps? Kungakanani lokho ku-MB? Kuthiwani nge- flash drive ene-200 MB kwesokunxele - ngingayifunda yini kuMb uma ngifuna?
I-Little & # 34; b & # 34; I-Big & # 34; B & # 34;
I-Megabits iboniswa njenge-Mb noma i-Mbit uma ikhuluma ngesitoreji se-digital, noma i-Mbps (ama-megabits ngomzuzwana) kumongo wezinga lokudluliswa kwedatha. Konke lokhu kuboniswa nge-lowercase "b."
Isibonelo, ukuhlolwa kwejubane le- inthanethi kungalinganisa isivinini senethiwekhi yakho ku-18.20 Mbps, okusho ukuthi ama-megabits angu-18.20 adluliselwa njalo ngomzuzwana. Okuthakazelisayo ukuthi ukuhlolwa okufanayo kungasho ukuthi i-bandwidth etholakalayo ingu-2.275 MBps, noma ama-megabytes ngomzuzwana, futhi amanani asalingana.
Uma ifayili oyilanda ingu-750 MB (ama-megabytes), ngokuyisisekelo futhi u-6000 Mb (ama-megabits).
Nakhu, futhi kulula kakhulu ...
Kukhona ama-bits angu-8 ku-Byte ngayinye
Okuncane kuyinombolo yama binary noma iyunithi encane yedatha yekhompyutha. A kancane ngempela, encane kakhulu - encane kunesayizi womlingisi oyedwa ku-imeyili. Ngenxa yokulula, cabanga kancane njengokulingana komlingiswa wombhalo. Ngakho-ke, i-megabit, cishe izinhlamvu ezingu-1 ezifakiwe ezifakiwe.
Lapha lapho ifomu le- 8 bits = 1 byte lingasetshenziswa ukuguqula ama-megabithi kuma-megabytes, futhi ngokuphambene nalokho. Enye indlela yokubukeka ukuthi i-megabit ingu-1/8 we-megabyte, noma ukuthi i-megabyte izikhathi ezingu-8 ze-megabit.
Njengoba sazi ukuthi i-megabyte iphindwe kasikhombisa ukuthi inani le-megabit liyiliphi, singakwazi kalula ukuthola inani elingu-megabyte ngokuphindaphinda inombolo ye-megabit ngo-8.
Nazi ezinye izibonelo ezilula:
- Amamitha angu-8 (megabits = 1 megabyte (8 Mb = 1 MB)
- Enye (1) megabit = 1/8 megabyte = i-megabyte engu-0.125 (1Mb = 1/8 MB = 0.125 M)
Enye indlela elula yokukhumbula umehluko usayizi phakathi megabit kanye megabyte ukukhumbula nje ukuthi lapho amayunithi abo alingana (ngakho uma uqhathanisa Mb ne Mb, noma MB nge MB) inombolo megabit (Mb) kufanele ukuba inkulu (ngoba kunezinkinobho ezingu-8 ngaphakathi kwe-byte ngayinye).
Noma kunjalo, indlela esheshayo yokuthola ukuguqulwa kwe-megabit ne-megabyte ukusebenzisa i-Google. Vele useshe okuthize njengama-megabithi angu-1000 kuma-megabytes.
Qaphela: Ngisho noma i-megabyte ingama-bytes ayizigidi ezingu- 1, ukuguqulwa kusekhona "million kuya kwezigidi" kusukela kokubili "yi-megas," okusho ukuthi singasebenzisa u-8 njengenombolo yokuguqula esikhundleni sezigidi ezingu-8.
Kungani Kufanele Ukwazi Umehluko
Ukwazi ukuthi ama-megabytes empeleni ahluke kunama-megabits kubalulekile kakhulu uma usebenzisana nokuxhumeka kwakho kwe-intanethi ngoba yilokho kuphela isikhathi osibona ngisho namagagit uma kuziwa ezintweni ezihlobene nezobuchwepheshe.
Ngokwesibonelo, uma uqhathanisa ukuvinjelwa kwe-intanethi uma uthenga iphakethe le-intanethi kumhlinzeki wesevisi , ungase ufunde ukuthi i-ServiceA ingakwazi ukuletha ama-8 Mbps ne-ServiceZ inikeza 8 MBps.
Ngokubheka okusheshayo, kungase kubonakale kufana futhi ungase ukhethe nje ukuthi yini eshibhile kakhulu. Noma kunjalo, kunikezwe ukuguqulwa okuchazwe ngenhla, siyazi ukuthi i-ServiceZ ilingana nama-64 Mbps, okuyizikhathi eziyisishiyagalombili esheshayo kunesevisi:
- IsevisiA: 8 Mbps = 1 MBps
- IsevisiZ: 64 Mbps = 8 MBps
Ukukhetha isevisi eshibhile cishe kusho ukuthi uzothenga i-ServiceA, kodwa uma udinga ukushesha okusheshayo, kungenzeka ukuthi ufuna ukuthenga okubiza kakhulu. Yingakho kubalulekile ukuqaphela umehluko wabo.
Kuthiwani Nge-Gigabytes ne-Terabytes?
Lezi ezinye ezinye izinyathelo ezisetshenziselwa ukuchaza isitoreji sedatha, kodwa ziningi, zikhulu kunamagagytes. Eqinisweni, i-megabyte, engama-8 ubukhulu be-megabit, empeleni i-1/1000 ye-gigabyte ... leyo encane!
Bheka ama- Terabytes, ama-Gigabytes, nama-Petabytes: Bangaki Bakhulu? ukuze uthole olunye ulwazi.
