1 Mbps - lolo hlobo ijubane? Kafushane mayelana izingcezu kanye bytes

Imigomo elisho ijubane Inthanethi, kunzima ukuqonda umuntu kude ngendaba. Ngokwesibonelo, umnikeli wemisebenzi yezehlalakuhle inikeza ukufinyelela i-Inthanethi ngesivinini 1 Mbit / s, kepha awazi okuningi noma okuncane. Asizwise lokhu ukuthi lokhu - Mbps, futhi njengoba ngokuvamile kukalwa ijubane inthanethi.

sokuqonda izifinyezo

I kuhunyushwa "Mbps" (Mbit ngomzuzwana) - megabits ngomzuzwana. Kuyinto kulezi amayunithi avame kulinganiswa yesivinini sokuxhuma. Zonke isivinini abahlinzeki ubonise izikhangiso zabo megabits ngomzuzwana, futhi sakwenza kithi ukubhekana nalezi amagugu.

Ingakanani ke - 1 Mbps?

Okokuqala, 1 kancane kuyinto iyunithi elincane ukulinganisa umthamo kolwazi. Belingana beat, abantu ngokuvamile zisebenzisa amabhayithi, enganakile ukuthi le miqondo emibili awafani. Ngezinye izikhathi bathi, "ibhayithi", ebhekisela 'ibhithi ", futhi okuphambene nalokho. Ngakho-ke kubalulekile ukuba sinake lolu daba kabanzi.

Ngakho, i-1-bit - iyunithi kulencane angakahleleki. 8 izingcezu kulingana eyodwa ibhayithi, 16-bit - .. amabhayithi amabili, njll Ngamanye amazwi, wena nje kudingeka sikhumbule ukuthi ibhayithi uhlale ibhithi ngaphezulu kasi- 8.

Njengoba sazi ukuthi kokubili amayunithi mancane kakhulu ngabo ezimweni eziningi ukusetshenziswa isiqalo "mega", "amakhilogremu" futhi "Giga". Asho ukuthini la ticalo kusho, kufanele uqaphele inkambo esikoleni. Kodwa uma uyikhohlwa, ke ubuyisa kuwufanele:

1. "Kilo" - ukubuyabuyelela nge 1 000 1 kilobit kuyinto 1000 izingcezu, 1 kilobyte ngu-1024 bytes.
2. "Mega" - ukubuyabuyelela nge-1 000 000. 1 megabit kuyinto 1000 kilobits (noma 1,000,000 izingcezu), 1 megabyte ngu-1024 amakhilobhayithi.
3. "Giga" - ukubuyabuyelela ngayinye 1 000 000 000 1 Gigabit kuyinto 1000 megabits (noma 1 bhiliyoni izingcezu), u-1 gigabyte ngu-1024 wamamegabhayithi.

Ngamagama alula, ijubane uxhumano - lithunyelwa futhi ijubane Imininingwane wathola ikhompyutha kwelinye iyunithi isikhathi (wesibili). Uma ucacise ijubane kwakho ku-inthanethi 1 Mbps, kusho ukuthini? Kulokhu, lithi ijubane lakho Inthanethi 1 megabit ngesekhondi noma 1000 kbits / yesibili.

Ingabe okuningi

Abasebenzisi abaningi bakholelwa ukuthi Mbps - lokho okuningi. Empeleni akunjalo. amanethiwekhi zanamuhla ngakho isihambile ukuthi nge amakhono abo, 1 Mbps - ukuthi lutho nhlobo. Nangu ekubalweni leli jubane ku isibonelo ukulanda amafayela kusuka ku-intanethi.

Cabanga ukuthi Mbps - ke megabits ngomzuzwana. Hlukanisa inani 1 kuya ku-8 futhi ukuthola wamamegabhayithi. Ubude 1/8 = 0.125 megabyte / yesibili. Uma sifuna ukulanda umculo kusuka ku-intanethi, bese ngaphansi kombandela wokuthi omunye ithrekhi, "ukala" wamamegabhayithi 3 (ngokuvamile ilandelela lokungapheleli okunengi kangaka, "nesisindo"), siyokwazi ukulanda ngemizuzwana 24. Bala elula: 3 mebagayta (isisindo ithrekhi eyodwa) kufanele ihlukaniswe 0,125 megabyte / yesibili (isivinini yethu). Umphumela - 24 amasekhondi.

Kodwa lokhu kwenzeka kuphela kubantu izingoma evamile. Futhi uma ufuna ukulanda i-movie, usayizi 1.5 GB? Ake sicabangele:

• 1500 (wamamegabhayithi): 0,125 (wamamegabhayithi ngomzuzwana) = 12 000 (amasekhondi).

Humusha imizuzwana kumaminithi:

• 12 000: 60 = 200 imizuzu noma 3,33 amahora.

Ngakho, ngo-1 Mbps ngesivinini internet, siyokwazi ukulanda i-movie, 1.5 GB ngayinye amahora 3,33. Lapha ijaji ngokwakho, isikhathi eside noma cha.

Sikhishwe yokuthi izindawo zemihlangano emadolobheni amakhulu ama-ISP ukunikela ngesivinini Inthanethi kuze kube Mbps 100, besiyokwazi ukulanda movie ne ivolumu efanayo kancane njengoba imizuzu 2, esikhundleni 200. Lokho ngokushesha izikhathi 100. Uma uqala kusuka lokhu, kumele kuphetfwe ukuthi Mbps - isivinini ongaphakeme.

Nokho, konke kuxhomeke embonweni womuntu. Kwezinye indawo esemaphandleni akude, lapho kukhona nzima ukubamba ngisho GSM-inethiwekhi, babe-Inthanethi ngakho okusheshayo - kukuhle. Nokho, muzi omkhulu ne umncintiswano omkhulu phakathi abahlinzeka ngemisebenzi kanye opharetha mobile ezifana abampofu noxhumano lwe-Inthanethi akukwazi.

isiphetho

Manje ngoba sewuyazi ukuthi indlela lunquma isivinini i-Inthanethi, futhi baqonda kancane amayunithi idatha. Yiqiniso, ukuba ulahleke kuzo - ucezu ikhekhe, kodwa Into esemqoka okufanele uyikhumbule wukuthi kancane - kungcono yesishiyagalombili ibhayithi. A Isiqalo "ikhilo," "mega" futhi "Giga" engeza kuphela amaqanda amathathu, ayisithupha noma eziyisishiyagalolunye, ngokulandelana. Uma lokhu waqonda ke konke uwela indawo.
