1 mbps - noocaas ah ee xawaaraha? Si kooban oo ku saabsan gelinno iyo bytes

Shuruudaha midani xawaaraha internetka, way adag tahay in la fahmo nin ka fog ku xiran yahay. Tusaale ahaan, adeeg bixiye waxay bixisaa helitaanka Internet xawaare of 1 Mbit / s, laakiin uma baahnid inaad wax badan ama wax yar ka og. Aan fahamsanahay in this - mbps, iyo sida guud ahaan lagu qiyaasay xawaaraha khadka Internetka aad.

deciphering gaabiyey

Tarjumaadda suugaan "mbps" (Mbit per labaad) - megabits per labaad. Waa in kuwan unugyada inta badan qiyaasay xawaaraha ku-xiranka. All xawaaraha bixiyayaasha ayaa tilmaamaya in xayeysiis ay megabits per labaad, oo uu noogu ku kici in la qiimeeyo qabtaan.

Intee in leeg sameeyaa - 1 mbps?

Waayo, ku bilaabatay, 1 xoogaa waa qaybta ugu yar oo lagu qiyaaso mugga macluumaadka. On par leh garaaca ah, dadka inta badan ay isticmaalaan bytes, luxo xaqiiqda ah in labadan fikradaha waa kuwo kala duwan. Mararka qaarkood waxay yidhaahdaan, "byte", Iyadoo lagu tilmaamayo "yar", iyo qeybsanaan. Sidaa darteed waxaa lagama maarmaan ah in la tixgeliyo arrintan si faahfaahsan.

Sayidka, 1-bit - unit ugu yar ee cabbirka. 8 gelinno u dhigmaa hal byte, 16-bit - .. Laba bytes, iwm si kale loo dhigo, waxaad u baahan tahay oo kaliya in la xasuusto in byte had iyo jeer waa 8 jeer gelinno dheeraad ah.

Marka la eego in labada cutub aad u yar tahay iyaga u kiisaska intooda badan isticmaalka Horgalaha "ahee" ah, "pounds" iyo "Giga". Maxaad ula jeeddaan horgalayaasha kuwan, in aad la socoto dabcan dugsiga. Laakiin haddii aad u illoobin, hadana waxa xusuus mudan:

1. "Kilo" - dhufashada by 1 000 1 kilobit waa 1000 gelinno, 1 kilobyte waa 1024 bytes.
2. "Ahee" - dhufashada by-1 000 000. 1 megabit waa 1000 kilobits (ama 1,000,000 gaballo), 1 megabyte waa 1024 kilobayt.
3. "Giga" - dhufashada halkii 1 000 000 000 1 gigabit waa 1000 megabits (ama 1 billion gaballo), 1-ki gigabyte waa 1024 megabytes.

In erayada fudud, xawaaraha xiriir - waxaa lagu soo diray iyo xawaaraha macluumaad helay computer ka mid ah unit of time (labaad). Haddii aad sheeg xawaaraha aad internet 1 mbps, maxay ka dhigan tahay? Xaaladdan oo kale, waxay sheegtay in in xawaaraha Internet waa 1 megabit per labaad ama 1000 kbits / labaad.

Ma badan

dadka isticmaala badan ayaa waxay aaminsan yihiin in mbps - in badan. Dhab ahaantii, ma aha. shabakadaha maanta waxaa si hormartay in la awoodooda, 1 mbps - taasi waxba at dhan. Halkan waxaa ku qoran xisaabinta xawaaraha this on tusaale ee soo degsado files ka internetka.

Ka fikir in mbps - waxaa megabits per labaad. U qaybi qiimaha 1 ilaa 8 iyo hesho megabytes. Total 1/8 = 0.125 megabyte / labaad. Haddii aan rabno in download music internetka, ka dibna ka yar shardi ah in mid ka mid track, "culeyskiisu yahay" 3 megabytes (sida caadiga ah raad aad u badan oo "miisaamaan"), waxaan awoodnaa inaan ku soo dejisan in 24 ilbiriqsi noqon doonaa. Xisaabi fudud: 3 mebagayta (miisaanka mid track) waa in la kala qaybiyey 0,125 megabyte / labaad (Our xawaaraha). Result - 24 ilbiriqsi.

Laakiin tani khuseysaa oo keliya in ay gabayadii caadiga ah. Oo haddii aad rabto in aad kala soo bixi a movie, size 1.5 GB? Aynu ka fiirsan:

• 1500 (megabytes): 0,125 (megabytes per labaad) = 12 000 (seconds).

Translate ilbiriqsi daqiiqo:

• 12 000: 60 = 200 daqiiqo ama 3,33 saac.

Sidaas darteed, at 1 mbps xawaaraha internet, waxaan awoodnaa inaan ku soo bixi filim, 1.5 GB per 3,33 saac noqon doonaa. Halkan xaakinka naftaada, muddo dheer ama ma.

Marka la eego xaqiiqada ah in magaalooyinka waaweyn ISPs bixiyaan xawaare Internet ilaa 100 mbps, waxaan awoodi doonaan in ay soo bixi movie la mug isku mid ka yar 2 daqiiqo, halkii 200. Taasi waa 100 jeer ka dhakhsi. Haddii aad bilowdo ka this, waxaa la Xukumi karo in mbps - waa xawaare hoose.

Laakiin wax walba waa qaraabo. In qaar ka mid ah tuulada fog, halkaas oo ay adag tahay in la qabto xataa GSM-network, waxay leeyihiin internetka si dhakhso ah - waa qabow. Si kastaba ha ahaatee, in a Magaalooyinka waaweyn la tartan weyn uu u dhaxeeyo bixiyeyaasha adeegga iyo ka shaqeeya mobile internet saboolka ah sida ma noqon karaan.

gunaanad

Hadda oo aad ogtahay sida si loo ogaado xawaaraha internetka, iyo fahmi karo waxoogaa unugyada xogta. Dabcan, si ay lumaan iyaga oo ku - fud, laakiin waxa ugu muhimsan ayaa ah in la xusuusto waa in xoogaa - waa mid siddeedaad ee byte ah. Horgalaha A "kilo," "ahee" iyo "Giga" dar kaliya saddex, lix ama sagaal eber, siday u kala horreeyaan. Haddii ay taasi la fahamsan yahay, ka dibna wax kasta oo ku dhacaa meel.
