1 mbps - ukuba uhlobo speed? Ngokufutshane malunga naphaya bytes

Imigaqo ebonisa isantya Internet, kunzima ukuqonda umntu kude sifundo. Umzekelo, umboneleli-nkonzo ibonelela ukufikelela Internet ngesantya 1 Mbit / s, kodwa andazi kakhulu okanye kancinci. Masiqonde ukuba oku - mbps, yaye njengoko kulinganiswa ngokubanzi yi isantya sonxulumaniso lwe Internet.

ziqonde izifinyezo

Le nguqulelo yokoqobo "mbps" (Mbit ngomzuzwana) - megabits ngomzuzu. Kuyinto ngeeyunithi la Isantya uqhagamshelo kakhulu kulinganiswa. Zonke Isantya abanikezeli zibonisa kulo mhlomlo zabo megabits yesibini nganye, kwaye malini ukuba ukujongana yala maxabiso.

Yimalini does it - 1 mbps?

Ngokuba ekuqaleni, 1 bit lusisisekelo lincinane zokulinganisa umthamo ulwazi. On belingana isingqi, abantu badla ngokusebenzisa bytes, engazi lutho yokuba la magama mabini zahluke kakhulu. Maxa wambi bathi, "byte", ethetha ukuba 'kungagqibekanga ", yaye vice versa. Ngoko ke kubalulekile ukuqwalasela lo mba ngokucacileyo ngaphezulu.

Ngenxa yoko, i-bit 1 - iyunithi incinane yomlinganiselo. 8 amasuntswana ilingana byte mnye, 16-bit - .. bytes ezimbini, njl Ngamanye amazwi, kufuneka nje ukuba ukukhumbula ukuba byte isoloko amaxesha-8 amasuntswana ngaphezulu.

Sisazi ukuba zombini iiyunithi ezincinane kakhulu kuwo kwiimeko ezininzi ukusetyenziswa isimaphambili "mega", "iikhilogram" kunye "Giga". Ezi izimaphambili zithetha ntoni, kufuneka bazazi ikhosi yesikolo. Kodwa ukuba uyilibale, ukuba ukukhumbula ezixabisa:

1. "Kilo" - phinda ngo-1 000 1 ikhilobhithi 1000 amasuntswana, 1 ikhilobhayithi ngu 1024 bytes.
2. "Mega" - phinda ngo-1 000 000 1 megabit yi kilobits 1000 (okanye 1.000.000 amasuntswana), 1 imegabhayithi ngu 1024 kilobytes.
3. "Giga" - phinda-1 000 000 000 1 gigabit nganye megabits 1000 (okanye amasuntswana billion 1), 1 gigabyte ngu 1024 megabytes.

Ngamagama alula, isantya uqhagamshelwano - uthunyelwa kwaye isantya ingcaciso efunyenweyo ikhompyutha enye ngeyunithi kwexesha (okwesibini). Ukuba awukhankanyi isantya yakho uqhagamshelo intanethi 1 mbps, oko kuthetha ntoni? Kulo mzekelo, ithi ukuba isantya yakho Internet yi-1 megabit / yesibini yesibini okanye 1000 kbits nganye.

Ngaba a lot

abasebenzisi abaninzi bakholelwa ukuba mbps - ukuba okuninzi. Enyanisweni akunjalo. networks zanamhlanje zibalaseliswa phambili ukuba imisebenzi yabo, 1 mbps - loo nto konke konke. Nantsi ke kubalwe le yesantya umzekelo wokulanda iifayile kwi Internet.

Cinga ukuba mbps - it megabits ngomzuzu. Yahlula ixabiso-1 ukuya ku-8 kwaye bafumane megabytes. Iyonke 1/8 = 0.125 imegabhayithi / yesibini. Ukuba sifuna ukulayisha umculo ukusuka kwi Internet, ngoko phantsi komqathango wokuba umkhondo, "ubunzima" megabytes 3 (idla tracks kangaka yaye "inobunzima"), siya kukwazi download oko kwimizuzwana eyi-24. Bala ilula: mebagayta 3 (ubunzima lwegama enye) kufuneka yahlulwe 0,125 imegabhayithi / yesibini (isantya yethu). Isiphumo - imizuzwana 24.

Kodwa usebenza kuphela iingoma njengesiqhelo. Kwaye ukuba ufuna ukukhuphela imovie, ubungakanani 1.5 GB? Makhe sihlolisise:

• 1500 (megabytes): 0,125 (megabytes ngomzuzu) = 12 000 (kwimizuzu).

Ukuguqulela imizuzwana ngemizuzu:

• 12 000: 60 = 200 imizuzu okanye 3.33 iiyure.

Ngoko ke, ngo-1 mbps isantya-intanethi, siya kukwazi ukukhuphela imovie, ka-1.5 Gb nganye iiyure 3.33. Apha ke yicaluleni wena, ngokuba ixesha elide okanye hayi.

Ngenxa yokuba kwizixeko ezikhulu ISP zinika ngesantya Internet ukuya mbps 100, siya kukwazi ukukhuphela imovie umqulu efanayo kancinane nje kwimizuzu emi-2, endaweni 200. Loo nto izihlandlo 100 ngokukhawuleza. Ukuba uqala koku, kunokwenziwa isigqibo sokuba mbps - yinto isantya eliphantsi.

Noko ke, yonke into isihlobo. Kwezinye kwilali esemagqagaleni, apho kukho kunzima ukubamba nkqu GSM-network, babe Internet ngokukhawuleza - ukuba kupholile. Nangona kunjalo, xa sixeko enkulu kunye kukhuphiswano omkhulu phakathi abanikezeli nkonzo kunye nakwiinkampani mobile ezifana inthanethi akanakuba.

isiphelo

Ngoku uyazi ukuba ukujonga indlela isantya Internet, kwaye aqonde isuntswana iiyunithi data. Kakade ke, ukuba kulahleke kuzo - iqhekeza cake, kodwa eyona nto ibalulekileyo ukuze ukhumbule kukuba isuntswana - ukuba i wesibhozo Byte. A isimaphambili "Kilo," "musa" yaye "Giga" Faka kuphela Amaqanda ezintathu, ezintandathu okanye elithoba, ngokulandelelana. Ukuba oku kuqondwe, ngoko yonke into iwela ndawo.
