Incazelo yamanani amancane (Kbps, Mbps & Gbps) futhi okusheshayo
Izinga lwedatha lokuxhumeka kwenethiwekhi ngokuvamile lilinganiselwe kuma-unit of bits ngomzuzwana (bps). Abakhiqizi bemishini yenethiwekhi bayalinganisa izinga eliphezulu lokuhamba komkhawulokudonsa imikhiqizo yabo yokusekela ngokusebenzisa amayunithi ajwayelekile we-Kbps, Mbps, ne-Gbps.
Lezi zikhathi ezithile zibizwa ngokuthi amajubane e-intanethi ngoba njengoba ukukhula kwenethiwekhi kukhula, kulula ukuwaveza ezinkulungwaneni (kilo-), izigidi (mega-) noma izigidigidi (giga) zezinyunithi ngesikhathi esisodwa.
Izincazelo
Njengoba i-kilo- isho ukubiza inani eliyinkulungwane, lisetshenziselwa ukukhombisa isivinini esiphansi kunaleli qembu:
- I- kilobit eyodwa ngomzuzwana (Kbps) ilinganisa izingqikithi ezingu-1,000 ngomzuzwana (bps). Lokhu ngezinye izikhathi kubhalwe njenge-kbps, Kb / sec noma i-Kb / s kodwa zonke ziphethe incazelo efanayo.
- I-megabit ngayinye ngesigamu (Mbps) ilingana no-1000 Kbps noma i-bps eyodwa yezigidi. Kubuye kuboniswe njengoMbps, Mb / sec, no-Mb / s.
- I-gigabit eyodwa ngomzuzwana (Gbps) ilingana no-1000 Mbps, i-million Kbps noma i-bps eyodwa bps. Iphinde ifinyelelwe njengeGbps, Gb / sec, ne-Gb / s.
Ukugwema ukudideka phakathi kwamabhayithi nama-Bytes
Ngenxa yezizathu zomlando, amazinga wedatha we-disk drive kanye nezinye izinto (okungezona kwenethiwekhi) imishini ngezinye izikhathi kuboniswa ngama- bytes ngomzuzwana (Bps enomzimba ophezulu) B esikhundleni sezinsimbi ngekhondi (i-bps ene-lowercase 'b').
- I-KBps eyodwa ilingana ne-kilobyte ngomzuzwana
- I-MBps eyodwa ilinganisa i-megabyte eyodwa ngomzuzwana
- I-GBP eyodwa ilingana ne-gigabyte eyodwa ngomzuzwana
Ngenxa yokuthi i-byte eyodwa ilingana nama-bits ayisishiyagalombili, ukuguqula lezi zilinganiso kufomu elincane elihambelanayo 'b' lingenziwa ngokumane liphindwe ngo-8:
- I-KBps eyodwa ilingana no-8 Kbps
- I-MBps eyodwa ilingana no-8 Mbps
- I-GBP eyodwa ilingana no-8 Gbps
Ukuze ugweme ukudideka phakathi kwamabhithi nama-bytes, ochwepheshe be-networking bahlale bebhekisela ekuvinjeni kwenethiwekhi ngokwemibandela ye-bps (ephansi ye-'c '').
Ukulinganisa okusheshayo kwezinto ezivamile zokuxhumana
Izingosi zenethiwekhi nezilinganiso ze-Kbps esheshayo zivame ukudala nokusebenza okuphansi ngamazinga anamuhla. Ama - modemu amadala wokudayela asekela amazinga wedatha kuze kube ngu-56 Kbps, isibonelo.
Imishini eminingi yenethiwekhi ihlanganisa izilinganiso zejubane ze-Mbps.
- Ukuxhumeka kwe-intanethi yekhaya kungakhanya ukusuka kumanani aphansi njenge-1 Mbps kufika ku-100 Mbps futhi ephakeme nakakhulu
- I-802.11g Ukuxhumeka kwe-Wi-Fi Rate ku-54 Mbps
- Ukuxhumana okudala kwe- Ethernet Ukukala ku-100 Mbps
- Ukuxhumeka kwe-Wi-Fi okungu- 802.11n Ukukala ku-150 Mbps, 300 Mbps, nokunyuka okuphezulu
I-high-end gear ihlanganisa ukukala kwejubane le-Gbps:
- I-Gigabit Ethernet isekela i-1 Gbps
- Izixhumanisi ze- backbone zenethiwekhi ezondla abahlinzeki be-intanethi kanye nemibhoshongo yeselula isekela ama-Gbps amaningi
Yini ezayo emva kwe-Gbps?
I-1000 Gbps ilinganisa i-terabit elingu-1 ngomzuzwana (Tbps). Zimbalwa ubuchwepheshe be-Tbps zokuxhumana okusheshayo zikhona namuhla.
Uhlelo lwe-Inthanethi2 luye lwakha ukuxhumeka kwe-Tbps ukusekela inethiwekhi yayo yokuhlola, futhi ezinye izinkampani zemboni zibuye zakha ama-testbeds futhi zibonise ngempumelelo izixhumanisi ze-Tbps.
Ngenxa yezindleko eziphezulu zezinto zokusebenza nezinselele zokusebenzisa inethiwekhi enjalo ngokuthembekile, kulindeleke ukuthi kuyoba iminyaka eminingi ngaphambi kokuba la mazinga okuvinjelwa asebenze ngokujwayelekile.
Indlela Yokuguqulwa Kwezinga Ledatha
Kuyinto elula ngempela ukuguqula phakathi kwale miyunithi uma wazi ukuthi kunezinkinobho ezingu-8 kuzo zonke i-byte nokuthi lelo kilo, i-Mega, ne-Giga lisho izinkulungwane, izigidi nezigidigidi. Ungenza izibalo ngokwakho noma usebenzise noma iyiphi yezinombolo zokubala oku-intanethi.
Isibonelo, ungakwazi ukuguqula i-Kbps ku-Mbps ngalezo zimiso. 15,000 Kbps = 15 Mbps ngoba kunama-kilobithi angu-1,000 ku-1 megabit ngayinye.
I-CheckYourMath iyinkokhelo eyodwa esekela ukuguqulwa kwesilinganiso sedatha. Ungasebenzisa futhi i-Google, kanje.
