Computer network kev ua tau zoo-qee zaus hu ua internet ceev - feem ntau ntsuas hauv units ntawm cov khoom ib ob (bps). Qhov kom muaj nuj nqis no tuaj yeem sawv cev rau tus nqi ntawm cov ntaub ntawv tiag tiag lossis qhov kev txwv theoretical rau muaj bandwidth network.
Kev piav qhia ntawm Cov Cai Ua Haujlwm
Cov tes hauj lwm niaj hnub txhawb nqa cov lej loj ntawm cov khoom ib ob. Hloov ntawm kev hais nrawm ntawm 10, 000 lossis 100, 000 bps, cov tes hauj lwm nquag nthuav tawm ib qho kev ua haujlwm thib ob raws li kilobits (Kbps), megabits (Mbps), thiab gigabits (Gbps), qhov twg:
- 1 Kbps=1,000 khoom ib ob
- 1 Mbps=1,000 Kbps
- 1 Gbps=1,000 Mbps
Ib lub network nrog qhov ua tau zoo ntawm chav nyob hauv Gbps yog nrawm dua li ib qho ntsuas hauv units ntawm Mbps lossis Kbps.
Piv txwv ntawm Kev Ntsuas Kev Ntsuas Network
Cov khoom siv network feem ntau nyob hauv Kbps yog qhov qub thiab ua haujlwm qis los ntawm cov qauv niaj hnub no.
Cov hauv qab no yog qee qhov nrawm thiab muaj peev xwm piv txwv:
- Dial-up modems txhawb kev sib kis mus txog 56 Kbps.
- Tsoom Fwv Teb Chaws Kev Sib Txuas Lus Commission xav kom muaj kev sib txuas hauv internet broadband kom muaj kev rub ceev tsawg kawg 25 Mbps thiab upload ceev tsawg kawg 3 Mbps.
- Kev ceev ceev hauv lub tsev network siv 802.11g Wi-Fi router yog ntsuas ntawm 54 Mbps, thaum tshiab 802.11n thiab 802.11ac routers raug ntsuas ntawm 450 Mbps thiab 1300 Mbps, raws li. Ib qho 802.11 ax (Wi-Fi 6) router maxes tawm ntawm 10 Gbps.
- Gigabit Ethernet hauv ib lub chaw ua haujlwm muaj tus nqi sib kis mus txog 1 Gbps.
- Ib tus neeg muab kev pabcuam fiber-optic feem ntau ncav cuag qhov nrawm ntawm 1,000 Mbps.
Bits vs. Bytes
Cov lus pom zoo siv los ntsuas lub peev xwm ntawm lub khoos phis tawj disks thiab lub cim xeeb tshwm sim zoo ib yam thaum xub thawj cov siv rau kev sib txuas-tab sis tsis txhob cuam tshuam cov khoom thiab bytes.
Cov ntaub ntawv khaws cia muaj peev xwm feem ntau ntsuas hauv units ntawm kilobytes, megabytes, thiab gigabytes. Hauv qhov kev siv tsis yog network no, tus ntawv loj K sawv cev rau qhov sib npaug ntawm 1, 024 units ntawm lub peev xwm.
Cov kab zauv hauv qab no txhais cov lej tom qab cov ntsiab lus no:
- 1 KB=1,024 bytes
- 1 MB=1,024 KB
- 1 GB=1,024 MB
