Broadband Internet. High-speed Internet

Nrog rau txoj kev loj hlob ntawm nws-technologies nyob rau hauv Internet tau ua ib tug ntau dua kev thov, yog li muaj ib tug xav tau rau txoj kev tshiab ntawm kev twb kev txuas, uas tau los ua tus broadband Internet. Nrog lub advent ntawm high-ceev Internet cov neeg siv muaj ntau txuj nrog tsawg heev dag zog.

Yuav ua li cas yog ib tug broadband Internet?

Muaj ntau cov neeg siv ntawm lub network, ntawm chav kawm, yuav tsum tau ib tug yuav tsum tau rau high-ceev thiab high-zoo kev sib txuas lus, thiab zoo tshaj plaws ntawm tag nrho cov, thiab tsis muaj-txwv. Txhua avid qhua ntawm lub Internet kev npau suav ntawm unlimited bandwidth thiab tau rau ib tug me me nqi kom tau cov ntaub ntawv koj xav tau.

Broadband yuav tau raws li tag nrho cov kev xav tau ntawm Internet cov neeg siv, nws yog tsim los muab kev nkag tau mus rau lub network thiab yog nquag siv los ntawm qhov kev pab kho mob, tswv ntawm tus IP-telephony, mobile sib txuas lus thiab lwm cov koom haum.

Broadband Internet tsis tau tsuas yog implies tau ntawm kev nkag tau mus rau lub network ntawm kev kub ceev, tab sis kuj cov kev hloov ntawm cov ntaub ntawv los ntawm lub computer. Qhov no muaj ib tug siv sib txawv los ntawm hauv Internet uas siv ib tug modem. Xeem hauj lwm nyob rau hauv lub hauv paus ntsiab lus ntawm cov neeg yuav kab thiab muaj qhia tsawg hauv lub hloov lwm lub tsev ntawm 56 kbit / s. BBA yog 40 lub sij hawm zoo tshaj - txog li 2 Mbit / s.

Cov kev pab cuam ntawm Broadband

Ntau ntev los no, hu-up nkag siv ib modem thiab ib tug xov tooj kab yog tus thawj txoj kev txuas mus rau hauv internet. Tab sis hu-up saib twb outdated, vim hais tias thaiv cov hlab lub xov tooj kab, uas yog tsis ib txwm yooj yim. High-speed Internet yog deprived ntawm no drawback, raws li nws tsis cuam tshuam rau txoj kab.

Lub ntsiab kom zoo dua ntawm broadband, high-ceev cov ntaub ntawv kis tau tus mob nyob rau hauv tas li ntawd, ib tug ruaj khov kev twb kev txuas nrog lub network thiab tau "bidirectional sib txuas lus", uas tau txais thiab xa cov ntaub ntawv ntawm kev kub ceev nyob rau hauv ob qho tib si qhia.

Cov kws kho mob raws li Broadband thiab DSL yuav muab siv ib cov xov tooj, hom no txawm tso cai rau koj los mus txhim kho cov kev ceev ntawm lub Internet, tab sis nws yog raws li nyob rau kev siv tib lub xov tooj txoj kab nrog tooj liab nyob ntawm tej. Nws zoo dua yog lus dag xwb nyob rau hauv thaum uas tig mus lag luam los ntawm telephony thiab hauv Internet.

Broadband Internet technology raws li nyob rau kev siv ntawm fiber-optic cable, uas ua hauj lwm pab ib myriad ntawm lwm yam kev khiav dej num, thiab satellite kev sib txuas lus. Niaj hnub no nws yog lub feem ntau pheej thiab txhim khu kev qha txoj kev uas yuav hloov cov ntaub ntawv.

Cov kev kab ntsab ntawm kev kub ceev hauv internet

Muaj lub sij hawm kom muaj lub Internet neeg siv yuav tau txais thiab kis cov ntaub ntawv sib txawv ntawm cov ntsiab lus ntawm kev kub ceev ua lub neej yooj yim dua.
