Liwiro pazipita Intaneti, anapereka mkati zamakono

Mmodzi wa mafunso yooneka ngati yosavuta, limene palibe yankho okhazikika motere: "Kodi liwiro pazipita digito kuwombola deta pakati pa makompyuta awiri?" Mwachitsanzo, amadziwika kuti mu chimango cha njira Japanese wa kutengerapo experimental deta wakhala anachita pakati pa kompyuta imathamanga terabytes oposa awiri pa mphindi (20 terabits pa 2012). Komabe, mtengo wa ndikukhazikitsa njira amenewa ndi okwera kwambiri, zomwe si kupanga TV sayansi. Chotero ubwino ndi gawo la kachitidwe apadera kompyuta ndi maukonde zida prototypes. Wamba eni kompyuta ndi chidwi ndi funso zimene liwiro pazipita Intaneti, akufuna njira imodzi kapena Wopereka wina.

muyenera

Voliyumu ya phukusi ano mapulogalamu ndi owona matumizidwe ophatikizika amawu, nyimbo ndi zithunzi ndi modetsa zosaneneka. Mwachitsanzo, ngati kufalitsidwa kwa kudziwika Windows XP opaleshoni dongosolo aikidwa pa muyezo 700MB CD, Mabaibulo wotsatira amafuna DVD (pang'ono kapena kwathunthu). N'zoonekeratu kuti kuchepetsa nthawi imene kutengerapo deta , liwiro pazipita maukonde ali zochuluka. Apo ayi, ntchito ndi chuma chochuluka maukonde akhoza kukhala chiyembekezo champhamvu cha akamaliza njira kutengerapo.

Liwiro ADSL

luso, amene akadali chimagwiritsidwa ntchito ndi ena owerenga, izi ADSL. Ndi oyimba-mmwamba kugwirizana mtundu chitukuko. Iwo amagwiritsa alipo matelefoni. WOPEREKA PBX kukhala chipangizo wapadera - DSLAM. Wolembetsa Gawo limeneli zikugwirizana ndi kompyuta yoyenera modemu. DSLAM ndi mkhalapakati pakati pa kuwombola ndi zida wolembetsa. Poyerekeza ndi apadera njira chingwe phindu kuti ngati muli ndi landline foni, ndi athandizi yoyenera, ndi Intaneti akhoza kuchitika posachedwapa.

Liwiro pazipita chisankho amenewa zimadalira maonekedwe a mphamvu mzere, dongosolo ndi zipangizo. Choncho, muyezo ADSL ITU G.992.1 alumikiza A (B) «denga" jekeseni liwiro ndi Mbps 12, ndipo amabwerera - 1.3 Mbps (njira zonse asynchronous). Koma ndi bwino njira ADSL2 + (mode ITU G.992.5 alumikiza M) mlingo ziwonjezeke kwa 24 / 3.5 Mbps, motero. owerenga ambiri kunyumba angadalire 8/1 Mbps kwambiri.

yikidwa mawaya analogue

Panopa njira wotchuka kwambiri pa maziko a peyala zopotoka ndi maulalo kuwala. Mbali yoyamba, ndi ochititsa mkuwa deta chingwe ndi opatsirana pa mitengo mpaka 100 Mbps. Gigabit imathamanga kupezeka kwa owerenga wamba mwakamodzikamodzi ngati woyikidwa malire pa kutalika chingwe gawo ku dispenser kwa wolembetsa kompyuta. Zambiri zovuta kuzimvetsa kwambiri mzere analenga pamaziko a mizere kuwala angathe kupatsira pamodzi CHIKWANGWANI osachepera 10 GB deta, ndi kupatsidwa kuthekera potero chiwerengero cha njira mu CHIKWANGWANI wina, chiwerengero mlingo zimafalitsa angathe kuyeza terabits. Pamene kulumikiza kwa CHIKWANGWANI Intaneti chamawonedwe ambiri operekedwa ndi wosuta 100 megabits 1 gigabit.

maulalo opanda zingwe

Chifukwa cha kuchuluka kwa zipangizo kunyamula kulankhulana chidwi ambiri wapadera anali angabweretse funso kodi liwiro pazipita Wi-Fi. Panopa zili kwa Mbps 140 (ngakhale zipangizo 802.11n ananena 300 Mbit / s). amadza yaikulu mphamvu liwiro mizere opanda zingwe kulankhulana ndi zopinga (makoma, etc.) Kodi pakati pa zipangizo.
