International Standard wasonyeza kuti unit deta ntchito ndi manambala oyambirira SI. Monga wagawo aliyense wa muyeso, pali specifications bwinobwino Akamva ndi mabayiti. Choncho, megabit ndi wofanana ndi zisanu wani handiredi ndi twente mabayiti 8-bit, ndi mazana makumi awiri ndi asanu kilobytes ndi za zana ndi makumi awiri awiri kibibyte. Mu kutumiza mauthenga kapena Intaneti kompyuta ntchito dzina lakuti "Megabits" amene amadziwika mlingo pa zimene deta imafalikira mu maukonde.

Koma chiphunzitso tsopano kwa kulingalira mizere alipo zosiyana mu njira ya HIV zambiri. Kuonetsetsa wireline, chingwe ndi opanda zingwe. Choyamba ntchito kufala kwa deta kompyuta ndi chizindikiro telefoni. Pa iwo zikugwira njira kufala kwa mudziwe onse analogi ndi yadigito. Ndi mizere kulankhulana chingwe, amene amagwira ntchito Intaneti computer, chingwe monga mitundu itatu: zopotoka awiri (deta mlingo pa ndi ku megabits 10 100 pa mphindi), coaxial (ntchito Intaneti Efaneti) ndi CHIKWANGWANI chamawonedwe chingwe. Yotsirizira amatha kupereka chizindikiro mu njira imodzi yokha. Koma kwambiri kutetezedwa chopinga ndiponso amatha kusintha liwilo deta - mpaka gigabits atatu pa mphindi.

Chifukwa limasonyeza opanda zingwe monga ma ndi Kanema aya. Komanso, akatswiri kuzindikira kuti tsogolo limabweretsa njira imeneyi kulankhulana, amene safuna mawaya.

Intaneti 3G anayala mu Russia chifukwa cha kutsogolera ntchito mafoni Beeline, MTS ndi Megafon. Pofuna kupindula ndi mwayi maukonde, zokwanira ndi foni kapena USB-modemu, amene amathandiza Intaneti lachitatu m'badwo. The foni basi wayamba ntchito zopezera 3G ngati sikukukolana ndi GSM chizindikiro. Izo sikutanthauza kasinthidwe zina. Kwa mlingo deta chipangizo ayenera kugwiritsa «3G Only» mode, zomwe zimathandiza kuti atembenuke 3G-osachiritsika (modemu kapena foni yam'manja) mu mode UMTS. Motero, ngakhale pa mbendera ofooka angadwale liwiro Download deta Internet.

chizindikiro amenewa wailesi popereka deta monga Wi-Fi, WiMAX angathe akupereka mauthenga pa mtunda wa makilomita mpaka makumi asanu ndi kupereka pa yomweyo liwiro mpaka sevente-megabits pa mphindi.

Mugulu la UMTS, liwiro pazipita la kufalitsa deta ndi wofanana kilobytes forte-eyiti pa mphindi. Izi zokwanira kuona ukonde-masamba. Koma chifukwa zinthu zatsopano, pali HSPA luso, imene inkatchedwa 3,5G. Izi mkulu-liwiro paketi deta kufala kuchokera maukonde kuti kasitomala (HSDPA) ndi kwa kasitomala kwa maukonde (HSUPA). Chifukwa cha luso latsopano, nkhani anasamutsa pa liwiro la 3.6 Mbit / gawo. Osati zipangizo zamakono onse angathe ntchito ndi izo.

Intaneti imayendetsedwa ndi thandizo la zingwe. mawonekedwe kugwirizana kwa maukonde ndi ofala pakati eni ma PC n'kupuma. Pamene ntchito chingwe coaxial, mlingo deta ikhoza kukhala pakati mazana awiri mphambu makumi asanu ndi faifi handiredi kilobits pa mphindi. Ngati zingwe ziwiri ntchito, ndiye munthu amalandira baseband chizindikiro, ndipo chachiwiri - ndi powerengetsera chizindikiro. Data imafalikira pa HDLC mtundu chikukhudza kupatula zokhudza chiyambi ndi mapeto a uthenga, komanso zambiri kulamulira.
