Local Area Network (LAN)
Amatanthauza gulu la makompyuta lopangidwa ndi makompyuta angapo olumikizidwa kudera linalake.Nthawi zambiri, imakhala mkati mwa mita masauzande angapo m'mimba mwake.LAN imatha kuzindikira kasamalidwe ka mafayilo, kugawana mapulogalamu a pulogalamu, kusindikiza
Zina zimaphatikizanso kugawana makina, kukonza m'magulu ogwira ntchito, maimelo ndi mauthenga a fakisi, ndi zina zambiri.Ma network amderali atsekedwa ndipo amatha kukhala ndi makompyuta awiri muofesi.
Itha kukhala ndi makompyuta ambiri mkati mwa kampani.
Wide Area Network (WAN)
Ndi gulu la maukonde apakompyuta omwe amatenga gawo lalikulu, lachigawo.Nthawi zambiri kudutsa zigawo, mizinda, ngakhale dziko.Ma network ambiri amaphatikiza ma subnet amitundu yosiyanasiyana.Ma subnet akhoza
Itha kukhala maukonde amdera lanu kapena netiweki yaying'ono.
Kusiyana pakati pa netiweki yakumaloko ndi netiweki yadera lalikulu
Malo ochezera a m'derali ali m'dera linalake, pamene maukonde amtundu waukulu amatenga malo akuluakulu.Ndiye mungafotokoze bwanji derali?Mwachitsanzo, ofesi yaikulu ya kampani yaikulu ili ku Beijing.
Beijing, ndipo nthambi zafalikira m'dziko lonselo.Ngati kampaniyo ilumikiza nthambi zonse palimodzi kudzera pa intaneti, ndiye kuti nthambi ndi netiweki yaderalo, ndi likulu lonse.
Network network ndi network yadera lonse.
Kodi pali kusiyana kotani pakati pa doko la WAN ndi doko la LAN la rauta?
Ma rauta amakono a Broadband ndi njira yophatikizika ya routing + switch.Tikhoza kuganiza za izo ngati zipangizo ziwiri.
WAN: Amagwiritsidwa ntchito polumikizana ndi ma adilesi akunja a IP, nthawi zambiri amatanthauza kutuluka, ndi kupititsa patsogolo mapaketi a data a IP kuchokera ku mawonekedwe amkati a LAN.
LAN: Amagwiritsidwa ntchito polumikizana ndi adilesi yamkati ya IP.Mkati mwa LAN pali chosinthira.Sitingathe kulumikiza ku doko la WAN ndikugwiritsa ntchitorautamonga wambakusintha.
LAN yopanda zingwe (WLAN)
WLAN imagwiritsa ntchito mafunde a electromagnetic kutumiza ndi kulandira deta pamlengalenga popanda kufunikira kwa ma waya.Kutumiza kwa data kwa WLAN tsopano kumatha kufika 11Mbps, ndipo mtunda wotumizira ndi
Ndi mtunda wopitilira 20km.Monga njira ina kapena kukulitsa maukonde achikhalidwe, ma LAN opanda zingwe amamasula anthu pamadesiki awo ndikuwalola kugwira ntchito nthawi iliyonse.
Kupeza zidziwitso kulikonse kumawongolera magwiridwe antchito aofesi.
WLAN imalumikizana pogwiritsa ntchito wailesi ya ISM (Industrial, Scientific, Medical).Muyezo wa 802.11a wa WLAN umagwiritsa ntchito 5 GHz frequency band ndipo umathandizira kwambiri
Liwiro lalikulu kwambiri ndi 54 Mbps, pomwe miyezo ya 802.11b ndi 802.11g imagwiritsa ntchito gulu la 2.4 GHz ndi liwiro lothandizira mpaka 11 Mbps ndi 54 Mbps motsatana.
Ndiye WIFI yomwe timakonda kugwiritsa ntchito intaneti ndi iti?
WIFI ndi ndondomeko yogwiritsira ntchito maukonde opanda zingwe (kwenikweni ndondomeko yogwirana chanza), ndipo WIFI ndi muyezo wa WLAN.WIFI network imagwira ntchito mu 2.4G kapena 5G frequency band.Zina
3G / 4G yakunja imakhalanso ndi intaneti yopanda zingwe, koma ma protocol ndi osiyana ndipo mtengo wake ndi wokwera kwambiri!
Virtual Local Area Network (VLAN)
Virtual LAN (VLAN) imatanthawuza ukadaulo wapa netiweki womwe umalola masamba omwe ali pa netiweki kugawidwa mosavuta m'magulu osiyanasiyana malinga ndi zosowa zawo, mosasamala kanthu komwe ali.
Mwachitsanzo, ogwiritsa ntchito pazipinda zosiyanasiyana kapena m'madipatimenti osiyanasiyana amatha kujowina ma LAN osiyanasiyana ngati pakufunika: chipinda choyamba chimagawidwa mu gawo la 10.221.1.0 network, ndipo chipinda chachiwiri chimagawidwa kukhala
10.221.2.0 network gawo, etc.
