LAN ndiyo yotchuka kwambiri yomwe timagwiritsa ntchito masiku ano. LAN ndi chiyani?
A Local Area Network (LAN) amatanthauza gulu la makompyuta olumikizidwa ndi makompyuta angapo mdera lina pogwiritsa ntchito njira yowulutsira. Pamene pali zambiri m'derali, zipangizo zambiri zomwe zimatha kulankhulana. Ndipo ndi LAN yokha ya dongosolo yomwe imatha kulankhulana. Mwachitsanzo, zida kompyuta mu LAN chimodzimodzikusinthaikhoza kulumikizidwa kudzera pa adilesi ya MAC.
LAN ili ndi zinthu zambiri, zomwe zimapangitsa kuti ikhale imodzi mwazodziwika bwino:
Mbali 1: Kulumikizana kwa LAN ndikochepa kwambiri, ndipo kumangolumikizidwa kudera lodziyimira palokha, monga nyumba kapena gulu lomanga lapakati. Zitha kumveka kuti zipinda zomwe zili m'nyumba imodzi zimatha kulumikizidwa wina ndi mnzake kudzera mu elevator.
Mbali 2: Sing'anga yotumizira (yopotoka, chingwe coaxial) choyikidwa mwapadera chimagwiritsidwa ntchito pa intaneti, ndipo chiwerengero chotumizira deta chimakhala chachikulu pamtundu wa 10Mb / s mpaka 10Gb / s. Mwachitsanzo, mu dongosolo lodziyimira pawokha, kaya kupita kuzipinda zosiyanasiyana kapena kufika zipinda zosiyanasiyana ndi elevator imagwiritsidwa ntchito. Zimagwirizana ndi mapangidwe a hardware a mawonekedwe a netiweki omwe amagwiritsidwa ntchito.
3: Kuchedwa kwa kulumikizana kwakanthawi, kulakwitsa pang'ono, komanso kudalirika kwakukulu.
4: Masiteshoni onse ndi ofanana ndikugawana njira yotumizira.
Gawo 5: Imagwiritsa ntchito kuwongolera kogawidwa ndi kulumikizana kwapawayilesi, ndipo itha kugwiritsidwa ntchito powulutsa komanso kuwulutsa kwamitundu yambiri.
Zinthu zazikulu zomwe zimapanga LAN ndi topology yake ya network, media media, ndi njira zake zowongolera kupezeka kwa media.
Zomwe zili pamwambazi ndi kufotokozera kwa chidziwitso choyambirira cha LAN chobweretsedwa ndi Shenzhen HDV Phoelectron Technology Co., Ltd., wopanga zida zoyankhulirana zowunikira.
