Ib yam li ntawd, WAN network yog dab tsi? Ib lub computer network uas spans ib cheeb tsam loj heev. Feem ntau, a WAN muaj ob los yog ntau lub zos-chaw tes hauj lwm (LANs). Computers txuas nrog a wide-area network feem ntau txuas nrog pej xeem tes hauj lwm , xws li xov tooj system. Lawv tuaj yeem txuas tau los ntawm cov kab xauj lossis satellites.

Hais txog qhov no, kuv yuav txuas rau WAN network li cas?

Ua raws li cov kauj ruam no, tsis hais tus router qhov teeb tsa kev qhia yuav hais li cas:

Internet yog kev sib txuas lus raws tu qauv rau lub network thoob ntiaj teb ( WAN = Wide Area Network). Ethernet yog kev sib txuas lus raws tu qauv rau Local Area Network (LAN) siv ib yam media interfaces (tsuas yog RJ45 lossis fiber ntau). LAN yog kev sib koom tes sib koom tes tab sis tuaj yeem txuas nrog hauv ib qho WAN dhau Internet cov khoom siv xws li Routers.
