Past mile networks. Telecommunication companies can use fiber-optic connections to provide consumers with Access to the internet and products and services.

A standard house or little Place of work router demonstrating the ADSL telephone line and Ethernet network cable connections A router is really an internetworking device that forwards packets involving networks by processing the addressing or routing information and facts included in the packet.

External network playing cards are of two types: Wi-fi and USB centered. Wireless network card must be inserted in the motherboard, on the other hand no network cable is required to connect to the network.

Inside a LAN, constrained computer and networking equipment are related since its geographical place is small; it's exclusively style for shorter length and useful for sharing sources like information, printers, and World wide web connections amongst related devices; the gadgets are physically linked with cables in wired LAN even though in wi-fi LAN; units are linked employing wireless media.
