TCP/IP is the most common LAN protocol.
LANs can be of wireless or wired type.In wireless LAN access points can be used tointerconnect the LANs and to Connect wired LANs bridges can be used. By naghma
Ethernet is the most popular network technology used on wired LANs. And IEEE 802 i.e Wi-fi is used for wireless LANs. -- By MyNarutoAnime ----
TCP/IP is the protocol used to communicate on most networks.
The older protocol for this purpose was BOOTP, but modern addressing LAN schemes today will use DHCP.
yes, most LANs used by businesses today are client/server networks
The first protocol that was used by the APARNET was called the Internet Protocol.
Yes, STP is used in LANs where EM interference is present.
Today, Ethernet LAN has one competing LAN technology: WLANs.
It uses a serial protocol for transferring data. This protocol is different to the protocol of the classical old serial connection that is not used any more in modern computer hardware.
Network cards are used to connect a personal computer to a LAN. A computer with a network card can be a network participant.Hubs are used to connect participants (PCs and other LAN devices).Bridges are used to connect parts of LAN with each other. Possibly because they operate on a different medium (copper wire, glass fibre).Routers are used to connect networks with each other (LANs with other LANs; LANs with the internet, etc.)Switches are a mix between Hub and Bridge.
Radio Frequency
the protocol used for email is simple mail transfer protocol and the layer is transport layer.
