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.
A router or a Layer-3 switch can connect 2 or more LANs together and control data flow between them.
The type of network that connects multiple LANs is called a WAN (wide area network). A typical example of a WAN is the network that links the different departments of an organization.
A router that supports two or more communications protocols, such as IP and IPX. It is used to switch network traffic between different LANs located throughout the enterprise as well as to switch LAN traffic to WANs.
You can join LANs and WANs with a Hub, Router, Switch, Gateway, Bridge, Network Interface Card (NIC) and a WAP (Wireless Access Point)..
WAN ( Wide Area Network )
LAN (Local Area Network) is different to a WAN (Wide Area Network) in that a WAN is a network that joins two different LANs. e.g. You may have two office, one in London and one in Manchester. They will have their own LANs. If they link their networks together it will become a WAN.
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
LAN means Local Area Network. It can connect computers within buildings and a limited area and can also share resources like printers.
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 ----

Yes, it can.
