    A router IS a switch with additional features. The router provides DHCP services and other functions. You would use a Router to create a network that shares the internet with all of the computers in your local area network. A switch would only be used to extend that network to more computers and other devices.

    A router is a device which connects networks. A switch is a device that intelligently connects computers within a network.

    Most routers today connect your local network to the biggest network in the world, the Internet.

    Most routers today come with a switch built in and are really a combination router/switch.

    A switch is kind of like a splitter. If you have 10 computers that need to connect to one source, you use a switch.

    A router usually has a switch built in (on the residential versions). A router is needed in able to split a signal from the outside.

    Whereas a switch takes information from one computer and passes it along to another computer near it, a router creates a segment. It creates a group of computers on the same network able to communicate with eachother, but when communication with something outside of the router's network is needed, the router asks for the communication on behalf of the computer below it.

    Answer: A router is a more sophisticated network device than either a switch or a hub. Like hubs and switches, network routers are typically small, box-like pieces of equipment that multiple computers can connect to. Each features a number of "ports" the front or back that provide the connection points for these computers, a connection for electric power, and a number of LED lights to display device status. While routers, hubs and switches all share similiar physical appearance, routers differ substantially in their inner workings.

    Traditional routers are designed to join multiple area networks (LANs and WANs). On the Internet or on a large corporate network, for example, routers serve as intermediate destinations for network traffic. These routers receive TCP/IP packets, look inside each packet to identify the source and target IP addresses, then forward these packets as needed to ensure the data reaches its final destination.

    Routers for home networks (often called broadband routers) also can join multiple networks. These routers are designed specifically to join the home (LAN) to the Internet (WAN) for the purpose of Internet connection sharing. In contrast, neither hubs nor switches are capable of joining multiple networks or sharing an Internet connection. A home network with only hubs and switches must designate one computer as the gateway to the Internet, and that device must possess two network adapters for sharing, one for the home LAN and one for the Internet WAN. With a router, all home computers connect to the router equally, and it performs the equivalent gateway functions.

    Additionally, broadband routers contain several features beyond those of traditional routers. Broadband routers provide DHCP server and proxy support, for example. Most of these routers also offer integrated firewalls. Finally, wired Ethernet broadband routers typically incorporate a built-in Ethernet switch. These routers allow several hubs or switches to be connected to them, as a means to expand the local network to accomodate more Ethernet devices.

    In home networking, hubs and switches technically exist only for wired networks. Wi-Fi wireless routers incorporate a built-in access point that is roughly equivalent to a wired switch.

    special purpose computer is called router to connect lan and wan.


    switch is used for connecting with in the network.

    importance of switch is to create the vlan
