Question

What is the difference between Bridge and Switch..?

Answer 1

Switch is used to connect many systems to form a network

Bridge is used to connect two different networks

Answer 2

A network bridge connects multiple network segments at the data link layer (layer 2) of the OSI model, and the term layer 2 switch is often used interchangeably with bridge. Bridges are similar to repeaters or network hubs, devices that connect network segments at the physical layer, however a bridge works by using bridging where traffic from one network is managed rather than simply rebroadcast to adjacent network segments. In Ethernet networks, the term "bridge" formally means a device that behaves according to the IEEE 802.1D standard—this is most often referred to as a network switch in marketing literature.

Answer 3

A switch works on a single subnet, to connect computers on a private LAN with addresses of 192.168.1.x

A bridge joins two subnets or other networks, such as 192.168.1.x and 192.168.2.x

Answer 4

Bridge

A computer bridge is a device that connects two local-area networks (LANs), or two segments of the same LAN. Unlike a router, bridges are protocol -independent. They simply forward packets without analyzing and re-routing messages.

Router

A hardware device designed to take incoming packets, analyzing the packets and then directing them to the appropriate locations, moving the packets to another network, converting the packets to be moved across a different type of network interface, dropping the packets, or performing any other number of other types of actions. To the right is a picture of the Linksys BEFSR11 router and is similar to what most home users would use for their home network.  

A router has a lot more capabilities than other network devices such as a hub or a switch that are only able to perform basic network functions. For example, a hub is often used to transfer data between computers or network devices, but does not analyze or do anything with the data it is transferring. Routers however can analyze the data being sent over a network, change how it is packaged and send it to another network or over a different type of network. For example, routers are commonly used in home networks to share a single Internet connection with multiple computers.
