People tend to benefit from a switch over a hub if their home network has four or more computers, or if they want to use their home network for applications that generate significant amounts of network traffic, like multiplayer games or. The prior difference is that logically the hub works like a bus where the same signal is transmitted to all the connections. Hubs are incapable of processing either layer2 or layer3 information, and thus cannot make decisions based on hardware or logical addressing. However the biggest difference is not on the outside, but on the inside in the way that they handle connections. Now, after a fresh start, if devicea sends out a message to deviceb then just like a hub, switch will send it out to each port. Like hubs and switches, routers are typically small, boxlike pieces of equipment that multiple computers can connect to. A hub is a small, simple, inexpensive device that joins multiple computers together. The switch statements selects the execution of the statement often based on a.

Conversely a switch uses layer 2 routing to determine the correct logical path by keeping a record of what hosts have communicated in the past arp tables. Initially, a switch knows nothing, and simply sends on incoming messages to all ports. A network switch moves data between two network devices, while a router generally routes data between two connected networks the router is a device that some think of as a dispatcher which sits between two networks and directs data traffic, connecting one network to another.
