Switches and routers

Finally, what is a Hub? Switches and routers hub has no way of distinguishing which port a frame should be sent to. A hub is a common connection point for devices in a network.

What is a Switch? So conversations regarding these devices can be a bit misleading — especially to someone new to computer networking. Using headers and forwarding tables, routers determine the best path for forwarding the packets.

What is a Router? Switches operate at the data link layer layer 2 and sometimes the network layer layer 3 of the OSI Reference Model and therefore support any packet protocol.

Routers are located at gatewaysthe places where two or more networks connect. This places a lot of traffic on the network and can lead to poor network response times. The Hub and Switch Have Similar Roles Each serves as a central connection for all of your network equipment and handles a data type known as frames.

With this information, a switch can identify which system is sitting on which port. Besides the inherent protection features provided by the NAT, many routers will also have a built-in, configurable, hardware-based firewall. Which device do you use, and when do you use it? When a frame is received, it is amplified and then transmitted on to the port of the destination PC.

So when only one PC is broadcasting, it will have access to the maximum available bandwidth. Hubs connect segments of a LAN. Passing it along to every port ensures that it will reach its intended destination.

Some technicians have a tendency to use the terms routerhub and switch interchangeably. A switch, however, keeps a record of the MAC addresses of all the devices connected to it. So when a frame is received, it knows exactly which port to send it to, without significantly increasing network response times.

If, however, multiple PCs are broadcasting, then that bandwidth will need to be divided among all of those systems, which will degrade performance. Routers use headers and forwarding tables to determine the best path for forwarding the packets, and they use protocols to communicate with each other and configure the best route between any two hosts.

Some of the more high-end or business class routers will also incorporate a serial port that can be connected to an external dial-up modem, which is useful as a backup in the event that the primary broadband connection goes down, as well as a built in LAN printer server and printer port.

So regardless of the number of PCs transmitting, users will always have access to the maximum amount of bandwidth.Shop for your wireless routers, wired routers, ethernet switches, and other networking devices at ultimedescente.com We are here to help.

The Difference Between a Router, Switch and Hub

Routers and switches are both computer networking devices that allow one or more computers to be connected to other computers, networked devices, or to other networks.

The functions of a router, switch and hub and are all different, even if at times they are integrated into a single device.

Routers are located at gateways, the places where two or more networks connect. the connection between the router and switches/hubs may require either straight-thru or crossover (null-modem) cables.

Some routers even have USB ports, and more commonly, wireless access points built into them.
