Switches and routers

Hubs connect segments of a LAN. Standard Features of Integrated Routers Today, a wide variety of services are integrated into most broadband routers.

The router forwards data packets along networks. A hub is a common connection point for devices in a network. This places a lot of traffic on the network and can lead Switches and routers poor network response times.

So when a frame is received, it knows exactly which port to send it to, without significantly increasing network response times. What is a Switch? If, however, multiple PCs are broadcasting, then that bandwidth will need to be divided among all of those systems, which will degrade performance.

So conversations regarding these devices can be Switches and routers bit misleading — especially to someone new to computer networking. 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.

Some technicians have a tendency to use the terms routerhub and switch interchangeably. So when only one PC is broadcasting, it will have access to the maximum available bandwidth.

The Devices Defined The functions of the three devices — the router, switch and hub — are all quite different from one another, even if at times they are all integrated into a single device.

Using headers and forwarding tables, routers determine the best path for forwarding the packets. With this information, a switch can identify which system is sitting on which port. Frames carry your data.

Passing it along to every port ensures that it will reach its intended destination. 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. A switch, however, keeps a record of the MAC addresses of all the devices connected to it.

The big difference between these two devices is in the method in which frames are being delivered. What is a Router?

When a frame is received, it is amplified and then transmitted on to the port of the destination PC. Firewall capabilities can range from the very basic to quite sophisticated devices. Routers are Completely Different Devices Routers are completely different devices.

Besides the inherent protection features provided by the NAT, many routers will also have a built-in, configurable, hardware-based firewall.

Switches & Routers

Some routers even have USB ports, and more commonly, wireless access points built into them. In networks the switch is the device that filters and forwards packets between LAN segments. Which device do you use, and when do you use it? It contains multiple ports so when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.

Finally, what is a Hub? 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.

Router use protocols such as ICMP to communicate with each other and configure the best route between any two hosts. In a hub, a frame is passed along or "broadcast" to every one of its ports.

The functions of a router, hub and a switch are all quite different from one another, even if at times they are all integrated into a single device. So regardless of the number of PCs transmitting, users will always have access to the maximum amount of bandwidth. The hub has no way of distinguishing which port a frame should be sent to.

Router vs Switch vs Hub: Routers are located at gatewaysthe places where two or more networks connect.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, switches, and hubs are three types of devices found on Ethernet networks.

The Difference Between a Router, Switch and Hub

Although they may look similar, each of them works differently. Switches and routers are the building blocks for all business communications, from data to voice and video to wireless access. They can improve profitability by helping your company increase productivity, trim business expenses, and improve security and customer service.
