![]() ![]() One of the key aspects or features of a packet is that it not only contains data, but it also contains the destination address of where it is going.Ī router is typically connected to at least two networks, which are commonly two Local Area Networks (LANs) or Wide Area Networks (WAN) or a LAN and its ISP’s network – for supposing, your PC and your service provider. Where a hub or switch is concerned with transmitting the frames, a router’s job, as for its name implies, is to route the packets to other networks until that packet ultimately reaches its destination. Routers are completely different from these devices. Routers are completely different devices. It is for these reasons that a switch is considered to be a much better choice than a hub. So despite the number of PCs transmitting, users will always have access to the maximum amount of bandwidth. So that when a frame is received, it will know exactly which of the port to send it to, without considerably increasing network response times.Īnd unlike a hub, a 10/100 Mbps switch will allocate a full 10/100 Mbps to each of its ports. With this information, a switch can recognize and identify which system is sitting on which port. Whereas, a switch keeps a record of the MAC addresses of all of the devices which are connected to it. ![]() If, though, multiple PCs are broadcasting, then that bandwidth will then need to be divided among all of those systems, which will then degrade the performance. So when only one PC is broadcasting, it will have access to almost the maximum available bandwidth. In addition to that, a 10/100 Mbps hub must share its bandwidth with every one of its ports. The places a lot of traffic on the network and it can lead to poor network response at some of the times. Passing it down to every port makes sure that it will reach its intended destination. The hub has no way of differentiating that which port a frame should be sent to. It does not matter that the frame is only meant for one port. In a hub, a frame is passed along or “broadcast” to every one of its ports. The biggest difference between these two devices is that the method in which the frames are being delivered is different in both of these devices. When a frame is received, it is then amplified and transmitted on to the port of the destination PC. The Hub and Switch Have Similar RolesĮach of these devices serves as a central connection for all of your network equipment and it handles a data type which is known as frames.įrames are the ones that carry your data. Let us start with the hub and the switch as these are the two devices that have a similar role on the network. The features of a router, hub, and switch are all a bit different from one another, which at some times, are considered to be integrated into a single device. So, the conversations which are regarding these devices can be a bit of a misleading – particularly to someone new to computer networking. Today, most of the routers have become something of a Swiss Army knife, which combines the features and functionality of a router, and witch-hub into a single unit. The differences between these devices on the Network It includes multiple ports so that when a packet arrives at one port, it is then copied to the other ports so that all of the segments of the LAN can see all the packets. ![]() What is the Hub?Ī hub is a common connection point for the devices in a network. LANs which use switches to join the segments are called switched LANs or, as for the Ethernet networks, it is called switched Ethernet LANs. Switches function at the data link layer (layer 2) and at some of the times operate the network layer (layer 3) of the OSI Reference Model and therefore it supports any of the packet protocol. In networks, the switch is a device that filters and forwards the packets between LAN segments. Routers use headers and forwarding tables to determine the best path for forwarding the packets, and they also use the protocols to communicate with each other and configure the best route between any of the two hosts. Routers are located at gateways which are the places where two or more networks are connected. It is connected to at least two networks, which are commonly two LANs or WANs or a LAN and its ISP’s network. The router is a device that forwards the data packets along with the networks. Now, let’s discuss which device should you use, and when do you use it? What is a Router? The functions of all the three devices – the router, switch and a hub – are all quite different from one another, even if at some of the times they are all integrated into a single device.
