In Ethernet (a group of computer networking technologies commonly used in local area networks (LANs), metropolitan area networks (MANs), and wide area networks (WANs). There are a number of network devices that play their own roles at various levels. It can be a concentrator, a switch and a router. The functions of these three devices are completely different, even if they are integrated into the same device. Therefore, many people will feel confused about the difference between Hub, Switch and router. This article will share with you what Switch is? What is the function of the Switch? What is the difference between Hub, Switch and Router?


Definition of Switch

?Switch is a switching device that acts as a central device, it is used to connect network segments together in a star model. All computers are connected to the Switch in a network. Switch facilitates resource sharing by connecting all devices; including computers, printers and servers; in a small business network. Thanks to the Switch, these connected devices can share information and talk to each other; no matter where they are installed in the building. If you build a small business network; then a switch such as a switch is indispensable. Switch switches are used in wired networks to connect to other devices with an Ethernet cable. Switches allow each connected device to talk to other devices. Wireless networks do not use Switches; because devices like wireless routers and adapters will communicate directly with each other.

?Although the ports on the back of a router or modem can be used to connect Ethe devices together. But the Switch switches will provide some of the following advantages:

Switch allows you to connect a lot of devices. Keeps traffic between two devices unimpeded by other devices on the same network. Allows you to control who can access different parts of the network. of the network.Allows you to monitor the usage of connected devices.You can communicate with other devices on your network faster than the Internet.Advanced Switches are adjustable. according to your network needs.

Hubs, Switches and Routers are the most commonly used network devices today. They are used to connect nodes such as PCs, printers, scanners, projectors, etc. in the network.

What’s the difference between Hub, Switch and Router

?What is a Hub?

Hub is a device used to connect segments of a LAN. A hub will have many ports, when a packet arrives at one port, it is copied to other ports for the purpose of helping other ports to recognize the packet. Hub acts as a central point for devices in the network.

2. What is a Switch?

Switch is a network device that operates according to the data link layer of the OSI model (star model). In LAN, switches are used to join segments called switched LANs. In networks, a switch is a device that filters and forwards packets between LAN segments.

3. Router (Router)?

Router, or router, is a device that forwards data packets along a network. Routers connect two networks together; usually a LAN and a WAN or a LAN with an Internet service provider. It has the function of sending network data packets between 2 or more networks; from one to many final destinations from the Router. Therefore, in the Internet, the router is in a position where there are two or more networks connected to each other.

For Switch and Hub, each device acts as a central connection for all network devices. It processes a form of data called a “frame” and each frame carries data. However, the two devices differ in the way they communicate. A 10/100Mbps hub must share the bandwidth with all its ports; without having to distinguish between ports. A 10/100Mbps switch will deliver the full 10/100Mbps rate to each device port. Because a network switch keeps a memo of the MAC addresses of all the devices it connects to. So, when the data frame is received, the Switch knows exactly which port to send to; maximizes network response time. So, with the Switch, it doesn’t matter how many PCs transmit data; users always get maximum bandwidth.

— Routers are completely different from Hub and Switch devices. While Hub and Switch are concerned with data frame transmission; The router’s function is to route packets on the network until they reach their final destination. It contains not only the data, but also the destination address, indicating where it is going. The router can decide which path is best to use to transmit the packet. Routers use ICMP protocol to communicate with other routers; help configure the best transmission between any two hosts.
