What is an Ethernet Switch?
Ethernet switching connects wired devices such as computers, laptops, routers, servers, and printers to a local area network (LAN). Multiple Ethernet switch ports allow for faster connectivity and smoother access across many devices at once.
An Ethernet switch creates networks and uses multiple ports to communicate between devices in the LAN. Ethernet switches differ from routers, which connect networks and use only a single LAN and WAN port. A full wired and wireless corporate infrastructure provides wired connectivity and Wi-Fi for wireless connectivity.
An Ethernet switch works at the data link level. Devices with IPs create packets, which are then housed within an Ethernet frame. Encapsulation. In order to transport the information contained in the IP packet through the network, encapsulation occurs, where bits adhere to the front and back of the packet.
Ethernet switch, the most common form of network switch, is a computer networking device used in Ethernet to connect various Ethernet devices. It connects devices together by using packet switching to receive, process, and forward data from one source device to another destination device.28
in the home or office, the Ethernet switch functions as a central station connecting computers, printers and every other wired device to each other. The switch is also wired to the router and modem to access the Internet. The wireless counterpart to Ethernet is Wi-Fi.
How Does an Ethernet Switch Work?
- Receiving Packets. An Ethernet switch works at the data link level. Devices with IPs create packets, which are then housed within an Ethernet frame.
- Encapsulation. In order to transport the information contained in the IP packet through the network, encapsulation occurs, where bits adhere to the front and back of the packet.
- Processing Identifying Data. The frame contains key identifying data in the header, such as inter alia source, source MAC address and the destination MAC address. When the frame arrives at the Ethernet switch, the switch reads the information and decodes where to forward it through the ports to reach its intended destination.
- Sending Packets. The frame arrives at the destination device, which then receives and strips the packet.
Benefits OF Ethernet Switch
Advantages to using an ethernet switch for your business:
- Reduce network downtime
- Improve network performance
- Increase available bandwidth on your network
- Reduce strain on individual host computers suffer with lower workloads
- Protect your corporate network with more robust security features
- Reduce IT costs with remote management options as well as reduced wiring expenses
- Provide unique network switch connections to specific workstations for further customization
- Streamline future expansion with the use of modular switches
