An Ethernet switch connects parts of a computer network and transmits data at standard Ethernet speeds. It must meet specific speed requirements and manages connections through a table of destination addresses and ports. It creates micro-segmentation in a LAN setup and improves network effectiveness.
An Ethernet switch is a network switch that transmits data at standard Ethernet speeds. An Ethernet is a collection of computer networking tools brought together with a specific set of standards. A network switch is another term for a device that connects different parts of a computer network together.
Developed in the 1980s, Ethernet networks are based on the IEEE 802.3 standard. The Ethernet model has replaced the Token Ring and Arcnet models of local area networks. An Ethernet switch must be able to transmit data at a specific level in order for connected computers and devices to function properly.
To be considered an Ethernet network, switches and hubs must carry 10/100 Megabits per second (Mbit/s) or 10/100/1000 Mbit/s ports. Ethernet switches are also available in larger sizes, up to 10 Gigabit ports per second (Gbit/s). It’s important to remember that while both switches and hubs must be able to meet the basic standard, switches can have multiple ports that operate at different speeds.
An Ethernet switch is the traffic control center for the local area network (LAN). A LAN is a method of connecting multiple computers, printers, Internet routers, and other related devices. Network switches are required to handle the transmission of data packets between multiple devices.
The most common use of the basic 10/100 MBit/s switch is to manage a small business or home network. A standard setup would include four computers, a printer and an internet router. The switch ensures that information can be sent between the connected.
In a LAN setup, the Ethernet switch works to create micro-segmentation. Each computer has dedicated internet bandwidth and connection to other devices on the network. This structure allows all devices to operate at their maximum capabilities without impacting other connected devices.
The Ethernet switch manages these connections through the use of a table that lists all the destination addresses and connected ports. When a data packet is received by the switch, it reads the address from the header information and then creates a temporary connection between the two addresses. The data packet is then routed to the destination and the connection is closed.
To understand how an Ethernet switch works, think back to the original carriers. The operator would intercept all incoming calls and determine who the caller wanted to be connected with. They would then insert a cable into the recipients slot and create a temporary connection to facilitate communication.
Once the call ended, the telephone operator released the connection, making that line available to the next caller. The Ethernet switch acts as an operator, managing available resources for maximum efficiency while ensuring that the proper connections are made. Switch efficiency improves network effectiveness.
