The Ethernet switch is used for transmitting data to local area networks. Since its introduction in 1980, it has become the standard way to connect home and small office networks around the world. Get insights on Ethernet switches and how they function.
Facts about the Ethernet Switch The Ethernet switch is the network switch used for transmitting data at typical Ethernet rates. The network switch can also be used to refer to a device that holds together various parts of the computing network. Development The Ethernet standard was created in 1980. The Ethernet is set upon the IEEE 902.3 standard. Its development would lead to the demise of the Arcnet and the token ring as the primary model of LANs (local area networks). The switch has to be ready to relay data at a precise level. This is necessary to ensure all connected devices and computers are functioning properly. Requirements To be a part of the Ethernet network, the hubs and switches must have the capacity to hold 10/100 Megabits every second / 10/100/1000 Mbit/s ports. There are also larger Ethernet switches. Some can reach up to 10 Gigabits per second (Gbit/s) ports. The hubs and the switches have to conform to the basic standards. However, it is possible for switches to have several ports running at varying speeds. Switches and LANs The switch performs the role of the LAN traffic control center. This is true whether the LAN connection concerns computers, printers or other devices. it is the task of the network switch to handle the data packet transmission that occurs among the various devices. The most frequent utilization of the 10/100 MBits/s switch is to oversee data flow on a home network or office. The typical configuration has an Internet router, a printer and four computers. The switch ensures that all the data can be sent without any problems. In a local area network setup, the switch works to make microsegmentation. Every computer will have its own connection and Internet bandwidth. These are used for connecting to the other network devices. The setup allows for every device to work to the maximum capacity without compromising other components. How the Switch Works The switch handles all these connections via a table that lists all the ports and destination addresses. After receiving a data packet, it will check the header information for the address. The switch will make a temporary link between the addresses. The data packet is then relayed to the proper location. The link is then closed. To understand how this works, recall the telephone operators. The operator would catch all the calls. They will determine who it is you want to call. The operator would insert a plug in a slot to make a temporary link to make communication possible. Once the conversation is finished, the connection would be closed. This would be available for the subsequent caller. That is pretty much the way an Ethernet switch works. As the operator, its goal is to allocate the resources properly for all the devices. References: http://www.tech-faq.com/ethernet-switch.html http://www.tech-faq.com/ethernet.html
