					                         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.
