Introduction to Ethernet LANs and WANs

Ethernet LAN

Ethernet is a computer technology that typical LAN connected. LAN means Local Area Network and refers to any computer network that includes more than one computer.

Examples of LAN

An office where all computers are connected to a LAN. The computers can share the hard drive to give all users access the same files to be achieved. They can also be connected to the same scanner and printersThe importance of individual children is not necessary for the individual. In the case of LANs for office can be very effective cost affective. Schools, colleges and universities often use the LAN for many of the same reasons. This means that each site can be used by anyone with access rights, which means that one computer per student is not required, since not all use them simultaneously. Other institutions such as the airport also make use of local networks. Inthis case means that the same information can be accessed from any computer, for example. all desktops

Introduction to Ethernet

LANs are usually connected via Ethernet cables. Ethernet is a system of cables used to connect networks. It 'was convened by Bob Metcalfe, and since 1973 in one form or another. It is by far the most widely used LAN standard for the connection. There are other alternatives, but Ethernet is clearly the leader inin terms of popularity.

Ethernet card

We are now in an era of wireless network, which means that in many cases, a large number of cables is not necessary. LAN and Internet connections can often be achieved using wireless systems today. This means that you can access the network at any location within a given area, depending on the size of the wireless network. This means that users can be more mobile and should not be at their meetingdesk in the same place all the time with a cable connected to the case of Internet access, allowing users to move around the office or a house (or garden), while it is still possible to win. For wireless networking, Ethernet cards are often used. This key does the same work of an Ethernet cable, but without the need or the limitation of wires.

WAN

WAN stands for Wide Area Network, which runs on a network, an area much largeras LAN, sometimes associated systems throughout the world. The Internet is an example of WAN. Ethernet standard now used for WAN LAN the same way. Air systems used worldwide in the airport is about a good example of a WAN.

Fast Ethernet

Fast Ethernet is simply a faster version of a normal Ethernet. Whereas regular Ethernet traffic contributes a speed of 10 Mbit / s Fast Ethernet traffic contributes ten timesfaster than 100 Mbit / s.
