Bridges and routers are complex devices with only one easy task. They are the gatekeepers for communication between the local area network (LAN). They determine when to show and convey the data and how to do it.
You should evaluate the role performed by the file server, print server and communication server at various local area network (LAN) if you plan to connect the LAN. Modern computers can run several different roles at the same network, and the people who work on the relationship between the LAN to LAN often require special services from distant LANs.
LAN adapter card translates a low power electrical signals that move data in parallel flow in the serial stream to a computer with greater force in the LAN cable. Because the adapter card is made from the type of transmitter electrical connector and a very special, you take the decision about the type of LAN adapter that you buy will also determine the type of cabling and pen-'s signal that you will use in the network.
The IEEE has created a standard for cabling, signal's pen-and medium access control is IEEE 802.3 standard, commonly referred to as Ethernet. Although the IEEE standard for Ethernet that is original is different, and the standard for token-ring network. 802.3 signaling standard indicates the speed of 10 megabits per second using the media access schemes Carrier Sense Multiple Access (CSMA).
Variation under standard allows for connection with thin coaxial cable, thick coaxial cable, and fiber optic cables. In the 90s, the IEEE approved a standard specification of the series, called the 802.3 10BaseT, which established a standard process to run Ethernet over UTP cable. UTP cables are Unshielded Twisted Pair cable, or better known as the telephone wires.
