Local area network providing data transmission functions

Local area network providing data transmission functions through different types of physical networks. Local area network operates at Layer 1 (physical layer) and 2 (data link layer) in the OSI reference model that works in synergy to carry out data communication with the formation of a good design of your network environment. For more details, reference the OSI model this problem you can read more details in my article the other problems the OSI reference model.

Local area network (LAN) consists of computer, network interface card (NIC), networking media, network traffic control devices, tools and other network peripherals. LAN memungginkan a business office using computer technology for efficient sharing, such as files, printers, and allows communication of information such as e-mail, telephone VoIP, Skype, and others-2.

Local Area Network is designed to do the following:
Operates within the limits of geographical area
Allows all users to access a wide bandwidth media
Providing full-time connectivity to local services
Connecting devices to the extent of adjacent-2 media cable / wireless

Local area network consisting of high-speed network infrastrucktur in one single location that is used to transmit application data and other data services. Local area network technology that is widely used on Ethernet technology budget that is used due to cheapness; easy to use and easy in maintenance and its ability to scale up to gigabit-speed network.

What are the network devices used in network infrastructure local area network? network devices that operate at Layer 2 Data Link is a Bridge, Switch and ATM switches. Switch is a switching device is purely working on layer 2 that allows more efficient use of bandwidth Ethernet. The device switches can localize the impact of the collision (collision) and data contention data (data that were all fighting street - mutually salip two-way streets) in a network. This can be achieved by studying the device address (MAC address) dynamically in the local area network and only to deliver a datagram to the address of the device are eligible to receive it - as if the recipient address in a written letter. What about Bridge? Bridge is the original definition of the functions that can be done by the switch. While the ATM switch is a device that has the ability to function ATM switches. Semenetara local area network devices that operate at Layer 1 is the hub or concentrator or repeater.
