large installed base (500 million Ethernet nodes) more than 95% of LAN traffic is Ethernet based. Ethernet supports 10 Mb/s, 100 Mb/s (Fast Ethernet), 1 Gb/s (Gigabit Ethernet) and 10 Gb/s (10GbE) Ethernet standardized by IEEE (802.3 standard series) Widespread popularity. Specifications and rights to build and install Ethernet made easily ...
A local area network generally provides high-bandwidth communica- tion over inexpensive transmission media. This paper discusses what local area networks are, their structures, the sorts of protocols that are used with them, and their applications. It also discusses the relationship of local area networks to long-

The first is the easy access to information this type of computer network provides. In a LAN network, a user can easily access data from any computer or any device within the network. For example, in a school-based LAN network, if a user needs urgent access to data stored in any of the school computers linked to the LAN, he or she could easily acce...
Client-Server LAN The Client-Server LAN is a network of multiple clients' devices, and they all are connected with the central server. All the devices in the network are connected with one server either through cables or a wireless connection. The server performs the heavy tasks for all the connected devices like network traffic management, files a...
In LAN, there can be desktop computers, laptops, printers, wifi-modem, servers to respond to requests, routers, and switches for connecting two or more LANs, etc. The cables like Ethernet are used to connect all the devices in a LAN. The LAN is used for short areas like the home, offices, schools, etc., but the network's size varies depending on th...
MAN (metropolitan area network)is a network of computers and resources set up in a large geographical area that can range from 50 km to around 60 km. MANs are usually several LANs connected together. They are used in a group of buildings, a town or even a city. MANs are larger than LANS but smaller than WANs.
WAN stands for wide area network. A WAN is a telecommunication network used mostly by organizations to interconnect their offices located in different parts of the world and allow their staff to have access to one centralized data hub. While a MAN network can cover cities and towns, a WAN network has a much larger scope. A WAN network can cover cou...
Example 1: Wireless Local Area Network. In this LAN example, a typical local area network is shown consisting of a server, router, access points, and mobile clients. However, unlike traditional LANs, mobile clients are not connected to the access points via physical wires or cables. Rather, each of the mobile clients is connected to its ...
A local area network(LAN) is a network of computers, located physically close to one another. (The Internet, by the way, is a WAN, or wide area network, that connects millions of LANs.) A LAN consists of two or more computers, each equipped with a communications device called a network interface or network adapter. The network interfaces are ...
Identify the cable that connects your computer to the network. Disconnect the cable (finish any downloads from the Internet if in progress first) and view the connector. If you are connected via a cable, attempt to identify what device is connected to the other end of the cable, such as a hub, switch, or router.
The Local Area Network A local area network (LAN) can be defi ned as a group of devices connected in a spe-cifi c arrangement called a topology. The topology used depends on where the network is installed. Some common legacy topologies such as the bus and ring and more modern topologies such as the star and mesh are discussed later in this chapter.
