\i have to submit an assignment on LAN tomorrow..
what iis LAN...what are the devices and components of a LAN...
what is "topologies" in LAN?...what are the uses and benefits of LAN......pleeeeeeeeeeease help....can you send me links where i can find stuff ...and or can you give me a summary???..it is urgent...have to finish it in an hour or two....thanks...

LAN is local area network.
The Devices of LAN are

* PCs/workstations and servers
* Network Interface Card (NIC)
* Cabling and connectors, for example, coaxial cable and BNC connector, Unshielded Twisted Pair (UTP) and RJ-45 connector
* Hub, concentrator, and more complicated network devices such as Bridge, LAN Switch and Router

The Components of Lan are
The software components of a LAN can be grouped into two categories:

1. Inside PCs/workstations and servers

* NIC Drivers
* Network Operating System for servers, for example, Novell® Netware 4.1 or Microsoft Windows® NT
* Network Operating System for clients (PCs/workstations), for example, Novell® Netware 4.1 client or Microsoft Windows® 95
* Networking protocol software, for example, TCP/IP, Novell® IPX
* Application software, for example, emails, Internet Web Browser

2. Inside network devices (Hub/Bridge/LAN Switch/Router)

* Network Management Software, for example, Simple Network Management Protocol (SNMP), Remote Network Monitoring (RMC)
* Forwarding/routing & control software, for examples, transparent bridging, spanning tree and IP routing software.


Topology refers to the shape of a network, or the network's layout. How different nodes in a network are connected to each other and how they communicate are determined by the network's topology.

LAN allows you to surf faster and share stuff.

LAN - local area network

A computer network that spans a relatively small area. Most LANs are confined to a single building or group of buildings. However, one LAN can be connected to other LANs over any distance via telephone lines and radio waves. A system of LANs connected in this way is called a wide-area network (WAN).
Most LANs connect workstations and personal computers. Each node (individual computer ) in a LAN has its own CPU with which it executes programs, but it also is able to access data and devices anywhere on the LAN. This means that many users can share expensive devices, such as laser printers, as well as data. Users can also use the LAN to communicate with each other, by sending e-mail or engaging in chat sessions.

There are many different types of LANs Ethernets being the most common for PCs. Most Apple Macintosh networks are based on Apple's AppleTalk network system, which is built into Macintosh computers.

The following characteristics differentiate one LAN from another:

topology : The geometric arrangement of devices on the network. For example, devices can be arranged in a ring or in a straight line.
protocols : The rules and encoding specifications for sending data. The protocols also determine whether the network uses a peer-to-peer or client/server architecture.
media : Devices can be connected by twisted-pair wire, coaxial cables, or fiber optic cables. Some networks do without connecting media altogether, communicating instead via radio waves.
LANs are capable of transmitting data at very fast rates, much faster than data can be transmitted over a telephone line; but the distances are limited, and there is also a limit on the number of computers that can be attached to a single LAN.

A local area network (LAN) is a computer network covering a local area, like a home, office, or group of buildings. Current LANs are most likely to be based on switched IEEE 802.3 Ethernet, or on Wi-Fi technology running at 10, 100 or 1,000 Mbit/s.

The defining characteristics of LANs in contrast to WANs (wide area networks) are: their much higher data rates; smaller geographic range; and that they do not require leased telecommunication lines.
