Type Of Networks What It Is? How It Works

4)LAN (Local Area Network)-A LAN is a group of computers or devices connected together through a local network.LAN connections are usually very inexpensive.They are also usually very fast.LAN connections are usually within the same building.

A: LAN: LAN stands for Local Area Network. LAN is a network which cover a small area like colleges, schools or buildings.

A LAN is a ‘Local Area Network’. It is a small network of computers most often

Routers and switches will be utilized to route network signals to all areas of this large network. Telephony systems will be introduced to serve the VOIP located at each location to assist with communication needs. Wireless technologies will also be needed to assist with mobility and other devices such as printers, laptops, fax machines, etc. Lastly, a physical firewall will be enforced at each location to protect the network from internal and external intruders.

In the design, the topology used is a star topology. The computers in every office or classroom are linked to the central device known as the switch. The star topology leads to the expansion of the network without any disruption. This defines the use of a hub, a router or a switch to interconnect various computers together. All the workstations in this topology are connected with a connection of point-to-point to the central device. The data is first passed through the primary device before reaching the planned destination. Hub controls and manages the whole network. The hubs connect several nodes that are present in the star system. The hub acts as the signal booster (Elhakeem, 2010).

All stations are connected by cable or wireless to a central point, such as hub or a switch. If the central node is operating in a broadcast fashion such as a Hub, transmission of a frame from one station to the node is retransmitted on all of the outgoing links. In this case, although the arrangement is physically a star, it is logically a bus. In the case of the central node acting as switch, an incoming frame is processed in the node and then retransmitted on an outgoing link to the destination station. Ethernet protocols IEEE 802.3 are often used in the Star topology LAN.

A Star topology is the second type of topology represented. This topology is easy to install as well as being easy to expand by connecting additional nodes or devices. Faults are easily detected and parts are easy to remove. In a Start topology, when devices need to be added or removed, it does not cause disruptions to the network. This type of topology is used for many different applications, ranging from small to large networks. (FCIT, Univ. of Florida)

The user has the control to set up the network and it easier that client server. The user does not need special knowledge of setting up the network.

LAN- sub network that is made up of a group of clients plus servers which are under the control of one central security.

For example, the Sales and Marketing Division has a desktop computer for each of the account representatives. All of these computers are connected to a small local area network (LAN) that serves only the Sales and Marketing Division. The

Ideally, each local office would integrate its computers with a LAN, so that all employees would be able to share information, and resources such as printers. In case there are multiple buildings in an office (like in the corporate office), each building would have its own LAN, and the LANs could be connected by a Backbone Network.

A LAN is a network of computers in a specific area interconnect using a variety of network media. For example, WBHS LAN are all the computers connected to the WBHS network via Ethernet, Wi-fi or other. This is different from a WAN (Wide area network) which extends to a much wider area such as a town, city and country. LAN are usually more restricted in access and more numerous.

It is also called LAN and designed for small physical areas such as an office, group of buildings or a factory. LANs are used widely as it is easy to design and to troubleshoot. Personal computers and workstations are connected to

Local area networks (LANs). DEFINITION The concept of local area networks (LANs) is not new. It represents a logical development of computer technology. With the advent of microcomputers in the 1980s many office workers began bringing their own disks into work, compromising data integrity.
