Essay on Choosing the Correct Networking Devices

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.

3: Network Layer: The use of network layer is switching and routing technologies. It demonstrates logical path and virtual circuits for transferring data from one node to

System extension used to make an association between two different PC systems or to gap one system into two. LAN switch-gives a focal association between two or more PCs on a system.

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.

It is in most cases used to connect multiple local area networks together to form a bigger network.

Bridge is a simple device that aids in interconnecting similar LAN's between local area networks that use identical protocols for the physical and data link layers in accordance with the IEEE 802.3 standards. As the devices connected to the bridge use the same protocols, the amount of processing required is minimal. Nowadays, routers are used more commonly to interconnect LAN’s as bridges are Layer 2 devices and pose almost no security while the router is a Layer 3 device and offers better Data Security.

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).

HUB - An Ethernet hub, active hub, network hub, repeater hub, multiport repeater or hub is a device for connecting multiple Ethernet devices together and making them act as a single network segment.

It is generally limited to a geographic area such as a writing lab, school, or building. Rarely are LAN computers more than a mile apart. In a typical LAN configuration, one computer is designated as the file server. It stores all of the software that controls the network, as well as the software that can be shared by the computers attached to the network. Computers connected to the file server are called workstations. The workstations can be less powerful than the file server, and they may have additional software on their hard drives. On many LANs, cables are used to connect the network interface cards in each computer; other LANs may be wireless.

Ethernet is typically the technology that is used to allow computers locally to communicate with one another. Computers that are close to each other they are connected by Ethernet.

The definition of a switch or network switch is a small device that joins multiple computers together, working on layer two of the OSI, to form a local

Switches are multilayer and can sit on the data link layer (layer 2) when processing and forwarding data, also on the network layer (layer 3) by using IP addresses when forwarding

The ability to send and receive data efficiently is the most important objective of networking computers.
