Computer and Network Hardware - Assignment Example

Computer and Network Hardware Use of switches in a network A network switch refers to a networking device usedto link network devices. It comprises of a multiport that can hold a number of networks (Lewis, 2008). The use of switches in a network is necessary for effective control of the network. It is through the network switch that layering of data in different routes is possible through the data cables. The switch also allows reception of telecommunication message and transmission of the message to the required device (Lewis, 2008).

RoutersA router is a physical device joining a number of networks both wired and wireless. A router is necessary in a network in that they are the paths through which creation of layer 3 takes place (Lammle, 2008). Layer 3 refers to the gateway through which the data transmitted in a network operates and this mainly takes place in OSI model. Routers make use of Internet Protocol commonly known as IP address to pass data across the network. Routers are common in Local Area Networks (LAN) (Lammle, 2008).

Difference between a collision domain, a broadcast domain, and network segmentationA collision domain is where collision of data packets takes place on a shared medium mostly in Ethernet networking (Lammle, 2008). On the other hand, a broadcast domain is where any connected device to the network is capable of transmitting data to the other. In a broadcast domain, the data does not have to pass through a router. Finally, a network segment refers to any section of a workstation network depending on the devices used in the network.

Method of segmentationLAN segmentation is one of the common methods of creating collision domain (Medhi, 2007). The configurations depend on networks needed. With LAN, it is possible to extend the network and isolate faulty networks. It also helps to improve the network security and applicable in creating network domains (Medhi, 2007). LAN segmentation makes of bridges, network switches and routers in configuring the required network. ReferencesLewis, W., Cisco Networking Academy Program., & Cisco Systems, Inc. (2008).
