network architecture & topologies

TASK 1: UNDERSTANDING OF LAN TECHNOLOGIES

LAN or local area network could be stated as a kind of computer network in which computers are inter-connected in a way by which information be exchanged, inter-communication,n, and resource sharing can be implemented. In simple terms, it is a network that allows multiple users to access the same resources of a system, regardless of the physical location of the user or computer resources. The primary usage of LAN architecture is implemented in small areas like schools, offices, or colleges. In LAN computer network architecture, each user can receive and send data addressed to it (Trulove, 2005). Various types of LAN topologies are available and are shared below:

STAR TOPOLOGY:

In this type of topology, every computer or system is straightly connected to a custom centralized node. The central station also known as Star Coupler carries two point-to-point links, in which one does work for transmission and one is used for receiving. The basic features of the star network include, Firstly it is quite expensive to implement. Secondly,y the speed is quite fast as every node has its particular cable. Thirdly if a cable gets busted then only a single computer gets affected. The whole architecture is completely dependent on the central device. It is the most general network topology (LocalArea Network k(LAN), 2013).

BUS TOPOLOGY:

In this type of LAN topology, we design a long centralized cable that looks like a bus is utilized to interconnect the entire computer or the nodes altogether. Every computer carries a short cable which is inter-joined to the central cable or we can say links to the bus. The salient features of LAN are: Firstly its implementation is very cheap since a lesser amount of cables is required. Secondly,y it is fairly slow as all computers utilize the same cable for the transfer and reception of information and data. There can be interruptions if the central cable gets damaged (Chia
