My project report is on ‘how network architecture has changed over the decade’. In this report‚ I’d be talking about different network architecture that has been adopted over the past years. I would as well put light upon early network architecture and the advantages and disadvantages of former and why and how latter architecture were needed and adopted. Network architecture is the design of communication network. It is the complete framework of computer network. The diagram of the network architecture

Exercise 2.3.1 LAN – Local Area Network – within a building MAN – Metropolitan Area network – larger than a LAN‚ smaller than a WAN PAN – Personal Area Network – less than 30 feet WAN – Wide Area Network – collection of LANs geographically spread over large distance Exercise 2.3.2 Network Topology – A drawing of a series of connected nodes via links‚ including descriptions. Exercise 2.3.3 It would take 1 (hop) message to send a message from node A to node B. It would take 3 (hop) messages

Different Types of Networks • Depending upon the geographical area covered by a network‚ it is classified as: – Local Area Network (LAN) – Metropolitan Area Network (MAN) – Wide Area Network (WAN) – Personal Area Network (PAN) Local Area Network (LAN) • A LAN is a network that is used for communicating among computer devices‚ usually within an office building or home. • LAN’s enable the sharing of resources such as files or hardware devices

amongst the buildings‚ which means we have to build a backbone to connect all three LANs. Before addressing the connectivity issues amongst the buildings‚ lets first look at the current topologies in each building; 2 Ethernet and token ring. I recommend going with Ethernet‚ it is a simpler topology‚ which has less room for errors. With 100 computers in each building I would recommend 100base-T Switched Ethernet LANs‚ in all three buildings. The type of circuit is dedicated point to point. In order
