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

disadvantage is that a mesh topology requires more cables. Complication of implementation is another disadvantage. Bus Topology With a bus topology all node on the network shares a common bus‚ whereas‚ the nodes also shares communication. Because the bus topology is sharing with others‚ only one device when transmitting is done one at a time. The bus topology connects each of the nodes to a single line. The single line is typically a coax cable. A protocol determines which computer is to transmit
