Introduction Network architecture is a combination of topology and protocols. In this paper‚ I will discuss topology‚ which is the defined as the shape of a network or how a network is laid out. Topology also consists of how the different components or nodes of a network are connected and how they communicate with each other. Topologies are either logical or physical. In addition‚ in the sections of this paper‚ I will compare and contrast some different conventional architecture and what types of
