3.1.3 Computer Network Topologies
Network Topology is a network specification that determines the network arrangement, connecting the senders and receivers through lines of connection. Topologies are of both physical and logical aspect of the network. The physical topology describes the network’s physical wiring layout or shape. The logical topology describes the path through which the data moves. Both logical and physical topologies could be same or different in a same network. The physical and logical topologies do not have to be the same common topologies. They include a star pattern, ring pattern, and bus pattern.
• Bus Topology
• Star Topology
• Ring Topology
• Mesh Topology
• Tree Topology
• Hybrid Topology
Point to Point
Point-to-point networks contain exactly two hosts such as computer, switches, routers, or servers connected back to back using a single piece of cable. The receiving end of one host is connected to the sending end of the other host. If the hosts are connected point-to-point logically, then may have multiple transitional devices. But the end hosts are unaware of the underlying network and see each other as if they are connected directly. …show more content…
Here, each node is connected to the network cable with a T-connector or a tap. A bus network is easy to implement but can be unreliable. The reason is that the entire bus fails if there is a break in the wire. Also, both ends of the shared channel have line terminator. The data can be sent through only one direction. When it reaches the extreme end, the terminator eliminates the data from the line. Figure 3.1.9: Common Bus
