Network Topologies A computer physical network topology is the actual layout or physical design and intercon-nection of a computer network. A topology includes the cabling and devices that are part of the network. In the following sections you will learn about several different types of network topologies: B u s R in g S tar Mes h Ad-ho c
A star topology makes all nodes be directly connected to a single centralized node. This uses much fewer links than a fully connected network, but still allows all nodes to communicate within two hops.
Network Topologies. Topology - Physical and logical network layout. Physical – actual layout of the computer cables and other network devices. Logical – the way in which the network appears to the devices that use it. Common topologies: Bus, ring, star, mesh and wireless.
Network Topologies • Regular networks – Grids, rings, etc. • Real networks – Power-law topologies • Properties of real networks • Designing networks with particular properties
This lesson covered the following main topics: The function and operation of a hub, a switch, and a router. The function and operation of Layer 2 switching, Layer 3 switching, and routing. The OSI model. Functionality of LAN, MAN and WAN networks.
Lecture 9, 5/1/2017. Scribed by A. Santucci. 9 Network Topology. There are all kinds of ways that computers can be connected. Suppose each node a computer. The below is a su cient network. x -- x -- x -- x. |. -- x -- x -- x. Whats reasonable to assume about connectedness of network?
The most basic network topologies used in practice are trees, cycles, grids and tori. Many other suggested networks are simply combinations or derivatives of these.
