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
This paper presents an introduction to Computer Network Topology. Definitions of Physical and Logical Topologies are provided. Additionally common Computer Network realizations of Physical Topologies are reviewed. This is followed by a discussion of Graph Theory and its relation to topological analysis.
What is a Topology? “The way in which the connections are made among all the network entities is called the topology of the network”. Network topology specifically refers to the physical layout of the network, e.g., the location of the computers and how the cable is run between them. The most common topologies are. Bus Star Ring Mesh.
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.
topologies are used in classic parallel computers or telecommunication networks, or more recently in the emerging area of peer-to-peer computing. The most basic network topologies used in practice are trees, cycles, grids and tori.
1. Exam objectives in this chapter. What Is a Network? Logical Network Topologies. Physical Network Topologies. Network Types. WHAT IS A NETWORK? The basic concept of networking is the difference between standing alone and being part of a group. Computers can also be standalone or part of a network.
The No Sweat Guide to Network Topology covers two main topics: • How to document your network topology • Some of the most common and useful topologies that you’ll run into By the time you get to the final pages, you’ll be able to map your network both logically and physically.
