A link is formed by connecting two or more devices, whereas a topology is formed by connecting two or more links. The arrangement of a computer network is referred to as topology. Network topology is a graphical representation of electric circuits. endobj 2 3 Network topology refers to the physical or logical layout of a network. Ring Topology: A local-area network whose topology is a ring. • Data on a star network passes through the hub, switch, or concentrator before continuing to its destination. Peer to Peer: In this relationship, all the devices in the network have equal status in sharing the link. The intermediate nodes repeat (re transmit) the data to keep the signal strong. Assistant Professor, Department of CSE, Bengal Institute of Technology and Management, Santiniketan The section 2 is a brief description of physical topologies. It is develops a P2P (point-to-point) connection between all the devices of the network. Expansion can be as simple as linking in an additional Star Network Topology onto the bus. /N 3 • Common topologies: –Bus, ring, star, mesh and wireless. So although it’s important to understand the layers, it’s also important not to be too pedantic about them. Although geographical sites can appear on the map, the purpose of the map is to show the geometry of the network, The CWM topology subsystem has been redesigned in Release 11 of CWM to provide more efficient navigation, modularity and scalability. when talking about network topology, we’re mostly interested in the bottom few layers. A star topology generally consists of a central hub. One can think of a topology as a network's virtual shape or structure. This type of network is easy to install and manage. The logical network topology describes how the information flows through the network. A topology is a map of an internetwork that indicates network segments, interconnection points, and user communities. ?���:��0�FB�x$ !���i@ڐ���H���[EE1PL���⢖�V�6��QP��>�U�(j There are numerous ways a network can be arranged, all with different pros and cons, and some are more useful in certain circumstances than others. This main cable or bus forms a common medium of communication which any device may tap into or attach itself to via an interface connector. Download free network topologies tutorial course material and training in PDF file under 4 pages by Maninder Kaur.
