What is topology? ▫ Physical connection of devices on the network. Three common types of multi-point topology: ▫ Bus. Network Topology. Fundamental layout of a network. - Describes the path or paths between any two points in the network. - Affects availability, speed and traffic congestion of the network. Logical topology. - Operational relationship between the various network components. Physical topology. - Actual layout of the network. By this type of topology, if one node goes faulty all nodes may be affected as all nodes share the same cable for the sending and receiving of information. The cabling cost of bus systems is the least of all the different topologies. Each end of the cable is terminated using a special terminator. [A]. Advantages: − Reliable in. arrangement of the network nodes. • The physical topology of a network refers to the configuration of cables, computers, and other peripherals. Different Types of Topologies. • Bus Topology. • Star Topology. • Ring Topology. • Mesh Topology. • Tree Topology. • Hybrid Topology. Bus Topology. • All the nodes (file server,. TOPOLOGIES. Before you start. Objectives: learn about different types of networks and on what basis it can be classified. Prerequisites: no prerequisites.. The first type of network that we will consider is called a Peer-to-Peer.. computer can have a large hard drive installed and everyone is allowed to put files on that.

In a home network, this can be such things as printers, a central storage drive, MP3 files,. While designing a network structure, network topologies, type, and design strategies play a very important role.. how they communicate with each other is determined by the network topology as shown in Fig. 2.1... of access on the network. Computer A will connect directly to computer B and will share all files with the. Chapter 2. Network Architectures. Abstract The networks have evolved significantly since the first network archi- tecture has been proposed. Lately, the architecture is seen more as a framework which specifies not only the network topology, network type, network components, and their functionality, but also presents data. provides an analytical study of different types of basic network topologies on the basis of their advantages, disadvantages and different factors which differentiate them. Key Words: Network Topology (Bus, star, ring, mesh and tree), advantage, disadvantage and hybrid topology. 1. INTRODUCTION. In computer network two. This supplement introduces some basic concepts of network topology as they apply to circuits consisting of resistors and independent sources. There is a voltage and a current associated with each of these two-terminal circuit elements. A circuit containing a total of E such elements involves a total of 2E circuit variables. C H A P T E R 2. LAN Topologies. The application in use, such as multimedia, database updates, e-mail, or file and print sharing, generally determines the type of data transmission. LAN transmissions fit into one of three categories: • Unicast. • Multicast. • Broadcast. Unicast. With unicast transmissions, a single packet is sent. Data files are shared. • Access can be limited. – Shared files stored on a server. – Software can be shared. • Site licenses. • Network versions. • Application servers.. 23. Network Topologies. • Topology. – Choice affects. • Network performance. • Network size. • Network collision detection. – Several different types. Topology refers to the way in which the network of computers is connected. Each topology is suited to specific tasks and has its own advantages and disadvantages. The choice of topology is dependent upon type and number of equipment being used, planned applications and rate of data transfer required, response time,. On a local level, this type of network may be called a workgroup in a LAN or an ad hoc wireless network when the local network itself is a decentralized wireless network. On WANs, the same term, peer-to-peer, is used to describe file and service sharing relationships in which each user also provides some small part. 1. IEEE 802.3ba – Nov 2007.

These are two examples of hybrid topology: Star-‐Bus: The star bus topology is combined with the linear bus in large. easy in this type of topology. Ring topology. 10. Advantages of Ring topology. This type of network topology is very organized; Performance is better than that of Bus topology; No need for network server to control the connectivity between workstations; Additional components do not affect the performance of network; Each computer has equal access to. Distances between nodes, physical interconnections, transmission rates, or signal types may differ between two different networks, yet their topologies may be identical.
