A network topology in which network nodes are connected in a circular configuration. Each nodes Examines the data sent through the ring and passes on data not addresses to it.this iz ring topology A network layout or design in which each node is connected to a central hub. The hub establishes, maintains and terminates all connections between the nodes. In a LAN, the hub is likely to be a workstation, whereas in larger multi-point networks the hub is more likely to a multiplexer.this is star topology jyoti bhubanesw3ar
Also called signal topology. Every LAN has a topology, or the way that the devices on a network are arranged and how they communicate with each other. The way that the workstations are connected to the network through the actual cables that transmit data -- the physical structure of the network -- is called the physical topology. The logical topology, in contrast, is the way that the signals act on the network media, or the way that the data passes through the network from one device to the next without regard to the physical interconnection of the devices. Logical topologies are bound to the network protocols that direct how the data moves across a network. The Ethernet protocol is a common logical bus topology protocol. LocalTalk is a common logical bus or star topology protocol. IBM's Token Ring is a common logical ring topology protocol. A network's logical topology is not necessarily the same as its physical topology. For example, twisted pair Ethernet is a logical bus topology in a physical star topology layout. While IBM's Token Ring is a logical ring topology, it is physically set up in a star topology.
in bus topology computers are connected with each other by a wire in a approximately strait manner..and if one computer stops working the whole network will stop. while in star topology every computer is connected with the host computer & much wire is require..and if any client computer tops working it will not effect the whole network.----ravi singh chauhan...7275974787
Computer network topologies refer to the physical or logical layout of devices and connections in a network. They define how nodes, such as computers, servers, or other devices, are arranged and how data flows between them. Common network topologies include bus, star, ring, mesh, tree, and hybrid configurations. In a bus topology, devices connect to a single central cable where data travels to each device. Star topologies use a central hub or switch to connect all devices, managing data distribution centrally. Ring topologies form a closed loop where data passes sequentially between connected devices. Mesh topologies offer redundancy with multiple interconnections, enhancing reliability. Tree topologies combine bus and star structures, while hybrid topologies integrate different types for flexibility. Each topology suits different network needs based on factors like scalability, fault tolerance, and performance requirements.
proxy server
a WAN network (wide area network).
Advantages:* Good performance * Reliable (if one connection fails, it doesn't affect others)* Easy to replace, install or remove hosts or other devicesDisadvantages:* Expensive to install * Extra hardware required
Packets will be prioritized according to IP precedence.

Token-based media access is a controlled media access method in which computers pass a special sequence of bits between them; only the node holding this token can transmit on the network. After transmitting its data, or if it has no data to transmit, a node passes the token to the next computer on the network. Neeraj
VIP (very important person) passes are given to a person that is afforded special privileges due to a relationship to a performer. These passes can be given to family members, or in some occasions bought.
ring topology uses token ring i.e one way communication which passes the token with header and Destination address into the network.If one client in the network just disconectd from the network then the the entire network collapse. For this problem FDDI is used for fault tolorence Where as ethernet works much efficiently in packet delivering
