For WANs depending on the protocol the packets can be very different.
For LANs, the ring topology insists on special packets proceeded by a "token".

What is Ring topology and Star topology?
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
What is a logical network designtopology?
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.
What is the differences between ring topology and 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
A special computer that checks all communication that passes through it between a companies internal network is called?
proxy server
What is a network that passes between buildings?
a WAN network (wide area network).
Advantages of using star topology?
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
What happens to the priority of a packet marked with DSCP when it passes a router that only supports IP precedence?
Packets will be prioritized according to IP precedence.
What channel is the NFL draft on?
The first round is on ESPN and nfl network but rounds 2-7 are only on NFL network
What is token based media access?
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
What are passes?
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.
What advantages does token ring have over Ethernet?
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
