Does a star topology have a server?
Does a star topology have a server?
With a star topology setup, each node (such as a computer) within your company or team is connected to one central network device (which could be a hub, a switch, or a computer) via a cable. The central network is the server, and the other devices are clients.
Which network topology is token based?
ring networks
A token-ring network is a local area network (LAN) topology that sends data in one direction throughout a specified number of locations by using a token.
How does Token Ring topology work?
A token-ring network arranges nodes in a logical ring, as shown below. The nodes forward frames in one direction around the ring, removing a frame when it has circled the ring once. The ring initializes by creating a token, which is a special type of frame that gives a station permission to transmit.
What is a star network connection?
A star network is a local area network (LAN) topology in which all nodes — personal computers (PCs), workstations or other devices — are directly connected to a common central computer that is often referred to as a hub. In the real world, a star network can consist of either wired or wireless connections.
Does a star network need a server?
Large networks using a star network topology are usually controlled by one or more servers . However, peer-to-peer networks can also have a star network topology.
How does a token bus network work?
Token bus is a network implementing a Token Ring protocol over a virtual ring on a coaxial cable. A token is passed around the network nodes and only the node possessing the token may transmit. If a node doesn’t have anything to send, the token is passed on to the next node on the virtual ring.
How does a ring network work?
In a ring network each device (workstation , server , printer) is connected to two other devices – this forms a ring for the signals to travel around. Each packet of data on the network travels in one direction and each device receives each packet in turn until the destination device receives it.
What is token topology in computer network?
The frames used to transfer from one host to another is called tokens. And this token is traveled in a logical ring, and the ring can be a workstation or server. This topology traverses the data in a medium where any data can be sent to any computer connected in a network called a contention-based access method.
What is token passing in computer network?
Token passing is a method of acknowledging a signal received by computer for transmitting the message to one another. So receiving end gets the data and passes the signal to the source with a signal as acknowledgment. The importance of the token ring topology is, the source sends an empty token with a message and address of the destination.
What are the advantages and disadvantages of token ring topology?
Below are the benefits & drawbacks of Token Ring Topology: Packet collision is reduced and the flow of data is managed in only one direction i.e. in the circular. High-speed data transfer between workstations. Easier maintenance of the network.
What is a token ring network?
A token ring network is a local area network (LAN) in which all computers are connected in a ring or star topology and pass one or more logical tokens from host to host. Only a host that holds a token can send data, and tokens are released when receipt of the data is confirmed. Click to see full answer.
