Network Topology
The document discusses different network topologies. A star topology has all devices connected to a central hub. It is easy to install but the network is disabled if the hub fails. A bus topology connects all devices to a single cable. It requires less cable than a star but the whole network fails if the cable breaks. A ring topology forms a closed loop connecting all devices. Data transfer is simple but the network slows down as packets pass through all devices.

ppt on types of topology
Topology refers to the physical layout of a network including the arrangement of components like computers, peripherals, and cables. There are several common network topologies including bus, star, ring, tree, and mesh. Each has advantages and disadvantages related to things like ease of use, installation, troubleshooting, scalability, and fault tolerance. The document then provides more details on each individual topology type.
Bus topologoy
A bus topology connects each computer and network device to a single backbone cable. It works well for small networks and requires less cable than a star topology. However, it is difficult to troubleshoot individual devices if the network goes down, additional devices slow the network down, and damage to the main cable can cause network failure or splitting.

11 Data Link_Control
This document discusses various data link control protocols. It begins by explaining how data is packaged into frames at the data link layer, using framing techniques like fixed-size and variable-size framing. The key responsibilities of the data link layer are then introduced as flow control and error control. Several protocols are presented that implement these functions on both noiseless and noisy channels, including the simplest protocol, stop-and-wait protocol, and various automatic repeat request (ARQ) protocols. Worked examples demonstrate how these protocols operate in different scenarios.
Error control
Error control techniques allow for detection and correction of errors during data transmission. Error control is implemented at the data link layer using automatic repeat request (ARQ) protocols like stop-and-wait and sliding window. Stop-and-wait involves transmitting a single frame and waiting for an acknowledgment before sending the next frame. Sliding window protocols allow multiple unacknowledged frames to be transmitted by using frame numbers and acknowledging receipt of frames. These protocols detect errors when frames are received out of sequence and trigger retransmission of lost frames.

bus network ppt by pearl patel
A computer network allows computers to exchange data by connecting computing devices. There are different types of networks including ring, bus, star, and tree networks. A bus network connects nodes in a linear sequence using a single cable or bus. It has advantages like easy connection and less cable required but disadvantages like the entire network failing if the main cable is damaged. In a bus network, all nodes receive all traffic and each station has equal priority to transmit.
Network Topologies in computer networking
This document discusses various network topologies including bus, ring, star, tree, mesh, and hybrid topologies. For each topology, it provides a brief description and then lists advantages and disadvantages. Some key points covered include:
- A bus topology connects all nodes to a single backbone cable and broadcasts messages to all nodes. It has simpler configuration but signal interference can occur.
- A ring topology connects nodes in an endless loop with unidirectional data flow. It is more reliable than bus but a single node failure disrupts the whole network.
- A star topology connects all nodes to a central hub/switch. Troubleshooting is efficient but the hub is a single point of failure.

TOPOLOGy
- 2. Topology is a physical arrangement of connecting various computer for networking.
- 3.
- 4. Bus topology is the simplest type of network.It supports a small number of computers. In bus topology all computers are connected to a common communication medium, known as bus( central wire).
- 6. Simple and easy to use. Requires a small length of cable to connect computers. Less expensive. Easy to extend a bus, it allows more computers to join network. If one node fails, it does not affect the network. Difficult to troubleshoot. Only support small number of computers. If number of computers increases, network speed will slow down.
- 7. All computers in star topology are connected with a central device called HUB. Star topology is mostly used in client server networks.
- 9. Easy to maintain and modify network. Adding or removing computers can be done without disturbing the network. Findings faults become very simple. Single computer failure doesn’t bring down whole network. If the central hub fails ,the entire network breaks down. More expensive. Requires large length of cable to connect computers.
- 10. In this topology , each computer is connected to the next computer with the last one connected to the firs. Thus, a ring of computers is formed.
- 12. Less expensive than star topology. Every computer has equal access to the network. Failure of one computer in the ring can effect the whole network. Difficult to troubleshoot. Adding or removing computers effects the whole network.
- 13. It combines the characteristics of star and bus topologies. It consist of group of computers attached in star topology. The group connected to bus backbone cable.It is used for expansion of an existing network.
- 15. Support by several hardware and software vendors. Provides point-to-point wiring for individual segments. Length of each segment is limited by the type of cabling used. If the backbone line breaks, the entire segment goes down. Difficult to configure and wire than other topologies.
- 16. In mesh topology every device in the network is physically connected to every other device in network. A message can be sent on different possible paths from source to destination. Mesh topology improve performance. It is mostly used in wide area network.
- 17. Easy to troubleshoot. If one links becomes unusable, it does not harm the entire system. It eliminates the trafic problems. A full mesh network can be very expensive. Very difficult to install and configure.
