Star, bus, ring, mesh, and tree are common network topologies. In a star topology, all devices connect to a central hub or switch. If the hub fails, the entire network fails. A bus topology uses a single cable to connect all devices in a line, allowing messages to travel in both directions until reaching the destination. A ring topology forms a continuous loop, with each device acting as a repeater to strengthen the signal as it passes to the next device. A mesh topology connects each device to every other device, providing redundancy so failure of one connection does not disconnect a device. A tree topology combines aspects of the bus and star topologies, allowing branching of servers to multiple sub-networks.
Bus topology uses a single, long cable called a backbone to connect all devices in a network. Nodes connect to the backbone using droplines and taps, where droplines connect devices to the cable and taps contact the cable's metallic core. Any computer on the bus topology can communicate with any other as they are all connected via the main cable. However, a fault in the backbone stops all transmission and network speed decreases with heavy traffic.
Network topology refers to the arrangement of elements like nodes, links, etc. in a computer or biological network. There are two types of network topologies - physical and logical. Physical topology refers to the physical layout and connections between devices, while logical topology shows how data flows regardless of physical design. There are eight basic network topologies - point-to-point, bus, star, ring, mesh, tree, hybrid, and daisy chain. Each topology has different characteristics that make it suitable for different network setups and needs.

Tree topology combines star and bus but relies heavily on the main cable.
Computer Network Topology By Team_Purple (Dept. English)Suman Mia
A network topology is the physical and logical arrangement of nodes and connections in a network.
Physical topology describes the layout of devices and cables, and logical topology describes how data is transmitted within the network regardless of the physical layout.
The document discusses different types of network topologies including bus, ring, star, tree, and mesh topologies. It also defines hub, switch, and router components. The key points are:
Bus topology has a main cable that devices connect to via drop lines, but has limits on distance and number of devices. Ring topology forms a circular path between devices but a single failure disrupts the whole network. Star topology uses a central hub that devices connect to for all communications, but a hub failure disables the whole system. Tree topology combines features of bus and star with a central root hub and branching lines to devices. Mesh topology connects every device directly to every other for redundancy but has high cabling costs. Hubs
This document discusses different network topologies, including physical and logical topologies. It describes point-to-point, bus, ring, star, tree, mesh, and hybrid topologies. Each topology is defined along with its advantages and disadvantages. For example, the star topology connects all computers to a central hub, making it easy to set up and modify but if the hub fails the whole network fails. The mesh topology connects each device directly to every other device, providing redundancy but requiring many cables. A hybrid topology combines two or more standard topologies to achieve flexibility and scalability but with increased complexity.

Topology
1. Types of Network Topology
Network Topology is the schematic description of a network
arrangement, connecting various nodes (sender and receiver)
through lines of connection.
BUS Topology
Bus topology is a network type in which every computer and
network device is connected to single cable. When it has exactly
two endpoints, then it is called Linear Bus topology.
2. Features of Bus Topology
1. It transmits data only in one direction.
2. Every device is connected to a single cable
Advantages of Bus Topology
1. It is cost effective.
2. Cable required is least compared to other network topology.
3. Used in small networks.
4. It is easy to understand.
5. Easy to expand joining two cables together.
3. Disadvantages of Bus Topology
1. Cables fails then whole network fails.
2. If network traffic is heavy or nodes are more the
performance of the network decreases.
3. Cable has a limited length.
4. It is slower than the ring topology.
RING Topology
It is called ring topology because it forms a ring as each computer
is connected to another computer, with the last one connected to
the first. Exactly two neighbours for each device.
Features of Ring Topology
4. 1. A number of repeaters are used for Ring topology with large
number of nodes, because if someone wants to send some
data to the last node in the ring topology with 100 nodes,
then the data will have to pass through 99 nodes to reach
the 100th node. Hence to prevent data loss repeaters are
used in the network.
2. The transmission is unidirectional, but it can be made
bidirectional by having 2 connections between each Network
Node, it is called Dual Ring Topology.
3. In Dual Ring Topology, two ring networks are formed, and
data flow is in opposite direction in them. Also, if one ring
fails, the second ring can act as a backup, to keep the
network up.
4. Data is transferred in a sequential manner that is bit by bit.
Data transmitted, has to pass through each node of the
network, till the destination node.
Advantages of Ring Topology
5. 1. Transmitting network is not affected by high traffic or by
adding more nodes, as only the nodes having tokens can
transmit data.
2. Cheap to install and expand
Disadvantages of Ring Topology
1. Troubleshooting is difficult in ring topology.
2. Adding or deleting the computers disturbs the network
activity.
3. Failure of one computer disturbs the whole network.
STAR Topology
In this type of topology all the computers are connected to a
single hub through a cable. This hub is the central node and all
others nodes are connected to the central node.
6. Features of Star Topology
1. Every node has its own dedicated connection to the hub.
2. Hub acts as a repeater for data flow.
3. Can be used with twisted pair, Optical Fiber or coaxial cable.
7. Advantages of Star Topology
1. Fast performance with few nodes and low network traffic.
2. Hub can be upgraded easily.
3. Easy to troubleshoot.
4. Easy to setup and modify.
5. Only that node is affected which has failed, rest of the nodes
can work smoothly.
Disadvantages of Star Topology
1. Cost of installation is high.
2. Expensive to use.
3. If the hub fails then the whole network is stopped because all
the nodes depend on the hub.
4. Performance is based on the hub that is it depends on its
capacity
8. MESH Topology
It is a point-to-point connection to other nodes or devices. All the
network nodes are connected to each other. Mesh has n(n-
1)/2 physical channels to link n devices.
There are two techniques to transmit data over the Mesh
topology, they are :
1. Routing
2. Flooding
MESH Topology: Routing
In routing, the nodes have a routing logic, as per the network
requirements. Like routing logic to direct the data to reach the
destination using the shortest distance. Or, routing logic which
has information about the broken links, and it avoids those node
etc. We can even have routing logic, to re-configure the failed
nodes.
9. MESH Topology: Flooding
In flooding, the same data is transmitted to all the network nodes,
hence no routing logic is required. The network is robust, and the
its very unlikely to lose the data. But it leads to unwanted load
over the network.
Types of Mesh Topology
1. Partial Mesh Topology : In this topology some of the
systems are connected in the same fashion as mesh
topology but some devices are only connected to two or
three devices.
2. Full Mesh Topology : Each and every nodes or devices are
connected to each other.
Features of Mesh Topology
1. Fully connected.
2. Robust.
10. 3. Not flexible.
Advantages of Mesh Topology
1. Each connection can carry its own data load.
2. It is robust.
3. Fault is diagnosed easily.
4. Provides security and privacy.
Disadvantages of Mesh Topology
1. Installation and configuration is difficult.
2. Cabling cost is more.
3. Bulk wiring is required.
TREE Topology
It has a root node and all other nodes are connected to it forming
a hierarchy. It is also called hierarchical topology. It should at
least have three levels to the hierarchy.
11. Features of Tree Topology
1. Ideal if workstations are located in groups.
2. Used in Wide Area Network.
Advantages of Tree Topology
1. Extension of bus and star topologies.
12. 2. Expansion of nodes is possible and easy.
3. Easily managed and maintained.
4. Error detection is easily done.
Disadvantages of Tree Topology
1. Heavily cabled.
2. Costly.
3. If more nodes are added maintenance is difficult.
4. Central hub fails, network fails.
HYBRID Topology
It is two different types of topologies which is a mixture of two or
more topologies. For example if in an office in one department
ring topology is used and in another star topology is used,
connecting these topologies will result in Hybrid Topology (ring
topology and star topology).
14. 2. Inherits the advantages and disadvantages of the topologies
included
Advantages of Hybrid Topology
1. Reliable as Error detecting and trouble shooting is easy.
2. Effective.
3. Scalable as size can be increased easily.
4. Flexible.
Disadvantages of Hybrid Topology
1. Complex in design.
2. Costly.
