Types of network topology | Bus Topology | Ring Topology | Star Topology |
Definition | Network that consists of a single central cable to which all computers and other device connect. | Network where a cable form a closed loop ring with all computers and devices arranged along the ring. | All computers and other devices on the network connect to a central device thus forming a star, |
Description | - Each devices is connected to the bus cable through T-conncetor.
- Terminator is at each end to prevent signal from bouncing back and forth on the bus cable.
| | - Two types of devices that provide a commo central point tp all the other devices on the network are hub and switch.
|
Data transmit | Transmits
data and instructions as a series of signals in both direction where
all nodes receive recipient will accept the signals. | Data travels the entire ring in one direction and reach its destinatiom by using token. | Data transfers from on node to another node passing through hub/switch. |
Advantages | - Failure in one device does not affect the rest of the bus network.
- Inexpensive and easy to install.
- Devices can be without disturbing the rest of the network.
| - All computers have equal access to resources in the network.
- The uses of token enables all devices in ring topology to shre the network resources fairly.
- Cable faults are easily located
- The transmission of data is simple.
| - If one devices fails, only that device is affected.
- Devices can be added and removes with little distruption.
- Easy to troubleshoot.
|
Disadvantages | - The network will malfuntion if the backbone breaks down.
- The break will prevent all systems form accessing the network.
- The performance of network will slow down if more computers are added because of data collision.
| - Network malfuntion if device breaks down.
- Difficult to install.
- Data packets must pass through every computer making it slower.
| - Network will mulfuntion if hub/switch breaks down.
- Requires more cable cost than other topologies.
