Types of LAN Typologies by Mind Map: Types of LAN Typologies

1. Ring

1.1. Computer are connected in a ring (circle).

1.2. A type of computer configuration where each network computer and device connect to each other forming a large circle.

1.3. Data is transmitted from node to node in one direction.

1.4. Advantages : There are no collisions , no terminators are needed, easy to locate and correct problems with devices and cable.

1.5. Disadvantages : requires more cable than a bus network, expensive, a break in the cable brings the entire network down and complex.

2. Bus

2.1. A Bus topology consists of a main run of a cable with a terminator at each end. All nodes are connected to the linear cable.

2.2. Terminator – eliminate signal feedback /signal loss.

2.3. Without the terminator, the electrical signal that represent the data would reached the end of cooper wire and bounce back, causing errors on the network.

2.4. Common speeds are 10, 100 and 1000Mbps.

2.5. Advantages: inexpensive to install, can easily add more workstation, easy to install.

2.6. Disadvantages : If the cable break down the network is down, access time and network performance degrade as devices are added to the network.

3. Star

3.1. All computer are connected to a central point such as hub or switch

3.2. The most common topology used today

3.3. Data on a star topology passes through the hub or switch before continuing to its destination.

3.4. Advantages : Cable failure will not disrupt the network, easy to install and wire.

3.5. Disadvantages : Single point of failure, require more cable length.


4.1. A star network with an additional networking device connected to the main networking device.

4.2. It is a network cable connects to one switch, and then several other switches connect to the first switch


5.1. Combination of any two or more different topologies.

5.2. The most commonly used topologies are Star-Bus or Star-Ring.

5.3. Advantages : If a computer fails, it will not affect the rest of the network, extremely flexible.

5.4. Disadvantages : If the central component, or hub, that attaches all computers in a star, fails, no computer will be able to communicate.


6.1. All computer are connected to every other computer on the network

6.2. Rarely used on a Local Area Network (LAN)-The topology of the Internet.

6.3. The length cable required is quite higher as compared to other topologies.

6.4. Advantages : Very redundant, No disruption when expanded, Data transfer is faster.

6.5. Disadvantages : Expensive.Requires a lot of cable and network interface cards.
