NETWORK TOPOLOGY

WHAT IS NETWORK TOPOLOGY ?

• Network topology is the layout of the nodes(device) in a communication network.

PHYSICAL TOPOLOGY -  connected to the network through the actual cables that transmit data
LOGICAL TOPOLOGY - path that data travels between computers and network 

BUS TOPOLOGY

*Each device connected to single central cable (backbone) through T-Connector

ADVANTAGES :

• -Inexpensive
• -Easy to install
• -Not effect other device if one device is damage

DISADVANTAGES :

• Dificult to find the problem if the network shut down
• A break in cable will prevent all system from access to network

STAR TOPOLOGY

*All devices on the network connect to a central device(star)

ADVANTAGES :

• Easy to add new devices
• Easy to monitor and troubleshoot

DISADVANTAGES :

• If hub fails,whole network will inoperable
• require more cable than bus topology
• expensive 

RING TOPOLOGY

*A cable forms a closed loop(ring) with all devices arranged along the ring

ADVANTAGES :

•  Cable fault easy to located and easy to troubleshoot
• Easy to install

DISADVANTAGES :

• A break in ring will disable the entire network
• data packets is passing through every computer that make it slower.
