Definition of point to point topology

“A point to point topology is a way of connecting two nodes (computer, laptop, mobile device, router, hub or switch) through a common medium. The medium can be wired cable or wireless satellite.”

In this topology, two nodes are usually placed near each other. The node can also be a router or hub. In the case of a router or hub, one connection is made between a computer and a router, hub or switch.

The communication between two nodes can be either simplex, half-duplex or full-duplex. In the simplex mode of communication, only one node can send data. In half-duplex, both devices (nodes) can send data but one at a time. In full-duplex, both devices can send data at a time.

The medium to make a connection can be either microwave-based, dedicated fibre or leased line.

Characteristics of point to point topology

Some features of point to point topology are:-

• High bandwidth
• Easy replacement of node
• Connection speed is fast
• Troubleshooting is easy
• Maintenance is easy
• Low latency rate
• The mode of connection is simple
• Low cost

Example of point to point topology

• The connection between TV and remote control
• The connection between AC and remote control
• Connecting two computers in LAN (local area network
• The connection between a router to a router
• The connection between a router and a workstation
