NETWORK TOPOLOGY

What is Network Topology?

Network topology refers to the arrangement of devices (nodes), cables, and connections in a network and how data flows between them. It defines the structure of a network, both physically (how devices are connected) and logically (how data moves).

• In simple terms:
  • Physical topology = The actual layout of cables and devices.
  • Logical topology = The path data takes through the network.

Why is Network Topology Important?

• Performance: Determines speed and efficiency of data transfer.
• Scalability: How easily you can expand the network.
• Fault Tolerance: How well the network handles failures.
• Cost: Influences cabling and hardware requirements.
