Study Notes
Network Topology
- Refers to the arrangement of nodes, links, and devices in a computer network
- Defines how components are connected and interact with each other
Types of Network Topology
- Point-to-Point Topology: simplest communication between two nodes, one sender and one receiver
- Mesh Topology:
- Every device is connected to another device via a particular channel
- Protocols used: AHCP, DHCP, etc.
- Example: internet backbone, military communication systems, and aircraft navigation systems
- Star Topology:
- All devices connected to a single hub through a cable
- Hub is the central node
- Types of hubs: passive, active (with repeaters)
- Examples: local area network (LAN) in an office, wireless networks
- Bus Topology:
- Every computer and network device connected to a single cable
- Bi-directional, multi-point connection, and non-robust
- Protocols used: MAC, TDMA, Pure Aloha, CDMA, Slotted Aloha, etc.
- Examples: Ethernet LAN, cable television networks
- Ring Topology:
- Forms a ring connecting devices with exactly two neighboring devices
- Uses repeaters to prevent data loss
- Example: ring topology with 100 nodes, data passes through 99 nodes to reach the 100th node
