Study Notes
Network Topologies
- Network cards used in ring topology computers can connect using coaxial cables or RJ-45 network cables.
Ring Topology
- All data flows in one direction, reducing packet collisions.
- No network server or central node is needed to control network connectivity.
- Data transfer between workstations is fast.
- Additional workstations can be added without impacting network performance.
- It performs better than bus topology with heavy network loads.
Disadvantages of Ring Topology
- If one connection or workstation in the ring is broken, the entire network is affected.
- Data must pass through each workstation, making it slower than star topology.
- Hardware needed to connect each workstation is more expensive than Ethernet cards and hubs/switches.
- Adding or moving devices in the ring can break the network.
Reliability of Ring Networks
- A single broken link can impede communication between nodes.
- Dual ring solutions improve reliability through redundancy, but increase deployment and maintenance costs.
- Token Ring protocol (IEEE 802.5) is a standardization related to ring topology.
Star Topology
- Every node connects to a central network device (hub, switch, or computer).
- The central network device acts as a server, and peripheral devices act as clients.
- This topology is popular for home networks, where devices connect to a local router.
- Star topologies are robust against link failure, only affecting hosts using those links.
Advantages of Star Topology
- Adding additional devices does not disrupt data transmission between other devices.
Mesh Topology
- Disadvantages include high implementation costs, difficulty in building and maintaining, and potential for redundant connections.
Ad-Hoc Topology
- Wireless ad-hoc networks enable user mobility and wireless connectivity.
- Each node dynamically establishes a communication link with nearby devices.
- Nodes have a dual role as mobile hosts and mobile routers.
- Ad-hoc networks do not rely on infrastructure and communicate over dynamically formed paths.
