Study Notes
- Network topology is the arrangement of how computer systems or network devices connect.
- Topologies can define both the physical and logical aspects of a network.
- Physical topology refers to the layout of cables, computers, and peripherals.
- Logical topology describes how information passes between workstations.
Wired Physical Topologies
- Point-to-point networks have exactly two hosts, such as computers, switches, routers, or servers, connected back-to-back using a single cable.
- The receiving end of one host is often connected to the sending end of the other, and vice versa.
Bus Topology
- All devices share a single communication line or cable.
- This topology may encounter issues when multiple hosts send data simultaneously.
- It is a simple networking form where a device failure does not affect other devices.
- However, failure of the shared communication line can halt all other devices.
Star Topology
- Hosts connect to a central device (hub) via point-to-point connections.
- Data passes through the hub, switch, or concentrator before reaching its destination.
- The central hub manages all network functions.
- If the hub fails, connectivity to all other hosts is lost.
Ring Topology
- Each host connects to exactly two other machines, forming a circular network structure.
- When a host sends to a non-adjacent host, data travels through intermediate hosts.
- Adding a host may require only one extra cable.
Mesh Topology
- Each host connects to one or multiple hosts.
- Hosts have point-to-point connections with every other host.
- Some hosts may have point-to-point connections with only a few hosts.
Tree or Expanded Star Topology
- Combines linear bus and star topology characteristics.
- Star-configured workstations connect to a linear bus backbone cable.
- Tree topologies allow for network expansion and can be configured to meet specific needs.
Hybrid Topology
- A network design that incorporates more than one topology.
- Inherits benefits and drawbacks from all combined topologies.
