Star Topology:
A star topology is designed with each node (file server, workstations, and peripherals) connected directly to a central network hub, switch. Data on a star network passes through the hub, switch, before continuing to its destination. The hub, switch, manages and controls all functions of the network. It also acts as a repeater for the data flow.
Advantages of a Star Topology :
- asy to install and wire.
- No disruptions to the network when connecting or removing devices.
- Easy to detect faults and to remove parts.
Disadvantages of a Star Topology :
- Requires more cable length than a linear topology.
- If the hub, switch fails, nodes attached are disabled.
- More expensive than linear bus topologies because of the cost of the hubs, etc.
Tree topology :
A tree topology combines characteristics of linear bus and star topologies. It consists of groups of star-configured workstations connected to a linear bus backbone cable. Tree topologies allow for the expansion of an existing network.
Advantages of a Tree Topology:
- Point-to-point wiring for individual segments.
- Supported by several hardware and software vendors.
Disadvantages of a Tree Topology:
- Overall length of each segment is limited by the type of cabling used.
- If the backbone line breaks, the entire segment goes down.
- More difficult to configure and wire than other topologies.
