this week the topic was about
DEFINITION: the study of the arrangement or mapping of the elements of a network
TYPES OF PHYSICAL TOPOLOGY
=star wired ring
> LINEAR BUS
-A linear bus topology consist of a main run of cable with a terminator at each end
-All nodes (file server, workstation, and peripherals) are connected to the linear cable.
Advantages of a Linear Bus Topology
- Easy to connect a computer or peripheral to a linear bus.
- Requires less cable length than a star topology.
Disadvantages of a Linear Bus Topology
- Entire network shuts down if there is a break in the main cable.
- Terminators are required at both ends of the backbone cable.
- Difficult to identify the problem if the entire network shuts down.
- Not meant to be used as a stand-alone solution in a large building.
-each node (file server, workstations, and peripherals) connected directly to a central network hub, switch, or concentrator.
Advantages of a Star Topology
- Easy 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, or concentrator fails, nodes attached are disabled.
- More expensive than linear bus topologies because of the cost of the hubs, etc.
> STAR WIRED RING
- Looks like star topology.
- the MAU (multistation access unit) of a star-wired ring contains wiring that allows information to pass from one device to another in a circle or ring.
- a combination of linear bus and star topology
- star-configured workstation connected to a linear bus backbone
- 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 venders.
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.
- each of the system is connected to its respective neighbor forming a ring.
- does not require termination.
- there is no beginning and end point.
that's all from me >.<
