pHYSICAL TOPOlogy
WHat is a physical topology
- The topology of a network describes the way in which the devices (nodes) are connected.
- A node is any device that is connected to the network, including computers, printers, hubs, switches and routers.
- All nodes are able to both receive and transmit using the defined network protocols. Nodes are connected to each other via transmission media, either wired cable or wireless.
- Physical topology— the physical layout of devices on a network and how the cables and wires connect these devices.
tYPES OF PHYSICAL TOPOlogY
To find out more click the links below:
Physical Star Topology — The central node is the device that connects all outlying nodes such that they can transmit and receive packets to and from each other node.
|
Physical Bus Topology — it is when all nodes are connected to a single backbone.
|
Physical Ring Topology — each node connects to exactly two other nodes.
|
Physical Hybrid Topology -- uses a combination of connected bus, star and ring topologies
