logical bus topology

A network topology in which all nodes receive the data transmission at the same time, regardless of the physical wiring layout of the network.

ring topology facts

Installation requires careful planning to create a continuous ring. Isolating problems can require going to several physical locations along the ring. A malfunctioning node or cable break can prevent signals from reaching nodes further along on the ring.

Bus Topology

Network configuration wherein all computers connect to the network via a central bus cable.

logical ring topology

Network topology in which each node receives data only from its upstream neighbor and re transmits data only two it's downstream neighbor, regardless of the physical layout of the network.

logical star topology

Network topology where a central device polls each node to see if it needs to transmit data. The central device also controls how long a node has access to the cable.

Ring Topology

Network topology which connects one computer to another in a continuous loop

bus topology facts

Signals travel from one node to all other nodes. A device called a terminator is placed at both ends of the trunk cable. Terminators absorb signals and prevent them from reflecting repeatedly back and forth on the cable. It can be difficult to isolate cabling problems.

Physical topology

The way a network is physically wired. (road)

Logical Topology

The way data is transferred on the network (traffic laws)

Star Topology

network topology in which all host machines are connected to a central hub or switch

bus topology terminator

absorb signals on bus network and prevent them from reflecting repeatedly back and forth on cable.

mesh topology facts

are created using point-to-point connections. This increases the network's fault tolerance because alternate paths can be used when one path fails. Two variations of mesh typologies exist: Partial —Some redundant paths exist. Full —Every node has a point-to-point connection

Network Topology

categorizes networks based on the physical and logical relationship among devices.

Partial Mesh Topology

consists of at least two machines with redundant connections. a physical connection between devices to every other device is not required

Mesh Networking Topology

each device on the network has a point-to-point connection to every other device on the network . (Possible with Wireless networks)

star topology facts

most popular type of topology for a LAN. With a star: All network connections are located in a single place, which makes it easy to troubleshoot and reconfigure. Nodes can be added to or removed from the network easily. Cabling problems usually affect only one node.
