Physical VS Logical Topologies Flashcards
Physical Topology
Is the physical layout of the device and cabling.
The primary physical topology categories are:
Bus, ring, star, and mesh
In a bus topology,
every workstation is connected to the main cable. Therefore, each workstation is directly connected to every other workstation in the network.
In a ring topology,
computers and other network devices are cabled together in a way that the last device is connected to the first to form a circle or ring. Each device is connected to exactly two neighbors and has no direct connection to a third.
Star topology
The most common physical topology. In this topology, a central cabling device connects the computers and other network devices.
Includes star and extended star topologies.
Physical connection is commonly made using twisted-pair wiring.
Mesh
In a mesh topology, every network device is cabled together with many other. Redundant links increase reliability and self-healing
The physical connection is commonly made using fiber or twisted-pair wiring.
The logical topology
Is the path along which data travels from one point in the network to another.
