NETWORK FUNDAMENTAL Flashcards
WIRED NETWORK TOPOLOGY (12 cards)
What is a network topology?
It is the arrangement of different elements like links, nodes, clients and servers that make up a computer network
What are the main types of diagram used in network topology?
1 Physical topology
2 Logical topology
Define the term “Physical Topology”
Physical topology shows how the network devices and components are physically cabled and connected together
Define the term “Logical Topology”
It talks about how the traffic is actually going to flow in the network
What are the 6 different elements of a wired topology?
Point to point, bus, hub and spoke, ring, star, mesh
Define Point-to-Point Topology
It is the simplest form of network topology that involves a direct connection between 2 devices
Define “Ring Topology”
It is a network configuration where each device is connected to two other devices forming a circular data path
It is rarely used nowadays unless used with FDDI (Fiber Distributed Data Interface
0
Define “Bus Topology”
All the network devices are connected to a single central cable called the bus or backbone
Define “Star Topology”
It is one of the most used topology today. Each node of the network is connected to a centralized connection point that is usually a network switch, that switch can also be used as a repeater for the data flow
Define “Hub -and- spoke topology”
It is a variation of the star topology where the central node (hub) is connected to multiple nodes (spokes)
Define “Mesh topology”
It features a point-to-point connection between every single device on the network to create a robust and redundant network
What are the 2 types of mesh topology ?
1 Full mesh topology (Every node is connected to every other node)
x=n(n-1)/2 where x =number of connections , n=number of node
2 Partial mesh topology : Some node are organized in a full mesh scheme while others are connected to one or two devices in the network
