What is a network topology?
The arrangement or layout of different elements (links, nodes, etc.) in a computer network.
What is a bus topology?
A network setup where each computer is connected to a single central cable or backbone.
What is a star topology?
A topology where all devices are connected to a central hub or switch.
What is a ring topology?
A network configuration where each device is connected to two other devices, forming a circular data path.
What is a mesh topology?
A setup where each device is connected to every other device in the network.
What is a hybrid topology?
A combination of two or more different types of topologies.
Advantage of star topology?
Easy to install and manage; failure of one node doesn’t affect the rest of the network.
Disadvantage of star topology?
If the central hub fails, the whole network goes down.
Advantage of bus topology?
Easy to implement and requires less cable length.
Disadvantage of bus topology?
Difficult to troubleshoot and cable failure can affect the entire network.
Advantage of ring topology?
Data flows in one direction reducing the chance of packet collisions.
Disadvantage of ring topology?
Failure of a single node can disrupt the entire network.
Advantage of mesh topology?
Provides high redundancy and reliability.
Disadvantage of mesh topology?
Expensive to implement and maintain due to high cabling.
Where is hybrid topology commonly used?
In large organizations combining star, ring, and bus topologies.
What is a physical topology?
The actual physical layout of the devices and cables.
What is a logical topology?
The way data flows within a network regardless of its physical design.
What is a point-to-point topology?
A direct connection between two nodes.
What is a tree topology?
A combination of star and bus topologies with hierarchical structure.
How does data travel in a ring topology?
In a circular fashion from one node to the next until it reaches its destination.
