In a star topology, all devices are connected to a single central device such as a switch or a hub, which acts as a conduit to transmit messages.
Terminators are placed at both ends of a bus network to absorb signals and prevent them from bouncing back and causing interference, known as signal reflection.
A full mesh topology connects every node to every other node, ensuring that if one path fails, data can be rerouted through another path.
In a standard single-ring topology, data travels in one direction through each node; if one node fails, the loop is broken and communication stops.
A tree topology connects multiple star networks together, forming a parent-child relationship between nodes.
In a star topology, if one cable or device fails, the rest of the network remains functional, making it much easier to isolate and troubleshoot issues.
Full mesh topology requires n(n-1)/2 connections; as the number of nodes increases, the cabling requirements grow exponentially, making it impractical for large networks.
Since all devices share the same communication medium in a bus topology, adding more nodes increases the probability of data collisions and reduces overall bandwidth.
A bus topology uses a single backbone cable that connects all nodes, allowing them to share the transmission medium.
Token passing is the standard method in ring topologies where a 'token' is passed around; only the node with the token is allowed to transmit, preventing collisions.
A tree topology connects multiple star networks to a central bus backbone, effectively merging the traits of both.
The formula n(n-1)/2 determines the total number of unique physical connections needed to link every node to every other node.
Tree topology allows for hierarchical grouping, which makes isolating and managing faults within specific branches easier.
Hybrid topologies are designed to meet specific functional needs, scalability, and performance requirements by leveraging the strengths of different topologies.
In a tree topology, the failure of the root or main trunk backbone cable disconnects the entire network branches connected to it.
Partial mesh provides a balance between high reliability and cost-effectiveness by connecting critical nodes with redundant paths, unlike a full mesh.
Token Ring networks utilize a Multi-Station Access Unit (MAU) which physically looks like a star hub, but logically the data travels in a ring pattern.
Due to its hierarchical structure, tree topologies require substantial cabling to connect branches to the main trunk.
A daisy chain is a sequence of nodes connected together in a linear fashion, where each node is connected to the next.
The defining feature of a mesh topology is its multiple paths, allowing for self-healing and redundancy if one connection fails.
