Final answer:
Network topologies like point-to-point, hub and spoke, or mesh are layouts used in computer networks. Point-to-point is simple and direct, hub and spoke has a central control point, and mesh offers high redundancy and multiple pathways for communication.
Step-by-step explanation:
Types of Network Topologies
Network topologies refer to the layout or organizational hierarchy of interconnected nodes of a computer network. Different network topologies serve various purposes and are used based on the needs and resources of the organization or structure that requires them.
Point-to-Point Topology
A point-to-point topology is the simplest type, involving a direct connection between two nodes. This topology is frequently used for dedicated links in a network, such as a connection between a computer and a printer, or for long-distance communication via a leased line.
Hub and Spoke Topology
A hub and spoke topology, also known as a star topology, involves a central node (the hub) to which all other nodes are connected (the spokes). This design is commonly employed in corporate networks where central control and simplicity are crucial.
Mesh Topology
In a mesh topology, every node is connected to every other node in the network, providing multiple pathways for data to travel. Mesh networks are robust, offering high levels of redundancy and reliability, suitable for networks where communication failure is not an option, such as in military applications.
