What is Backbone?
In computing, a backbone is a central network structure that provides connectivity between multiple networks or subnetworks. A backbone typically consists of a high-capacity network connection that can handle a large amount of data traffic and that is used to link together smaller networks or devices.
Backbones are often used to connect different parts of a large network, such as different buildings or departments within an organization. They can be implemented using various technologies, including wired or wireless connections, and may be based on a variety of networking protocols.
In a hierarchical network architecture, the backbone is typically at the top level and serves as the primary connection between the various lower-level networks or subnetworks. It is responsible for routing data traffic between these networks and ensuring that data can be transmitted efficiently and reliably between different parts of the network.
