The largest computer network in the world is the Internet. Let’s dissect that:
Any collection of linked computing resources with the ability to send or receive data is referred to as a computer network. A computing device isn’t only a computer; it might be a tablet, a phone, or even a sophisticated sensor if it can execute software.
Two devices make up the simplest computer network.
Such a network simply needs to consider a few issues, such as how to physically link the two devices and how to deliver data via the physical connection in a manner that both devices can comprehend.
There is now more complication. How can each gadget distinguish between data intended for them and data intended for their neighbor?
This straightforward network requires an addressing scheme.
Jumping to six devices now. Six devices can be linked in a computer network in a variety of ways.
Each of those configurations represents a unique network topology, and each topology has pros and cons.
Imagine how a bit of data would go through one of those bigger networks. What course will it follow? How does it decide which path is the best when there are several options?
Routing strategies become more crucial as networks get bigger. In a path, there isn’t much of a difference between two and three stops, but there is a significant difference between 20 and 300 stops.
