So have you ever sat down to think, how does the internet even work? How does messages move from one computer to another? And if millions of people are actively sending messages to-and-fro over the internet then how does every message knows where to go?
Well let start off by saying that every communication over the internet consists of several things like the data which it carrying and the destination address on the internet where the message is gonna be delivered, all of this is what known as packets.
A packet is simply just like an envelope of data sent over the internet with the address of the sender on the outside. A packet is also limited, in the sense that the if the message been sent is too long, it gonna be divided into several packets.
Computer connected on the internet are always assigned a specific set of numbers called it internet protocol address IP address, and that how a packet knows what computer it meant for.
