To understand networking, let’s first ask…

What is a network?

A network is simply collection of devices (e.g. — computers, printers, cell phones, TVs) that can communicate with one another.

For these devices to communicate and share information, they need to be connected with each other through cables and/or wifi.

The sender and receiver need to speak the same language. They need to agree on how to handle the information being transmitted.

This is called a protocol. A protocol is the set of instructions that defines how to handle the information being transmitted.

Networking is simply how those devices are connected with one another.

How does information get from one device to another over the internet?

For our purposes, let’s use two computers connecting to one another.

Computer A ←→ Computer B

The information on Computer 1 needs to be broken down into bite sized pieces before it can be shipped over a network.
