The internet is a giant computer network, linking billions of machines together with underground cables. When you use it, you send messages via those cables asking for data stored on other machines. To make this possible, your computer and the computer you want to talk to need to speak the same language, so there’s a set of rules that everyone agrees to use.
These are called TCP/IP, which stands for Transmission Control Protocol/Internet Protocol. TCP/IP makes the internet work a bit like a postal system. There’s an address book that contains the identity of every device on the network and a set of standard envelopes for packaging up data. The envelopes must carry the address of the sender, the address of the recipient and details about the information packed inside.
