Computers need a common way to speak with one another.
Example
Think of it like talking on the telephone to someone who
doesn’t speak English and you don’t speak their language.
There’s no way to achieve a common understanding. You
may be able to guess a word here or there, but for the most
part, the conversation won’t work.
Computers can’t even guess a common word, so without a
language in common, that communication won’t happen.

Definition
The Hypertext Transfer Protocol (HTTP) is an application
protocol for distributed, collaborative, hypermedia
information systems1.
HTTP is a stateless protocol.
Example
When a host needs to customize the content of a web site
for a user, the web application must track the user’s
progress from page to page. The most common method for
solving this problem is sending and receiving cookies.
