5. World Wide Web
“The World Wide Web (“WWW” or simply the
“Web”) is a global information medium which users
can read and write via computers connected to the
Internet. The term is not a synonym for the Internet
itself. The Web is a service that operates over the
Internet, as e-mail does. The history of the Internet
dates back significantly further than that of the
World Wide Web.

Hierarchical distributed naming system
for computers, services, or any resource

special purpose computer that provides this
service to web users.

When IP addressing first came out, everyone thought that there were
plenty of addresses to cover any need. Theoretically, you could
have 4,294,967,296 unique addresses (232)
