The Internet is a global wide area network that connects computer systems
across the world. It includes several high-bandwidth data lines that comprise
the Internet "backbone." These lines are connected to major Internet hubs that
distribute data to other locations, such as web servers and ISPs.
The World Wide Web (WWW), commonly known as the Web, is an information
system where documents and other web resources are identified by Uniform
Resource Locators (URLs, such as https://www.example.com/), which may be
interlinked by hypertext, and are accessible over the Internet. The resources
of the WWW may be accessed by users by a software application called a web
browser.
Email (electronic mail) is the exchange of computer-stored messages by
telecommunication. Email messages are usually encoded in American Standard
Code for Information Interchange (ASCII) text. However, you can also send
nontext files -- such as graphic images and sound files -- as attachments sent
in binary streams. Email was one of the first activities performed over the
internet and is still the most popular use. A large percentage of the total
traffic over the internet is email. Email can also be exchanged between online
service provider users and in networks other than the internet, both public
and private.
Email can be distributed to lists of people, as well as to individuals. A
shared distribution list can be managed by using an email reflector. Some
mailing lists enable you to subscribe by sending a request to the mailing list
administrator. A mailing list that is administered automatically is called a
list server.
Internet fax, e-fax, or online fax is the use of the internet and internet

connection and a fax machine.

File transfer is the transmission of a computer file through a
