Electronic mail, or email, is a method of exchanging digital messages between people using digital devices such as computers and mobile phones.

Email first entered substantial use in the 1960s and by the mid-1970s had taken the form now recognized as email.

Email operates across computer networks, which today is primarily the Internet.

Some early email systems required the author and the recipient to both be online at the same time, in common with instant messaging.

Today's email systems are based on a store-and-forward model.

Email servers accept, forward, deliver, and store messages.

Neither the users nor their computers are required to be online simultaneously; they need to connect only briefly, typically to a mail server or a webmail interface, for as long as it takes to send or receive messages.

A user is a person who uses a computer or network service.

Users generally use a system or a software product without the technical expertise required to fully understand it.

Power users use advanced features of programs, though they are not necessarily capable of computer programming and system administration.

Information is that which informs.

In other words, it is the answer to a question of some kind.

It is thus related to data and knowledge, as data represents values attributed to parameters, and knowledge signifies understanding of real things or abstract concepts.

As it regards data, the information's existence is not necessarily coupled to an observer (it exists beyond an event horizon, for example), while in the case of knowledge, the information requires a cognitive observer.

An online magazine is a magazine published on the Internet, through bulletin board systems and other forms of public computer networks.

One of the first magazines to convert from a print magazine format to being online only was the computer magazine Datamation.

A web directory or link directory is an online list or catalog of websites.

That is, it is a directory on the World Wide Web of (all or part of) the World Wide Web.

Historically, directories typically listed entries on people or businesses, and their contact information; such directories are still in use today.

A web directory includes entries about websites, including links to those websites, organized into categories and subcategories.

Besides a link, each entry may include the title of the website, and a description of its contents.

In most web directories, the entries are about whole websites, rather than individual pages within them (called "deep links").

Websites are often limited to inclusion in only a few categories.
