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.

A webform, web form or HTML form on a web page allows a user to enter data that is sent to a server for processing.

Forms can resemble paper or database forms because web users fill out the forms using checkboxes, radio buttons, or text fields.

For example, forms can be used to enter shipping or credit card data to order a product, or can be used to retrieve search results from a search engine.

Various anti-spam techniques are used to prevent email spam (unsolicited bulk email).

No technique is a complete solution to the spam problem, and each has trade-offs between incorrectly rejecting legitimate email (false positives) vs.

not rejecting all spam (false negatives) – and the associated costs in time and effort.

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.
