Short Message Service (SMS) is a text messaging service component of most telephone, World Wide Web, and mobile telephony systems.

It uses standardized communication protocols to enable mobile phone devices to exchange short text messages.

An intermediary service can facilitate a text-to-voice conversion to be sent to landlines.

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 website is a collection of related web pages, including multimedia content, typically identified with a common domain name, and published on at least one web server.

A website may be accessible via a public Internet Protocol (IP) network, such as the Internet, or a private local area network (LAN), by referencing a uniform resource locator (URL) that identifies the site.
