Transport Layer Security (TLS) and its predecessor, Secure Sockets Layer (SSL), both frequently referred to as "SSL", are cryptographic protocols that provide communications security over a computer network.

Several versions of the protocols find widespread use in applications such as web browsing, email, Internet faxing, instant messaging, and voice-over-IP (VoIP).

Websites use TLS to secure all communications between their servers and web browsers.

The World Wide Web (abbreviated WWW or the Web) is an information space where documents and other web resources are identified by Uniform Resource Locators (URLs), interlinked by hypertext links, and can be accessed via the Internet.

English scientist Tim Berners-Lee invented the World Wide Web in 1989.

He wrote the first web browser computer program in 1990 while employed at CERN in Switzerland.

The Web browser was released outside of CERN in 1991, first to other research institutions starting in January 1991 and to the general public on the Internet in August 1991.

In computing, a server is a computer program or a device that provides functionality for other programs or devices, called "clients".

This architecture is called the client–server model, and a single overall computation is distributed across multiple processes or devices.

Servers can provide various functionalities, often called "services", such as sharing data or resources among multiple clients, or performing computation for a client.

A single server can serve multiple clients, and a single client can use multiple servers.

A client process may run on the same device or may connect over a network to a server on a different device.

Typical servers are database servers, file servers, mail servers, print servers, web servers, game servers, and application servers.

Zero-configuration networking (zeroconf) is a set of technologies that automatically creates a usable computer network based on the Internet Protocol Suite (TCP/IP) when computers or network peripherals are interconnected.

It does not require manual operator intervention or special configuration servers.

A content delivery network or content distribution network (CDN) is a globally distributed network of proxy servers deployed in multiple data centers.

The goal of a CDN is to serve content to end-users with high availability and high performance.

CDNs serve a large fraction of the Internet content today, including web objects (text, graphics and scripts), downloadable objects (media files, software, documents), applications (e-commerce, portals), live streaming media, on-demand streaming media, and social networks.
