A web server is computer software and underlying hardware that accepts requests via HTTP (the network protocol created to distribute web content) or its secure variant HTTPS.

- Web server

Web browsers receive HTML documents from a web server or from local storage and render the documents into multimedia web pages.

- HTML

A web browser, for example, may be the client whereas a process, named web server, running on a computer hosting one or more websites may be the server.

- Hypertext Transfer Protocol

The server, which provides resources such as HTML files and other content or performs other functions on behalf of the client, returns a response message to the client.

These capabilities, along with the multimedia features of NCSA's Mosaic browser (also able to manage HTML FORMs in order to send data to web server) highlighted the potential of web technology for publishing and distributed computing applications.

Crawlers can validate hyperlinks and HTML code.

As the crawler visits these URLs, by communicating with web servers that respond to those URLs, it identifies all the hyperlinks in the retrieved web pages and adds them to the list of URLs to visit, called the crawl frontier.

Endless combinations of HTTP GET (URL-based) parameters exist, of which only a small selection will actually return unique content.

When a user requests a web page from a particular website, the web browser retrieves the necessary content from a web server and then displays the page on the user's device.

In Hypertext Transfer Protocol technical texts, web browsers (and other clients) are commonly referred to as user agents.

Since the early 2000s, browsers have greatly expanded their HTML, CSS, JavaScript, and multimedia capabilities.
