Websites are typically dedicated to a particular topic or purpose, ranging from entertainment and social networking to providing news and education.All publicly accessible websites collectively constitute the World Wide Web, while private websites, such as a company's website for its employees, are typically a part of an intranet.Images are commonly used to effect the desired appearance and as part of the main content.
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.
Websites can have many functions and can be used in various fashions; a website can be a personal website, a commercial website for a company, a government website or a non-profit organization website.
Before the introduction of HTML and HTTP, other protocols such as File Transfer Protocol and the gopher protocol were used to retrieve individual files from a server.
These protocols offer a simple directory structure which the user navigates and chooses files to download.
Apache is the most commonly used web server software (according to Netcraft statistics) and Microsoft's IIS is also commonly used.
Some alternatives, such as Nginx, Lighttpd, Hiawatha or Cherokee, are fully functional and lightweight.
This type of website usually displays the same information to all visitors.
Similar to handing out a printed brochure to customers or clients, a static website will generally provide consistent, standard information for an extended period of time.
Web pages are accessed and transported with the Hypertext Transfer Protocol (HTTP), which may optionally employ encryption (HTTP Secure, HTTPS) to provide security and privacy for the user.
The user's application, often a web browser, renders the page content according to its HTML markup instructions onto a display terminal.
This may include information about a company and its products and services through text, photos, animations, audio/video, and navigation menus.
