WebsitesA website is a collection of related web

pages containing images, videos or other digital assets. A website is hosted on at least one web server, accessible via a network such as the Internet or a private local area network through an Internet address known as a Uniform Resource Locator. All publicly accessible websites collectively constitute the World Wide Web.

Websites are written in, or dynamically converted to, HTML (Hyper Text Markup Language) and are accessed using a software interface classified as a user agent. Web pages can be viewed or otherwise accessed from a range of computer-based and Internet-enabled devices of various sizes, including desktop computers, laptops, PDAs and cell phones.

A web page is a document, typically written in plain text with formatting instructions of Hypertext Markup Language (HTML, XHTML). A web page may incorporate elements from other websites.

Web pages are accessed and transported with the Hypertext Transfer Protocol (HTTP).

The pages of a website can usually be accessed from a simple Uniform Resource Locator (URL) called the homepage.

Some websites require a subscription to access some or all of their content. Examples of subscription websites include many business sites, parts of news websites, academic journal websites, gaming websites, file-sharing websites, message boards, web-based email, social networking websites…

Legal: Copyright Copyright : The Internet has been characterized as

the largest threat to copyright since its inception. The Internet is awash in information, much of it with varying degrees of copyright protection. Copyrighted works on the net include news stories, software, novels, screenplays, graphics, pictures, Usenet messages and even email. In fact, the frightening reality is that almost everything on the Net is protected by copyright law.

WAPWireless Application Protocol (WAP) is

a technical standard for accessing information over a mobile wireless network. A WAP browser is a web browser for mobile devices such as mobile phones that uses the protocol.

Mobile BrowserA mobile browser, also called

a microbrowser, minibrowser, or wireless internet browser (WIB), is a web browser designed for use on a mobile device such as a mobile phone or PDA. Mobile browsers are optimized so as to display Web content most effectively for small screens on portable devices. Mobile browser software must be small and efficient to accommodate the low memory capacity and low-bandwidth of wireless handheld devices.

Example: Opera mini.
