1 WEBSITES A website is a collection of web pages, images, videos or other digital assets that is hosted on one or more web servers, usually accessible via the Internet. A web page is a document, typically written in (X)HTML, that is almost always accessible via HTTP, a protocol that transfers information from the web server to display in the user's web browser. All publicly accessible websites are seen collectively as constituting the "World Wide Web".

2 WEBSITES The pages of a website can usually be accessed from a common root URL called the homepage, and usually reside on the same physical server. The URLs of the pages organize them into a hierarchy, although the hyperlinks between them control how the reader perceives the overall structure and how the traffic flows between the different parts of the site.

3 WEBSITES Some websites require a subscription to access some or all of their content. Examples of subscription sites include many business sites, parts of many news sites, academic journal sites, gaming sites, message boards, Web- based e-mail, services, social networking websites, and sites providing real-time stock market data. Because they require authentication to view the content they are technically an Intranet site.

These protocols offer a simple directory structure which the user navigates and chooses files to download.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
