• Web pages that conform to standards can be viewed as developer intended on compliant browsers and devices

• Web pages distributed and accessed using Hypertext Transfer Protocol (HTTP)

• Pages stored on networked computers running server software to respond to client requests

WWW

Computers hosting Web sites function as Web servers

Transmission of requested Web pages can use encryption in the form of Hypertext Transfer Protocol Secure (HTTPS)
