2. What is the World Wide Web? The World Wide Web is an application that utilises the Internet to provide a ubiquitous and user-friendly interface on which to share and retrieve information (Pallen, 1995). Accessed via software called web browsers, the Web is a database of documents, all linked together to form a limitless ‘web’ of information (Woods, 2013c). These documents are a combination of hypertext and hypermedia, meaning that they contain both text and other media such as audio, images or video, which are able to be linked to other documents or ‘webpages’ (Ingram, 1995).
With hypertext, a word or phrase can contain a link to another Web site. 3 What is a computer network?

Prior to the introduction of the domain name system, computers use hosts files to map human readable names to ip addresses. A sub-net mask is used to separate the host address portion of an IP address from the network address. The sub-net mask within the TCP/IP configuration is used to distinguish the network address from the host address. In dotted-decimal notation, each Ipv4 address is broken into four octets. Server computers and other systems that need to be accessed reliably by network clients should be configured with a static IP address.
