The Internet
The Internet is a WAN (Wide Area Network) that connects millions of LANs worldwide. It connects computers using fibre-optic or copper cables and wireless networks. It is used for communication and the transmission of data. It is hardware.
The World Wide Web is just one of the many facilities that make use of the internet. It is software written government by W3C (World Wide Web Consortium). It is dependant on the internet and is used to share files, documents and webpages. Webpages are written in HTML which is the de jure standard for the World Wide Web.
HTML (Hyper Text Mark-up Language) is not a programming language. It is a markup language that tells a browser how to interpret and display data on a webpage through the use of predefined tags. It is a de jure protocol that most browsers accept. HTML also allows for hyperlinks which link to other webpages or documents. Here is an example of HTML code: < h1 >Heading< /h1 > < h1 > is the open tag for the header. This makes the text larger. < /h1 > ends the tag so it doesn’t effect all text after this.
To make sites more aesthetically pleasing CSS (Cascading Style Sheets) is used. These are files that HTML can reference to apply styles, sizes fonts, colours, etc. to elements on a web page. CSS can also be used to format web pages differently for different platforms such as phones, tablets and PCs. Javascript and Flash can also be used to make the sites more interactive and graphical.
