A domain is a person or organization's unique space on the internet. It is commonly used to mean the name of your website.
Domain Name
A name that identifies one or more IP addresses. Domain names are used in URLs to identify particular Web pages. For example, in the URL http://www.pcwebopedia.com/index.html, the domain name is pcwebopedia.com.
Host / Hosting
In order for you to have a website, a computer somewhere, with all the necessary software, has to provide you with 3 things: an IP (domain) address, physical space to store the information and bandwidth that accommodates the flow of information that is taking place on your behalf. The company that provides you with these facilities is your host and you will pay them a fee for hosting your site and or email address.
HTML/Hyper Text Markup Language
This is the base language that is used for creating websites.
HTTP Hyper Text Transfer Protocol
This is a method used to transfer information on the internet and normally precedes the "description" of the actual resource being accessed and transferred.
JPG
A type of file used for images, especially photographs. Images used on web pages work best as jpg or gif.
Server
A server is a computer that is used to house websites and provide a physical storage area for websites and emails. Without a server, your website would not be viewable to the world. Servers are normally provided by hosting companies who keep the servers in special premises, under special conditions and with permanent connections to the internet.
Upload
For a website to be visible to the world, it has to be put on the server that is hosting it. This process is called uploading because you are literally loading your information, pages, pictures, etc. up onto the server.

Just one page rather than a complete website (see below). A page is not the same as, for example, the page in a book. The length is not limited by a fixed height and width, but by user-friendliness, good practice and practicality.
Website Adress
This is the location of your website and is normally typed as www.the-name-of-the website.co.za
