Example 1

Column A indicates that the address is a website address. The www is not alway's present, as it merely points the browser to a particular server for the pages. By default, www is used. (www stands for World Wide Web)

Column B is the name of the company of who's website you want to visit.

Column D is called a Top Level Domain (TLD). This is country specific, and in this example means a UK domain.

Column C is determined be the country the TLD represents, in this case the UK. They have determined that .co will represent a company.

So, as .co.uk domain will indicate a UK company. Generally only UK companies will have a .co.uk domain.

Example 2

Column A represents the type of website protocol currently in use. Http means Hyper Text Transmission Protocol. This is used by default in all browsers, so is not alway's necessary to type it in with the address as the browser will add it in automatically.

Column D in this address is what is called a generic Top Level Domain (gTLD), which is not country specific. So a .com address could be an American company, a UK company or any other company in the world.

Column B, as with Column A in Example 1, indicates that the address is a website address. The www is not alway's present, as it merely points the browser to a particular Server for the pages. By default, www is used.
