Definition of a URL
What is the definition of a URL?
A URL is a Uniform Resource Locator which is more commonly referred to as a domain name. By most accounts it is an addressing system used on the Internet to define a specific location. The URL can also be classified as an URI (Uniform Resource Identifier), which is a set of characters used to identify a physical IP (Internet Protocol) address on the Internet. We use URLs everyday when navigating the Internet whether we know it or not. In fact, you are at our URL while you are reading this material. The reason URLs are important is the fact that they allow you to easily identify and remember an address on World Wide Web. It would be difficult to remember an IP address like an example: 188.8.131.52 every time you wanted to check your bank statement or login to your email account and that is one of the reasons that the URL was created.
Importance of URL Definition.
The most important feature of the URL is that it allows you to change IP addresses while maintaining the same name. A personal site or even large corporation can relocate their website hosting to another physical location without having to notify every customer of the change. The change of the IP Address is transparent to visitors of the site and usually occurs over a period of 24 to 48 hours.
An important feature of the URL is that each one is unique, thus preserving the integrity of the Internet. If anyone could call their own IP Address whatever URL (or domain name) they wanted then no one would be very much trust into the sites they were interacting with. A hacker could thus call his own address Microsoft.com or Cisco.com and steal important personal information as well as credit card data.
A URL also allows large corporations with numerous IP addresses and servers to direct all traffic too one canonical name. For example, a company like MySpace.com has dozens of IP Addresses which are all bound too the URL name MySpace.com and thus enables them to balance load their website traffic too different servers. They would not be able to balance the traffic very easily if they did not have the URL.
