Unique Resource Locators  (AKA Web Address)

An URL (aka web address) is the alpha-numerical address that humans type in to a web browser to access a website. Humans like to use URLs rather than IP Addresses because they are easy to remember.

An URL can be the name of a website or a specific page and may also contain query parameters / port numbers.

Example URLs

  • Website Address – https://www.google.com
  • Webpage Address- https://learnlearn.uk/alevelcs/
  • Webpage address with search query – https://learnlearn.uk/alevelcs/?s=internet

Internet enable devices use IP addresses to communicate instead or URLs, so each URL must be resolved to an IP address before data can be sent across the Internet.
