Basic Terminology


URL is an abbreviation for Uniform Resource Locator.

Sometimes also referred to as URI (Uniform Resource Identifier)


URL is a protocol that helps in specifying address of any resource that resides on web (like website, blog, audio files, video files, etc.) and can be accessed via internet. It is also known as web address.

Generally, URL comprises of:

  • a protocol,
  • hostname

http – protocol
