URI Stands for “Uniform Resource Identifier.” A URI identifies the name and location of a file or resource in a uniform format.

URIs provide a standard way for resources to be accessed by other computers across a network or over the World Wide Web. They are used by software programs such as Web browsers and P2P file-sharing programs to locate and download files.
