What is the meaning of WWW1

WWW prefix (short for World Wide Web) that precedes URL addresses is an indication that the Web

address exists on the vast network of the World Wide Web. Sometimes in

"WWW2." The number that follows the "WWW" indicates that the data

being retrieved by the Web browser is gathering the information from a

different Web Server than the one that serves the typical "WWW" address.
