URL Format

A URL consists of three parts:

  1. Protocol — what method will be used to transfer the data (usually HTTP.)
  2. Host — the unique name of the computer (Host) that holds the resource
  3. Path — a relative path name of the disk file on the host

These parts are put together like this: 

Protocol://Host/Path

For example, here is a popular URL: 

http://chortle.ccsu.edu/default.htm

QUESTION 13:

What is the host name in the above URL?
