What is a URL?
For example, the URL
ftp://ftp.company.com/freeware/program.exe tells us that:
- the protocol used to access and transmit the resource is FTP;
- the resource is on the machine "ftp" in the second-level domain
"company", which is part of ".com," or the top level domain for
commercial organizations;
- the resource in the directory labled "freeware" and is a software program
called "program.exe" .
Not all URLs will have the directory and filename.
