• Remote Login Accommodates Multiple Types of
  Computers
• A remote login service allows a user at one site
  to interact with application programs that run on
  a computer at another site. The power of remote
  login arises because it allows remote access to
  application programs without requiring any
  changes to the programs themselves.
• Unexpected Results From Remote Access
• Users must remember that although a remote access
  service uses the display, keyboard, and mouse on
  the user's local computer, the application can
  only interact with the files and printers on the
  remote computer.
