For example, a printer (shown to the right) is an external device because it is connected to the back of the computer and is outside of the case. However, a video card is an internal device since it is found inside of the computer case.

3. With software an external file is anything outside of the file currently loaded. For example, an external CSS or JavaScript file is a file that can be loaded from the HTML page being viewed.

4. With an operating system, external refers to any command that is not part of the shell. See the external command definition when referring to a command.

5. When referring to a network, external can be used to describe data that is accessible to those inside and outside of the private network. For example, the Internet is an external source of data on a network.
