Line feed and carriage return
In the Networking module, we introduce ASCII and Unicode. If you are unfamiliar with ASCII, do some background reading now.
In any Windows system, if I look at the hidden characters in a file, I can see the carriage return [CR] and line feed [LF] characters.

In a Linux system, I opened a script file and noted the differences and then used WinSCP to copy it to my Windows workstation. Only [LF] characters at the end of each line!

Windows and Linux treat text files a bit differently, keep this in mind if you are moving files from system to system.
