A "pipe" is where output is redirected to another program. It exists in Windows as well as Unix (although you don't see much of it in Windows usage).
The character used in piping is the pipe character ('|').
For example, you wanted to create a MD5 hash of the message "Hello World!" you'd do echo "Hello World!" | md5sum. The echo command will output "Hello World" to standard output (also called stdout), and the pipe will redirect that to the md5sum utility, which will calculate the MD5 hash from the output as input.
