+# The "shell prompt" is the character at the beginning of the command line, for example "$" or "#". It indicates that the shell is ready to accept commands. Do not use "command prompt," "terminal," or "shell."
+# "Terminal emulation" refers to making a computer respond like a particular type of terminal. Terminal emulation programs allow you to access a mainframe computer or bulletin board service with a personal computer.
