Terminal

A terminal is a point used to direct users to another point. In other word, major junction on a transportation or communication line. I used to watch the story Terminal and quite fond of it. So what is Terminal on Linux?

As I previously described, terminal is one way users transport or communicate with the system. In which our point of communication with the computer system. Of course when communicating we use a language the computer understand, with commands. Compare to Windows, Linux uses UNIX as their language of communicating, while windows uses DOS. So what's the different? The way they communicate I presume. Like you speak in a dead language that people don't know. 

Command is something you tell people to do. We use a command to tell to do something. Then the command is send to to the computer system using the terminal. What command? The UNIX language command. Below are some commands in Linux for directory and files usage.
