The Command Prompt

What is the command prompt?

To understand what the command prompt is requires a little background information. On each occasion that a user clicks on the user interface a command is executed. This may be for something as trivial as opening an application. Clicking on some area of the screen using graphically pleasing menus or buttons, is easier for the user rather than typing lines of commands. However the option is there for the user to type commands rather than use the GUI(Graphical User Interface). This is the command prompt. There will be occasions when it may be more benefical to type the commands at the command prompt rather that use the predefined commands behind the menus or buttons.

To open the command prompt, from the start menu select start->programs->Accessories->command prompt .The procedure can be seen below.

Alternatively you can start the command prompt by selecting run from the start menu and typing cmd. The procedure is shown below.

Once you have launched the command prompt it should look like the following.

You are now free to type commands and press return to have them executed.
