The Command Line Interface

With a command line interface the user interacts with the computer by typing commands.

An interaction with a computer using a command line interface usually follows these two steps :

• The user types a command e.g. "dir".
• The computer carries out the command and displays its results.

Examples of systems which use a command line interface are :

1. MS-DOS
2. BBC Micro
3. Quest database

Advantages	Disadvantages
An experienced user who knows a package well can enter commands quicker than he could select options using lots of menus. Can be used on a computer which has very little memory and is slow.	It is very difficult to remember all the possible commands and exactly how they should be typed. Error messages are not usually very helpful.
