Question 3

What is the four drawback of using a Command Line Interface?

Answer 3

A less intuitive interface than GUI as commands are specific to each system where as there are common structures and conventions used in GUI (e.g. a house icon for ‘home’).

Users will have to learn specific commands, if they have limited experience with IT this may prove difficult to use.

The language of the commands may be a barrier. For instance the system command may be in English which may not be the user’s first language.

Limited in adaptability for users with additional needs.

Question 4

What is the four benefit of using a Command Line Interface?

Answer 4

Lower resources required so suitable for older equipment PU may not have high processing speeds or advanced GPUs.

Server and client will require less bandwidth to communicate so this makes it suitable for poorer internet connections.

Usually accessed using a ‘terminal’ window so likely to reduce potential problems with compatibility.

Only requires keyboard to interact/does not need additional peripheral such as mouse.
