  2. Using CLI is faster than GUI. In GUI a person relies heavily on using a mouse to perform operations. In CLI an operator relies on typing commands in order to perform specific functions. Commonly used sequence of commands can be automated by specifying these commands in script files.
  3. Bandwidth requirements to transfer text only data is much less than transfer graphical data.
  4. Encrypting text only data is much easier than encrypting graphical data, due to lower volume of transferred data.
