CMD Basics

• CLI (command line interface): is human-computer interface that provides a way of giving orders to the computer by typing specific commands in a terminal.
• GUI (graphical user interface): A user friendly human-computer interface that allows the user to use the computer with images rather than with text commands.

-CLI vs GUI
Both allow user to give orders to the computer.
CLI requires a mouse while CLI only a keyboard.
In GUI you use images to control things while in CLI there is only plain text.
GUI operates through windows.
GUI uses more resources than CLI.

Usually there are two acceptance tests, one before software goes live (pre-live) wich is performed in a controlled enviroment to prevent failures when it goes live and the other test (post live)  inmediatly after it is launched in order to correct new failures detected.
