What does 'enter' mean in computing terms?

Answer 1

A key that moves the cursor (or insertion point) to the beginning of the next line, or returns control to whatever program is currently running. After a program requests information from you (by displaying a prompt), it will usually not respond to your input until you have pressed the Enter or Return key. This allows you to correct typing mistakes or to reconsider your entry before it is too late. In many applications, pressing the Enter key moves the cursor to the next field. In graphical user interfaces, pressing Enter activates the currently selected button or option. On most keyboards, it is the large key to the right of the alphabet keys. It is used to create a line break or submit text on a form. The word Enter comes from French / Latin, to go in.
