Event-driven GUI programs sometimes require fewer coded loops than their counterpart console applications because some events are determined by the when the program is running.

User-action

Explanation:

In some cases, an event can be as a result of a user action, such as when the user clicks the mouse button, types a character, or clicks a button.

The program might respond to a mouse-click on a canvas by drawing a shape, to a typed character by adding the character to an input box, or to a click on a button by clearing a drawing.

answer: internal fragmentation is the difference between the (fixed) size of a memory hole and the data within in that memory. for example, if a 1,024 byte block of memory holds 800 bytes of data, then the 224 bytes difference is considered lost to internal fragmentation.

external fragmentation occurs when the sum of memory fragments is large enough to satisfy a request, but the holes are non-contiguous and the request cannot be satisfied. this can occur when memory is dynamically allocated and freed.
