The set of visual basic instructions that tells an object how to behave after an action by the user (such as clicking a button) is referred to as a(n)

Event procedure

Explanation:

Whenever a user perform certain action, such as press a button on the keyboard or click the mouse, etc. such action are called an event. when an event occurs, Visual Basic looks for BASIC instructions to tell the object in the program how to behave to the user event. The Visual Basic instructions that responds to this specific event is called an event procedure.

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.
