Your friend called and told you that he saw information about the classified XYZ program on the Internet. As a cleared employee who does not work on the XYZ program, is it okay for you to view that information on the Internet since it's already in the public domain?

The answer is "Yes, you can access the information because you're a certified employee".

Explanation:

The term "public domain" relates to content that isn't covered by copyright, trademarks, or patents. In other words, it relates to artistic material.  Its public, not for the single writer or artist, which can hold these works.  

In this, everyone is authorized for using public domain work but no one is ever allowed to use it, but only the certified employee can use it, that's why you can access the details because you're certified.

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.
