Kareem made some changes to his powerpoint presentation? he wants to keep the changes and not change the name of the file. which command should he use?

Since Kareem only wanted to save the changes that he has done to his PowerPoint file without changing the name of his file, he can use the ‘Save’ command. The easiest way to do this, and is available in all version of Microsoft PowerPoint, is through the Ctrl + S shortcut. If Kareem is using a Windows OS computer. However, if Kareem is instead using a Mac computer, he can choose to use the Command + S to save his PowerPoint file.

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.
