  3. A memory leak • never happens on modern computers • allows a program to ask for more memory if needed • happens when a program is assigned memory space which is never given back to the operating system • can cause a computer to hang up or crash • C and D

  4. The first GUI • was created by Microsoft • was created by Xerox PARC • is still in the research stage • became commercially successful with Macintoshes • B and D
