Answer the following statements true (T) or false (F)

1. On a segmented system, the dynamically expanded address consists of two parts: a segment number and a displacement. 2. With segmentation and paging, addresses are divided into a segment number and a displacement, but the segments are paged into memory. 3. If a program attempts to modify (or, sometimes, even to read) the contents of memory locations that do not belong to it, the operating system’s memory protection routine intervenes and (usually) terminates the program. 4. Loading only currently active pages is the underlying principle behind modern overlay systems. 5. The external paging device is usually RAM.
