4. [ 20 / 15 / 10 / 0 ] The Navy severely restricts the use of flash drives (USB memory sticks).
Why (complete sentences, spelling, grammar)?
5. [ 20 / 15 / 10 / 0 ] When a program is launched, what happens before the fetch-decode-execute
cycle starts?
6. [ 10 / 8 / 5 / 0 ] Look at the diagram above, and review the fetch-decode-execute cycle demo
in the course notes. You start the program Notepad.exe running and begin working on a
simple text file. Without exiting Notepad, you use frhed (the hex editor) to open the file
Notepad.exe and you change the values of many, even all of the bytes in the file
Notepad.exe and save it. No matter what changes you make, however, the running Notepad
that you have is still there: you can switch back to it and keep editing text, it works just the same
as ever. Why didn’t all those changes to Notepad.exe cause any problems to the currently
running Notepad? (Hint: if you exited Notepad and then tried to re-launch it you would have
serious problems!)
