Term 8 of 205
In an actual computer system with a full-scale operating system, what would the exit service do?
Return control to the operating system.
Halt the processor.
Halt the operating system.
Immediately start running another user program.
, Term 9 of 205

the Bare Machine option turned ON?
0x00000000
0x00400000
0x10000000
0xFFFFFFFF
Term 10 of 205
What are the three steps in the machine cycle?
A. the character is in the low-order byte. the three high-order bytes are zero.
A. fetch, increment, execute
B. several sequential instructions are simultaneously prepared for execution while one
instruction finishes its execution.
A. no.
Term 11 of 205
How is an array of integers typically implemented?
The integers of the array are put in sequential words of memory. A word of zeros follows
the last integer.
The integers of the array are put in sequential words of memory. Another word of memory
contains the length of the array.
The integers of the array are put in sequential bytes of memory. The last byte holds the
length of the array.
Each integer of the array is assigned to one of the general purpose registers.
