23
Q

What component’s primary duty is synchronizing processes inside a computer?
- Memory Bus
- System Clock
- Instruction Register
- I/O Bus

A

System Clock

24
Q

What unit on a CPU chip is responsible for computing basic addition and subtraction operations?
- ALU
- I/O
- Control Unit
- FPU

25
Match the Instruction Execution steps to the correct order and description. - Step 1 - Step 2 Step 3 Step 4 Step 5 Step 6
- The control unit fetches the next instruction from the instruction queue - The control unit increments the instruction pointer (IP, also known as the instruction counter) - The control unit decodes the instructions function to determine what the instruction will do - if the instruction uses an input operand located in memory, the control unit uses an input operation to retrieve the operand and copy it into internal registers - The ALU executes the instruction using the named registers and internal registers as operands - if the output operand is in memory, the control unit uses a write operation to store the data
26
If you wanted to find out whether an 8-bit integer contained an even number of 1 bits, which status flag would be useful - carry - parity - sign - overflow
parity
27
In the IA-32 architecture, which of the following are valid 16-bit register references ESI AH CX SS BL SP
CX SS SP
28
In the IA-32 architecture, which of the following are valid 8-bit register references AX EL SH EAX DH AL
DH AL
29
Changes made to the AL register will not modify the contents of the EAX register
False
30
Match the datatype to its use/description BYTE WORD SWORD DWORD SDWORD REAL4 REAL8
BYTE - 8-bit unsigned integer WORD - 16-bit unsigned integer SWORD - 16-bit signed integer DWORD - 32-bit unsigned integer SDWORD - 32-bit signed integer REAL4 - 32-bit (4-byte) IEEE short real REAL8 - 64-bit (8-byte) IEEE long real
