The |ALU |component |of |the |CPU |moves |data |and |instructions |between |main |memory |and
registers.
|
True |or |false
Ans: | F
A |complex |chain |of |events |occurs |when |the |CPU |executes |a |program.
True |or |False
Ans: | T
The |CPU |alternates |constantly |between |fetch |and |execution |cycles.
True |or |False
Ans: | T
The |operand |of |a |CPU |instruction |cannot |contain |the |location |of |a |data |item.
,True |or |False
Ans: | F
Data |inputs |are |accessed |from |storage |or |extracted |directly |from |the |operands |and |stored |in |one
or |more |registers.
|
True |or |False
Ans: | T
The |control |unit |cannot |execute |instructions |without |assistance |from |the |ALU.
True |or |False
Ans: | F
MOVE |tests |the |bit |values |in |the |source |location |and |moves |these |values |to |the |destination
location.
|
True |or |False
Ans: | F
,With |bit |strings, |NOT |treats |each |bit |in |the |bit |string |as |a |separate |Boolean |value.
True |or |False
Ans: | T
Binary |addition |works |with |complex |data |types, |such |as |floating-point |and |double-precision
numbers.
|
True |or |False
Ans: | F
Shifting |an |8-bit |twos |complement |value |to |the |right |by |seven |positions |is |a |simple |way |to |extract
and |test |the |sign |bit.
|
True |or |False
Ans: | T
Arithmetic |SHIFT |instructions |are |more |complex |when |applied |to |twos |complement |values
because |the |rightmost |bit |is |a |sign |bit.
|
, True |or |False
Ans: | F
The |BRANCH |command |has |one |operand |containing |the |memory |address |of |the |next
instruction.
|
True |or |False
Ans: | T
An |8-bit |op |code |provides |256 |possible |instructions |numbered |0 |through |255.
True |or |False
Ans: | T
A |large |set |of |complex |instructions |often |goes |hand |in |hand |with |fixed-length |instruction
formats.
