A. Unary
B.
binary
C.
both a and b
D.
none
Answer: B
Explanation:
In Java the bitwise and bit shift operators are used to manipulate the contents of variables at a bit level according to binary format.
26.
The __________ operator takes a single bit and inverts the level of that bit pattern and can be applied to any of the integral types.
A. Unary complement
B.
bitwise complement
C.
unary bitwise complement ("~")
D.
all the above
Answer: C
Explanation:
The Unary bitwise complement("~ ") operator takes a single bit and inverts the level of that bit pattern and can be applied to any of the integral types.

30.
The _____________ has the registers including a fixed number of available bits for storing numerals.
A. CPU
B.
key board
C.
monitor
D.
computer processor
Answer: D
Explanation:
The computer processor has the registers including a fixed number of available bits for storing numerals. So it is possible to "shift out" some bits of the register at one end, and "shift in" from the other end.
