# 【升學考試】 急 20點 高手幫忙 20題計概是非題

1( ). The Program Counter and the Instruction Register are two names for the same place.

2( ). The A register and the accumulator are two names for the same place.

3( ). The Instruction Register is three bytes long.

4( ). The Program Counter is three bytes long.

5( ). The status hits are each one byte long.

6( ). The instruction specifier is two bytes long.

7( ). If the data to be loaded into the accumulator is stored in the operand, the instruction specifier is 00.

8( ). If the data in the accumulator is to be stored in the place named in the operand, the instruction specifier is 00.

9( ). All Pep/7 instructions occupy three bytes.

10( ). The branching instructions test the status bits.

11( ). The output of an OR gate when one input is 0 and one input is 1 is 0.

12( ). The output value of an XOR gate is 0 unless both inputs are 1.

13( ). The NOR gate produces the opposite results of the XOR gate.

14( ). A gate can be designed to accept more than two inputs.

15( ). A transistor is made of semiconductor material.

16( ). Inverting the output of an AND gate is equivalent to inverting the individual signals first, then passing them through an OR gate.

17( ). The sum of two binary digits (ignoring the carry) is expressed by an AND gate.

18( ). A full adder takes the carry-in value into account.

19( ). A multiplexer adds all of the bits on its input lines to produce its output.

20( ). Integrated circuits are classified by the number of gates contained in them.
