### Multiple Choice Questions On Computer Arithmetic - Set 1

Following are the multiple choice questions on Computer Arithmetic based on the UGC-NET syllabus. Computer Arithmetic multiple choice questions.

1) A shift register can be used for ?
1. Serial to parallel conversion
2. Parallel to serial conversion
3. Digital delay line
4. All of the above
5. None of the above
Explanation:Shift registers can have both parallel and serial inputs. These are often configured as serial - in - parallel- out or parallel - in - serial - out.

2)  Semiconductor memory is-
1. Somewhat large than the magnetic core memory
2. A non-volatile memory
3. Somewhat slower than magnetic core memory
4. All of above
5. None of these
Explanation: Semiconductor memory is an electronic storage device often used as computer memory. Examples of semiconductor memory is: ROM, flash memory,  magnetoresistive random-access memory (MRAM)
3) Which of the following is a universal gate  ?
1. AND
2. EX-OR
3. OR
4. NAND
Explanation: NAND is the universal gate as using this gate we can have all other gates like AND, OR, EX-OR, NOT.
4) The logic 1 in positive logic system is represented by ?
1. Zero voltage
2. Lower voltage level
3. Higher voltage level
4. Negative voltage
5. None of the above
Explanation:The logic 1 is represented by higher voltage while 0 is represented as low voltage.
5) Which function -positive logic is equivalent to OR function in negative logic?
1. NOT
2. OR
3. AND
4. NOR
5. None of the above
Explanation: AND function performs performs as OR in negative logic.

6) Which of the following logic expressions is wrong ?
1. 1+0=1
2. 1+1=0
3. 1+0+1=1
4.  1+1+1=1
5. None of the above
Explanation: 1+0 = 1 again this result is added to 1 as 1+1 which is equal to 0 with carry 1 but not equal to 1.
7)  A Combination logic circuit that is used when it is desired to send data from two or more source through a single transmission line is known as-
1. Decoder
2. Encoder
3. Multiplexer
4. De multiplexer
5. None of the above
Explanation:Multiplexer is a device that selects one of the analog or digital input and send it through single transmission line.

8)  The m-bit parallel adder consists of-
1. (m+1) full adders
2. m/2 full adders
3. m-1 full adders
4. m full adders
5. None of the above
Explanation:No explanation

9)  A logic circuit which is used to change a BCD number into an equivalent decimal number is-

1. Decoder
2. Encoder
3. Multiplexer
4. Code converter
5. None of the above
Explanation:Decoder is used to convert the BCD numbers into decimal.

10) Which of the following property is true in context of Well Formed Formula(WFF)  ?

1. Each letter is a term
2. If x and y are terms then x = y is a formula
3. If P is a formula then 7p is a formula
4. All of above
Explanation:No explanation for this question.
