Each sentences below consist of a word or a phrase which is bold. It is followed by four words or phrases. Select the word or pharse which is closes to the OPPOSITE in meaning of the bold word or phrase.

Q1: The leader was pragmatic in his approach to the problem facing the country.

A vague

B optimistic

C idealistic

D indefinite

Q2:
What will be the output of the program? 
#include<stdio.h>
#define JOIN(s1, s2) printf("%s=%s %s=%s \n", #s1, s1, #s2, s2);
int main()
{
    char *str1="India";
    char *str2="Aptitude";
    JOIN(str1, str2);
    return 0;
}

A str1=India str2=AptitudeCrack

B Error: in macro substitution

C str1=India str2=Aptitude

D str1=AptitudeCrack str2=Aptitude

Q3: Identify the type of gate below from the equation 

A NAND gate

B Ex-NOR gate

C OR gate

D Ex-OR gate

Q4: How is odd parity generated differently from even parity?

A The last output is inverted.

B The first output is inverted.

Q5: Parity systems are defined as either________ or ________ and will add an extra ________ to the digital information being transmitted.

A odd, even, bit

B on, off, decimal

C upper, lower, digit

D positive, negative, byte

Q6: Which type of gate can be used to add two bits?

A Ex-NAND

B NOR

C Ex-NOR

D Ex-OR

Q7: Why is an exclusive-NOR gate also called an equality gate?

A The output is true if the inputs are equal.

B The output is false if the inputs are equal.

C The output is true if the inputs are opposite.

Q8: Show from the truth table how an exclusive-OR gate can be used to invert the data on one input if the other input is a special control function.

A Using A as the control, when A = 0, X is the same as B. When A = 1, X is the same as B.

B Using A as the control, when A = 0, X is the same as B. When A = 1, X is the inverse of B.

C Using A as the control, when A = 0, X is the inverse of B. When A = 1, X is the inverse of B.

D Using A as the control, when A = 0, X is the inverse of B. When A = 1, X is the same as B.

Q9:
Determine odd parity for each of the following data words:
1011101        11110111        1001101

A P = 1, P = 1, P = 1

B P = 0, P = 0, P = 1

C P = 1, P = 1, P = 0

D P = 0, P = 0, P = 0

Q10: The Ex-NOR is sometimes called the ________.

A inverted OR

B equality gate

C parity gate

D parity gate or the equality gate
