Bit

B.

Byte

C.

Word

D.

Nibble

Answer: Option C

Explanation:

It can be represented up to 16 different values with the help of a Word. Nibble is a combination of four bits and Byte is a combination of 8 bits. It is “word” which is said to be a collection of 16-bits on most of the systems.

If the decimal number is a fraction then its binary equivalent is obtained by the number continuously by 2?

A.

Dividing

B.

Multiplying

C.

Adding

D.

Subtracting

Answer: Option B

Explanation:

On multiplying the decimal number continuously by 2, the binary equivalent is obtained by the collection of the integer part. However, if it’s an integer, then it’s binary equivalent is determined by dividing the number by 2 and collecting the remainders.

The representation of octal number (532.2)8 in decimal is?

A.

(346.25)10

B.

(532.864)10

C.

(340.67)10

D.

(531.668)10

Answer: Option A

Explanation:

Octal to Decimal conversion is obtained by multiplying 8 to the power of base index along with the value at that index position. (532.2)8 = 5 * 8^{2} + 3 * 8^{1} + 2 * 8^{0} + 2 * 8^{-1} = (346.25)10

The decimal equivalent of the binary number (1011.011)2 is?

A.

(11.375)10

B.

(10.123)10

C.

(11.175)10

D.

(9.23)10

Answer: Option A

Explanation:

Binary to Decimal conversion is obtained by multiplying 2 to the power of base index along with the value at that index position. 1 * 2^{3} + 0 * 2^{2} + 1 * 2^{1} +1*2^{0} + 0 * 2^{-1} +1 * 2^{-2} + 1 * 2^{-3} = (11.375)10 Hence, (1011.011)2 = (11.375)10
