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

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

First, the octal number is converted to it’s equivalent binary form, by writing the binary equivalent of each digit in form of 3 bits. Then, the binary equivalent bits are grouped in terms of 4 bits and then for each of the 4-bits, the respective digit is written. Thus, the hexadecimal equivalent is obtained. (651.124)8 = (110 101 001.001 010 100)2 = (110101001.001010100)2 = (0001 1010 1001.0010 1010)2 = (1A9.2A)16

The octal equivalent of the decimal number (417)10 is:

A.

(641)8

B.

(619)8

C.

(640)8

D.

(598)8

Answer: Option A

Explanation:

Octal equivalent of decimal number is obtained by dividing the number by 8 and collecting the remainders in reverse order. 8 | 417 8 | 52 — 1 8 | 6 – 4 So, (417)10= (641)8
