Binary | MCQs

Explanation

Solution

• 13 ÷ 2 = 6, remainder 1

• 6 ÷ 2 = 3, remainder 0

• 3 ÷ 2 = 1, remainder 1

• 1 ÷ 2 = 0, remainder 1

Reading the remainders from bottom to top: 1101

So, 13 in binary = 1101.

Explanation

Binary coded numbers are in the form of a series of 0s and 1s, also known as bits. 

A number represented in the base-2 numeral system.

It uses only the digits 0 and 1.

For example, (101)2 is a binary number.

Explanation

A typical 32-bit computer usually uses the binary number system.

A binary number is a number that is stated using the base-2 numeral system or binary numeral system, which normally utilizes just two symbols: 0 (zero) and 1 (one).

It is a sort of CPU architecture with the ability to send and receive 32 bits of data.

Explanation

A bit is the smallest unit of data in a computer.

A bit has a single binary value, either 0 or 1.

Explanation

A nibble can have 16 possible values due to the four bits that are the same as one hexadecimal.

In computer architecture, 8-bit integers or other data units are those that are 8 bits 

Unit of: digital information, data size

Unit system: unit derived from bit

Explanation

Note that the BCD code is 12 bits long since each of the decimal digits is coded by four bits.

Explanation

Machine language, also known as binary

It is the most fundamental level of information stored in a computer system and uses only the values 0 and 1. 

Explanation

All data entered into a computer is converted into binary numbers (0s and 1s) for processing and storage.

Computers operate using the binary number system internally.

Explanation

A computer processes and stores all data in digital form, i.e., binary (0s and 1s).

Even analog data is converted into digital signals before processing.

Explanation

To find the decimal equivalent of the binary number 1011:

(1 × 2³) + (0 × 2²) + (1 × 2¹) + (1 × 2⁰)

= (1 × 8) + (0 × 4) + (1 × 2) + (1 × 1)

= 8 + 0 + 2 + 1

= 11
