Question 6 • Introduction to Information Technology - EL3701

What process is used to convert numbers between the binary system and the decimal system?

Answer

A

Enter the number in a calculator, divide by 2, and multiply by 10.

B

Convert each binary number to a letter, then use the letter’s place in the alphabet as the decimal representation ( e.g., A = 1, B = 2).

C

Add up the digits in the binary number and place the sum behind a decimal point.

D

Look up the number on a binary-to-decimal conversion table.

Explanation

A binary number can be converted to decimal by matching it with its equivalent on a binary-to-decimal conversion table. The other choices do not correctly account for the place values used in binary numbers, which are powers of 2.
