Each digit in a binary number represents a specific power of 2, starting from the rightmost digit, which represents 2^0 (1). The next digit to the left represents 2^1 (2), then 2^2 (4), and so on.
For example, the binary number 1010 represents the sum of 2^3 (8) and 2^1 (2), resulting in the decimal value of 10.
Explanation of binary digit (bit)
In binary, each digit is called a “bit,” which is a contraction of “binary digit.” A bit can have one of two states: 0 or 1. Each bit represents a discrete piece of information in a binary number.
Bits are the foundation of digital information storage and manipulation. They can represent the presence or absence of an electrical signal, which is the basis of binary logic operations that computers perform.
Understanding the concept of bits is essential because it forms the basis for converting between hexadecimal and binary. Each hexadecimal digit corresponds to a unique combination of bits, which enables the conversion process.
In summary, the binary number system is a fundamental system in digital electronics and computer science. It uses only two digits, 0 and 1, to represent numbers.

Calculating the Number of Bits in Hexadecimal
Explanation of the relationship between hexadecimal and binary bits
In computer science and digital systems, binary is the fundamental language used to represent and process data. Each binary digit, commonly referred to as a “bit,” can have a value of eTher 0 or 1. However, hexadecimal is another number system commonly used in computer science and programming. Hexadecimal has a base of 16, which means it uses 16 unique symbols to represent values ranging from 0 to 15. The symbols used in hexadecimal are the numerals 0-9 and the letters A-F, where A represents 10, B represents 11, and so on up to F, which represents 15.
The relationship between hexadecimal and binary lies in the fact that both systems are based on powers of 2. Specifically, one hexadecimal digit can be equated to four binary digits. This is because each hexadecimal digit can represent values from 0 to 15, which can be expressed using four binary digits (0000 to 1111).
Formula for calculating the number of bits in a hexadecimal number
To calculate the number of bits in a hexadecimal number, the formula is as follows:
Number of bits = (number of hexadecimal digits) * 4
This formula works because each hexadecimal digit represents four binary digits. By multiplying the number of hexadecimal digits by 4, we can determine the equivalent number of bits.
For example, if we have a hexadecimal number with 6 digits, the calculation would be:
Number of bits = 6 * 4 = 24
Therefore, the hexadecimal number with 6 digits would have 24 bits.
It is important to note that this formula assumes that each hexadecimal digit is an exact representation of four binary digits. In some cases, leading zeros may be omitted when representing a hexadecimal number in binary. For example, the hexadecimal digit “A” would be equivalent to “1010” in binary, but if four bits are allotted, it may be represented as “A = 1010” instead of “A = 00001010”. This can affect the calculation of the number of bits, so it is essential to consider such scenarios when converting between hexadecimal and binary.
