Example: Conversion of a Binary Number to Octal:

Let’s consider the conversion of the binary number 110110101011 to octal.

1. Group Binary Digits:
   • Group the binary digits into sets of three, starting from the right. In this case, it becomes 110 110 101 011.
2. Pad with Zeros (if necessary):
   • If the leftmost group doesn’t have three digits, pad it with zeros. In this case, the leftmost group is 011, so we pad it to become 011.
3. Convert Each Group to Octal:
   • Convert each three-digit binary group to its octal equivalent:
     • 011 in binary is 3 in octal.
     • 101 in binary is 5 in octal.
     • 110 in binary is 6 in octal.
     • 110 in binary is 6 in octal.
   Therefore, the binary number 110110101011 is equivalent to 3366 in octal.

Limited Applications in Computing, Especially in Low-Level Programming:

1. Historical Significance:
   • Octal was more commonly used in early computing systems, especially in the days when computer architectures and programming languages were designed with word sizes that were multiples of 3 (and hence octal digits aligned neatly).
2. Low-Level Programming:
   • In some low-level programming contexts, octal is still used occasionally. For example, when dealing with file permissions in Unix-like operating systems, octal representation is employed (e.g., 755 for read, write, and execute permissions for the owner, and read and execute permissions for others).
3. Bitwise Operations:
   • In certain bitwise operations and machine-level programming, octal representations might be encountered, although hexadecimal is more prevalent in such contexts.
4. Limited Usage Today:
   • With the widespread adoption of hexadecimal and binary in modern computing, the octal system’s usage has diminished. Most programming languages and systems primarily use binary and hexadecimal for bitwise operations and memory addressing.

While the octal system has historical significance, especially in the early days of computing, its use has become limited in contemporary computing, giving way to binary and hexadecimal representations in most applications.

Like other positional numeral systems, each digit’s position in a hexadecimal number represents a power of 16. Hexadecimal is commonly used in computing and programming due to its convenient representation of binary-coded values. One hexadecimal digit corresponds to exactly four binary digits (bits), making it a compact and readable format.

Example: Conversion of a Binary Number to Hexadecimal:

Let’s consider the conversion of the binary number 110110101011 to hexadecimal.

1. Group Binary Digits:
   • Group the binary digits into sets of four, starting from the right. In this case, it becomes 1101 1010 1011.
2. Pad with Zeros (if necessary):
   • If the leftmost group doesn’t have four digits, pad it with zeros. In this case, the leftmost group is 1101, so no padding is needed.
3. Convert Each Group to Hexadecimal:
   • Convert each four-digit binary group to its hexadecimal equivalent:
     • 1101 in binary is D in hexadecimal.
     • 1010 in binary is A in hexadecimal.
     • 1011 in binary is B in hexadecimal.
   Therefore, the binary number 110110101011 is equivalent to DAB in hexadecimal.
