Base 36 (alphanumeric without case) "0123456789 ABCDEFGHIJKL MNOPQRSTUVWXYZ".

Number Systems

• Base 2 Number System 
  Bin (binary system) 

  Also known as binary number system. There are only 2 binary digits: 0 and 1.
  This represents on and off state which is the only language a computer understands because it's the easiest way to switch instructions through electrical signals..
  Binary is base 2, and it's made up of only 0’s and 1’s.
  0 1
  A Byte [01001010] is the equivalence of 8bits

• Base 8 Number System
  oct (octal systems),
  Octal means 8.  Octal numerals can be made from binary numerals by grouping consecutive binary digits into groups of three (starting from the right).
  Numbers with base 8 comes under octal number system. It is also called as octadecimal number system. To represent numbers in this number system it make use of 8 digits only they are digits from 0-7.
  Octal is base 8 
  0 1 2 3 4 5 6 7
   

• Base 10 Number System

  Also known as decimal number system. The base of the decimal system is 10, there are 10 symbols, 0 to 9.
  Alternatively referred to as base-10 and denary, decimal is a numbering system comprised of the numerals 0 to 9
  Decimal uses ten digits, binary uses two digits, and hexadecimal uses sixteen digits.

• Base 16 Number System

  hex (hexal / hexadecimal system),
  Hex means 16. Numbers with base 16 comes under hex number system. It is also called as hexadecimal number system. To represent numbers in this number system it make use of 8 digits only they are digits from 0-9 and letters A-F. 
  Hexadecimal is a convenient way to describe binary numbers in computers. Computers only work on the binary system, and a byte is usually defined as eight binary digits. 
  One hexadecimal digit can represent the arrangement of four binary digits. Two hexadecimal digits can represent eight binary digits or a byte.
  
  Hexadecimal is base 16.

Understanding the Binary Number System

The binary number system, or base-2 numeral system, uses only two digits: 0 and 1. Each digit in a binary number represents an increasing power of 2, starting from the rightmost digit, which represents 2^0. This system is fundamental in computing and digital electronics because it aligns with the binary logic of hardware, where circuits have two states: on (1) and off (0). Understanding binary numbers is crucial for programming, network addressing, and data representation in computer systems.

Manual Conversion: Decimal to Binary

Converting a decimal number to binary manually involves dividing the number by 2 and recording the remainder. This process is repeated with the quotient until it reaches zero. The binary equivalent is obtained by reading the remainders in reverse order. For example, to convert the decimal number 13 to binary:

1. 13 divided by 2 is 6 with a remainder of 1.
2. 6 divided by 2 is 3 with a remainder of 0.
3. 3 divided by 2 is 1 with a remainder of 1.
4. 1 divided by 2 is 0 with a remainder of 1.

Reading the remainders from bottom to top, 13 in decimal equals 1101 in binary.

Applications of Binary Numbers in Computing

Binary numbers are integral to various computing applications. Binary is used in bitwise operations, memory allocation, and low-level coding in programming. Digital electronics rely on binary for designing and analyzing circuits. Networking protocols use binary addressing, such as IP addresses, which are represented in binary form. Additionally, binary is essential in data encoding, encryption, and error detection algorithms, making it a cornerstone of modern technology.

Converting Binary Back to Decimal

Converting binary numbers back to decimal involves multiplying each binary digit by 2 raised to the power of its position, counting from right to left starting at zero, and then summing the results. For instance, to convert the binary number 1101 to decimal:

1. (1 × 2^3) + (1 × 2^2) + (0 × 2^1) + (1 × 2^0)
2. (1 × 8) + (1 × 4) + (0 × 2) + (1 × 1)
3. 8 + 4 + 0 + 1 = 13

Thus, the binary number 1101 equals the decimal number 13.

Other Number Systems: Octal and Hexadecimal

Beyond binary and decimal, other number systems like octal (base 8) and hexadecimal (base 16) are commonly used in computing. Octal uses digits 0-7, and each digit represents three binary digits. Hexadecimal uses digits 0-9 and letters A-F, with each digit representing four binary digits. These systems provide more compact representations of binary-coded values, simplifying tasks such as memory address representation and color coding in web design.
