# Binary, Octal, Hexadecimal, Alphanumeric, Base 64 Number Encoder and Decoder

Binary Octal Hexadecimal Alphanumeric Base 64 No Encoding {{errorMsg}}

Binary (base 2) is the standard base for digital computers and electronic devices and it uses 2 digits, 0 and 1. Octal (base 8) uses this principle but has 8 digits, 0-7, while hexadecimal (base 16) uses 10 digits, 0-9, and 6 letters of the alphabet, A-F. Alphanumeric uses 10 digits (0-9) as well as the 26 letters of the alphabet, A-Z.

The main difference between binary, octal, and hexadecimal is the number of digits in each base. Binary has two digits while octal has eight, and hexadecimal has 16. Alphanumeric also uses 26 letters A-Z and numbers 0-9.

### What does "Binary" mean in Computer Engineering Terms?

"Binary" is a term that means "having only two alternatives." So, binary is not a language.

In computer engineering, binary refers to two states or values: 1 and 0. The binary system uses only two digits: "0" and "1". In the binary system, each digit represents a different state of being - it either has the value of "0" or the value of "1". For example, if you had a computer that was in the state of being turned on with an indicator showing that it was on at certain times during the day, then it would have a digital byte with 1 as its first digit and 0 as its second digit.

### What is Base64 Encoding?

Base64 encoding is a way to convert data into text, using only A–Z , a–z , 0–9 , + , / and = characters.

Base64 encoding is helpful for storing binary content in text-based formats, such as HTML or XML. It can also be used for transferring binary data across different systems that are not compatible with each other.

The Base64 encoding scheme uses the characters A–Z , a–z , 0–9 , + , / and =.
