00000001

00000001 is an eight-digit binary numeral. In binary notation it is 0b00000001, which equals the decimal value 1 and the hexadecimal value 0x01. The string is frequently used to represent a single set bit, particularly the least-significant bit, in computing and digital electronics.

In programming, the value 1 is often used to indicate true or an enabled state in contrast

In ASCII and character encoding, the byte 00000001 corresponds to the control code Start of Heading (SOH)

In memory and data representation, 00000001 is used in little-endian systems to denote the value 1 when
