00000010

00000010 is an eight-bit binary numeral. As a binary string, it represents the decimal value 2 when interpreted as an unsigned integer. The same byte is written in hexadecimal as 0x02, and in binary it has only the second least significant bit set.

In ASCII and Unicode, the byte 0x02 encodes the Start of Text (STX) control character, a non-printable code used in text transmission and control protocols. Because it is a single byte, the interpretation of 00000010 can vary with context, particularly depending on how the bits are defined in a given protocol or software component.

In software development, 00000010 is commonly used as a bitmask to access or modify the second bit of a binary field. For example, testing whether this bit is set can be done with a bitwise AND with 0x02, and setting or clearing it can be accomplished with bitwise OR or AND with the complement, respectively. Bit shifting operations such as 1 << 1 also yield 00000010, illustrating how the pattern is generated from a power of two.

While it is often discussed as a simple numeric pattern, the meaning and use of 00000010 depend on the system, protocol, or programming language in which it appears. It exemplifies how an individual bit within a byte can carry a discrete flag or value.
