10001101

10001101 is an eight-bit binary string commonly used to represent a byte in computing. As a pattern of ones and zeros, it can be interpreted in several ways depending on context, such as numeric value, character encoding, or bitwise operations.

As an unsigned binary number, 10001101 equals 141 in decimal, and 0x8D in hexadecimal. The bit pattern contains four ones, giving a Hamming weight of 4. If interpreted as an eight-bit two's complement value, the same pattern represents −115.

In character encoding schemes derived from ASCII, the byte 0x8D is not a printable character. In ASCII-compatible encodings such as ISO/IEC 646, it is typically a control code, and in extended encodings like Latin-1 or Windows-1252 it also maps to a non-printable control value rather than a standard symbol.

Practical uses of the pattern include representing data in memory, outlining bit masks or flags, and serving as an example in discussions of binary arithmetic and low-level programming. As with any eight-bit pattern, its interpretation depends on the surrounding system’s data format and interpretation rules.
