10010101

10010101 is an eight-bit binary string, i.e., a byte, commonly used in computing to represent raw data, flags, or small integers. It can be interpreted in different ways depending on the context.

As an unsigned value, 10010101 equals 149 in decimal. In hexadecimal, this byte is 0x95. When interpreted as an eight-bit signed value in two’s complement, the same pattern represents -107.

The pattern is widely used in education and practice for illustrating binary arithmetic and bitwise operations such as AND, OR, XOR, and bit shifting. It also serves as a standard test pattern in hardware communication, data encoding demonstrations, and basic memory or register examples.

Character encoding notes: the byte 0x95 maps differently across encodings. In Windows-1252, 0x95 corresponds to the bullet character (U+2022). In ASCII and ISO/IEC 8859-1, the range 0x80–0x9F consists of control codes, so 0x95 is not a standard printable ASCII character.

Overall, 10010101 functions primarily as a concise, illustrative binary sequence that demonstrates how a single byte can encode various numeric and symbolic meanings depending on interpretation and encoding used.
