0001010110100101

0001010110100101 is a 16-bit binary string commonly used in computing as a fixed data pattern. When interpreted as an unsigned integer, its value is 5541, and in hexadecimal it is 0x15A5. Because the most-significant bit is 0, the value is nonnegative in two’s complement representation as well.

In binary notation, it can be read as 0001 0101 1010 0101, grouping into nibbles for readability. This yields nibble values 1, 5, A, 5, corresponding to the hexadecimal representation 0x15A5.

Endianness and memory layout are relevant for this 16-bit value. In big-endian systems, the two bytes stored would be 0x15 followed by 0xA5. In little-endian systems, the order is reversed, with the bytes 0xA5 then 0x15.

Patterns of this kind are sometimes used as simple test vectors in digital electronics and software development to verify data paths, parity calculations, or bitwise operations. The Hamming weight (number of 1 bits) is seven, giving odd parity. The representation 0x15A5 also serves as a compact way to illustrate hexadecimal-aligned data, since the binary string maps directly to the hex digits 1, 5, A, 5.

For comparative purposes, reversing the bit order of the 16-bit string yields 1010010101010000, which is 0xA550 in hexadecimal. While the string has clear numeric value and pattern, it does not correspond to a standard text encoding or widely used textual representation.
