1010010101010000

1010010101010000 is a 16-bit binary sequence. In computing, such fixed-width binary strings are commonly used as literals or bit patterns in software, hardware descriptions, and teaching materials.

Its value depends on interpretation. As an unsigned integer, 1010010101010000 equals 42320 in decimal and 0xA550 in hexadecimal. If interpreted as a 16-bit signed two's-complement value, it represents -23216.

Structurally, the sequence breaks into four 4-bit blocks: 1010 0101 0101 0000, corresponding to the hexadecimal digits A, 5, 5, 0. The pattern begins with an alternating bit sequence, includes a repeated 0101 segment, and ends with a run of zeros.

Its uses are typical of binary literals and bit-pattern examples: demonstrating base conversions, testing bitwise operations, masking, endianness demonstrations, or serving as a simple memory-initialization example in digital design.

Note that the most significant bit is 1, which affects signed interpretation. If split into bytes, the two 8-bit values are 0xA5 and 0x50.
