10101111011

10101111011 is an 11-bit binary string. In unsigned binary interpretation, it represents the decimal value 1403, and in hexadecimal it corresponds to 0x57B.

If interpreted as an 11-bit two's-complement signed integer, the value is 1403 − 2048 = −645. This reflects how the same bit pattern can denote different numbers depending on the chosen representation.

Pattern and structure notes: the sequence contains a run of four consecutive ones in the middle (1010 1111 011). The string begins and ends with the digit 1, and it is not a palindrome.

Potential usage: such binary strings are common as literals or test patterns in digital design, programming, and communications. They may be used to represent small integers, bit masks, or pattern data in examples and documentation. On its own, 10101111011 does not encode a widely recognized symbol or standard, but it can serve as a compact illustration of binary notation and different numeric interpretations.

Related concepts include binary numbers, hexadecimal notation, and two's-complement representation, which together describe how binary strings map to integer values in computing systems.
