101010001

101010001 is a nine-digit binary string. In decimal notation, it equals 337, and in hexadecimal it is 0x151.

As a bit pattern, it is 101010001, featuring a run of three consecutive zero bits before the least significant bit.

In computing contexts, such binary strings may be used as data patterns, test vectors, or identifiers. They can appear in memory dumps, file contents, network frames, or educational examples that illustrate base-2 representation.

Because it spans nine bits, it does not align with a single 8-bit byte, but it can be stored in wider data containers such as 16- or 32-bit integers.
