0x105D

0x105D is a hexadecimal numeral commonly seen in computing and programming. The prefix 0x signals that the digits following are base-16. In decimal, 0x105D equals 4189; in binary it corresponds to 0001 0000 0101 1101. This value may be used as a data word, an address, or a flag in various software and hardware contexts.

In source code, 0x105D typically appears as a numeric constant. Depending on the context, it may serve as a straightforward value, a bitmask, or a memory or I/O address. How it is interpreted depends on the architecture (endianness, bit width) and the language rules; for example, in little-endian systems the 16-bit value 0x105D would be stored as the bytes 5D and 10, in that order.

Because hex literals are context-dependent, 0x105D rarely has a universal meaning outside a particular specification, data sheet, or source file. As with any such constant, its meaning is defined by the surrounding code, the hardware documentation, or the protocol in which it appears.
