11000001

11000001 is an eight-bit binary number. In unsigned form it represents the decimal value 193, and when interpreted as an eight-bit signed two’s complement value it represents −63. Its hexadecimal representation is 0xC1. In binary notation, the pattern has the two most significant bits set and the least significant bit set, with the middle six bits cleared.

In character encoding contexts, the byte 0xC1 maps differently depending on the encoding. In ISO/IEC 8859-1 (Latin-1) and Windows-1252, 0xC1 corresponds to the character Á (Latin capital letter A with acute). In UTF-8, 0xC1 by itself is not a valid standalone character; it forms the first byte of a multibyte sequence used to encode characters such as U+00C1 when followed by an appropriate continuation byte.

Common uses for the binary pattern 11000001 include its role as a bit mask or flag in low-level software and hardware programming. As a mask, it would affect bits 7, 6, and 0 while leaving other bits unchanged, depending on how it is applied in conjunction with other values. In educational settings, 11000001 is often used to illustrate binary-to-decimal and two’s complement conversions, as well as to demonstrate how different character encodings interpret a single byte.

Overall, 11000001 serves as a simple example of how an eight-bit binary value can have multiple interpretations across numeral systems, encodings, and binary operations.
