11100001

11100001 is an 8-bit binary number. In decimal it equals 225, and in hexadecimal it is 0xE1. In common 8-bit character encodings such as ISO/IEC 8859-1 (Latin-1) and Windows-1252, the byte 0xE1 corresponds to the character á (Latin small letter a with acute). In Unicode, this character is code point U+00E1. In UTF-8, the character U+00E1 is encoded as the two-byte sequence 0xC3 0xA1; thus the single byte 0xE1 is not a complete UTF-8 character and is typically interpreted only within a larger byte sequence.

As a binary value, 11100001 can represent a variety of meanings depending on context, such as a data byte in a binary stream or a set of flags in a control register. Its high three bits being 1 (bits 7, 6, and 5) and the least significant bit (bit 0) set create a pattern that could be used to illustrate bitwise operations or masking examples.

In digital electronics and computing, 11100001 is used as an example of an 8-bit pattern or as a literal in programming and debugging, memory dumps, and communication protocols. It encapsulates how binary data is often interpreted differently across systems.
