Single binary flag vs ASCII character: data size comparison
The data size of an ASCII character is about 8 times the one-bit information content of a single binary flag.
BYTES OF DATA
A single binary flag is a data unit that can represent one of two possible states, such as true or false.
An ASCII character is a letter, digit, punctuation mark or control code encoded using the American Standard Code for Information Interchange.
Measurements, assumptions & sources +
Single binary flag
One-bit information content: 0.125 B; exact conversion.
A binary flag carries one bit of information, equivalent to one eighth of a byte; actual storage allocation is implementation-dependent.
One bit expressed as exactly 0.125 byte; this is information size, not the memory allocation used to store a flag.
The marked one-bit information content is calibrated. Unmeasured illustration details are representative.
ASCII character
Data: 1 B; example.
One ASCII character stored as one byte. UTF-8 characters can occupy more than one byte.

Why this measurement?
Why we use 0.125 B
We compare the one-bit information content of a single binary flag. This value follows an exact definition or conversion.
A binary flag carries one bit of information, equivalent to one eighth of a byte; actual storage allocation is implementation-dependent.
One bit expressed as exactly 0.125 byte; this is information size, not the memory allocation used to store a flag.
