For example, here's a reference for fread:
size_t fread ( void * ptr, size_t size, size_t count, FILE * stream );
Reads an array of count elements, each one with a size of "size bytes"...
So how many BITS will read an fread(&x, 1, 1, stream)? Eight or CHAR_BIT?

The BYTE data type stores any kind of binary data in an undifferentiated byte stream. Binary data typically consists of digitized information, such as spreadsheets, program load modules, digitized voice patterns, and so on. The term simple large object refers to an instance of a TEXT or BYTE data type.
You can think of a byte as one letter. For example, the letter 'h' is one byte or eight bits, and the word 'hope' is four bytes or 32 bits (4*8). When looking at the size of a file, a byte is the smallest measurement size listed in operating systems.
C99, §3.6:
byte
addressable unit of data storage large enough to hold any member of the basic character set of the execution environment
and §5.2.4.2.1:
CHAR_BIT — number of bits for smallest object that is not a bit-field (byte)
Thus, a "byte" contains CHAR_BIT bits.
