Why Is 1 Byte Equal to 8 Bits? [Closed]

I'ts been a minute since I took computer organization, but the relevant wiki on 'Byte' gives some context.

The byte was originally the smallest number of bits that could hold a single character (I assume standard ASCII). We still use ASCII standard, so 8 bits per character is still relevant. This sentence, for instance, is 41 bytes. That's easily countable and practical for our purposes.

If we had only 4 bits, there would only be 16 (2^4) possible characters, unless we used 2 bytes to represent a single character, which is more inefficient computationally. If we had 16 bits in a byte, we would have a whole lot more 'dead space' in our instruction set, we would allow 65,536 (2^16) possible characters, which would make computers run less efficiently when performing byte-level instructions, especially since our character set is much smaller.

Additionally, a byte can represent 2 nibbles. Each nibble is 4 bits, which is the smallest number of bits that can encode any numeric digit from 0 to 9 (10 different digits).
