Eight bits have 256 permutations. This is more than enough to represent our whole digital code , in English, at least, that is, the upper and lower case alphabet, all ten numbers including zero, all common punctuation marks, and a few special characters thrown in. Eight bits equals one byte . If your modem has a capacity of 56,000 bits per second, that's often represented as 56 Kbps. That's the same as 7 KBps.
Atoms are heavy and slow.
