Perhaps a food analogy might help you remember the difference between 
byte and bit.


If you aren't hungry you may just nibble a bit (bit) at your food



Actually a "nibble" is 4 bits : https://en.wikipedia.org/wiki/Nibble

I believe this is the proper analogy.

1 binary digit is 1 bit: B_inary dig_IT. Values are 0 and 1.
4 bits is a nybble, and has the values 0 thru 15 (2^4-1). These are coded
as 0-9,A-F in hexadecimal (6+10).
8 bits or 2 nybbles are a byte, with the values 0-255 (2^8-1), coded as 00
thru FF. Also called an octet.*

In C a stray backslash may cause you to accidentally run into octal
numbers, being the 3 bits 0-7 representing base-8, but these are best left
in the dustbin of history.

* Today, a byte being 8-bits is mostly by convention. In the dark ages of
computing there were also 6-bit bytes (2 octals, being 2 of the 3-bit octal
numbers 0-7, not the 8-bit octets) and other odd combinations that are also
best forgotten.

If you aren't hungry you may just nibble a bit (bit) at your food but when 
you are hungry you will be take a bite (byte) of the food.


From that you should be able to visualize the difference that is smaller 
than a byte.
