How integer is stored in memory

In the example showing how integer will be stored in memory,
if 1 byte = 8 bits then why cannot we store 15 in a single cell simply as 15 needs only 4 bits.

@paras.bisht 15 is one of the the integer but what if you want to store a big integer like 1e9 , you cant store it in 4 bits thats why generally 32 bits (4 bytes) are used.
i hope its clear if yes dont forget to hit like and mark resolved :smiley:
