Answer:
Hexadecimal notation is a way of representing numbers using a radix (base) of 16. Each hexadecimal digit represents four bits (binary digits), also known as a nibble. For example, the hexadecimal number 0x0C represents the bit pattern 0000 1100 in binary. Similarly, the hexadecimal number 0x3F represents the bit pattern 0011 1111 in binary.
Here are the bit patterns represented by the following hexadecimal notations:
0x0C: 0000 1100
0x3F: 0011 1111
