Lesson

Binary data is base 2 as in 1's or 0's

a bit is 1 number, 4 bits are a nibble and 8 bits are a byte

Kilobyte=1024 bytes because it is 2^10

6). What is base 10 base 2 and base 16? Denary, binary, hexadecimal

7). Hexadecimal is used to convert binary because each character represents a nibble

8). Write a simple Python program that works out bits/bytes or converts binary to denary or hexadecimal
