71,830 PointsWhat they would like you to do in each question is convert the binary number to a decimal number. Each position of a binary number is a power of 2. So 0001 is 2^0, or 1. 0010 is 2^1, or 2. 0010 is 2^2, or 4, 1000 is 2^3, or 8. Putting those values together in different ways gives all the values between 0 and 8. E.g., 1010 is 2^3 + 2^1, or 10.

12,556 PointsThe question is
What number is represented by the byte 00000001?
00000001 is a binary number. Binary means it is in base 2. The question is asking you to convert that number into a decimal number (base 10).
For Example:
00010000 is 16
00001110 is 14
10000000 is 128
