Each position in a decimal multidigit number will have a weighting factor based on a power of only 10.

A good example of the use of a digital representation of an analog quantity is the audio recording of music.

Binary-coded-decimal numbers use only binary numbers between 0000 and 1001.

A binary number can be converted to a decimal number by summing the decimal values of the weights of all the 1s in the binary number.

A byte has 8 bits.
