These digits can be represented based on their Place Value Notation.
00001. 1 turns on the value it is occupying. The values of each digit are, 1,2,4,8,16,32,64...... I you tried to get away with just 4 digits you'de end up with 15. 1+2+4+8=15. You need to step up to the 5th digit wich is 16 and reset the other digits to 0 or off.
If leading zeros are allowed (like 004 or 082), then there are 1000. Start with 000 and go to 999. If leading zeros are not used, then the lowest number is 100, so subtract off the first 100 numbers (000 through 099) so it's 900.
They make the numbers invisible to the people at Answers.com, possibly.
Boolean algebra is a division of mathematics that deals with operations on logical values and incorporates binary variables.
4 these are 00,01,10 and 11...
With 6 binary digits, you have 26 different possibilities. This is because there are two possibilities for each digit, and each digit is independent of the other digits - so you just multiply the possibilities for each digit together.
24, or 16 (0 through 15) One binary digit (bit) can have 21 values (0 or 1). Two bits can have 22 values. Three bits can have 23 values. A five-bit number can have 25 values... and so on...
256 (162)

In a computer data is represented as a series of usually binary digits. In the binary system the only numbers/values used are 0 and 1.
Because a 2-digit hex number can represent up to 256 values (including zero) - whereas the binary equivalent would require 8 binary digits (bits).. This saves space on paper.
The different digits have different values.
It is a system of representing numbers using only the digits 0 and 1, and in which the place values of digits are powers of 2.
1. A single bit can represent two different values, 0 and 1. Then simply take the largest of those two possible values, 1, and that's your answer.
Advantage of binary over decimal: information can be recorded and stored in any dichotomous variable: magnetised or not magnetised (most electronic media), pit or no pit (optoelectronic media CDs/DVDs). For decimal it would be necessary to store as 10 different levels of magnetisation or depths of pits. Not so easy to make such a system error-free. Advantage of decimal over binary: fewer "digits" required. Every ten binary digits (1024 values) can be replaced by just a shade more than three decimal digits (1000 values). So the number of digits to be stored is less than a third.
Each hexadecimal digit represents four binary digits (bits) (also called a "nibble"), and the primary use of hexadecimal notation is as a human-friendly representation of values in computing and digital electronics. For example, binary coded byte values can range from 0 to 255 (decimal) but may be more conveniently represented as two hexadecimal digits in the range 00 through FF. Hexadecimal is also commonly used to represent computer memory adresses.
