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.
It would be 2 raised to the power 32: 4,294,967,296.
The binary number is 11101110. A binary number represents exponential values of 2, in this case 8 digits for 128, 64, 32, 16, 8, 4, 2, and 1 238 = 128 + 64 + 32 + (0x16) + 8 + 4 + 2 + (0x1)
64 or 123

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.
256 (162)
These digits can be represented based on their Place Value Notation.
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.

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.
