0b10100101

0b10100101 is a binary number. In the decimal system, this binary representation converts to 165. The "0b" prefix is a common convention used in many programming languages and contexts to explicitly denote a number as being in binary format. The digits "10100101" are the individual bits that make up the number.

When interpreting a binary number, each digit (bit) represents a power of 2, starting from the rightmost digit as 2^0, then 2^1, 2^2, and so on, moving leftwards. For 10100101, this would be calculated as:

(1 * 2^7) + (0 * 2^6) + (1 * 2^5) + (0 * 2^4) + (0 * 2^3) + (1 * 2^2) + (0 * 2^1) + (1 * 2^0)

This simplifies to:

128 + 0 + 32 + 0 + 0 + 4 + 0 + 1 = 165.

Therefore, 0b10100101 is the binary representation of the decimal number 165. Binary numbers are fundamental to computer science and digital electronics, as they form the basis of how data is stored and processed. This particular number, 165 in decimal, could represent various types of data depending on the context in which it is used, such as a character in an encoding scheme or a value within a program.
