0b110101010

0b110101010 is a binary number, which is a base-2 numeral system used in digital electronics and computing. In this system, each digit, or bit, can be either 0 or 1. The prefix "0b" is used to indicate that the number is in binary format. The sequence "110101010" represents a specific combination of binary digits.

Binary numbers are fundamental in computer science because they are the native language of digital computers. Each bit in a binary number corresponds to a specific power of 2, starting from the rightmost bit (which is 2^0) to the leftmost bit. For example, the binary number 0b110101010 can be broken down as follows:

1 * 2^8 + 1 * 2^7 + 0 * 2^6 + 1 * 2^5 + 0 * 2^4 + 1 * 2^3 + 0 * 2^2 + 1 * 2^1 + 0 * 2^0

This calculation results in the decimal (base-10) equivalent of the binary number 0b110101010, which is 362.

Binary numbers are used in various applications, including data storage, communication protocols, and algorithm design. They are particularly useful for representing and manipulating data at the lowest level of a computer system, where each bit can be directly controlled and manipulated by hardware components such as transistors and logic gates.
