101100100

101100100 is a binary number, which is a base-2 numeral system used in digital electronics and computing. In binary, each digit, or bit, can be either 0 or 1. The number 101100100 represents a sequence of bits. To convert this binary number to a decimal (base-10) number, one would calculate the sum of each bit multiplied by its corresponding power of 2, starting from the rightmost bit (which is 2^0). For 101100100, this would be:

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

This calculation results in the decimal number 356. Binary numbers are fundamental in computer science as they are the language of digital circuits, where information is represented as a series of on/off states. The binary system is also used in various algorithms, data structures, and protocols in computing. Understanding binary is crucial for anyone working in fields related to computer science, electronics, or information technology.
