dvojková

Dvojkova, also known as binary, is a base-2 numeral system used in digital electronics and computing. It represents numeric values using only two symbols: 0 and 1. Each digit in a binary number is called a bit. The position of each bit represents a power of 2, starting from the rightmost bit (which represents 2^0 or 1) and increasing to the left. For example, the binary number 1011 represents the decimal number 11, calculated as (1*2^3) + (0*2^2) + (1*2^1) + (1*2^0).

Binary is widely used in computing because it aligns with the two-state nature of electronic circuits, where a signal can be either on (1) or off (0). This makes binary an efficient and reliable system for data representation and processing in digital devices. Binary numbers can be converted to other numeral systems, such as decimal, hexadecimal, and octal, using mathematical algorithms. The binary system is fundamental to understanding and working with digital technology.
