Also in the information environment, there is such a concept as a machine word - this is the minimum unit of data, which is sixteen bits, that is, two bytes. Why is that? The point is that a unit of information in computer science is a bit. So, the hexadecimal number system, as the name implies, is based on the number 16. The method of representing numbers in binary format is studied in the 8th grade computer science course. The number system in which only two digits are used to represent numbers is called binary. Information in a computer is processed in digital format, in the form of a set of zeros and ones, so all numbers are converted to binary form. In this case, the writing of a positive number does not change for any of the codes. And in order to carry out any operation with them in binary code, it is necessary to represent it in the form of an additional code. In the binary system, there is also the concept of negative numbers. In addition, the binary system is the most convenient for quick translation into other number systems. However, this does not complicate the performance of arithmetic operations at all.
The alphabet of the binary number system consists of only two characters: 0 and 1. The base of this system is two, that is, only two characters are used to write numbers. Binary system is one of the types of positional number systems.
