NUMBERING SYSTEMS

OPEN AI BINARY SYSTEM The binary system is a numbering system that uses only two digits: 0 and 1. It is the fundamental basis of computers and all digital devices, as it represents the two states of a switch (on and off) in a simple and clear way. Here are some key points about the binary system: Main Characteristics of the Binary System: Base 2: Unlike the decimal system, which uses ten digits (0 to 9), the binary system uses only two digits, 0 and 1. Representation of Numbers: Each digit in a binary number is a power of [...]

sistema binario THE FUNDAMENTAL OPERATIONS IN THE BINARY SYSTEM BINARY OPERATIONS - SUM OF TWO NUMBERS I leave you a link to the previous topic Introduction to the binary system. We will deal with sum, difference and multiplication for completeness. The division is beyond the scope of this article, and when we talk about two's complement you will only use the sum. With R I have indicated the carry that occurs when both values are at 1. The carry must be immediately lined up in the column on the left, otherwise the [...]

BYTE, WORD [.....] The bit represents the unit of definition of a logic state, also defined as the elementary unit of information processed by a computer. The logical representation of the bit is represented only by the values {0, 1}. For programming purposes it is common to group sequences of bits into larger entities that can take values in much wider intervals than that allowed by a single bit. These groupings generally contain a number of binary strings equal to a binary power, ie equal to 2n; the best known is the byte (also called octet), corresponding to 8 [...]

ASCII CODING sistema binario ASCII (acronym for American Standard Code for Information Interchange) is a code for character encoding. The ASCII standard was published by the American National Standards Institute (ANSI) in 1968. In Italian it is pronounced aschi / ˈaski / or asci / ˈaʃʃi /, while the original English pronunciation is askey / ˈæski /. The initial specification based on 7-bit codes was followed over the years by many proposals for 8-bit extensions, with the aim of doubling the number of characters that can be represented. In IBM PCs, one of these extensions, now de [...]

NEGATIVE NUMBERS AND TWO COMPLEMENT sistema binario The two's complement, or base's complement, is the most common method for representing signed numbers in computer science. The expression two's complement is often used improperly to denote the negation operation (change of sign) in computers that use this method. Its enormous diffusion is given by the fact that the addition and subtraction circuits do not have to examine the sign of a number represented with this system to determine which of the two operations is necessary, allowing simpler and more precise technologies; only one circuit, the adder, is used [...]
