I would like to share with you what are the three ways to express the number of computer machines. I hope you will get something after reading this article. Let's discuss it together.

The three representation methods of computer machine number are original code, inverse code and complement code; machine number is the number that "digitizes" the symbol and is the binary representation of number in computer; machine number has two characteristics: the digitalization of symbols and the size of their numbers are limited by the machine word length.

The three representations of the number of computer machines are original code, inverse code and complement code.

The machine number is the number that "digitizes" the symbol and is the binary representation of the number in the computer. The number of machines has two characteristics: one is the digitalization of symbols, and the other is that the size of the number is limited by the machine word length.

Characteristics

The number of machines has two basic characteristics:

1. Symbolic numeralization of numbers. Practical data have positive and negative numbers, because the hardware inside the computer can only represent two physical states (represented by 0 and 1), so the positive sign "+" or negative sign "-" of practical data is distinguished by a binary 0 or 1 in the machine. Usually this symbol is placed in the highest bit of a binary number, called a symbol bit, with 0 for the symbol "+" and 1 for the symbol "-". Because a symbol occupies a bit, the formal value of the number is not equal to the real value, and the value corresponding to the number of machines with symbolic bits is called the true value of the machine number. For example, the binary truth number-011011, its number of machines is 1011011.

2. The number of binary bits is limited by machines and equipment. The number of binary digits that can be represented by the internal equipment of the machine at one time is called the word length of the machine, and the word length of a machine is fixed. The 8-bit word length is called a Byte, and the machine word length is generally an integral multiple of the byte, such as 8-bit, 16-bit, 32-bit, 64-bit.
