64-bit microcomputer system means that the computer word length is 64 bits; a group of binary numbers processed by the computer at the same time is called a "word" of the computer, and the number of digits in this group of binary numbers is called Word length is the computer language expressed by binary code instructions. Because the instructions are a string of codes composed of 0 and 1, there are a certain number of digits, and each piece of code represents a different meaning.
The operating environment of this tutorial: Windows 10 system, DELL G3 computer.
The 64 in 64-bit microcomputer refers to the operating system word length is 64 bits,word length is binary The computer language expressed by code instructions, because the instructions are a string of codes composed of 0s and 1s, so they have a certain number of digits and are divided into long segments of several words. Each segment of coding represents a different meaning.
What is word length?
A group of binary numbers processed by the computer at the same time is called a computer's "word", and the number of digits in this group of binary numbers is called the word length. Word length is a very important technical indicator of computers. It has a great relationship with the functions and uses of computers. It also directly reflects the calculation accuracy of a computer. Many computers also have hardware costs in order to adapt to different requirements and coordinate calculation accuracy. The relationships all support variable word length operations. When other indicators are the same, the larger the word length, the faster the computer can process data.
In the computer field, word is a term used to represent its natural data unit for a specific computer design, and is used to represent a fixed length of one-time processing transactions. The number of bits in a word, that is, the word length, is an important feature in the structure of computer systems. Word length is reflected in many aspects of computer architecture and operation. Most registers in computers are one word in size. Typical numerical values processed by computers may also be in word length units. The unit of data transfer between CPU and memory is usually one word length. Also, the address used to specify a storage location in memory is often expressed in word lengths. The word lengths of modern computers are usually 16, 32, or 64 bits. Other word lengths that have been used are: 8, 9, 12, 18, 24, 36, 39, 40, 48, 60 bits; slab is another early example of a word length.
Word length is one of the main technical indicators of the CPU. It refers to the number of binary digits that the CPU can process in parallel at one time. The word length is always an integer multiple of 8. Usually PC The word length of the machine is 16 bits (early), 32 bits, and 64 bits.
The PC can process numbers of any size through programming, but the larger the number, the longer the PC will take to calculate. The maximum number that the PC can process in one operation is determined by the PC's word length.
Let’s first take a look at how the human brain performs calculations. For example, for 5×6, you can immediately get the answer to be 30, but for 55×66, it is impossible to get the correct answer immediately, which means 55 Or 66 has gone out of the "word length" of the human brain. In order to get results, complex problems (such as 55×66) must be decomposed into easy-to-handle problems (such as 55×66 can be decomposed into 50×60, 50×6, 5×60, 5×6), and then combine them to get the result.
What is a microcomputer?
Microcomputers, commonly known as computers, appeared in the 1970s and were a very important milestone in the history of computer development. Their advantages are small size, easy to carry, low price, easy to use, and have strict requirements on the use environment. It is not high and does not require a computer room for operation, which provides the possibility for the popularization of computers and promotes social development. Microcomputers are divided into workstations and personal computers. Workstations have stronger performance and more comprehensive functions. Before the 1990s, they were mainly used for scientific and technical calculations, and later they were mainly used for commercial and office purposes. Personal computers are relatively cheaper and the most convenient to use. They can be used for office, home and personal use. After 2008, the number of personal computers in the world has exceeded 1 billion.
