The logical judgment ability of a computer mainly depends on the compiled software; software is the interface between the user and the hardware. The user mainly communicates with the computer through software. Software is an important basis for computer system design. Electronics Computers can classify, compare, and select data according to conditions specified by people, and perform logical operations and judgment reasoning.

The logical judgment ability of a computer mainly depends on the software compiled.
Electronic computers can classify, compare, and select data according to the conditions specified by people, and perform logical operations and judgment reasoning. This "right and wrong" judgment function is similar to the simple thinking of the human brain. It is precisely these characteristics that have enabled electronic computers to develop rapidly since their advent in 1946 through the era of tubes, transistors, integrated circuits, large-scale and ultra-large-scale integrated circuits in just a few decades. The scope of application has expanded from engineering design, scientific research, economic management, etc. to all fields of human social activities.

1. The computing speed of the computer (also called processing speed) is an important performance indicator of the computer. It is usually measured by the number of fixed-point additions performed per second. Or measured by the average number of instructions executed per second, the unit is MIPS (Million Instructions Per Second), that is, millions of instructions per second. At present, the computing speed of computers has developed from thousands of operations/s in the early days to dozens of MIPs in modern computers, and supercomputers can reach tens of millions of MIPS. Such a high computing speed of computers is unmatched by any other computing tool, which greatly improves people's work efficiency and enables many complex engineering calculations to be completed in a very short time. Especially in real-time control systems that require high time response speed, the characteristics of fast computer operation can be put into full play.
2. High precision is another significant feature of computers. Data is represented internally by a computer in binary. The more binary digits, the higher the accuracy of the number. At present, the calculation accuracy of computers can reach dozens of significant figures. Theoretically, with the continuous development of computer technology, calculation accuracy can be improved to arbitrary accuracy.
3. The memory function of the computer is completed by the computer's memory. The memory can save the input original data, the intermediate results of calculation and the program. Provided to the computer system for repeated calls when needed. Memory function is the most important feature of computers that distinguishes them from traditional computing tools. With the development of computer technology, the memory capacity of computers has reached tens or even hundreds of megabytes. The external storage capacity of computers is getting larger and larger. Currently, the hard disk capacity of a microcomputer can reach dozens to hundreds of GB. The information that computers can store has also evolved from early text, data, and programs to today's graphics, images, sounds, videos, animations, videos and other data.
4. In addition to arithmetic operations, the computer's arithmetic unit can also perform logical operations such as comparison and judgment on data information. This kind of logical judgment ability is the prerequisite for computers to deal with logical reasoning problems, and it is also an important factor for computers to achieve highly intelligent information processing.
5. The working principle of the computer is "stored program control", which means that the program and data are input through the input device and stored in the memory. When the computer executes the program, it automatically and continuously follows the logical sequence of the instructions in the program. The instructions are taken out and executed in sequence, so that the process of executing the program does not require human intervention and is completely automatically controlled by the computer.
6. The operation of the computer mainly depends on the compiled software. Software is the interface between the user and the hardware. Users mainly communicate with computers through software. Software is an important basis for computer system design. In order to facilitate users and make the computer system have high overall utility, when designing the computer system, the combination of software and hardware, as well as user requirements and software requirements must be considered comprehensively.
