The basic goal of a computing machine is to be able to execute general arbitrarily complex calculation rules. A computing machine can perform numerical calculations, logical calculations, and has storage and memory functions; it is a modern intelligent electronic device that can run according to a program and process massive amounts of data automatically and at high speed.
The operating environment of this tutorial: Windows 7 system, Dell G3 computer.
The basic goal of a computing machine is to be able to execute general arbitrarily complex calculation rules.
Main features:
Fast computing speed: The computing speed of today’s computer systems has reached trillions of times per second, and microcomputers can also reach hundreds of millions per second times or more, enabling a large number of complex scientific computing problems to be solved. For example: the calculation of satellite orbits, calculations of large dams, calculations of 24-hour weather forecasts, etc. In the past, manual calculations took years or decades, but now computers can be completed in just days or even minutes.
High calculation accuracy: The development of science and technology, especially the development of cutting-edge science and technology, requires highly accurate calculations. The reason why computer-controlled missiles can accurately hit the predetermined target is inseparable from the precise calculation of the computer. A general computer can have more than a dozen or even dozens of (binary) significant digits, and the calculation accuracy can range from a few thousandths to a few millionths, which is beyond the reach of any computing tool.
Ability to make logical judgments: As computer storage capacity continues to increase, more and more information can be stored and memorized. The computer can not only perform calculations, but also save the data, programs, intermediate results and final results involved in the calculation for users to call at any time; it can also process various information (such as language, text, graphics, images, music, etc.) Coding technology performs arithmetic and logical operations and even reasoning and proofs.
Have automatic control capabilities: The internal operations of the computer are automatically controlled according to the programs programmed by people in advance. Users design the operating steps and programs in advance based on their problem-solving needs. The computer operates very strictly according to the steps specified in the program. The entire process does not require manual intervention and is executed automatically, achieving the user's expected results.
