It is obvious that we are entering the digital age. Modern electronic information system has been inseparable from the processing of discrete information digital circuit, digital circuit has high stability, high reliability and many other advantages, making its application more and more extensive, such as digital computers, advanced communication systems and so on. The rapid development of digital technology and its wide application are breathtaking.
There are three major milestones in the development process of network technology, which make the perfect integration of computer and communication technology, and formed a very effective information network. The first is the basis of packet switching. This technology effectively realizes the sharing of equipment and information resources, which comes into being with the development of information communication. Second, an open system Internet reference model is constructed. This system pattern appeared in the period of the Internet, promote the healthy development of network technology, and the third is our most familiar with, which is Internet, the Internet is the largest computer network of the most widely used.
Nowadays, the development of computer technology and Internet is so fast. I have to thank the people and things behind the scenes that are driving these developments. One of the people who impressed me most was “the world’s first programmer” Ada Lovelace. The meeting of Ada and Babbage laid the foundation for the design of the Analytical Engine, and Ada enriched the designs of Babbage and others at the time. The notes from her on the article describes the analysis and how to program so that people could understand the working principle of the machine through a complete demonstration. And the next one, has had a major impact on my life. In 1982. Dr. Marc Hannah and other computer scientists formed SGI INC. This is a very influential computer graphics company, specializes in software and hardware used to create cutting-edge 3D illustration and effects. Although the company ended in 2009 due to advances in low-cost graphics solutions, it laid the technical groundwork for the special effects development of many subsequent films, such as Jurassic Park and Terminator 2.
It’s not just people, some other factors also contribute to computers. One of these is the emergence of regular continuity of creative activity. First, continuous innovation was driven by demand, and it was the urgent need for information during World War II that reduced barriers to creation, made resources available for basic technological experimentation, and promoted the emergence of computers in their early stages. For example, during World War II, molecular spectroscopy flourished because of the need for radar, and the research frontier moved toward shorter wavelengths. Historically, the invention of the maser was born out of the research problem of molecular spectroscopy.
It is these people and various factors to promote the emergence and development of computer technology and digital technology, and the emergence of digital technology and the Internet to our life has brought convenience.
