What changes have the development of information technology brought to our lives?

There are many examples that the development of information technology has brought convenience to our lives, such as:

1. People have more and more ways to communicate with each other. Now we can not only talk and send short messages by mobile phone, but also use the Internet to send and receive e-mails, express opinions, have online discussions, and even make remote video calls through the network video function.

2. Cards that make life more convenient

Walking in the street, anyone may have a few small "cards" in his pocket, such as bank cards and transportation cards. This is inseparable from the "Golden Card" project that has been carried out for more than ten years. The "Golden Card" project is based on modern science and technology such as computer and communication, with bank cards as the medium, and through computer network system, currency circulation is realized in the form of electronic information transmission. Nowadays, all-in-one card has become the most intimate information achievement, which extends its tentacles to every detail of life, and ordinary people can always feel the convenience and speed of information. People use transportation cards to take buses, call public telephones with calling cards, spend and withdraw cash with bank cards ... In addition, there are medical cards, prepaid cards for urban utilities (such as electricity meters, gas cards, gas cards), campus cards, access cards and so on.

3. "Shooting Customers"-Changing Life with Lens

In the past, photography and news release were mostly things that journalists could do. Nowadays, digital video camera (DV) has become a consumer product that ordinary families can buy because of its low price and simple operation. The popularity of DV has changed the way people record their lives, from picture recording to video recording. Since then, video websites have spread all over the world, and everyone can upload their own works to the website for people all over the world to watch. The popularity of shooting equipment and the development of video websites have created conditions for the rise of "filming", and the "filming" culture characterized by "originality, attention and sharing" has begun to become popular on a large scale.

Information technology (IT for short) is the general name of various technologies mainly used for managing and processing information. It mainly uses application of computer science and communication technology to design, develop, install and implement information systems and application software. It is also often called information and communication technology (ICT). It mainly includes sensing technology, computer and intelligence technology, communication technology and control technology.

The research of information technology includes science, technology, engineering and management, the application of these disciplines in information management, transmission and processing, related software and equipment and their interaction.

The application of information technology includes computer hardware and software, network and communication technology, application software development tools, etc. Since the popularization of computers and the Internet, people have increasingly used computers to produce, process, exchange and disseminate various forms of information (such as books, business documents, newspapers, records, movies, TV programs, sounds, graphics, images, etc.). ).

The wide application of information technology in the world not only profoundly affects the economic structure and efficiency, but also profoundly affects the social culture and spiritual civilization as the representative of advanced productive forces.

Information technology has caused profound changes in traditional education methods. The diversity of computer simulation technology, multimedia technology, virtual reality technology, distance education technology and information carriers enables learners to overcome the obstacles of time and space and arrange their own learning time and speed more actively. In particular, distance education with the help of the Internet will open up a global knowledge dissemination channel and realize the mutual dialogue and exchange between learners and instructors in different regions, which will not only greatly improve the efficiency of education, but also provide learners with a relaxed and rich learning environment. The development of distance education will trigger a revolution in the field of traditional education and promote the general improvement of human knowledge.

Internet has become an indispensable tool for scientific research and technological development. With more than 600 large libraries, more than 400 document repositories and 1 10,000 information sources, the Internet has become a treasure house for researchers to access and obtain the latest scientific and technological trends at any time, greatly saving the time and cost of consulting documents. The rapidity and interactivity of information transmission on the Internet enable researchers anywhere in the world to become research partners, conduct real-time discussions and collaborative research online, and even use online hosts and software resources to complete their own research work.

Information network provides a more convenient channel for the spread of various ideas and cultures. A large amount of information permeates every corner of society through the network and becomes an important means of cultural communication today. Various forms of electronic publishing, such as CD-ROM, disk and online publishing, have broken the situation that paper media dominated the world in the past. The application of multimedia technology and the adoption of interactive interface have opened up broad prospects for the popularization of culture, art and technology. New information media, such as the Internet, provide new possibilities for the inheritance and dissemination of excellent cultures of all ethnic groups and for the exchange and blending of cultures of all ethnic groups. The network is changing the way of communication between people, changing people's working methods and lifestyles, which will inevitably have a far-reaching impact on the development of culture, and a new advanced culture that adapts to the network era and information economy will gradually take shape.
