The history of information technology and its applications!! Thank you!!

If you are going to use it in an information technology class, 1The development of information technology 1The generation and application of language.

2.The invention and use of writing.

3.Invention and application of papermaking and printing.

4.The invention and application of telegraph, television, and other communication technologies have brought about historic changes in the means of information transmission.

5.The application of electronic computers and modern communication technology.

2.The development trend of information technology.

1) Diversity.

2) Networking.

3) Diversification.

4) Intelligence Or the first information technology revolution is the use of language, which is an important sign of the evolution from ape to man. The second information technology revolution is the creation of words, so that the storage and transmission of information transcend the limitations of time and geography for the first time. The third information technology revolution is the invention of printing, which provides a more reliable guarantee for the accumulation and transmission of knowledge.

The fourth information technology is the invention and popularization of telegraph, radio, and television, which further breaks through the limitations of time and space. The fifth information technology revolution is the timely popularization and application of computer technology and modern communication, which has pushed human society into the digital information age. As for the application, I will take what our teacher said about sensing technology:

Infrared sensors in the factory. Automatic doors are、Automatic。

Communication technology: from the ** of the Bell era to the current visual **, from Big Brother to 3G mobile phone smart technology: generally used in factory automation. For example, IBM's "dark blue" computer, which is more powerful than international masters in chess, such as robots, etc.

Control technology: This is for example, remote control, as small as remote control, computer remote control, as large as military drones, aerospace spacecraft, planetary probes and other application fields are also very wide range of political, military, communications, transportation, scientific production, etc......

According to Marx's point of view, human history is a gradual increase in productivity from low productivity. This is very similar to the development of information technology. From the earliest Turing machines to the current PC.

It took sixty years for the hardware to go from a few rooms to a single chassis. At the same time, the development of history is staged. The development of information technology is also phased.

When we were younger, we still used the DOS system. to 98 and finally to XP and so on. It is a phased system change, but each time there is a leap.

Finally, the development of history has brought many new problems to mankind, such as environmental ecology, political democracy, and so on. Solving these new problems is another goal and a topic for the future of mankind. The same is true of information technology, smaller, faster and less error-free systems have always been the goal of our information people, but every time we solve an old one, we bring a new one.

There is nothing similar. Don't think about this aspect, if it's your homework, you can tell your tutor directly, and there is no necessary connection between the two, because there is no commonality between the two at all.

You just tell him it's okay, and just say what I said.

From ancient times to the present, information technology has undergone five major changes, each of which has produced a huge impetus for the development of human society

The first is the generation and application of language;

the second was the invention and use of writing;

the third is the invention and application of printing;

The fourth is the invention of telecommunications technology.

The development trend of information technology: diversification, networking, multi-technology, intelligence, and virtualization.

My knowledge and understanding of information technology.

1. Awareness of information technology:

In today's society, people's lives are inseparable from computers, and there are almost no people in all walks of life who do not use computers, so now as students, we must know and understand correctly.

Information technology is an essential learning program for anyone. It provides us with an opportunity to explore the unknown.

The role of the bridge, now, as long as there is a network, we can have any problems can be launched online for help, in the global scope.

Wai Nei asks for help, which is a huge resource bank. "The so-called many people rowed a big boat, and there was a lot of strength in the crowd"You won't.

People may be proficient, but human energy is limited, and it is impossible to be proficient in various affairs. So the network in information technology provides us.

A good platform for communication.

2. Some understandings of information technology:

Clause. First, the information on the network is uneven, and to maintain the tranquility of the network environment, we still need the efforts of each of us.

and create a pure network platform. This should be an information literacy issue, and everyone should do an information age bond.

French citizens.

Awareness of information technology.

Today's society is constantly developing, there are more and more peculiar things, now information technology is a new type of teaching in the current society, we should make full use of modern information technology, which is of great help to our learning. This is also the foundation for all-round development and lifelong development. We should all make appropriate use of information technology, which can not only broaden our knowledge horizons, but also stimulate our interest in learning.

Because information technology can always keep us excited, happy, and eager to improve in learning, it has a great impact on our development. It is also the cultivation of everyone's innovative consciousness and spirit of exploration, which has twice the result with half the effort.
