The status and role of computers in information technology 30

1. Entertainment For most people in China, entertainment comes first when buying PDA. So it's okay to watch movies, listen to **, read comics, and use it to play games, install a GBA simulator, ** some GBA games to play, it's not bad. In addition, find small, intellectually tested games to play, such as Sokoban, to kill time.

2. Learning PDA is still very useful for students and many people who want to study further. It can be used to memorize words and read study materials, which is better than taking a book everywhere. It is used to memorize words and read English articles, and the effect is good.

Look up the dictionary and the real person speaks. The vocabulary is n times larger than all electronic dictionaries, including a variety of languages.

3. Reading books The vast majority of people buy PDA just to read books, they don't have to take most of the books everywhere, and they can be lazy to read at work and class, which is very convenient. Many books can be turned into e-books, and it is very convenient to get them and read them. You can also bring some full-color 18x comics with you.

4. Notes can be used to arrange the itinerary and remember important things. It is convenient for busy business people to replace the secretary.

5. Internet access It is already very convenient to use PDA's infrared interface, Bluetooth, and WIFI wireless network to access the Internet. And the Internet speed with wifi is so fast, it already feels the same as the computer Internet access. There are more and more places where wifi is located, and it is believed that it will become the most popular means of communication within the year.

6. Address book.

There are many people who are using this function, and it is much easier to look it up.

7. The PDA used by remote control should be infrared, and through the learning function, other remote controls in the family can be retired. You can also play a prank by remotely controlling other TVs on the street.

8. Some PDAs in mobile phones already have ** functions.

9. Digital camera.

There are also some PDAs that have cameras, and the number of pixels has gone up to 2 million. It is enough to replace the general lightweight DC, and it is no problem to go to the sun.

10. Applications.

PDA's software has developed very maturely, and many of the same software needs to be adapted to individual needs. A wide range of uses have spread to every class and every field.

11. Miscellaneous.

Of course, it can be used as a portable hard drive.

It's better to ask here than to look it up on the Internet yourself

Computer science and technology are in a leading position, and their role is to promote China's economic development.

Computer Science and Technology (CS), as the name suggests, is a discipline that learns scientific principles and professional techniques related to computers. In a broad sense, a computer is a machine that calculates and outputs input information, and computing itself can be regarded as a process of processing information.

Extended Materials. Computer Science and Technology is an undergraduate major in ordinary colleges and universities, which belongs to the computer class.

Specialized. This major cultivates high-level professionals with all-round development in moral, intellectual and physical aspects, mastering the basic knowledge of mathematics and natural sciences, as well as the basic theories, basic knowledge, basic skills and basic methods related to computers, networks and information systems, with strong professional ability and good comprehensive quality, and can be competent for computer science research, computer system design, development and application.

Internationally majored in Computer Science and Technology.

Talent training started in the United States in the 50s of the 20th century, and by the 60s, professional education gradually entered the track of scientific research, teaching content and curriculum system.

The reference scheme proposed by the academic community is adopted.

Since the mid-20th century, other countries, including China, have adopted a teaching program for computer science and technology majors.

Basically, they are all based on the American system.

Ministry of Education of the People's Republic of China, 1995.

Launched a research plan on the reform of the teaching content and curriculum system of higher science for the 21st century, and approved the reform of the curriculum system of computer science and technology majors, which was established by Fudan University.

and other nine schools formed a project team to conduct research, and put forward the idea of classifying and grading students majoring in computer science and technology.

At the end of the 90s of the 20th century, China launched the construction project of 35 key university demonstration software colleges, trying to explore the training goals and methods of software application talents specializing in computer science and technology.

We know that some of the important features of the 21st century are digitization, networking and informatization, and it is an information age with the network at its core. In order to realize informatization, it is necessary to rely on a well-developed network, because the network can transmit information very quickly. Therefore, the Internet has now become the lifeblood of the information society and an important foundation for the development of the knowledge economy.

The Internet has had an immeasurable impact on many aspects of social life and on socio-economic development. There are three types of networks that everyone is familiar with, namely telecommunication networks, cable television networks, and computer networks. According to the initial division of services, the telecommunications network provides users with services such as **, telegraph and fax.

Cable television networks deliver a variety of television programs to their subscribers. Computer networks, on the other hand, enable users to transfer data files between computers. These three types of networks play a very important role in the process of informatization, but the fastest growing and central one is the computer network, and this is what this book will discuss.

With the development of technology, telecommunication networks and cable television networks have gradually integrated into the technology of modern computer networks, expanding the scope of the original services, and computer networks can also provide users with the services of communication, communication and transmission of programs. Theoretically, the integration of the above three networks into one network can provide all the above services, which is the "triple play" that has been proposed a long time ago. However, the truth is not so simple, as it involves various issues of economic interest and administrative jurisdiction.

Since the 90s of the 20th century, the computer network represented by the Internet has developed rapidly, and has gradually developed from the initial free education and scientific research network for the use of Americans only to the commercial network (paid use) for global use, and has become the largest and most important computer network in the world. It is no exaggeration to say that the Internet is the biggest revolution in the field of storing and exchanging information since the invention of the printing press.

The core of modern information technology is computer manufacturing technology.

Function: Efficient document arrangement, processing, the emergence of the database provides a convenient processing tool for the growth of information in today's society (data saving, modification, query, deletion, etc.).

Status: The core of information technology.

Function: Efficient document arrangement, processing, the emergence of the database provides a convenient processing tool for the growth of information in today's society (data saving, modification, query, deletion, etc.).

The computer is the creation that had the greatest impact on human beings in the 20th century, and its emergence has brought great changes to people's lives, especially after the development of the network, human communication has become extremely easy, and the transmission of knowledge has become extremely fast.

The role of computers: In the early days, computers were used for scientific calculations, and later computers were slowly applied to the first institutions, schools, and commercial fields for transaction processing. Computers can efficiently arrange and process documents, and the emergence of databases provides a convenient processing tool for the growth of information in today's society (data saving, modifying, querying, deleting, etc.).

The computer is not connected to the Internet, but it can also be used for entertainment, movies, **, games (standalone, LAN) can be. At the same time, you can also study, install software on the computer, you can program, you can calculate math problems, you can write literary works. In a factory, computers can control machines in real time or asynchronously, and so on.

Status is unattainable. It can't be shaken. The role is used in all aspects of work and life. For example, you can't go to the bank to withdraw money without it.

Computers act as people's hands, eyes, ears, and information without boundaries, and are indispensable in life.

The status is very high, and the role is also great!Indispensable!
