As u know, information technology is very hot nowadays. But I think some of you may still remember the days when computer is not so popular. At that time, u may feel computer and information technology is so far away from our lives if you were not a computer specialist, u would never have the chance to use a computer. Now those days has gone.
Computer has become more and more popular and You can find it everywhere in your lives. And just in our classroom, as you can see there is a computer. Our bank, factory, communication, it can help us with a lot of things. And a lot of things we use are also manufactured by computer.
Even the clothes you are wearing, they may be design by computer. which we call cad technique And many people have their own Personal Computer and to the young generation, Using a computer seems as natural as watching television or riding a bicycle. It would seem strange to us nowadays if we went into an office or a department and we find no computer. And it would be very embarrassing if u say that u have never used a computer. The fact is that computer is playing a more and more important role in our lives. It is so useful and powerful that we can not live without it.
So it is very essential to study and develop information technology. Now there are many researchers working in new theory of the next generation of computer. such as quantum computing, 64 bit cpu which is much quicker than the machine we are using now. And there are also groups working in graphics and multimedia to make media entertainment more interesting and vivid in the digital world. Such as 3 d games, virtual environment, Automatic Speech Recognition and so on. The recent work on electric data interchange will change the way people used to work.
Maybe in the near future people will only need to interact with computer instead traditional documents. The new reseach on networking and communications enable us to integrate computers as one super computer. You can share your machine to others and at the same time you can access other computers all around the world. This technique is called grid computing which is raised by ibm. There are also lots of effort made to other information technology.
These new technologies and theory can produce great improvements in economy and efficiency. Information technology is changing day by day. Amid the rapid growth in this field, we should get to know not only the technology we have developed but also need to think about the ways to go and more new technique to develop in future.
