The Supercomputer Network

1 Recently, ten laboratories run bygovernments in different parts of the world have become linked. Their computershave been connected so they can "talk" to each other. This may not seem verydramatic news, but it is the beginning of a development that will increase thepower of the Internet tremendously.

2 The Internet is an interconnected（互联）system of networks that connects computersround the world and facilitates the transmission and exchange of information. Theway that you use the Internet is by accessing this network. This depends on thepower that your system allows you to use. The power of your computer isresponsible for how fast you can download（下载）files,how much data you can store, etc. If your computer is old and slow, accessingthe information can be very difficult.

3 The new development in informationtechnology has been called "the grid" （网格技术）, and it will be a network of computers that are linked together. The "grid"will work in a different way from the Internet, enabling you to get the powerof the biggest computers in the world on your computer. Accessing theinformation will no longer depend on the power of your computer. The idea isthat while you access information, you will also have access to the power ofthe bigger computer stations.

4 One advantage of this revolutionary idea isthat geographical location will become irrelevant. The "grid" will decide whichare the best parts of a worldwide network to do the job you want. This meansthat you may be accessing a computer In Japan to solve a problem in Alaska.

5 The "grid" can be compared to having anefficient personal assistant. You can give your assistant a task and"he"willdo it for you. The assistant will do the preliminary research, collect the data,compare them and decide on the best course of action by accessing any of thecomputer centres in the "grid" that happen to have the relevant information. Allyou have to do is assign the task, sit back and wait.

6 At present, possible applications of the"grid"inscientific research are being  explored. Whileit has taken about fifteen years for Internet use to become widespread, expertsbelieve that the "grid" could be up and running for private individuals farmore quickly. Scientists working on"grid"projects are convinced that it will be aswidely used as the web in the next ten years.
