TapeStore: A NEW TAPE SIORAGE SYSTEMTapeStore is a new kind of tape storage system which can store up to 6,000 computer tapes. No other tape storage system can hold as many computer tapes as TapeStore. The tapes look exactly like video cassettes. Many hundreds of data files can be stored on each tape, up to a maximum of 500 million bytes of data. If you stored the same amount of information on paper, you would need nearly 4.5 billion printed pages.The machine is a tall black box with a mechanical arm. The machine is 2.5 metres high and 3.0 metres wide. This is how it works. Each tape has a code printed on it. YOU feed the code number into TapaStore, which then looks for the code. As soon as TapaStore locates the cede, the arm reaches in and pulls out the tape.The system is very fast. It takes the mechanical arm about 10 seconds to find the tape it is looking for. The machine then searches the tape to extract the required file, and this take less than a minute. A human technician would have to locate and remove the tape by hand; and could take at least an hour to find the right file on the tape.Some of the world’s biggest companies, including banks, insurance companies, airlines, telephone companies, utilities and computer centres, have bought the system. They like it particularly because the system guarantees the security of their data.TapeStore was originally developed in Canada and is now being marketed world-wide. In Europe alone, 750 have already been installed at a cost of 480,000 dollars each. How many bytes of information san Tapestore store（）
Where did Harry spend his holiday
The past few years have been busy ones for human-rights organisations. In prosecuting the so-called war on terror, many governments in Western countries where freedoms seemed secure have been tempted to nibble away at them. Just as well, you might suppose, that doughty campaigners such as Amnesty International exist to leap to the defense. Yet Amnesty no longer makes the splash it used to in the rich world. This is not for want of speaking out. The organization is as vocal as it ever was. But some years ago it decided to follow intellectual fashion and dilute a traditional focus on political rights by mixing in a new category of what people now call social and economic rights. Rights being good things, you might suppose that the more of them you campaign for the better. Why not add pressing social and economic concerns to stuffy old political rights such as free speech, free elections and due process of law What use is a vote if you are starving Are not access to jobs, housing, health care and food basic rights too No: few rights are truly universal, and letting them multiply weakens them. Food, jobs and housing are certainly necessities. But no useful purpose is served by calling them "rights". When a government locks someone up without a fair trial, the victim, perpetrator and remedy are pretty clear. This clarity seldom applies to social and economic "rights". It is hard enough to determine whether such a right has been infringed, let alone who should provide a remedy, or how. Who should be educated in which subjects for how long at what cost in taxpayers’ money is a political question Best settled at the ballot Box. So is how much to spend on what kind of health care. And no economic system known to man guarantees a proper job for everyone all the time: even the Soviet Union’s much-boasted full employment was based on the principle "they pretend to pay us and we pretend to work". It is hardly an accident that the countries keenest to use the language of social and economic rights tend to be those that show least respect for rights of the traditional sort. The rulers of some countries habitually depict campaigns concentrating on individual freedoms as a conspiracy by the rich northern hemisphere to do down poor countries. It is mightily convenient, if you deprive your citizens of political liberties, to portray these as a bourgeois luxury. And it could not be further from the truth. For people in the poor world, as for people everywhere, the most reliable method yet invented to ensure that governments provide people with social and economic necessities is called politics. That is why the rights that make open politics possible—free speech, due process, protection from arbitrary punishment—are so precious. Insisting on their enforcement is worth more than any number of grandiloquent but unenforceable declarations demanding jobs, education and housing for all. Many do-goading outfits suffer from baying too broad a focus and too narrow a base. Amnesty used to be the other way round, appealing to people of all political persuasions and none, and concentrating on a hard core of well-defined basic liberties. No longer. By trying in recent years to borrow moral authority from the campaigns and leaders of the past and lend it to the woollier cause of social reform, Amnesty has succeeded only in muffling what was once its central message, at the very moment when governments in the West need to hear it again. According to the passage, Amnesty International
