Preparing for Computer Disasters

We use them to communicate, shop, and do homework, and they're even more vital to home office users. When home office computers go down, many small businesses grind to a halt. Fortunately, taking steps to recover from disasters and minimize their effects is quite straightforward. With a good offsite storage plan and the right tools, you can bounce back quickly and easily from minor computer disasters. And, should a major calamity strike, you can rest assured your data is safe.

Offsite Storage: Major Disasters

House fires and floods are among the most devastating causes of personal computer destruction. That's why a solid offsite backup and recovery plan is essential. Although many home users faithfully back up their hard drives, many would still lose all their data should their houses flood or burn. That's because they keep their backups in relatively close to their computers. Their backup disks might not be in the same room as their computers-tucked away in a closet or even the garage-but they're not nearly far enough away should a serious disaster strike. So, it's important to back up your system to a removable medium and to store it elsewhere.

There are many ways to approach offsite storage. It starts with choice of backup tools and storage medium. Disaster situations are stressful, and your recovery tools shouldn't add to that stress. They must be dependable and intuitive, making it easy to schedule regular backups and to retrieve files in a pinch. They must also be compatible with your choice of backup medium. Depending on your tools, you can back up to a variety of durable disk types--from CDs to Jaz drives to remote network servers. Although many of these storage media have high capacity, a backup tool with compression capabilities is a big plus, eliminating the inconvenience of multiple disks or large uploads.

Once you select your tools and a suitable medium, you need to find a remote place to store your backups. The options are endless. However, no matter where you choose, be sure the site is secure, easily accessible, and a good distance away from your home. You may also want to consider using an Internet-based backup service. More and more service providers are offering storage space on their servers, and uploading files to a remote location has become an attractive alternative to conventional offsite storage. Of course, before using one of these services, make certain you completely trust the service provider and its security methods. Whatever you do, schedule backups regularly and store them far away from your home.

prepared on computers, and exist as computer files before they are printed on paper. Often there are advantages to give readers access to the electronic versions of publications as well as, or even instead of, the printed versions.

Print publications have lots of advantages. Paper is pleasant to handle, easy to read, and very portable. you can read it almost anywhere. On the other hand, print has its weaknesses. Paper is expensive, and articles are often cut to fit the space available. Printing and distributing paper is expensive and takes time. Printed materials are expensive to store and almost impossible to search. Electronic publishing offers solutions to all these problems.

Suppose a publisher makes the electronic copy of a newspaper or magazine available from the net, perhaps on the Internet's World Wide Web. No paper is used and disc space is cheap, so Internet publishing costs very little. Articles don't have to be cut (though there is of course a limit to the amount people are willing to read online). Internet publishing is fast, and readers can access material as soon as it becomes available: within minutes, instead of the next day, next week or next month. Internet publishing goes beyond geographical boundaries: the humblest local paper can be read everywhere from New York to London to Delhi to Tokyo. Delivery costs are low because there are no newsagents to pay, and no postal charges: readers pick up the bills for their on-line sessions. Also, computer-based publications are simple to store (on disc) and every word can be searched electronically.

At the moment, newspapers and magazines, TV and radio stations, news agencies and book publishers are making content freely available on the Web because they are competing for "mindshare". Perhaps they want to find out if they can attract and hold an audience online, or perhaps, they're afraid of missing out because "everyone else is doing it". But don't count on things staying that way: Publishers are not in business to lose money.

What does the author probably foresee？

A．Readers will have more accesses.

B．Books and newspapers will be kept as computer files.

C．It will not make any sense to keep the printed versions.

D．Electronic publications will replace printed ones.

Preparing for Computer Disasters

A： Summary： When home office computers go down， many small businesses grind to a halt. Fortunately， taking steps to recover from disasters and minimize their effects is quite straightforward.

B： Fires， power surges， and floods， they&39;re all facts of life. We read about them in the morning paper and see them on the evening news. We sympathize with the victims and commiserate over their bad luck. We also shake our heads at the digital consequences—melted computers， system failures， destroyed data. Yet， somehow， many of us continue to live by that old mantra of denial： "It won&39;t happen to me." Well， the truth is， at some point you&39;ll probably have to deal with at least one disaster. That&39;s just how it goes， and in most aspects of our lives we do something about it. We buy insurance. We stow away provisions. We even make disaster plans and run drills. But for some reason， computer disaster recovery is a blind spot for many of us. It shouldn&39;t be. Home computers contain some of our most important information， both business and personal， and making certain our data survives a disaster should be a priority. Moreover， even the smallest disaster can be a serious disruption. Personal computers have become an integral part of the smooth-running household. We use them to communicate， shop， and do homework， and they&39;re even more vital to home office users. When home office computers go down， many small businesses grind to a halt.

Come What May： Handling the Garden Variety Computer Crisis

F： Not all home computer damage results from physical disaster. Many less menacing problems can also hobble your PC or destroy your information. Systems crash， kids "rearrange" data， adults inadvertently delete files. Although these events might not seem calamitous， they can have serious implications. So， once again， it&39;s important to be prepared. As with physical disasters， regular backups are essential. However， some of these smaller issues require a response that&39;s more nuanced than wholesale backup and restoration. To deal with less-than-total disaster， your tool set must be both powerful and agile. For example， when a small number of files are compromised， you may want to retrieve those files alone. Meanwhile， if just your settings are affected， you&39;ll want a simple way to roll back to your preferred setup. Yet， should your operating system fail， you&39;ll need a way to boot your computer and perform. large-scale recovery. Computer crises come in all shapes and sizes， and your backup and recovery tools must be flexible enough to meet each challenge.

The Right Tools for the Right Job： Gearing up for Disaster G： When disaster strikes， the quality of your backup tools can make the difference between utter frustration and peace of mind. Symantec understands this and offers a range of top quality backup and recovery solutions. Norton GoBack is the perfect tool for random system crashes， failed installations， and inadvertent deletions. With this powerful and convenient solution， it&39;s simple to retrieve overwritten files or to bring your system back to its pre-crash state. Norton Ghost is a time-tested home office solution. Equipped to handle full-scale backups， it&39;s also handy for cloning hard drives and facilitating system upgrades. A favorite choice for IT professionals， it&39;s the ideal tool for the burgeoning home office. You can buy Norton Ghost and Norton GoBack separately， or get them both when you purchase Norton System Works.

H： Life&39;s disasters， large and small， often catch us by surprise. However， with a little planning and the right tools， you can reduce those disasters to bumps in the road. So， don&39;t wait another day. Buy a good set of disaster recovery tools， set up an automatic backup schedule， and perform. a dry run every now and again. Then， rest easy.

ds of everyday perceptions, the bases for the decisions we make, and the roots of our habits and skills are to be found in our past experiences, which are brought into the present by memory.

Memory can be defined as the capacity to keep information available for later use. It includes not only "remembering" things like arithmetic or historical facts, but also involves any change in the way an animal typically behaves. Memory is involved when a rat gives up eating grain because he has sniffed something suspicions in the grain pile. Memory is also involved when a six-year-old child learns to swing a baseball bat.

Memory exists not only in humans and animals but also in some physical objects and machines. Computers, for example, contain devices for storing data for later use. It is interesting to compare the memory-storage capacity of a computer with that of a human being. The instant-access memory of a large computer may hold dp to 100,000 "words"—ready for instant use. An average U.S. teenager probably recognizes the meaning of about 100,000 words of English. However, this is but a fraction of the total amount of information which the teenager has stored. Consider, for example, the number of faces and places that the teenager can recognize on sight.

The use of words is the basis of the advanced problem-solving intelligence of human beings. A large part of a person's memory is in terms of words and combinations of words.

According to the passage, memory is considered to be ______.

A．the basis for decision making and problem solving

B．an ability to store experiences for future use

C．an intelligence typically possessed by human beings

D．the data mainly consisting of words and combinations of words

听力原文： Although the first computers were produced for use in government and industry, they have become common in other areas during the past 25 years.

In business, computers perform. many functions. They are used to perform. the data processing operations of recording, classifying, sorting, computing, storing, reporting, reproducing and communicating information. They have the advantage of being able to complete these processes at very high speeds. Computers also can process data in a size invisible in the human eye, making storage of materials a simpler task than it once was.

Universities utilize computers in several ways. Just as business stores statistical data, universities store statistics about students using computers. Registration also has been aided by the computer. By putting their programs of studies on the computer, students can find out immediately which classes are open for additional students and which already have the number that are allowed to register. Many professors use computers in their research, and experiments have been done on teaching by means of the computer.

Computers have also been affecting our daily lives more and more. Most large departments and grocery stores now have computerized cash registers. Almost everyone is familiar with the computerized hilling that is done on the large expressways. It is even possible today to buy your own computer and use it in your home.

The Virtual Shopping Mall

People buy things, items, for different reasons. They buy the products because they need them or just because they want them. People go shopping: they look around at different stores to find good deals. They "comparison-shop." In other words, they look at the same product in several stores or from several manufacturers. Then they choose to purchase the best products for themselves—their favorite ones or the ones with the lowest prices. However, many people shop because they enjoy shopping. They like to walk through stores looking at products. They think about the products, and sometimes they buy them. Today shoppers have many ways that they can go shopping.

People used to go to the local market to do their shopping. They went from store to store to find the products that they wanted or needed. At the meat market, customers bought meat, and at the bakery, they purchased bread. At the department store, consumers looked at the attractive' displays in the windows and on the racks. They bought television sets and VCRs at the appliance store. Shoppers went from store to store comparing the products and the prices. Then they made their decisions, and they bought items. They shopped for other products in other stores, such as grocery stores, pharmacies, hardware stores, or flower shops. The owners of the stores advertised their products to compete for business. In small towns, shoppers may still shop this way.

Now, however, shoppers have several choices when they want to purchase products. They may go to the shopping mall, where there are many stores in the same place under the same roof. They can park their cars in the large parking lot and do all their shopping in one stop. Also, they probably study newspaper advertisements in the morning before they go to the mall. The ads inform. them about special sales, or bargains. In the newspaper, sometimes these shoppers find discount coupons for special sales. They are ready to make rational decisions about their purchases. The shopping mall is very convenient for many people. On the other hand, other consumers shop by mail. They get catalogs and advertising flyers from manufacturers in their mailboxes. At home, they look at the displays of items on the pages in the catalogs. The catalogs show colorful pictures of the products. There are also written descriptions of the items. These descriptions tell the buyer about the materials in the product, the sizes, the colors, and the prices. The consumers analyze the products and make decisions. Then they mail their orders to the manufacturer, or they use the telephone to place their orders. Shopping by catalog is another convenient way for the consumer to go shopping.

Modern technology has added other ways for people to shop. Shoppers can now shop for products and services from their homes. On their television sets, viewers can choose a shopping channel. These channels are like catalogs on TV. For example, shoppers see models wearing the clothes or jewelry. They can watch a salesperson demonstrate a video camera. Or they can see a salesperson cook a meal on a special kind of kitchen appliance. The products seem to come alive and be real, not just pictures on a page in a catalog. It is easy to purchase the items. The buyers order the items by calling a number on the telephone and giving their credit card numbers. Sometimes the buyer can pay for the item in several installments. The business sends the product to the consumer through the mail. Many buyers are vulnerable because it is so easy to shop this way. They use their credit cards quickly, and soon they have large bills to pay.

Another way shoppers use technology is on their computers. They use ecommerce. Using a computer, they shop for products and services across the country and around the world. People use computers to help them keep track of their money. For example, they do their banking an
