hey can help managers decide on a future course of action, and they can then help with the follow-up checks on performance to see if planned goals are being achieved. By using accurate and timely facts supplied by data base management software, a manager can do a better job of identifying problems and opportunities. And managers may not need to spend as much time in controlling when a computer can respond with a triggered report if actual performance varies from what was planned. The time saved in controlling may allow managers to give more attention to employees' concerns, and this, in turn, may result in improved morale (士气).

But employment benefits certainly aren't restricted to managers. Healthcare researchers and other scientists also use computers to conduct research into complex problem areas that couldn't otherwise be studied. Lawyers use online legal data banks to locate precedent (先前的) cases in order to serve clients better. Salespeople can receive more timely information about products in stock, can promise customers that their sales orders will be handled promptly, and can thus improve their sales performance because of the computer system. And the job duties of some office and factory workers have changed from routine, repetitive operations to more varied and appealing tasks through computer usage. For example, office workers who understand text processing, computing, and data communication usually have vital roles and are given critical office functions to perform.

Which of the following examples shows the controlling function of a computer？

A．Helping managers decide on a future course of action.

B．Helping managers check if planned goals are reached.

C．Helping managers save time in writing a report.

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. 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

C： House fires and floods are among the most devastating causes of personal computer destruction. That&39;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 house flood our burn. That&39;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&39;re not nearly far enough away should a serious disaster strike. So， it&39;s important to back up your system to a removable medium and to store it elsewhere.

D： 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&39;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.

E： 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.

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.
