Most companies expect IT (Information Technology) managers to head an IT staff of computer technicians. But IT managers can also specialize in other areas. Some managers may also be responsible for keeping their company’s Internet safety. They protect both their company and their online customers from thieves.

Other managers focus more on the business rather than the technical part of computing. They become project managers, helping companies reach as many online customers as possible.

Some companies also look for IT managers who can act as trainers. These trainers help a company’s computer technicians keep up-to-date on computer skills.

Most companies require their IT managers to have both a bachelor’s degree and some experience in the computer field. Often, companies hire IT managers out of their existing staff of computer technicians.

Since IT managers are extremely important to companies’ success, it’s no surprise that they receive such high salaries – around US $56,000 a year to start with. And, in such a fast-changing field,

managers’ salaries usually increase after only a couple of years.

The world will be watching to see just how quickly e-commerce replaces the old ways of doing business. And as computers change the way the world does business, IT managers will be in the middle of it all. Few companies can survive without them.

Besides being the leader of computer technicians, IT managers are also expected to be ________.

(A) experienced product designers

(B) skilled online technicians

(C) doctorate holders

(D) online safety specialists

example, gives rise to organized opposition, information technology, which is actually no less invasive (侵害的) ,no more harmless, is welcomed or, at the least, accepted with comparatively little debate. Information technologies from computers and communications ---- have obviously had an overwhelming social impact and their benefits hardly need explanations, but they have also disturbed privacy and threatened civil liberties, computerized data banks empower bureaucratic authorities by providing easy access to personal information-about credit ratings, social performance, housing and medical histories. They will allow access to genetic figures, providing information about our tendencies to employers, insurers, product advertisers, banks and other institutions that exercise control over our lives. Computerization allows the severe extension of advertising through telemarketing requests that shamelessly intrude our home life. Information technologies have displaced people from jobs and turned potentially skilled workers into low-level computer technologies. Computers have facilitated the work of scholars, but also turned them into typists; yet one hears hardly a complaint. They have turned the simple act of buying a plane ticket into an endless manipulation (控制) , but we welcome the so-called convenience. They have encouraged new forms of crime and fraud(欺诈) , but we describe them with grudging admiration. They have allowed new types of evil weaponry. But we call them "smart bombs". Perhaps the most important, information technologies have extended the power of the mass media, creating unusual possibilities for political manipulation reducing accountability (有责任,有义务 ), and changing the nature of political life. It is true that there are critiques(批评) of information technologies from those professionally concerned about their problematic(有问题的) legal, social and political implications. There is a near total absence, however, of organized public concern about technologies with profound and problematic implications.
