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

The goal of smart-highway technology is to make traffic systems work at optimum efficiency by treating the road and the vehicles traveling on them as an integral transportation system. Proponents of the advanced technology say electronic detection systems, closed-circuit television, radio-communication, ramp metering variable message signing, and other smart-highway technology can now be used at a reasonable cost to improve communication between drivers and the people who monitor traffic②.
Pathfinder, a Santa Monica, California-based smart-highway project in which a 14-mile stretch of the Santa Monica Freeway, making up what is called a "smart corridor," is being instrumented with buried loops in the pavement. Closed-circuit television cameras survey the flow of traffic; while communication linked to property equipped automobiles advise motorists of the least congested routes or detours.
Not all traffic experts, however, look to smart-highway technology as the ultimate solution to traffic gridlock. Some say the high-tech approach is limited and can only offer temporary solutions to a serious problem.
"Electronics on the highway addresses just one aspects of the problem: how to regulate traffic more efficiently," explains Michael Renner, senior researcher at the world-watch Institute. "It does not deal with the central problem of too many cars for roads that cannot be built fast enough. It sends people the wrong message. They start thinking 'yes, there used to be a traffic congestion problem, but that's been solved now because we have advanced high-tech system in place." Larson agrees and adds, "Smart highway is just one of the tools that we use to deal with our traffic problems. It is not the solution itself, just pan of package. There are different strategies."
Other traffic problem-solving options being studied and experimented with include car-pooling, rapid mass-transit systems, staggered or flexible work hours and road pricing, a system whereby motorists pay a certain amount for the time they use a highway③.
It seems that we need a new, major thrust to deal with the traffic problems of the next 20 years. There has to be a big change and a long way to go.
