Arrange an informational interview with a technical support specialist. Local computer repair shops that offer technical support service might be a good place to contact. Also contact major corporations and software firms directly.

Work and play on computers as much as possible; many computer professionals became computer hobbyists at a very young age. Surf the Internet and seek out the assistance of an online support specialist if assistance is needed with a video game or other computer problem. Read computer magazines and join school or community computer clubs.

Another good way to explore this field is through a computer technology course at a local technical/vocational school. This would give hands-on exposure to typical technical support training. In addition, if you experience problems with your own hardware or software, call technical support; pay careful attention to how the support specialist handles the call and ask as many questions as the specialist has time to answer.

Most companies rely on computers for a variety of business functions: daily operations, such as employee time clocks; monthly projects, such as payroll and sales accounting; and major re-engineering of fundamental business procedures, such as form automation in government agencies, insurance companies, and banks. As a result, it has become increasingly critical that computers function properly all the time. Computer downtime can be extremely expensive, in terms of work left undone and sales not made, for example. When employees experience problems with their computer system, they call technical support for help. Technical support specialists investigate and resolve problems in computer functioning.

Technical support consists of three distinct areas, although these distinctions vary greatly with the nature, size, and scope of the company. The two most prevalent areas are user support and technical support. Most technical support specialists perform some combination of the tasks explained below.

The jobs of technical support specialists vary according to whom they assist and what they fix. Some specialists help private users exclusively; others are on call to a major corporate buyer. Some work with computer hardware and software, while others help with printer, modem, and fax problems. User support specialists, also known as help desk specialists, work directly with users themselves, who call when they experience problems. The support specialist listens carefully to the user's explanation of the precise nature of the problem and the commands entered that seem to have caused it. Some companies have developed complex software that allows the support specialist to enter a description of the problem and wait for the computer to provide suggestions about what the user should do.

The initial goal is to isolate the source of the problem. If user error is the culprit, the technical support specialist explains procedures related to the program in question, whether it is a graphics, database, word processing, or printing program. If the problem is in the hardware or software, the specialist asks the user to enter certain commands in order to see if the computer makes the appropriate response. If it does not, the support specialist is closer to isolating the cause. The support specialist consults supervisors, programmers, and others in order to outline the cause and possible solutions.

Some technical support specialists conduct live chats online with customers who are having difficulty using a company’s Web site, accessing content, or making an online purchase. They also interact with online customers via instant messaging software, e-mail, or telephone.  

Some technical support specialists who work for computer companies are mainly involved with solving problems whose cause has been determined to lie in the computer system's operating system, hardware, or software. They make exhaustive use of resources, such as colleagues or books, and try to solve the problem through a variety of methods, including program modifications and the replacement of certain hardware or software.

Technical support specialists employed in the information systems departments of large corporations do this kind of troubleshooting as well. They also oversee the daily operations of the various computer systems, Local Area Networks, Wide Area Networks, and other systems in the company. Sometimes they compare the system's work capacity to the actual daily workload in order to determine if upgrades are needed. In addition, they might help out other computer professionals in the company with modifying commercial software for their company's particular needs.

All technical support work must be well documented. Support specialists write detailed technical reports on every problem they work on. They try to tie together different problems on the same software, so programmers can make adjustments that address all of the issues. Record keeping is crucial because designers, programmers, and engineers use technical support reports to revise current products and improve future ones. Some support specialists help write training manuals. They are often required to read trade magazines and company newsletters in order to keep up to date on their products and the field in general.
