The world is operating in the age of information technology. To keep competitive in the global worldwide market, businesses and industries must rely on computer systems to process information, produce information, transmit information, exchange information and store information. The use of computer networking systems is dramatically increasing. Businesses and industries are installing and utilizing computer network systems, which stand alone or are integrated into already existing mainframe and midsize systems. Companies are also networking to the Internet and the worldwide web.
Many companies utilize both a network and a mainframe or midsize system.
The trend toward greater use of networking systems results in the need for personnel who possess a solid foundation in networking as well as a basic foundation in computer programming. A successful network technician must have the technical versatility to effectively communicate with all the types of information technology professionals.
