John Halamka heads the information technology department at Harvard Medical School in the U.S. and also works as chief information officer for CareGroup Healthcare System, a private healthcare provider in the Boston area. A glitch in part of the hospital's computer network meant that traffic was being misrouted, creating a loop that was overwhelming the rest of the network. An auditor appointed to investigate the problem said that the hospital's network, used to deliver vital medical applications, was' a cutting-edge infrastructure, for 1996. All network staff should have a strong grounding in the fundamentals of the data network architecture, regardless of what technology is being used. The transmitter is normally a WiFi-compatible PC card in a laptop, and the receiver is a WiFi access device, which needs to be installed by the network manager, and acts as an access point to the corporate network. A virtual private network allows companies to provide secure access to workers who may not be connected to the network. INSETS: Case study;New network training.
