Introduction to
LAN/WAN Internetworking
2-Day Session

From the basic use of Local Area Networks (LANs), organizations have blazed their way through changes that are occurring in the industry. Large staffs to manage network services have become a thing of the past. Now the true Information Manager must develop strategies that will serve the needs of the organization on smaller computers, allow for a resilient and flexible network connectivity arrangement, and be prepared to adjust quickly as the needs of the organization change. Tomorrow will present a new set of challenges, that being the connectivity from anywhere within the organization to any service that is available, in a timely, and accurate manner. Synchronizing the data sets with the databases is critical. Transactional processing on one computer must be updated immediately on another to keep the data current throughout the network. Real time access is required now, so the network must be supportive of native throughput on a local, a regional or a national basis. This is the livelihood of the company's revenue streams or the competitive edge that separates our products and services from our competitors.
