are continuing to increase network throughput. One strategy is to improve
speeds on existing networks through new forms of compression or presentation.
However, the need to reduce file size to speed delivery may be a limited-term
concern as broad bandwidth information pipelines and wireless high speed
data transfer capabilities are developed in the next 5-10 years to support
research, electronic commerce, and entertainment. The increasing deployment
of cable modem and DSL services to residences will ease bandwidth concerns
at the user's end. The potential of digital television, in particular
High Definition Television (HDTV), to provide new and different kinds
of information to a broad range of usersincluding access to digitized
cultural resourcesis tantalizing. Current US Federal Communications
Comission (FCC) rules require all analog broadcasts to be phased out by
the end of 2006. Beginning with Internet 2, the U.S. government is funding
efforts to build the Next Generation Internet (NGI) to link research labs
and universities to high-speed networks that are 100 to 1,000 times faster
than the current Internet. Designed to handle high volumes of information,
the NGI will make access to digital image files easy and high quality
audio and moving image transfer practical.
Most of the requirements for a network server have already been touched
upon. Such machines are very resource hungry, especially if heavily used.
Keeping a network server optimally tuned requires a skilled systems administrator.
Perhaps the best advice is not to skimp on personnel for managing networks
