2.3 Development of computer network
technology
Computer network technology has developed for many years, and
its theory becomes more complete. Because of the construction of
hardware infrastructure, the network bandwidth has been
improved to a large extent. However, the actual investigation
found that the development of modern information industry in
China is poorer, affected by the special historical factors.
Compared with Japan and South Korea and some western
developed countries, Chinese network bandwidth is so backward
that it has not even reached the world average. In this context, the
state has introduced a lot of pertinent policy, which increased the
investment of the network infrastructure and greatly improved the
level of network in China. According to the improvement of
network bandwidth, it shows that the network speed of
transmission has achieved the double growth in just a few short
years. The improvement of network bandwidth has promoted the
development of network technology. At present, the network
infrastructure has mainly developed into fiber- optical. Transport
protocols are also constantly improved, with great progress
achieved in the transmission speed, safety and stability, etc.
