What is network technology?
We connect multiple computer systems with different geographical location and independent functions through communication equipment and lines, and use the full function network software to realize the large system of network resource sharing, called computer network. In other words, computer networks can connect several computer systems into simple networks with communication lines, realize information collection, distribution, transmission and processing, and can also connect thousands of computer systems and thousands of kilometers or even tens of thousands of kilometers of communication lines into national or global computer networks. According to the different areas covered by the network, the computer network can be divided into LAN, Wan, man and Internet. From the current situation, it technology management posts of enterprises are generally set up as information director and director of enterprises; The engineering technical posts are set up as network engineer, software engineer and database engineer; The operation and maintenance post is set as database administrator, system administrator, network administrator, equipment administrator, etc; The operation post is set as official document operator, CAD Designer, web page producer, multimedia producer, etc. Compared with software technicians, network technicians have a wider range of work, more complex knowledge system and higher professional skills requirements. At present, network engineers have become a huge bottleneck in the implementation of domestic informatization.
