NETWORK TECHNOLOGIES AND COMPUTER COMMUNICATIONS

Currently, computer networks are developing rapidly. It is difficult to imagine

any organization or institution without computer networks. The Internet, a global international

computer network that emerged at the end of the 20th century, is proof of this. This network is

becoming one of the electronic forms of information that many people receive daily from

newspapers, journals, and books. Therefore, using and studying the structure of computer

networks and obtaining information from them is of great importance

当前，计算机网络（Computer Network）正处于高速发展阶段。如今，任何组织或机构脱离计算机网络都难以维持正常运转。诞生于20世纪末的全球互联计算机网络——互联网，正是这一趋势的有力佐证。现如今，互联网已成为众多民众每日获取信息的重要电子媒介之一，其地位可与报纸、期刊、书籍等传统信息载体比肩。因此，研究并利用计算机网络的架构，并从中获取有效信息，具备极高的现实意义与学术价值。
