2 computer network technology overview
Computer network technology can be divided into several different types according to its network topology and connection range. The so-called topological structure means that computer networks can be divided into five basic types: tree type, bus type, ring type, star type and compound type according to the different connection methods between nodes in the network. According to the connection range, it can be roughly divided into three types: wide area network (WAN) and metropolitan area network (MAN) LAN (LAN). Network operating system has developed for half a century, and there are three main computer operating systems at present.
1)UNIX operating system. UNIX network operating system can be used for super-large computers and super-small computer-level RISC computers, and its characteristics are multi-user, multi-task, portability and interoperability.
2)NOVELL system. NOVELL system is the mainstream operating system in LAN market at present. It is developed on the basis of absorbing the multi-task and multi-user characteristics of UNIX operating system. It is an open network architecture and a highly connected system structure. As its main application, Netware adopts efficient system fault-tolerant technology, which makes the operating system more acceptable, which is one of the main reasons why the system can become the leading operating system in the world today.
3)Micosoft system. Micosoft operating system is the most powerful competitor of LAN market and NOVELL company in the current market.
