Network Agreement is a special software that is the most basic mechanism for computer networks. The nature of the network protocol is rules, namely the common procedures that the various hardware and software must follow. The network protocol is not a separate software that is integrated into all other software systems, so it can be said that the agreement is omnipotent in the network. Network protocols all over the OSI communication model, from our very familiar TCP / IP, HTTP, FTP protocol, to OSPF, IGP, etc., there are thousands of protocols. For ordinary users, there is no need to care too much underlying communication protocol, just understand its communication principle. In actual management, the underlying communication protocol will generally work automatically and do not require manual intervention. However, for the third level of protocols, artificial intervention is often required, such as the TCP / IP protocol, it is necessary to manually configure it to work.
The three communication protocols commonly used by the local area network are TCP / IP protocols, NetBeui protocols, and IPX / SPX protocols. The TCP / IP protocol is undoubtedly the most important one in the three major agreements. As the foundation agreement of the Internet, it is impossible to go online at all, any and the Internet is inseparable from the TCP / IP protocol. However, TCP / IP protocol is also the most troublesome of these three major agreements. It is also good to access the Internet. If you access the Internet, you must set the parameters such as IP address, gateway, subnet mask, DNS server.
TCP / IP Although it is currently the most popular network protocol, the communication efficiency in the TCP / IP protocol is not high in the local area network, and it often does not normally browse when browsing the computer in "online neighbor". The installation of the NetBeui protocol will solve this problem. NetBEUI is Netbios Enhanced User Interface, or NetBIOS enhances user interface. It is the enhanced version of the NetBIOS protocol, which has been used by many * as a system, such as Windows for Workgroup, Win 9x Series, Windows NT, etc. The NetBeui protocol is useful in many cases, which is the default protocol of the system before Windows98. In short, the NetBeui protocol is a broadcast protocol for short and high communication efficiency. It does not need to be set after installation, especially suitable for transmitting data in "network neighbors". Therefore, it is recommended that the LAN's computer is best equally on the NetBeui protocol in addition to the TCP / IP protocol. In addition, you should pay attention to if a Windows98 machine that is installed with a TCP / IP protocol is to be added to the WinNT domain, but also the NetBeui protocol is also installed.
The IPX / SPX protocol is originally a protocol for Novell's specialized in NetWare networks, but now it is also very common - most of the games that can be online support IPX / SPX protocol, such as StarCraft, Counter Strike, etc. Although these games can be online through the TCP / IP protocol, it is clearly more expensive through the IPX / SPX protocol, as it does not require any settings at all. In addition, the use of the IPX / SPX protocol in the local area network does not seem to be large, and if it is determined to play games online, then this protocol can be available.
