Three Common network protocols: NetBEUI, IPX/SPX, and TCP/IP

Q: What are the NetBEUI and IPX/SPX TCP/IP protocols ?? In particular, the first two are sometimes installed, and sometimes they are not installed. Why ?? What are their differences and uniqueness? When must I install it?

A: A lot of netizens asked this question. I have consulted and integrated the relevant information here to give you a detailed explanation.

The network Protocol is a special software and the most basic mechanism for a computer network to implement its functions. Network protocols are essentially rules that must be followed by a variety of hardware and software. Network protocols are not a set of independent software. They are integrated into all other software systems. Therefore, protocols are ubiquitous in the network. The network protocol covers all layers of the OSI communication model. There are thousands of protocols from familiar TCP/IP, HTTP, and FTP protocols to OSPF and IGP. For common users, they do not need to care too much about the underlying communication protocols, but only need to understand their communication principles. In actual management, underlying communication protocols generally work automatically without manual intervention. However, for a layer-3 or above Protocol, manual intervention is often required. For example, the TCP/IP protocol requires manual configuration to work properly.

Three common communication protocols are TCP/IP, NetBEUI, and IPX/SPX. The TCP/IP protocol is undoubtedly the most important of the three protocols. As the basic protocol of the Internet, it is impossible to access the Internet without it, any Internet-related operations are inseparable from the TCP/IP protocol. However, the TCP/IP protocol is also the most troublesome configuration among the three protocols. It is better to use a single machine to access the Internet. However, if you access the Internet through a LAN, you must set the IP address, gateway, and subnet mask in detail, DNS server and other parameters.

Although TCP/IP is currently the most popular network protocol, the communication efficiency of TCP/IP protocol in LAN is not high. When using it to browse computers in "Network neighbors, browsing failures often occur. The NetBEUI protocol is installed to solve this problem.

NetBEUI is the NetBios Enhanced User Interface, or the NetBios Enhanced User Interface. It is an enhanced version of the NetBIOS protocol and has been used by many operating systems, such as Windows for Workgroup, Windows 9x series, and Windows NT. The NETBEUI protocol is useful in many cases. It is the default protocol of the operating system before Windows 98. The NetBEUI protocol is a short and concise broadcast protocol with high communication efficiency. It does not need to be set after installation. It is especially suitable for transmitting data in "Network neighbors. In addition to the TCP/IP protocol, it is recommended that the NetBEUI protocol be installed on computers in Small Lan. Note that if you want to add a Windows 98 machine with only TCP/IP protocol to the WINNT domain, you must also install NetBEUI protocol.

The IPX/SPX protocol was originally developed by Novell for the NetWare network, but it is also very common now-most online games support IPX/SPX protocols, such as Starcraft, counter-terrorism elites. Although these games can also be online through the TCP/IP protocol, it is clear that it is easier to use the IPX/SPX protocol because no setup is required. In addition, the IPX/SPX protocol does not seem to be very useful in the local area network. If it is determined that it is not in the local area network, then this protocol is dispensable.
