Three main network transmission protocols

Network transmission protocols, as the name implies, are the specifications and standards used during network transmission. We are familiar with the TCP/IP protocol. However, there are not only transmission protocols in the Internet, but also network transmission protocols in other usage specifications. Now let's take a look at this aspect.

Network protocols include the Internet. For example, communication between people must follow certain rules, and mutual communication between computers must comply with certain rules. These rules are called network protocols.

A computer can communicate with other computers on the network only when it complies with the network protocol. Network protocols are generally divided into several layers to complete their own functions. Both parties can communicate with each other only at the same level.

Common protocols include TCP/IP, IPX/SPX, and NetBEUI. IPX/SPX is usually used in the LAN .. If you access the Internet, you must add the TCP/IP protocol to the network protocol.

Network Transmission Protocol 1: TCP/IP

TCP/IP is short for transmission Control Protocol/Internet Protocol) it is a network communication protocol that regulates all communication devices on the network, especially the data exchange formats and transmission methods between one host and another. TCP/IP is a basic INTERNET protocol and a standard method for packaging and addressing computer data.

In data transmission, two envelopes can be visually resolved. The TCP/IP and IP are like an envelope. The information to be transmitted is divided into several segments, each of which is inserted into a TCP envelope, record the information of the segment number on the envelope, insert the TCP envelope into the IP address envelope, and send the information to the Internet. On the receiving end, a TCP Software Package collects envelopes, extracts data, restores the data in the order before sending, and verifies the data. If an error is found, TCP requests to resend the data. Therefore, TCP/IP can transmit data almost without errors on the INTERNET. For ordinary users, you do not need to understand the entire structure of the network protocol. You only need to know the IP address format to communicate with networks around the world.

Network Transmission Protocol 2: IPX/SPX

IPX/SPX is XEROX's Network SystemXNS Protocol based on XEROX, while SPX is XEROX's spox quenced Packet Protocol based on XEROX, they are a high-speed protocol developed by novell for LAN.

A major difference between it and TCP/IP is that it does not use an IP address, but uses the NIC physical address (MAC) address. In actual use, it basically does not need any settings, and can be used after installation. Since it played a huge role in the early days of network popularity, it has been supported by many vendors, including microsoft, and many software and hardware have now supported this protocol.

Network Transmission Protocol 3: NetBEUI

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.

In short, 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 NetBEUI be installed on LAN computers. 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.

WAPI is the abbreviation of WLAN Authentication and Privacy Infrastructure. Like infrared, Bluetooth, GPRS, and CDMA 1X, it is a type of wireless transmission protocol, except that it is a transmission protocol in a WLAN, it is similar to the current 802.11B transmission protocol.
