Use of the tcp ip protocol and other protocols in the Network

The tcp ip protocol is the basic transmission control protocol that must be used during network construction. How can we conduct modulation and analysis in this aspect during the networking process? First, we need to know some important protocols in the tcp ip protocol and other protocols to be used in the network construction.

Next, we will introduce the related protocols for network creation. About Gateway: provides the conversion between network protocols in communication, and applies to information exchange between hosts of different protocols ), domain Name resolution Server NDS: Domain Name System, that is, converting the URL you entered into a digital IP address) and NetBIOS.

Computer hardware is updated faster and cheaper. On campus, it is common for students to have computers. Imagine if these computers do not form a network, but are independent from each other, will they feel lonely and lonely? The answer is yes. Here, I will start with the most basic things and bring readers to build a network. This provides functions such as resource sharing, proxy surfing, and game battles.

Tcp ip protocol:

It is currently the most popular commercial protocol. Compared with OSI, it is the current industrial standard or "fact standard" proposed by Kahn in 1974.

It has four levels:

Application Layer

Transport Layer

Interconnection layer

Host-Network Layer

The tcp ip protocol is mainly used for Wide Area Networks and is also used in some LAN networks. For example, it can be used in windows 9x and netware networks. However, there is still a gap in functionality and speed, the original design goal of TCP/IP is different from that of ipx spx.

When setting the tcp ip protocol, the network mainly includes the IP address and subnet mask. Gateway: Provides the conversion between network protocols in communication, and is suitable for information exchange between hosts of different protocols ), domain Name resolution Server NDS: Domain Name System, that is, converting the URL you entered into a digital IP address) and NetBIOS.

Ipx spx protocol:

Now I want to explain this network protocol that is widely used. Ipx spx is a XEROX's Network SystemXNS Protocol based on XEROX, while SPX is a 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 physical address (MAC) Address of the NIC. Like the tcp ip protocol, it cannot be exactly the same as the OSI protocol. It only contains the transport layer and network layer of OSI. 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.

NetBIOS and NetBEUI:

Developed by microsoft and IBM, NetBIOS is a session-layer protocol that establishes connection sessions that allow applications on different computers to transmit over the network.

Network creation is designed only for session with other computers on the same network. In win9x & me, When you select "enable NetBIOS in ipx spx" in ipx spx, you can select "enable NetBIOS through TCP/IP" in TCP/IP Settings ".

NetBEUI is designed by IBM as a network product of the network transmission station. It is an extended version of NetBIOS and defines the volume type that is not defined by NetBIOS. It can transmit data on a single network of small and medium sizes. It can be directly installed and built in win9x & me.
