protocols. common protocols include: TCP/IP protocol, IPX/SPX protocol, and NetBEUI protocol. IPX/SPX is usually used in LAN, you must add the TCP/IP protocol to the network protocol ｡ TCP/IP is short for "transmission Control Protocol/Internet Protocol ｡ TCP/IP is a network communication protocol, which regulates all communication devices on the network, in particular, the data exchange format and transmi

Open System Interconnection Reference Model is widely used, it describes the network structure at seven layers: physical layer, data link layer, network layer, transport layer, dialogue layer, presentation layer, and application layer. It should be noted that the advantages and disadvantages of the network architecture will directly affect the performance of the bus, interfaces and networks. The key elements of the network architecture are protocols and topologies. Currently, the most common ne

Valid values of pip (pipes), tcp (TCP/IP), and spx (ipx/spx) include seipcpip, setlitcp, sescotcp, setlispx, the last three can be used as servers, such as setlitcp (SE, Socket, TCP/IP)The hostname field is the host name. If the TCP/IP protocol is used, the hostname must appear in/etc/hosts. The host name can be a local host (for the server) it can also be another ser

Classification of computer network protocols Network protocols are a special software and the most basic mechanism for computer networks to implement their functions. network protocols are essentially rules that must be followed by a variety of hardware and software. however,

D 3: In general, the above box should include: · IPX/SPX compatible communication protocols · NetBEUI · TCP/IP The three communication protocols should be added here. if you only need the "interconnectivity on the network" requirement, you only need "NetBEUI" and "TCP/IP! Otherwise, the online speed of the network may be slow! For more information about why you do no

). That is, with the combined use of many communication protocols, the layer-7 model of the network can work properly to ensure the normal network communication. 1. Classification of computer network communication protocols Network protocols are a special software and the most basic mechanism for computer networks to implement their functions. Network protocols are essentially rules that must be followed by a variety of hardware and software. However, the network protocol is not a separate set

1. Common programming models are used by the OSI and TCP/IP models.2. The main concepts in the network: protocols, interfaces and services.Protocol refers to the rules that the same layer needs to interact on different hosts, often with Tcp/ip,ipx/spx,netbeui and so on. LAN is mainly ipx/spx, Internet -based is the use of TCP/IP.An interface is a convention that interacts between different adjacent layers o

Possible causes: (1) Whether the nwlink IPX/SPX/NetBIOS compatible transport protocol is installed. (2) Enable the Guest account: Right-click my computer \ management \ user to have a guest, and double-click it to remove the check box before "Account Disabled. (3) Unify the working group names of each computer: Right-click my computer \ properties \ computer name, view the name of the LAN working group displayed on this tab, and add all compu

If the print server can be found, it indicates that the basic conditions for the shared printer are met. If an error occurs, the problem should be solved first.Solution: after confirming that the LAN working group name is consistent, go to the "local connection" attribute window and click "install" to add the

The function Netif_rx () (net/core/dev.c 1214 lines) passed by the core layer of the network interface receives the data sent from the upper layers, which of course sends the packets to the top. All protocol families need to receive data, TCP/IP protocol and ARP protocol, spx/ipx IPX protocol, AppleTalk DDP and AARP protocol, etc. all need to receive data directly from the core layer of the network interface. How does the core layer of the

The samba client is made up of CIFS server,active director and S and vices for UNIX. The Smaba listens on the 137/udp,138/udp,139/tcp,445/tcp port. about NetBIOSNetBIOS is the abbreviation for the network basic input and output system (English: NET basic input/output systems),

Solutions for WinXP systems that cannot share printers Phenomenon One: Network Neighborhood cannot browse normally To share a printer in Windows XP, the first thing to do is not to install the network printer directly on the workstation, but to first look at the View workgroup computer item in My Network Places to see if the computer that has the printer installed (the print server) is available. If you can find a print server, the basic conditions for sharing a printer are available, and if

In Windows XP, there are a number of reasons why you can't share a printer, and at this point, are you at your wits end? To solve the problem, let's take a look at the problems that are most likely to occur when sharing printers in Windows XP and how to fix them. 　　 Phenomenon One: Network Neighborhood cannot browse normally To share a printer in Windows XP, the first thing to do is not to install the network printer directly on the workstation, but to first look at the View workgroup compute

Protocol technology (OPT), the combination of protocols enables different types of workstations to communicate with public servers. This technology to meet the vast number of users in different types of networks to achieve mutual communication needs, to achieve a variety of different networks of seamless communication, that is, a variety of network protocols are tightly connected, you can easily with a variety of small machines, mainframe connection communication. NetWare can not use a dedicate

　　"Printer" is the most common partner in our work, and its stable and efficient operation, also determines whether our work is smooth. The user in the process of using the printer, the longest encountered difficulty is that the printer can not achieve the sharing of printing, which caused a certain amount of trouble to the user's work. Now, let's summarize some of the reasons why printers can't be shared. 　　Phenomenon One: Network Neighborhood cannot browse normally To share a printer in Wind

its role is the same as that of Mandarin. Ethernet (Ethernet), NetBEUI, ipx/spx, and TCP/IP protocols are commonly used depending on the network. Ethernet is the most common network low-level protocol in the general Line protocol, which is easy to install and inexpensive, while NetBEUI can be said to be a network protocol designed for small LAN. Installing the NetBEUI protocol is sufficient for small LANs that do not need to communicate with large ho
