network service protocol

NetBIOS protocolNote: NetWork Basic Input/Output System (Basic NetWork Input/Output System) is a small LAN developed by IBM and mainly used for dozens of computers. The NetBIOS protocol is an application programming interface (API) that can be used by a program on the LAN. It provides a unified command set for the program to request low-level services, it serves

Computer network refers to the different geographic locations of multiple computers with independent functions and their external devices, through the communication lines connected together,Under the management and coordination of network operating system, network management software and network communication

Network and network protocol 1: Network 1. Basic concepts of communication two objects transmit information through a certain medium. 2. Signals and communication signals: convert data and signals into electronic signals, it is transmitted in the form of electromagnetic waves. Broadband: signals can be seen as the synt

This article we continue through the network analysis expert analysis system to help better solve and deal with the actual problems of the network, through its own powerful analysis system quickly locate the fault, in the first time to solve the problem. One, the more effort to monitor MSN: Perhaps monitoring MSN Chat will violate the privacy of employees, but in the case of a business ban chat through mo

introduction, security is better. For domain name server DNS, different 3G technologies can be shared. Its settings are also divided into two categories: set at the national DNS level, and by national root DNS and provincial level DNS two. For security reasons, DNS Cheng settings. To simplify the network structure and facilitate management operations, DNS is best set up in the core node. Construction of 1.2 bearing

TCP: TCP/IP creates a connection through three handshakes. Three packets in this process are SYN, SYN/ack, and ack. The first step is to find the first SYN Packet sent from the PC to the network server, which indicates the start of TCP three-way handshake. If you cannot find the first Syn packet, selectEdit-> Find PacketMenu options. Select display filter and enter TCP. Flags. A flag list is displayed for selection. Select the appropriate flag, TCP. F

Before I begin, I'd like to describe what this so-called communication program is all about. The communication program is similar to a weak version of QQ, login needs to register, after successful login, you can achieve instant communication, group chat, private chat, but also can be transmitted documents. Let's get to the last picture Server side: Client Login: Client main interface: The so-called real-time communication program, that is, the use of TCP and UDP transmission

. and using ATM (asychronous Transfer Mode. Asynchronous transfer Mode) for WAN, CDPD (Cellular digital Packet data, wireless cellular number packet) network, and very many other networks. Although there are very big differences between these network technologies, IP treats them equally. Except that they are able to forward the packet without any regard to it, no matter what. Such a mechanism implies very d

The data link layer provides reliable transmission on unreliable physical media. The functions

I. Overview Review the video surveillance market, the monitoring platform system used by the signaling control protocol is not unified, resulting in the interconnection of the technical threshold. This is a bit similar to the 80 's China's switch market eight system of the situation. These reasons hinder the network era of large-scale carrier-level video surveillance, remote access, centralized management n
