56, NT network card and Novell network card interoperability Hot Network Recently, a computer training center to establish a diskless NT teaching network, because the NT diskless Workstation network card has strict requirements: the number of cards (Adapter ID, that is, nod

NAT (Network address translation) is the process of converting an IP address in an IP packet header to another IP address. In practical application, NAT is mainly used to realize the function of private network accessing public network. This way, by using a small number of public IP addresses to represent more private IP addresses, will help to slow the depletion

Fault details:Network Communication is suddenly interrupted, some VLANs cannot access the Internet, and access to other VLANs is also interrupted. Ping packet testing is performed in the IDC, it is found that the ping packet from the central switch to the host

Wireless network Bridge maintenance work often requires experienced network administrators to coordinate, so the performance of the network often attracts many users of the eyeball, here to introduce you several aspects. How to improve the quality of network services, enhance competitiveness? I think we must strengthen

It is believed that most home users will prefer to use the Windows XP operating system, but the Windows 2000 operating system can still be seen in many office-used computers. In the recent network management maintenance, the author after a long time careful comparison and pondering, found in the Windows 2000 system for network card device replacement operation and Windows XP system has not exactly the same

introducehey! Does Socket programming make you frustrated. Is it hard to get useful information from man pages? You want to keep up with the times to do an Internet program, but frown on the structure of BIND () before you call Connect (). ...

When you cannot connect to the Internet, there are times when you need to do some experimentation to require that the host system and the virtual system interconnect. At this point, you can solve the demand by configuring the loopback network card. This article describes a brief step, starting with the Internet. First of all, the reason for this is to evade the research on VMware Network settings. When our

Differences between computer networks and distributed systems 1) Computer Networks (autonomous and interconnected) computer networks are connected by many computers, they can ask for help from each other. Three important features: computers connected to each other in computer networks are relatively independent. -- Each computer can provide servic

Most apps now need to get data from the Web. So access to the network is inevitable. But before we go back to the network, we should make a state judgment of the network first. In fact, before accessing the network we have to do some state judgment, corresponding to some state judgment to do processing, not directly us
