Nowadays, DOS has become a thing of the antique class and has been completely abandoned by the Windows operating system. The existence of real-mode DoS cannot be found in the latest Win2000/XP, instead of the command line mode. Is dos useless at all? Do I have to understand the doscommand? In fact, many command line commands are provided in the 98/2000/XP system. These commands are very similar to those in DOS. If we use these commands well, we can get twice the result with half the effort in ou

Three major network security categories: Microsoft's network access protection and Microsoft's network access protection. How to recover it becomes the problem of Microsoft's network access protection, the steps of network security construction are explained in depth during

The rapid development of network technology, the scale of the network has been expanding, so that more and more companies and organizations gradually began to experience a "growing pains." The network becomes the fundamental communication inside and outside the enterprise, in the continuous expansion of network scale a

As a powerful hacker attack method, DDoS is a kind of special denial of service attack. As a distributed, collaborative, large-scale attack, it often locks victim targets on large Internet sites, such as commercial companies, search engines, or government department sites. Because of the bad nature of DDoS attacks (often through the use of a group of controlled network terminals to a common port to launch a shock, the rapid and difficult to prevent, w

1. From level two IP address to level three IP address:* * Level Two IP address design unreasonable:The utilization of ①IP address space is sometimes very low;② assigns a network number to each physical network, which causes the routing table to become too large and thus causes the network performance to become worse;③ level Two IP address is not flexible;2. subn

With the rapid development of computer network technology, network security issues have become increasingly prominent in the face of various users. According to the data obtained by the author, nearly 20% of users on the Internet have suffered from hackers. Although hackers are so rampant, the network security problem has not yet attracted enough attention. More

Physical connections must be established between t

There are countless articles on the wireless network stability settings introduced on the network. Through these articles, we can also learn about the configuration process. So the security and stability of wireless networks. Let's make a deep analysis. We must be familiar with the use of wireless networks, but we often encounter unstable network conditions durin

There are still many things worth learning about integrated network cabling. Here I will mainly explain to you how network cabling works in integrated network cabling, this includes network cable Testing, one-by-one enabling of computers, "Hot swapping" of Network cables, an

We do not know much about wireless network settings. How can we enhance the security of wireless networks and improve the stability of network signals? The following is a detailed introduction. Although the implementation of wireless networks has been quite high at the beginning of the design, wireless network configuration is not a simple task for more new users

China's wireless access network is still widely used, and it is also very important to optimize the network. So I studied the GSM network optimization problem of the Wireless Access Network, I would like to share it with you here and hope it will be useful to you. With the development of the mobile communication indust

Testing tools are the means to achieve automated testing. The rational use of testing tools can not only improve the network diagnostic capability, but also facilitate network management. Generally, broadly speaking, network testing tools can be divided into physical cable tester, network operation simulation tool, pro

Enterprises are becoming more and more demanding on the network, in order to ensure the high availability of the network, sometimes want to provide equipment, modules and link redundancy in the network. However, in the two-tier network, redundant links may lead to switching loops, allowing broadcast packets to cycle e

Today's two network structures are the latest in the industry for image processing problems proposed by the latest structure, the main solution is the Super deep network in training optimization problems encountered. To tell the truth, both models are not mathematically complex in themselves, but it does have a very good effect in combat (the deep residual network
