Key knowledge of computer network A comparison of circuit switching, message exchange and packet switching 1. Circuit Exchange Public telephone Network (PSTN) and mobile network (including GSM and CDMA network) are used in circuit switching technology, its basic feature is the use of connection-oriented approach, befor
This article is from the "Knowledge Forest" In the previous example, the communication between the container and the container is done through the IP address in the network, which is obviously unreasonable, because the IP address may change when the container is started, and it is also more difficult to remember. The solution to this problem is to use a network alias, the container is allowed to be alias on
"Matlab Neural network Programming" Chemical Industry Press book notesFourth. Forward-type neural network 4.2 linear neural network This article is "MATLAB Neural network Programming" book reading notes, which involves the source code, formulas, principles are from this book, if there is no understanding of the place p
As a common Internet user, sudden network faults have a headache. They not only affect our use, but also cause unnecessary losses, therefore, simply understanding the basic network test commands is also a good thing for us, saving time and improving work efficiency. Today, I would like to list some of the most common network failure test commands for your referen
Faults are inevitable during network management and O M. If an administrator attempts to build a zero-fault network, it will be futile. There are too many randomness and contingency factors in network faults, not to mention human factors. Therefore, what administrators need to do is to master the network troubleshooti
[Network layer] network layer Overview 1. What are the differences between the two service virtual circuits and the datagram service provided by the network layer? Virtual circuit datagram connection must be established. Do not use the destination site address. It is only used during connection establishment, each group uses a short virtual circuit number. Each g
Network programming refers to writing programs that communicate with other computers. Java has encapsulated the things that a network program needs into different classes. Whenever you create objects of these classes, use the appropriate method.1. LAN and InternetTo enable communication between two computers, you must connect two computers with one network line
Overlay NetworkOverlay network is a new data format that encapsulates two beginning text over an IP message without altering the existing network infrastructure, through some kind of protocol communication.This will not only take full advantage of the mature IP routing protocol process data distribution, but also in the overlay technology, the use of extended isolated identity bits, can break the VLAN 4000
Many win7 system users create LANs to share resources. When we visit, generally through the sharing of the way to the local area network computer access, operation, storage. If we use the "Map Network Drive", we can access it easily. "Map Network Drive" is actually the local area network of the pastoral directory map o
The biggest problem with full-attached neural networks (Fully connected neural network) is that there are too many parameters for the full-connection layer. In addition to slowing down the calculation, it is easy to cause overfitting problems. Therefore, a more reasonable neural network structure is needed to effectively reduce the number of parameters in the neural net
In the rapid development of the Internet today, the network has become an indispensable part of our daily life. When you are surfing the Internet at the same time, your computer will inevitably have such a network failure, on the network, how to find these network failures? It's really a difficult problem for beginners
Host-onlyBridge connectionNatVMware Virtual machine Three ways and principles of networkingOne, brigde--bridge: Default use VMnet01. Principle:Bridge Bridges "is a host, the machine has two network cards, respectively, in two LAN, while on the" bridge ", running the program, so that all packets in LAN a intact flow into B, and vice versa. In this way, the LAN A and B are seamlessly connected at the link layer, in the bridge, the VMware
1. OverviewClos from the traditional circuit exchange concept, the concept of the age is too long, in the current data communication network, the connotation has changed. This article mainly discusses is actually endowed with originally slightly has the difference connotation.Clos architecture itself is relatively broad, with equipment-level Clos, as well as network-level Clos.Network-level ClosThis concept

In the article "The essential characteristic of the network advertisement", it concludes the four essential characteristics of the network advertisement, and the analysis of the essential characteristics of the network advertisement lays the foundation for understanding the value of the network advertisement deeply.

For the small and medium-sized network administrators, the most headache is how to effectively manage the enterprise network, so that the enterprise network operation efficiency is higher. Usually we in the network management is always sandwiched in the middle, we must focus on external
Author: techrepublic.com.com Mike Mullins explains why you should change the network address of the network deployment. The following are some considerations. If the network you manage has enough IP addresses to cover hosts and servers, you may not need to configure network address translation (NAT ). Nat allows a sing
1. Read attack Read attacks mainly include all attacks related to information retrieval from victims. Such attacks scan ports and vulnerabilities within the IP address range of the organizational structure, and finally obtain information from vulnerable hosts. 1. Reconnaissance recon Attacks: Reconnaissance recon attacks: these attacks are designed to enable attackers to obtain more information about victims. They can use active and passive methods, in almost all cases, successful reconnaiss
