Compared to building intercom, Internet telephony can be said to have been in our lives for a short time. Generally speaking, network telephony refers to IP as the network layer protocol of the computer network voice communication system, it uses the technology collectively referred to as VoIP (Voiceover IP), that is, the use of the

a summary of neural networks found that now every day to see things have a new understanding, but also to the knowledge of the past. Before listening to some of Zhang Yuhong's lessons, today I went to see some of his in-depth study series in the cloud-dwelling community, it introduces the development of neural network history, the teacher is very humorous, theory a lot, no matter what anyway can say a 123, but feel the article sometimes too broad, in

Most enterprises pay attention to improve the security of the border of enterprise network, but do not mention how much they invest in this aspect, but the core intranet of most enterprise network is still very fragile. The following is a few strategies to address the security challenges of the enterprise intranet. These strategies are the defense strategy of the Intranet, and also a strategy to improve the

Differences between three network connections in VMware and three network connections in vmware 1. Overview After the virtual machine is installed, two virtual NICs, VMnet1 and VMnet8, are installed by default. VMnet1 is the host Nic and is used to connect to the network using the host method. VMnet8 is the NAT Nic, they are used to connect networks in NAT mode a

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
