demand for a large amount of data, DVD forum in the Development of DVD-R specifications, take the following four points as the basis:1. DVD-R is a new type of record system with the same CD-R.
2. After recording the DVD-R optical disc, It is interchangeable with 100% of the general DVD dial-on.
3. Supports multi session recording
4. DVD-R optical discs have extremely high cost/performance values.
DVD-R is led by pioneer company development can write a DVD specification, the earliest development

Machine learning is accelerating the pace of progress, it is time to explore this issue. Ai can really protect our systems in the future against cyber attacks.
Today, an increasing number of cyber attackers are launching cyber attacks through automated technology, while the attacking enterprise or organization is still using manpower to summarize internal security findings, and then compare them with external threat information. Intrusion detection systems deployed in this traditional way often
The advantage of cable network monitoring is low transmission cost, large network bandwidth and good transmission effect, but it can't realize the monitoring demand of mobile industry. 3G Wireless monitoring advantage is to realize the mobile audio and video monitoring, easy to temporary monitoring, but high transmission costs, low network bandwidth, transmission effects are affected by a variety of factors.
In the field of networked monitoring, cable network monitoring accounted for 10% of 90%

However, while facilitating sharing, the bandwidth usage that comes along with it is also a headache. Therefore, the distributed computing industry association (dcia) proposed the "P4P" network protocol concept, and Verizon's recent experiments also prove that this P2P network upgrade can indeed greatly increase the download speed, and significantly
