Introduction To Communication Protocols

The following article is mainly about wireless encryption is commonly used in wireless network encryption protocol, in the actual operation of the widely used wireless network encryption protocol mainly includes WEP encryption protocol and WPA encryption protocol two. The widely used wireless network encryption protocol mainly includes WEP encryption protocol and WPA encryption protocol. WEP protocol is also called Wired Equivalent encryption protocol, this kind of wireless communication protocol is often those who are eager to produce and sell wireless equipment in a relatively short period of time to put together the informal wireless encryption communication standards, from the current view of this wireless network encryption protocol There are quite a lot of security ...

The scalability of the system is the main reason for promoting the development of NoSQL movement, including distributed system coordination, failover, resource management and many other features. That makes NoSQL sound like a big basket that can be stuffed with anything. Although the NoSQL movement does not bring fundamental technological changes to distributed data processing, it still leads to extensive research and practice on protocols and algorithms. It is through these attempts to gradually summarize some effective database construction methods. In this article, I will focus on the NoSQL database distributed special ...

Abstract: We see that today's Internet products have been difficult to set a threshold from the functional level, the need to rely more on the user experience, cloud services, data services, strong architecture and communication protocols as the support, coupled with the emergence of a growing number of entrepreneurial companies, which we see today's Internet products are very difficult to simply from the "function Level to establish a threshold, the need to rely more on the user experience, cloud services, data services, strong architecture and communication protocols as a support, coupled with the emergence of a growing number of entrepreneurial companies, which makes this kind of talent needs greatly increased, but all along, enterprises ...

"Editor's note" Mature, universal let Hadoop won large data players love, even before the advent of yarn, in the flow-processing framework, the many institutions are still widely used in the offline processing. Using Mesos,mapreduce for new life, yarn provides a better resource manager, allowing the storm stream-processing framework to run on the Hadoop cluster, but don't forget that Hadoop has a far more mature community than Mesos. From the rise to the decline and the rise, the elephant carrying large data has been more ...
