Switch from using WEBRTC to build front-end video chat room--Data channel ChapterIn two browsers, it is very complex to send messages for chat, games, or file transfers. Usually, we need to set up a server to forward the data, of course, the larger the size of the case, will be expanded into multiple data centers. In this case, there is a high latency and it is difficult to guarantee the privacy of the data.These issues can be addressed through the Rt

So here, our algorithm can be improved to maintain a K (10) Size of the small Gan, and then traverse 3 million of the query, respectively, and the root element to compare. The idea is consistent with the above algorithm, only the algorithm in the algorithm three, we use the smallest heap of this data structure instead of arrays, to find the target element of the time complexity of O (K) to O (LOGK).So, the use of heap data structure, algorithm three, t

This type of service is needed because different computer architectures use different data representations. For example, IBM hosts use EBCDIC e

security factors. For ordinary WEB applications, there are two things we can do to keep the data secure: HTTPS: Guarantees that the data is encrypted during transmission. Authentication: Make sure that the specified user can access only the specified data. At present, the popular front-end authentication way is Token form, can be the ordinary custom Token, also can be the JSON Web Token. The form of Token is obtained through BASIC authentication--The

Android is built on Linux on the OS, when it comes to security, network protocols, file encryption and other functions, often need to call the underlying API in C language to implement, and how to send instructions to the C side to perform the functions we want, and after the implementation of the return results? This requires the Java-side process and the C-side process to be made to communicate efficiently. Thus, the C-
