Question

In a protocol named for these objects, frames contain a random 32-bit “masking key” to protect against proxy cache poisoning, and the three types of control frames are Close, Ping, and Pong. IPC can be implemented with the “Unix domain” type of these objects, which use the (15[1])AF_UNIX family instead of the more typical AF_INET (“A-F I-net”). The getaddrinfo (“get adder info”) function is typically called to retrieve the arguments (15[1])for initializing these objects. The two main kinds of these objects are labeled “stream” and “dgram”, while the (*) “raw” kinds of these objects don’t use any transport layer protocol. (-5[1])A popular JavaScript library for bidirectional client-server communication is named “[this word].io”, (10[1])which is built on a communications protocol called “Web [this word]”. For 10 points, name these network endpoints that send and receive data, which are located at some IP address and port number. ■END■ (0[1])
