I'm only going to talk about INET (i.e. IPv4) sockets, but they account for at least 99% of the sockets in use. And I'll only talk about STREAM (i.e. TCP) sockets - unless you really know what you're doing (in which case this HOWTO isn't for you!), you'll get better behavior and performance from a STREAM socket than anything else.Conclusion. Both of them are useful while creating web pages. When the traditional request-response is required then, Ajax can be used, and when there is real-time communication involved and fast results are needed, then web sockets can be used. The connection, once established, will need fewer resources than Ajax requires. nosler partition 308 165 grain ballisticsJul 05, 2022 · One popular choice for implementing WebSockets is the Socket.IOlibrary.
