How should I learn server client programming?

I’m just a beginner in java (its almost same as C++) and I’m trying to understand the concept of servers. I searched many places but still I don’t get a satisfactory answer. I want an answer of programmer’s level, rather than names of server hosting companies, cause I wanna make my own server (well, yeah I’m still learning programming, but does it matters?) I also wanna know about UE and virtual server and can I make virtual server for MMORPG in windows or if possible, in android. Its MMORPG cause there are multiple games which I wanna connect to one server only, allowing the players from different games to interact, despite the fact that they are in different games. And one more thing, I don’t have a clear concept of network (and also server) programming and I’m just unable to understand how can a server send same data to many clients at the same time. Can anyone tell me?

Unreal has a lot implemented under the hood (such as the communication between a server and a client), and you should first understand how it works, before to move on.

To get you started, I suggest you look at this video tutorial here: Blueprint Networking Tutorials - Unreal Engine

Then, here is a very useful compendium:

Finally, don’t forget to have a look at the documentation here: Networking and Multiplayer | Unreal Engine Documentation

If you need a tutorial, recently on the Unreal Blog they have suggested this one: Unreal Engine 4 Mastery: Create Multiplayer Games with C++ in New Course from Udemy - Unreal Engine after a short overview of Multiplayer Games here: Getting Started with Unreal Multiplayer in C++ - Unreal Engine

Hope these links are useful, if you have any other questions, please don’t hesitate to ask.

Wow thanks for that answer. I have not yet seen all of them but it seems like these will clear all my curiosity. Once again, thanks!

You are very welcome.
