Hello World TCP Server using Sockets (2)

In this video we continue coding our "Hello World" server. We will now encounter the most important API call - accept() ( from a server's perspective ). Accept() allows the server process to accept client connections and process them. We will currently run the server in an infinite loop, so that we can process clients one after the other. The important thing to note here that this server process is not multithreaded and thus can only process a single client at a time. To be able to process multiple clients asynchronous calls such as select() or multithreading will have to be used.
