Jason’s Computer Science Blog - » Tutorial: sockets – 3 ways to listen. As you may know, I have been ta-ing a course in operating systems. We just finished covering sockets and in the last lab I gave a socket demo where I show three different ways a server can listen on a socket. First is a very basic case where the server can only accept and process one connection at a time. Second I show the fork()ing case where multiple connections can be processed concurrently using multiple processes. Lastly, the multiple connection case is handled with select() so that everything can be handled in a single connection. Single connection server This server is a basic echo server.

The major weakness of this server is that it can only handle a single connection at once. Fork() – Multiple connection, multiple process In this case, the server can now handle multiple connections successfully. Notice that the processing portion of the code has been moved into a function which is called when the fork() is executing within the child processes.

What was once an unusual profession transferred into a word indicating social awkwardness.

A geek is one who isn’t satisfied knowing only the surface facts, but instead has a visceral desire to learn everything possible about a particular subject. A techie geek is usually one who knows a little about everything, and is thus the person family and friends turn to whenever they have a question.
