In this example we shall build a basic ECHO client and server. The server/client shown here use TCP sockets or SOCK_STREAM. TCP sockets are connection oriented, means that they have a concept of independant connection on a certain port which one application can use at a time. The concept of connection makes TCP a "reliable" stream such that if errors occur, they can be detected and compensated for by resending the failed packets.
Server
Lets build a very simple web server. The steps to make a webserver are as follows :
1. Create socket
2. Bind to address and port
3. Put in listening mode
4. Accept connections and process there after.
