Introduction to Computer Networking
... We use the terms “client” and “server” in the following sense. When two entities say A and B, want to communicate, there is a boostrap problem: how can you initialize both A and B such that the communication can take place. One solution is to manually start A, then B, but this defeats the purpose of ...
