Université Catholique de Louvain: Olivier Bonaventure's "Computer Networking: Principles, Protocols, and Practice"
Read the introduction to Section 3.1, "Principles," on pages 27-30. Stop at Section 3.1.1.
As you read, consider these questions: What is the client-server model? What is the function of the client? Where does the server reside?
Note: On page 28, the textbook lists the binary code of A as "A : 1000011b." This is incorrect. The binary code for A should be: "A : 1000001b."
