Lesson 6 - Information Flow Between Client and Server

   Introduction

In this unit, we have discussed some of the many hardware and software elements that make up a LAN. This lesson shows how those devices and protocols work together to perform a common task, such as allowing a client to read a file stored on a server attached to the same physical network.

   Objectives

At the end of this lesson you will be able to:

1.	Describe how the format of information changes as it flows between client and server
2.	Explain the purpose of the Server Message Block (SMB) protocol

Key Point
The SMB protocol uses Request/Reply pairs to communicate between clients and servers.
