TAILIEUCHUNG - Managing Network Connections

C ommunications over a network are accomplished through the use of networking protocols. To understand the purpose of networking protocols, you should have a basic knowledge of the OSI (Open Systems Interconnection) model . The OSI model is not an actual product. It is a theoretical model that describes how networks work. | Chapter Managing Network Connections MICROSOFT EXAM OBJECTIVES COVERED IN THIS CHAPTER Install configure and troubleshoot network adapters. J Configure and troubleshoot the TCP IP protocol. Î 1 Copyright 2000 SYBEX Inc. Alameda CA. or successful network connection management you need to understand how network protocols work. The OSI model helps you gain this understanding by showing how network protocols are modular in nature. Network adapters are hardware used to connect your computer to the network. You also need a driver for the network adapter installed on your computer. Managing network connections also involves configuring your network protocols. The three protocols supported by Windows 2000 Professional are TCP IP NWLink IPX SPX NetBIOS and NetBEUI. This chapter begins with an overview of network protocols including a discussion of network data flow and the OSI model. Then you will learn how to install and configure network adapters and network protocols. Reviewing Networking Protocols Communications over a network are accomplished through the use of networking protocols. To understand the purpose of networking protocols you should have a basic knowledge of the OSI Open Systems Interconnection model. The OSI model is not an actual product. It is a theoretical model that describes how networks work. There are several advantages to using the OSI model as a framework for understanding network protocols Breaking down a large concept such as a network makes it easier to understand. Copyright 2000 SYBEX Inc. Alameda CA. Reviewing Networking Protocols 497 Modularizing network functions allows you to apply specific technologies or protocols at specific layers in a mix-and-match manner. Understanding how one network system works and applying it to the OSI model allows you to easily apply that knowledge to other operating systems. We ll start by looking at an example of how data flows through a network. Then we ll examine how the seven .
