All rights reserved.Cisco Confidential Chapter 15: Critical Concepts  What is this chapter about and why is it important?  A computer technician can no longer just be responsible for computers and the things that are connected to them. Instead, a technician today must place that computer on a wired or wireless network and ensure that it is able to participate in that network. Additionally, devices such as a printer or scanner, and individual files and folders must be made available to other users or other devices on the network. A technician now must understand the basics of a TCP/IP-based network and Internet connectivity. A technician must be able to ensure that each device functions, is secure, and communicates with other devices and sites in a network environment. It is important for an instructor to fully prepare students to work as technicians in a network environment.  This chapter covers safety hazards, network components that are included in a network environment, and Internet connectivity options. The chapter takes the basic networking concepts to the next level of implementation with design and preventive maintenance. Troubleshooting common network problems are also included.
