Setting Up the Network Client A network is a group of computers, peripherals, and software that are connected to each other and can be used together. Special software and hardware are required to make networks work. Two or more computers connected together in the same office are considered a LAN (local area network). LANs in different cities can be connected to each other by a WAN (wide area network). The Internet represents the world's largest network, connecting both standalone computers and computers on LAN and WAN networks all over the world. This chapter is a little different than other chapters in this book in that it covers topics found on both the A+ Core Hardware and A+ Operating Systems Exams. Because both exams deal with networking topics, covering all the networking topics in a single chapter makes more sense than creating two chapters with overlapping subjects.  | The CD included with this book contains important Study Lab material for this chapter, as well as Chapters 2 “22 in this book. The Study Lab for each chapter contains terms to study, exercises, and practice tests ”all in printable PDF format (Adobe Acrobat Reader is included on the CD, too). These Study Lab materials will help you gear up for the A+ Exam. Also, the CD includes an industry-leading test engine from PrepLogic, which simulates the actual A+ test so that you can be sure that you're ready when test day arrives. Don't let the A+ test intimidate you. If you've read the chapters, worked through the Study Lab, and passed the practice tests from PrepLogic, you should be well prepared to ace the test! Also, you'll notice that some words throughout each chapter are in bold format. These are study terms that are defined in the Study Lab. Be sure to consult the Study Lab when you are finished with this chapter to test what you've learned. |
