Network: group of computers and other devices that are connected by some type of transmission data. Advantages of using networks over standalone computers: Networks enable multiple users to share the network’s resources (devices and data) Networks allow you to manage, or administer, resources on multiple computers from a central location Network+ Guide to Networks, 4e TYPES OF NETWORKS: PEER-TO-PEER NETWORKS Every computer | NETWORK+ GUIDE TO NETWORKS, FOURTH EDITION Chapter 1 An Introduction to Networking OBJECTIVES List the advantages of networked computing relative to standalone computing Distinguish between client/server and peer-to-peer networks List elements common to all client/server networks Describe several specific uses for a network Identify some of the certifications available to networking professionals Identify the kinds of nontechnical, or “soft,” skills that will help you succeed as a networking professional Network+ Guide to Networks, 4e WHY USE NETWORKS?
