"Network+ 2005 In Depth" gives you all the skills that you need to pass the CompTIA 2005 Network+ exam. Begin with an introduction to the fundamental building blocks that form a modern network, such as protocols, topologies, hardware, and network operating systems. Then, dive into the most important concepts in contemporary networking, such as client/server architecture, TCP/IP, Ethernet, wireless transmission, and security. When you are finished, you will be prepared to select the best network design, hardware, and software for your environment. You will also have the skills to build a network from scratch and maintain, upgrade, and troubleshoot an existing network. CoursePrep Exam Guide available on Companion Web Site!
