The Intermediate CompTIA A+ Certification Prep course picks up where the Basic course left off and plunges you head-first into Windows, macOS, and Linux. You learn how to install, organize, maintain, and troubleshoot three different versions of Windows, plus explore similar features in macOS and Linux. You'll examine and compare the features and structures of Windows Vista, 7, and 8/8.1. I'll even throw in some Windows 10 because it's cool. Toward the end of the course you'll get a deeper understanding of how we use virtualization and virtual machines in modern networks. Plus you'll learn about printers and multifunction devices, from the various technologies in use to installing and troubleshooting. This course takes you through the second of three steps you need to become both a highly-competent PC tech and a CompTIA A+ certified technician, using the 901 and 902 competencies.
