Managing Linux

So far in this course, you worked mostly with the Microsoft Windows operating system. A CompTIA A+ technician should be capable of supporting diverse OS environments. The various operating systems you might encounter use different interfaces and command syntax, but the functionality of those tools is common across all types of systems. You will need to configure disks and file systems, user accounts, network settings, and software applications. Lesson Objectives

In this lesson, you will:

  • Identify features of Linux.
  • Identify features of macOS.

You should be able to identify features of Linux and macOS to help support diverse OS environments.
