Welcome to “Exploring Linux Operating System Essentials.” After watching this video, you will be able to: Explain why companies adopt Linux. Describe how to create a local system account and confirm its settings. Explain how to view system information. Describe how to use the Ubuntu file system. And explain how to monitor system performance. As an open source operating system, multiple vendors offer Linux operating system, or OS, versions. Some OS versions include user-friendly graphical user interfaces similar to Windows, while others focus on command-line interfaces and capabilities. But no matter which vendor or version, Linux is often the operating system that organizations and their programmers prefer because of its stability, security, and efficiency. Linux versions are known as “distributions” or “distros.” Popular vendors include Debian, Red Hat, Linux Mint, Ubuntu, OpenSUSE, and others. Canonical distributes Ubuntu, a Linux version with a lightweight, easy-to-use graphical interface. And Canonical reports more than 40 million users as of 2021, making Ubuntu’s graphic interface a widespread Linux distribution. Linux is available preinstalled on servers and laptops. But you can also download a “base” Linux operating system and install the system to the workstation using a thumb drive, CD, or network drive. And after you connect to the web to finish your installation, you can complete your workstation setup. Let’s begin with an installed version of Ubuntu. To set up a local account, you need to first log in as the Administrator. Next, you’ll create a local system account that doesn’t have administrative rights. Local accounts are typically shared with computer users and do not permit administrative rights. Next, click Activities. And in the search bar, begin typing the word “user,” and then select Settings. In the Settings pane, select Users and then select Unlock. Type the Administrator password. Next, you’ll add the user’s local account information. In the Users window, select Add User… In the Add User dialog box, select the Standard tab. Type the user’s Full Name and Username. In this example, you see the new user shown as Newuser1. Select the Allow user to set a password when they next login option and click Add. Next, locate the Power Off/Log Out option. Click the expander arrow and select Switch user … Select NewUser1. Now, type the new password, “Change Me exclamation point 234” and press Enter. Again, click Activities Then, in the search bar, type the word “user” and select Settings. Select Users in the Settings pane. Then select the NewUser1 tab to confirm the account information. And you’ll see the user’s Account Settings below the user’s name. Next, let’s learn how to locate system hardware and operating system information. You can quickly locate system hardware and operating system information, including the operating system version and build number. Here’s how: Select Activities. In the search bar, type “About” and press Enter. Then click the Settings option About: View information about your system. You’ll see the device name, hardware module, memory, processor graphics card, disk capacity, OS name, OS Type, GNOME version, Windowing System, Virtualization, and Software update status. Let’s now quickly access folders and files by selecting either the Files icon in the left navigation pane or the Home Folder on the desktop. On the Home screen, you’ll see an easy-to-navigate, familiar folder structure. This file structure includes preconfigured folders for desktop, documents, music, pictures, templates, videos, and other categories of files. To create a new folder, on the Home screen, within Folders, right-click and select New Folder. And name the new folder Test Folder 1, for example. Next, double-click Test Folder 1 to view its contents. In this empty folder, let’s create a file. Select the LibreOffice document icon, and a document opens. Add some text to the file. For example, “Test: Creating a file.” Select File and Save or Save As. Then select the destination folder and save this new file in that folder. Nowclose the document. Finally, confirm that your file is in the correct folder. On the Home screen, double-click Test Folder 1, and you’ll see the Test1.odt file. Next, let’s look at where you can find system performance information. To monitor system performance, view the Activities screen and click Activities. Within the search bar, type “System” and select the System Monitor App. The System Monitor App provides essential CPU, RAM, disk, and priority performance information to help you troubleshoot performance-related issues, such as applications that stall or lag. The app organizes this information in the Processes, Resources, and File Systems tabs. In this video, you learned that: Organizations adopt Linux because of its stability, safety, and efficiency. You first log in as an Administrator to create user accounts. You can set a user account so that the assigned user sets their password the first time they use the workstation. You also learned that: You can select About and click About: View information about your system to view your computer’s name, memory, installed version of Ubuntu, as well as verify operating system updates, and more. To locate files and subfolders, select the Folders icon within the left navigation pane on the Home screen And finally, the System Monitor App organizes system performance information in the Pr
