In this brief video series, you'll see a demo of the Microsoft Windows, Apple macOS, and Ubuntu desktop Linux distribution. For the most part, each of these operating systems perform the same basic functions. How you operate some of these functions differs among them. After logging in, you're presented with your desktop, which is similar for each of the three operating systems that you'll see in this course. Now I'm demoing Ubuntu desktop, which is a Linux distribution. You can download and install Ubuntu for free. Both Windows and macOS do not have that option so that's one advantage of using Linux and Ubuntu in particular. You'll also see if you are familiar with Windows and, or macOS, Ubuntu gives you somewhat similar feel, which is part of the reason it was selected for this course. A quick walk-through of Ubuntu Linux, here across the top bar is where you'll have your date and time in the center here. On the left-hand side is the Activities button. Clicking on that gives me a search where I'm able to search for files, folders, applications that would be installed on this particular computer. On the right-hand side, I have a drawer here that has various workspaces, so I can have applications assigned to each workspace on the computer, and be able to easily switch between those to keep focused on a particular project or task. Clicking "Activities" again, will close that particular window, and then your open applications will show up to the right of Activities here. If I open Firefox, you'll see that opens, if I open files, you'll see that's open now, as well as you get a little dot here next to the application icons that will show you which applications are running. Now if I'm in Firefox, which is a web browser, I can click this down arrow and get my menu, that I would have for that browser. Similar to what we had in Windows, we can minimize applications, we can maximize or restore down the size of our applications, and we also have an X to close out applications here. On the top right-hand corner, you have Network Settings, you have a Volume button. If you're running on a laptop, you'll see a battery icon that will show the battery charge level. Then you also have in the very top right-hand corner System Indicators, and this will give you quick access to Settings. If I click on ''System Indicators'', again, you'll see volume here, some network settings, battery, but then other settings similar to what we had in Windows where I can change wallpaper, I can install printers, I can make changes to users permissions, I can lock the computer, I can shut down, restart, log out of my current user just as I could with Windows. Again down the left-hand side here we have all of our applications. Sometimes this is called a Dock, sometimes it's called a Launcher. But this gives us quick access to programs and files, just like the Taskbar did in Windows and the Dock does in macOS. All the way in the bottom left corner is our App Drawer. This allows us to see applications that are installed on the computer. You can see here we have two different tabs. One is for all and one is for frequently used, and there's also a search here, just like we saw in Activities. I can also scroll if I had more applications on here. These dots here allow you to scroll through pages of applications. Clicking on the "App Drawer" again, will high that away, take you back to where you were. Lastly, similar to what we saw in Windows, I do have a File Explorer. If I go into my documents here, I can right-click add a new folder, and I can create organization throughout my computer here, I can also right-click and change properties. You can do this in Windows as well, you can set permissions, you can rename folders, you can see how much space is left on a computer in this way. Again, I get this X to close out those Windows. What I don't have here is right-click to create a file. Instead, I would need to find in this case, my document where processing application, I would just start that application. I can save my work in there to this location, but in Ubuntu I cannot right-click here and automatically create that file. That's a quick walk-through of Ubuntu desktop, which runs Linux.
