Using the Desktop: Files, Folders, Settings and Installing Software

Hello students, welcome to Kwickprep. You switch on a computer and a screen full of small pictures appears. Where do you click first, and where do your files go? Today we will learn the desktop, files and folders, settings, and how to install and remove software safely.

Let us begin with the desktop. The desktop is the first screen you see after you log in to the computer. Think of it like the top of your study table, where you keep the things you use most. It shows small pictures called icons, a background picture called the wallpaper, and a long bar called the taskbar.

Here are the parts of the desktop you must know. An icon is a small picture for a program, file or folder, like the Recycle Bin. A shortcut icon is only a link, so deleting it does not delete the real program. The taskbar is the bar at the bottom that shows the apps now open. The Start menu opens from the Start button and lists all installed apps. The notification area near the clock shows Wi-Fi, sound and battery.

Now, how do we use icons? Double click an icon to open it. Right click an icon to see a short menu of options, like Open, Rename or Delete. Drag an icon, which means hold the button and move the mouse, to place it somewhere else. Windows and Ubuntu Linux look a little different, but these actions work the same way on both.

Next, two very important words. A file is one saved item, like a photo, a song or a letter you typed. A folder is a container that holds files, just like a school file folder holds papers. A folder can also hold other folders, and these are called subfolders. The letters after the dot in a file name are the extension, and they tell the file type, such as .docx, .jpg or .pdf.

Let us create a folder for your Science notes. First, open File Explorer, the program that shows your drives and folders. Right click on an empty space inside the window. Choose New, and then Folder. Type a clear name, like Science Notes, and press Enter. To rename it later, right click it and choose Rename, or select it and press F two.

Here are the everyday file tasks. Copy makes a second copy and keeps the original, using control C. Cut is used to move a file, using control X, and the file leaves its old place after you paste. Paste puts the copied or cut item in the new folder, using control V. Delete removes the item, using the Delete key. Rename changes the name, using F two.

What happens when you delete a file by mistake? Deleted files first go to the Recycle Bin, which Ubuntu calls the Trash. Open the bin, right click the file and choose Restore, and it goes back to its old folder. If you empty the bin, the files are removed for good. Shift plus Delete skips the bin completely, so use it with care.

Pause and predict. You delete the Chrome shortcut icon from the desktop. Is the Chrome program now removed from the computer? No, it is not. A shortcut is only a link, so the program stays installed and still opens from the Start menu.

Now, where do we change how the computer works? The Control Panel is the classic Windows window that holds system options. In Windows 10 and 11, most options have moved to the newer Settings app, though Control Panel is still there. Ubuntu Linux has its own Settings window with similar options. You can open any of them by searching from the Start menu.

Here are the settings students use most. Display changes the screen, like brightness and text size. Personalisation changes the wallpaper, colours and theme, like dark mode. Date and time sets the clock and time zone, which for India is plus five thirty. Network connects you to Wi-Fi or the internet. Accounts adds users and changes passwords, and it often needs an administrator, the user with full control.

Next, installing software, which means adding a new program to the computer. Use the official app store, like Microsoft Store or Ubuntu's App Center, or the maker's own website. Check the app name, the maker and the reviews, because fake apps copy famous names. Read every install screen, and untick any extra toolbar or offer you did not ask for. Never install cracked or pirated software, because it often hides malware, which is harmful software.

To remove software, we uninstall it, and never just delete its folder. First, open Settings. Go to Apps, and then Installed apps. Find the app in the list. Choose Uninstall and follow the steps. In Control Panel, the same option is called Programs and Features, and Ubuntu removes apps from App Center.

Let us revise what we learned today. The desktop has icons, the taskbar and the Start menu. Files are kept inside folders and subfolders. You can copy, cut, paste, rename and delete, and the Recycle Bin can bring a file back. Control Panel and Settings change how the system works. Install software only from official sources, and remove it with Uninstall.
