Practical Guide – Hands-On Learning

Theory is important, but IT is a hands-on field. Here are two practical guides to get you started.

Lab 1 – Create a Folder in Windows (Using GUI)

Objective: Learn basic file management in Windows using the graphical interface.

Prerequisites: Windows computer with access to desktop

Step-by-Step Instructions:

Step 1: Right-Click on Desktop
Navigate to an empty area of your Windows desktop (avoid existing icons). Right-click (press the right mouse button).

Step 2: Hover Over “New”
A context menu appears. Look for “New” and hover your mouse over it. A submenu will expand.

Step 3: Select “Folder”
In the submenu, click on “Folder”.

Step 4: Name Your Folder
A new folder appears on your desktop, typically with a default name highlighted. Type your desired folder name:

textMy Super Cool Folder

Step 5: Press Enter
Press the Enter key to confirm the folder name.

Result: You’ve successfully created a new folder in Windows using the GUI!

What Just Happened Behind the Scenes:

• The kernel registered the new directory in the file system
• The folder was created in the default location (Desktop)
• The file system updated the folder structure
• The GUI displayed the new folder visually

Next Steps:

• Double-click to open your folder
• Drag files into it from other locations
• Right-click to rename, delete, or modify properties

Lab 2 – Create a Folder in Linux (Using CLI)

Objective: Learn the essential skill of creating folders using the Linux command line.

Prerequisites:

• Linux computer or VM (Ubuntu recommended)
• Terminal/Command line access

Why CLI Matters: This is where Linux power begins. Master this, and you’ve started your Linux admin journey.

Step-by-Step Instructions:

Step 1: Open the Terminal

• Method 1: Right-click on desktop and select “Open Terminal Here”
• Method 2: Use keyboard shortcut: Ctrl+Alt+T (on most Linux distros)
• Method 3: Find Terminal in applications menu

You should see a command prompt (blinking cursor) ready for input:

textuser@computer:~$

Step 2: Type the Command
Type the following exactly (Linux is case-sensitive):

bashmkdir my-super-cool-folder

Breaking Down the Command:

• mkdir — Command name, short for “make directory”
• my-super-cool-folder — The name of the folder you want to create
• Directory is another word for “folder”

Step 3: Press Enter
Press the Enter key to execute the command.

What Happens:
The folder is created silently. There’s typically no confirmation message. In Linux, “no error = success.”

Verify It Worked:
To confirm the folder was created, type:

bashls

This lists all folders and files in your current directory. You should see my-super-cool-folder in the output.

What Just Happened Behind the Scenes:

1. The kernel processed your mkdir command
2. The kernel created a new directory structure
3. The file system registered the new folder
4. The folder now exists on your hard drive
5. The terminal returned to the command prompt

Key Differences – GUI vs. CLI

Important Takeaway: Both approaches do the sam
