When you interact with a computer system, you're usually doing so as a user. Each user has an account with specific permissions that dictate what they can access or modify.

When you open a command line (often called a terminal or shell), you're usually placed in your "home directory." This is your personal starting point. From there, you'll use commands to explore and manipulate your file system.

When you're working on a project, especially with others, things can get messy. You might accidentally delete something important, want to revert to an earlier version, or need to combine work from multiple people. That's where Git comes in.

Git helps you manage these scenarios by tracking every change you make to your files. It doesn't just save the whole file again; it cleverly saves the differences between versions, which is very efficient.

You might use computers every day, but do you really know what's going on inside? This course isn't just about using software; it's about understanding the foundational concepts that make computers tick. We'll start with the basics, moving from hardware to software, and then to how computers connect and communicate.

The command line lets you interact with your computer by typing text commands. You'll typically use a program called a "terminal," "console," or "shell" (like Bash, Zsh, or PowerShell) to do this. Each command generally follows a pattern: command [options] [arguments].

• command: The action you want to perform (e.g., ls to list files, cd to change directories).
• options (or flags): Modify the command's behavior, usually starting with a hyphen (e.g., -l for a "long" list, -a for "all" files).
• arguments: What the command acts upon (e.g., a file name, a directory path).
