📚 What is a Computer Case?
The computer case, also known as the system unit, tower, or chassis, is the enclosure that houses all the essential internal components of a computer. Think of it as the body that protects the computer's vital organs.
🛡️- Protection: Shields internal components from physical damage and dust.
🌡️- Cooling: Provides space and mounting points for cooling solutions like fans and heatsinks.
🔌- Organization: Helps organize internal components and cables for better airflow and accessibility.
⚡️- Electromagnetic Interference (EMI) Shielding: Reduces interference with other electronic devices.
⌨️ What is a Keyboard?
The keyboard is an input device that allows you to enter data and commands into the computer. It's the primary way we communicate with a computer by typing text, numbers, and symbols.
✍️- Input: Allows users to input text, numbers, and symbols.
🧮- Commands: Used to execute commands and navigate the operating system.
🎮- Gaming: Essential for controlling actions and movements in video games.
⚙️- Customization: Many keyboards offer customizable keys and layouts for different tasks.
