  • 🖥️ Central Processing Unit (CPU): The 'brain' of any computer system, responsible for executing instructions. Found in laptops, smartphones, and even smart appliances.
  • 💾 Random Access Memory (RAM): Temporary storage that holds data the CPU is actively using. More RAM means smoother multitasking. Think of it as the computer's short-term memory.
  • 💽 Hard Disk Drive (HDD) / Solid State Drive (SSD): Long-term storage for files, applications, and the operating system. HDDs use spinning disks; SSDs use flash memory for faster access.
  • 📺 Monitor: Displays visual output from the computer. Comes in various sizes and resolutions.
  • 🖱️ Mouse: An input device used to control the cursor on the screen.
  • ⌨️ Keyboard: An input device used to enter text and commands into the computer.
  • 📡 Network Interface Card (NIC): Allows a computer to connect to a network (e.g., Ethernet or Wi-Fi).
  • 🔊 Speakers: Output devices that produce sound.
  • 📸 Webcam: A video camera connected to a computer, often used for video conferencing.
