- Answer: Keyboard (inputs data), Mouse (navigates), System Unit (processes), and Monitor (displays output).
- Description: The keyboard types data, the mouse controls the cursor, the system unit (with CPU) processes everything, and the monitor shows results. These are the essentials you interact with daily, forming a complete hardware setup.
2.
- Answer: USB connects devices (e.g., flash drives), RJ 45 links to networks (e.g., Ethernet), and video ports (e.g., HDMI) output to displays.
- Description: USB is versatile, plugging in mice or storage. RJ 45 connects to the internet via cables, vital for LANs. Video ports send graphics to monitors, like HDMI for HD screens. Knowing these helps students set up hardware correctly.
