What things do you have to plug in to use?

To use electronic devices like a computer, you typically need to plug in the power cord to an electrical outlet. Additionally, peripherals such as a monitor, keyboard, and mouse may require separate connections. Some devices, like printers or external hard drives, may also need to be plugged into a USB port for data transfer and power. Finally, internet-connected devices might require an Ethernet cable or need to be plugged into a Wi-Fi router.
