Which device is required for the Internet connection?

The correct answer is Modem because it modulates and demodulates analog and digital signals to establish communication with your Internet Service Provider (ISP).

• Modem: This is the correct choice. A modem (MOdulator-DEModulator) translates digital data from a computer into an analog signal for transmission over telephone or cable lines, and vice versa. While a Network Interface Card (NIC) connects a computer to a local network, a modem is traditionally required to bridge that network out to the wider internet.


• Incorrect Options:
  
  
  
  • Joystick: This is incorrect. A joystick is an auxiliary peripheral device used primarily for gaming control, not network communications.
  
  
  • CD Drive: This is incorrect. A CD drive is an optical storage system read/write hardware component with no networking capabilities.
  
  
  • NIC Card: This is incorrect. While a Network Interface Card connects a machine to a local wired or wireless link, it cannot connect to an outside internet provider line without an intermediary gateway device like a modem.
