Answer 1

Correct Answer - Option 3 : Modem

The correct answer is Modem.

• A Modem is used to transfer the digital signals between the computer and the communications channel.

• A modem is a short form of modulator-demodulator.
  • It is a hardware device that converts data from a digital format, intended for communication directly between devices with specialized wiring, into one suitable for a transmission medium such as telephone lines or radio.
  • A modem modulates one or more carrier wave signals to encode digital information for transmission and demodulates signals to decode the transmitted information.
  • The goal is to produce a signal that can be transmitted easily and decoded reliably to reproduce the original digital data.
  • Modems can be used with almost any means of transmitting analog signals, from light-emitting diodes to radio.
  • A common type of modem is one that turns the digital data of a computer into a modulated electrical signal for transmission over telephone lines, to be demodulated by another modem at the receiver side to recover the digital data. 

• A local area network (LAN) is a collection of devices connected together in one physical location, such as a building, office, or home.
  • A LAN can be small or large, ranging from a home network with one user to an enterprise network with thousands of users and devices in an office or school. 
• FireStick is an Android-based device. However, unlike most Android devices, FireStick does not support Google Play Services. 
• CD drive: A drive that reads a compact disc and that is connected to an audio system.
  • CD player - a stand-alone piece of electronic equipment that either has its own display or attaches to a television set.
