The correct answer is a - ii, b - iii, c - iv, d - i.Key Points

•  Magnetic Tape
  • It is a medium for magnetic storage.
  • It is made of a thin, magnetizable coating on a long, narrow strip of plastic film.
  • It is Auxiliary Storage Device, which means it is an external storage device.
  • In the magnetic tape, only one side of the ribbon is used for storing data.
  • It is sequential memory which contains a thin plastic ribbon to store data and is coated by magnetic oxide.

Additional Information

• Random access memory (RAM)
  • ​It is a type of data storage used in computers that are generally located on the motherboard.
  • This type of memory is volatile and all information that was stored in RAM is lost when the computer is turned off.
  • There are two main types of RAM: Dynamic Random Access Memory (DRAM) and Static Random Access Memory (SRAM).
• Laser Printer
  • It is a type of computer printer that uses non-impact photocopier technology where there are no keys striking the paper.
  • Hence, it is an output device.
• Light pen
  • ​It is a light-sensitive computer input device
  • It is used to select a displayed menu item or draw pictures on the monitor screen.
  • Hence, it is an input device.
