Best answer
Correct Answer - Option 4 : ROM

The correct answer is Read-Only Memory (ROM)

 

  • ROM stands for Read-Only Memory.
  • ROM is a storage device that is used with computers and other electronic devices.
  • Data stored in ROM may only be read.
  • ROM is used for firmware updates, which means It contains the basic instructions for what needs to happen when a computer is powered on.
  • Firmware is also known as BIOS, or basic input/output system. 
  • ROM is non-volatile storage, which means the information is maintained even if the component loses power.
  • ROM is located on a BIOS chip which is plugged into the motherboard.
  • ROM plays a critical part in booting up or starting up, your computer.

Terminologies Characteristics

Random Access Memory (RAM)

 
  • This memory allows writing as well as reading of data, unlike ROM which does not allow writing of data on to it.
  • It is volatile storage because the contents of RAM are lost when the power (computer) is turned off.
  • If you want to store the data for later use, you have to transfer all the contents to a secondary storage device.
Dynamic random access memory (DRAM)
  • It is a type of semiconductor memory that is typically used for the data or program code needed by a computer processor to function.
  •  DRAM is a common type of random access memory (RAM) that is used in personal computers (PCs), workstations and servers.
Cache
  • Cache primarily refers to a thing that is hidden or stored somewhere, or to the place where it is hidden.
  • It has recently taken on another common meaning, “short-term computer memory where information is stored for easy retrieval.”
