Correct Answer - Option 1 : Allow the computer to store data electronically

The correct answer is to Allow the computer to store data electronically

  • The random access memory (RAM) is in the form of computer chips. Usually, the contents of RAM are accessible faster than other types of information storage but are lost every time the computer is turned off.
  • RAM is the memory or information storage in a computer that is used to store running programs and data for the programs.
  • Data (information) in the RAM can be read and written quickly in any order.
  • RAM is volatile memory, which means that the information temporarily stored in the module is erased when you restart or shut down your computer. Because the information is stored electrically on transistors, when there is no electric current, the data disappears. Each time you request a file or information, it is retrieved either from the computer's storage disk or the internet.
  • Types of RAM:
    • Static RAM, or (SRAM) stores a bit of data using the state of a six transistor memory cell.
    • Dynamic RAM, or (DRAM) stores a bit of data using a pair of transistors and capacitors which constitute a DRAM memory cell.

  • Difference between RAM and ROM:
    1. RAM, which stands for random access memory, and ROM, which stands for read-only memory, are both present in your computer.
    2. RAM is volatile memory that temporarily stores the files you are working on. ROM is a non-volatile memory that permanently stores instructions for your computer.
  • Primary memory is also called internal memory whereas Secondary memory is also known as Backup memory or Auxiliary memory.
  • Two types of Primary Memory are RAM and ROM.
  • Primary memory can be accessed by the data bus whereas Secondary memory is accessed by I/O channels.
  • Primary memory data is directly accessed by the processing unit whereas Secondary memory data cannot be accessed directly by the processor.
