Which of the following statements about internal and external computer memory are true? A. A portable hard drive is an example of internal memory B. Magnetic tape is used to store backups of data C. RAM is an internal memory D. ROM loses its data when the power is turned off Choose the correct answer from the options given below Correct Answer B and C only

computer memory is referred to as storage space in a computer where data to be processed and instructions to be processed are stored.

Key Points

  • Computer memory is a device that stores data or programs for use in an electrical digital computer on a temporary or permanent basis.
  • Only the data and instructions on which the computer is presently working are stored in primary memory.
  •  The main memory stores the data and instructions that must be processed.
  • RAM and ROM are the two subcategories of memory.
  • RAM is Internal memory, which has limited capacity, data is lost after power is turned off.  
  • RAM is directly connected to the CPU through the memory bus, the CPU can instantly retrieve data stored in RAM.
  • Read-Only Memory, or ROM, is a type of non-volatile memory that retains data even after the power is switched off.

Therefore, the B and C statements are correct. 

Additional Information

  • Information is stored in computers as binary code, which is written as a series of 0s and 1s. 
  • A hard drive or solid-state drive (SSD) connected to a computer from the outside rather than the inside is referred to as an external drive.
  • Speech and music are recorded on magnetic audiotape, whereas magnetic videotape is a low-cost medium for recording analog voice and visual signals directly and simultaneously.

Based on the paragraph given below answer the following question: The traditional methods of combinational circuits involve simplification and realization using gates. Using these methods, complex functions have been integrated and are easily available in IC form. There is an attractive array of devices like a multiplexer, demultiplexer, decoders, comparators, parity generators/checkers, which significantly reduce IC package count there by reducing the system cost. The system design is greatly simplified because the laborious and time-consuming simplification methods are generally not required with these devices. This also improves the reliability of the system by reducing the number of external wired connections. But they have some limitations as well. Different memories like ROM, PROM can also be used to implement combinational circuits without much simplification.   A ROM is to be used to implement a “Squarer”, which outputs the square of a 3-bit number. What must be the size of the ROM?
