Which of the following is true regarding to ROM? (i) It is a volatile memory. (ii) It is a non-volatile memory. (iii) It is both a volatile and a non-volatile memory.

Which of the following is true regarding to ROM? (i) It is a volatile memory. (ii) It is a non-volatile memory. (iii) It is both a volatile and a non-volatile memory. Correct Answer Only (ii)

The correct answer is Only (ii)

  • ROM is a non-volatile memory.
  • Non-volatile memory,  NVM, or non-volatile storage is a type of computer memory that can retrieve stored information even after having been power cycled (turned off and back on).
  • Whereas Volatile memory is the memory that can not be retrieved after having been power cycled.

Additional Information

  • Examples of non-volatile memory include read-only memory, flash memory, ferroelectric RAM, most types of magnetic computer storage devices (e.g. hard disk drives, floppy disks, and magnetic tape), optical discs, and early computer storage methods such as paper tape and punched cards.
  • Examples of volatile memory include RAM.

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?
Two processes X and Y need to access a critical section. Consider the following synchronization construct used by both the processes Process ? /* other code for process ? */ while(true) { varP = true; while(varQ == true) { /* Critical Section */ varP = false; } } /* other code for process ?? */   Process ? /* other code for process ? */ while(true) { varQ = true; while(varP == true) { /* Critical Section */ varQ = false; } } /* other code for process ? */   Here, varP and varQ are shared variables and both are initialized to false.
