Why a ROM does not have data inputs?

Why a ROM does not have data inputs? Correct Answer It does not have a WRITE operation

ROM (Read-only memory):

  • It is a type of non-volatile memory used in computers and other electronic devices.
  • Data stored in ROM cannot be electronically modified after the manufacturing of the memory device.
  • ROM is useful for storing software that is rarely changed during the life of the system also known as firmware.
  • Strictly ROM refers to memory that is hard-wired such as a diode matrix or a mask ROM integrated circuit which cannot be electrically changed after manufacturing.
  • ROM does not have data inputs because it does not have a WRITE operation.

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?
Which of the following statements are true?
Statement I Big data refers to no precise quantity, but generally refers to data in the range of Petabytes and Exabyte, i.e. billions to trillions of records, all from various sources. Big data is generated much faster. than traditional data in much larger quantities.
Statement II Big data interests industries because they are able to learn more patterns and curious variances than smaller data sets, with the capability to provide valuable insights into consumer behaviour, weather systems, financial market activity, or other phenomena.
Statement III Various departments and product lines use various applications within most organisations and store data in separate datasets. These separate databases may contain similar data, but data from one data base to another is not always consistent. This is called data silo.
