Question

State whether given statement is true or false
RAM and ROM are the types of external memory.
A. True
B. False

Answer 1

Hint:Our machine contains both RAM, which stands for random access memory, and ROM, which stands for read-only memory. RAM is a volatile memory that holds the files we're operating on temporarily. The ROM is a non-volatile memory that holds our computer's instructions indefinitely.

Complete answer:
A random-access memory system enables data objects, regardless of the actual location of data within the memory, to be read or written in about the same amount of time. In comparison, for other direct-access data storage formats, such as hard discs, CD-RWs, DVD-RWs, and older magnetic tapes and drum memory, due to technical constraints such as media rotating speeds, the time taken to read and write data objects differs greatly based on their physical location on the processing medium.
To link the data lines to the addressed storage for reading or writing the entry, RAM includes multiplexing and demultiplexing circuitry. The data stored in the ROM cannot be remotely changed until the memory unit has been manufactured. For storing information that is rarely updated over the life of the device, also known as firmware, read-only memory is useful. Computer (like video games) programmes for programmable machines can be sold as ROM-containing plug-in cartridges.

So, from the above information it can be gathered that RAM and ROM are not external memories. Hence, option B is correct.

Note:Primary-volatile memory is Random Access Memory (RAM) and primary-non-volatile memory is read-only memory (ROM). A read-write memory or the main memory or the primary memory is also referred to.The ROM is a memory that a programme or user will not modify. And after the machine is switched off the ROM maintains its memory. For e.g., when it is switched on again, the ROM stores instructions for the machine to start up.
