Which one of the following statements is true about flash memory technology?
It has no moving parts and consumes very little power.
To determine which statement about flash memory technology is true, we need to understand some fundamental characteristics of flash memory. Let's evaluate each option:
- Flash memory is a type of non-volatile storage that retains data even when the power is turned off. One of its defining features is that it has no moving parts. As such, this technology is known for consuming very little power, which makes it ideal for use in portable devices. Therefore, the option "It has no moving parts and consumes very little power." accurately describes flash memory technology.
- The statement "It operates using read-write heads and is used to store data." is false regarding flash memory. This description incorrectly relates to traditional hard disk drives, which do have moving parts including read-write heads. Flash memory does not use such mechanics as it relies on electronic circuits to read and write data.
- The option "It has no moving parts and requires a large power supply to operate." is also incorrect. While flash memory indeed has no moving parts, it is designed to be power-efficient and does not require a large power supply.
- Finally, the statement "It operates using read-write heads and consumes very little power." is incorrect as it inaccurately refers to the operations of flash memory. Flash memory does not use read-write heads.
Therefore, the correct answer is:
It has no moving parts and consumes very little power.
