Which of the following is a type of memory that is used for storing data in a USB drive? MCQ with Answer and Explanation

Explanation:
SPD is a small EEPROM on a DIMM that stores information about the memory module's size, speed, voltage, and timings, which the BIOS reads to configure the memory controller.

Explanation:
RAM speed is often measured in MHz (cycles per second) and MT/s (megatransfers per second) for DDR modules, where the effective data rate is double the clock frequency.

Explanation:
Blu-ray discs use a blue-violet laser with a shorter wavelength (405 nm) than the red laser used in DVDs (650 nm), allowing smaller pits and more data per area.
