Explanation

Blu-ray pairs with optical laser storage, SSD with electron-based chips, ROM with read-only memory, and RAM with volatile working memory.

A Blu-ray disc uses blue-violet laser light for very high optical capacity.

An SSD stores data in a microchip with no moving parts.

ROM is non-volatile memory that can be read but not written to.

RAM is volatile memory holding data and programs currently in use.

Volatile memory loses its contents once power is switched off.
