Which Windows technology increases system performance by using flash memory?

Direct Memory Access (DMA) allows hardware devices to access system memory directly without CPU intervention but does not involve using flash memory for performance caching.

File compression reduces the storage space files occupy on a disk but does not use flash memory to directly increase system operating performance.

Connect Now is a feature primarily used for establishing wireless network connections and is unrelated to using flash memory for system performance enhancement.

ReadyBoost enhances system responsiveness by caching frequently accessed disk data onto a faster flash memory device. This allows the system to retrieve information more quickly than from a traditional hard drive, particularly benefiting systems with limited RAM.
