Computer Memory as a section of Computer Hardware. Computer components, architecture, memory, and storage mechanisms. Consumer product identities remain in Consumer Tech.
Test your knowledge with these top questions!
Which repeated activity gradually wears out flash memory cells?
Storage controllers spread new writes across different cells so one busy area does not wear out first.
Which company developed flash memory through the work of engineer Fujio Masuoka?
The name refers to erasing memory all at once, like the sudden burst of a camera flash.
What can you do with a full flash memory card to make room for new photos?
Deleting photos lets the camera reuse storage space without replacing the card, unlike a roll of exposed film.
What kind of memory stores photos on a digital camera's SD card?
An SD card has no moving parts, which helps it withstand the bumps of everyday camera use.
Which memory type is an erasable form of read-only memory used in USB drives?
Flash memory grew out of erasable read-only designs, so it keeps files without power yet allows rewriting.
How does read-only memory differ from random-access memory?
Random-access memory loses its contents without power, while read-only memory holds its contents.
What do DDR4 and DDR5 modules supply as a computer's main DRAM?
DDR modules plug into motherboard slots and move data twice per clock cycle to feed the processor.
Which fast processor memory is typically built from Static RAM?
Processor caches use Static RAM because it answers in a few cycles, keeping the CPU fed with ready data.
Why does DRAM in a computer need constant refreshing?
Each DRAM cell leaks its tiny electric charge, so the controller rewrites the data thousands of times per second.
How does paging organize virtual memory for the operating system?
These fixed-size pages let the system move only the needed chunks between RAM and disk.
