Question
Which type of memory requires frequent refreshing to retain
data?Solution
DRAM (Dynamic RAM) stores data using capacitors that gradually lose charge, requiring constant refreshing to maintain the stored information. It is widely used in personal computers, workstations, and servers due to its cost-effectiveness and high storage density.
In contrast, SRAM (Static RAM) does not require refreshing and is faster but more expensive.
