DRAM modules, or Dynamic Random Access Memory modules, are essential components in computers and other electronic devices. They store data temporarily, allowing the processor to access information quickly while performing tasks. DRAM is volatile memory, meaning it loses its data when the power is turned off. These modules come in various forms, such as DIMMs (Dual In-line Memory Modules) for desktops and SO-DIMMs (Small Outline DIMMs) for laptops. The capacity and speed of DRAM modules can significantly impact a device's performance, making them crucial for multitasking and running demanding applications.
