What is a memory module?

A memory module refers to a component that consists of memory chips arranged on a circuit board. These modules are specifically designed to easily interface with the motherboard of a computer. They allow for quick access to data by the CPU, acting as temporary storage for the operating system, applications, and currently processed data.

In modern computing, memory modules come in various forms, such as DIMM (for desktops) or SO-DIMM (for laptops). The design of these modules ensures that they can be easily inserted and removed from the motherboard, facilitating upgrades or replacements.

The other options describe devices that are not classified as memory modules. A standalone storage device and a type of hard drive refer to permanent storage solutions, while an external storage solution typically implies any removable media or device that connects externally, such as USB drives or external SSDs. None of these have the same function or construction characteristics as a memory module.
