Which type of memory module requires installation of banks in pairs?

The correct response is based on the requirement for paired installation of memory modules in certain configurations, often referred to as dual-channel architecture. This setup allows for improved memory performance by doubling the available data paths between the memory controller and the memory itself. In this mode, memory modules must be installed in pairs to fully utilize the potential bandwidth and achieve higher memory throughput.

When two identical memory modules are installed in corresponding slots on the motherboard, they work in tandem, effectively providing twice the data bandwidth compared to a single module. This is particularly beneficial in systems that require high memory bandwidth, such as gaming or graphic design setups.

The other terms provided in the choices do not specifically denote memory modules that require paired installation. Single bank memory modules refer to the architecture of the memory itself, while RAM is a general term for volatile storage used for temporary data retention. Disk cache involves a different type of memory that is used to speed up data transfer between the storage and CPU but does not relate to the physical pairing of memory modules. Thus, the correct choice effectively encapsulates the requirement for the memory module’s installation configuration.
