What is a DIMM?

A DIMM, or Dual Inline Memory Module, is a type of computer memory module that contains RAM (random access memory) used in computers and other devices. The term "dual inline" refers to the fact that it has separate electrical contacts on each side of the module, allowing data to be transmitted more efficiently compared to older single inline memory modules (SIMMs). DIMMs are widely used for their ability to improve performance in terms of speed and bandwidth, as they support wider data paths.

Their design facilitates the installation of multiple memory chips on both sides of the module, which not only maximizes the memory capacity within a limited space but also enhances the capability of the memory to operate at higher speeds. This makes DIMMs a critical component in the overall performance of a computer system.

The other options reflect terms that either do not exist in the context of memory modules or refer to incorrect concepts related to memory architecture.
