What type of memory configuration is characterized by using four modules and four slots?

Quad-Channel Memory refers to a memory configuration that utilizes four memory modules and supports four corresponding memory slots on the motherboard. This configuration allows for a wider data path, effectively increasing the amount of data that can be processed between the memory and the memory controller at any given time. As a result, Quad-Channel Memory can enhance the performance of a system by improving bandwidth, especially in memory-intensive applications such as video editing, 3D rendering, and high-performance gaming.

In contrast to the other configurations, Dual-Channel Memory uses two modules, Single-Channel Memory uses one module, and Triple-Channel Memory employs three modules. Each of these configurations has its own bandwidth advantages but does not achieve the same level of performance enhancement as Quad-Channel Memory when it comes to data throughput. The presence of four modules and four slots specifically indicates that the setup is optimized for maximum data transfer, which is why Quad-Channel Memory is the correct answer.
