Rather than give memory modules catchy names, the industry refers to modules by their specifications. But if you don't know a lot about memory, the numbers can be confusing. Here's a short summary of the most popular types of memory and what the numbers refer to.

Generations of memory explained
For double-data-rate memory, the higher the number, the faster the memory and higher bandwidth. Occasionally DDR memory is referred to by a "friendly name" like "DDR3-1066" or "DDR4-4000." When written this way, the number after "DDR" represents the generation. The number after the generation refers to the component's data transfer rate per second (/s). When referenced by the industry name, the numbers that follow "PC" and the generation refer to the total bandwidth of the module.
