Memory - RAM
RAM (Random Access Memory) is where data the CPU is working with is temporarily stored. More RAM is generally better, although there are diminishing returns and 32-bit versions of Windows only support a maximum of 4GB. Speed, measured in MHz, is another consideration, but most importantly memory needs to be compatible with your motherboard: it'll either be DDR, DDR2, DDR3 or DDR4. Smaller SODIMM modules for laptops and mini PCs and ECC memory for servers are all available in this category.
DDR4 SDRAM is the fastest and most efficient consumer memory available. It's compatible with Intel's Broadwell-E which run in quad-channel and Kaby Lake & Skylake CPUs which run in dual-channel modes. It is also compatible with AMD's latest RYZEN CPUs running in a dual-channel configuration. The modules found here are designed for Intel Kaby Lake & Skylake, so they're sold in matching kits of two modules for best performance or single modules for a cheap upgrade. These are the high-end kits, with a speed of at least 3,000Hz.

SODIMM memory is smaller than standard modules, and is used in laptops and mini-PCs. As long as you can access your system's memory slots, you can upgrade it. The kits here come in a range of speeds and capacities, so make sure your system is compatible with the memory you choose.
