RAM slot, socket, or a memory slot is a gap on your computer’s motherboard where you can insert your RAM. Once you know that, it will be easy to figure out why RAM slots are also different from one another. To understand the different types of RAM slots, we need to look at what types of RAM modules exist and how they differ. Each slot will fit a certain module to at, which means that certain types of modules just won’t fit. When you talk about the random access memory (RAM) of your device, you’re actually talking about two parts – your RAM module and your RAM slots.
