When purchasing a new Server, Workstation or PC to support an expansion card one of the most important things to determine is what type of slot does the motherboard have. There are 3 types of slots that have been used for over the years: ISA, PCI, and PCI Express (PCIe). These are also the most common types of slots that computer motherboards have had for expansion cards. Let's take a look at each of these:
Check your used and available RAM. You'll find the currently used RAM in the bottom-left corner of the screen, while your Android's total available RAM (e.g., RAM not reserved for use by the system) is in the bottom-right corner. Of course open the casing and take a look is not much effort, but why I have to do 'dirty work' if there is an easier way to find out in no time? So, here is this WMIC command I used to find out the number of RAM slot in used and the size of each RAM module in the memory slots. 1) Open the Command Prompt window and execute the following sample.

ISA Slots
The ISA Slots are shown in Green in image to the right. This is the oldest slot type that is still available today. Computers with ISA slots are no longer available from major computer manufacturers, Ram PC Systems still sells industrial class systems with ISA slots.
PCI Slots
PCI slots were the replacment for ISA slots. The PCI Slots are shown in the Red box in the image. PCI slots come in several different versions including 5 volt and 3.3 volt slots, and 32-bit and 64-bit PCI-X slots. PCI slots are going away as well but are still available from some major computer manufacturers but they usually only offer one PCI slot. Ram PC Systems has several different systems available with 2 or more PCI slots.
PCI Express Slots
PCI Express slots are the replacement for PCI slots, and also AGP (used only for video cards). PCI Express, also labeled as PCIe come in numerous bus widths labeled: x1, x2, x4, x8, and x16.
