A:Answer Yes, this is a 64 bit architecture.
Built-in graphics is Radeon Graphics with 512 MB, but there is also a NVIDA GeForce GTX 1650 graphics card with it's own 4GB of memory.
System already has 256 GB M.2 card install and it has a separate slot to add SATA SSD card (easy for user to add SATA SSD, check out youtube videos - hardest part is to crack open case - use a guitar pick (not screwdriver) to avoid marring the plastic case).
System comes with a single 8GB 260 Pin DDR4 3200 SO DIMM, just add another 8GB DDR4 3200 SO DIMM chip to get 16 GB (or you could add 16GB chips to get 32 GB)
