128 bit for sure
no
Nope
Yes, a 128-bit graphics card can work in a 64-bit computer, as the bit depth of the graphics card refers to its memory bandwidth and data processing capabilities, not the system architecture. A 64-bit computer can handle 32-bit and 64-bit applications, and it is compatible with various graphics cards regardless of their bit depth. However, to utilize the full potential of the graphics card, the system should have compatible hardware and sufficient power supply.
What's 4 x 32?

128
I think it is safe to believe that it depends on the processor architecture. When you say 128-bit computer, this may mean different things. There is no such thing as an "128 bit computer". The design may allow 128bit core (processor) in which case an int most likely be 128bit. Or it may imply that only the bus is 128 bit. Or both. One may assume that on the 128bit Intel processor when it becomes available , the size of an integer data type will be 128bit IF it has an 128bit core, and not just the bus.
In encryption, a key is the information used to encrypt the data. 128 bit means that the key is 128 bits long (a bit is a single unit, or "bit" of data, either 0 or 1). The longer the key, the more complex the encrypted data becomes. 128 bits is considered a strong key length.

It is possible to remove the 128-bit encryption in Facebook. This can be done by changing the file's proprieties in Window's Explorer.
