Not since the 70s
In a 32-bit system, there are 4 bytes.
For a 32-bit Operating system: 4 GBFor a 64-bit Operating system: 128 GB
up to 4 gigs
Way to many (:
all pointers are 4 bytes in 32 bit system
Yes!
There is no such thing as 14-bit byte addressable memory. There IS, however, 16-bit byte addressable memory, which I hope is what you meant. In that case, you simply divide 16 by 4 to get 16/4 = 4 nibbles. If you did in fact mean 14-bit address, then it would be 14/4 = 3.5 nibbles
Yes, if the PC have the minimum required hardware GTA 4 will work fine on a W7 64-bit operating system.
You can upgrade it to a maximum of 4 GB, and it requires a 64 bit operating system.
A 64-bit operating system can directly address more memory. This makes it "better" if you have more memory than can be addressed in 32 bits ... 4 GB. If you have 4 GB of RAM or less, there's essentially no difference, and the 32 bit system may even be slightly faster.
Yes.
It can do but it is really the other way around. A 32-bit operating system can work with a 64-bit processor. However, if the processor doesn't have a "soft" switching mode, you will have to manually switch the 64-bit processor to 32-bit mode via the CMOS setup. Ideally you should install a 64-bit operating system and leave the processor in 64-bit mode. This will then allow you to run 32-bit programs and 64-bit programs side-by-side.
