You can use either a 32bit or 64bit operating system (OS) for 4GB of RAM. 4GB of memory is the limit a 32bit OS can handle, this includes any memory that your graphics card has, so your computer may recognise only 3.5GB of RAM if you have a 512MB GPU. You will need a 64bit os that will use all of the ram.
6GB memory will hold more things than a 4GB item
The amount of memory (RAM) Google SketchUp or any other design tool out there is using, is relative to the complexity of the model you are working on. Ideally, the more the better, but that is also Operating system (OS) limited: - Sketchup is a 32bit application. - Windows 32bit cannot address (use) more than 3GB or RAM (3.2GB, but w/e). Having more than 3GB (or 4GB, still you cannot use all of it) in a 32bit Windows Machine is pointless. Macs work a bit differently, so even 32bit OS can address more than that. - Individual Applications are not allowed by 32bit Windows to use address more than 2GB of RAM. - Windows 64bit, by default, run 32bit Applications (like Sketchup) with the same 2GB limitation, only that can be "patched", so each can use up to 4GB (64bit apps do not have such limiations, but SU is not one of them yet). You can follow the guide in this site to do so: http://maketecheasier.com/increase-memory-limit-for-32-bit-applications-in-windows-64-bit-os/2011/08/13
The 4gb has much more memory. About 16 times as much.
32-bit OS can only hold up to 4GB of memory. 64-bit OS can hold up to 1TB of memory, most motherboards can only hold from 12 to 16GB of memory.
Address space refers to how much memory you could potentially talk to so for instance a 32bit processor has a 32 bit addres space i.e. 2^32 = 2 x 2 x 2 ..... 32 times which equals 4294967296 - this is 4Gigabytes. The physical memory is how much memory you have installed so this could be anything up to 4GB. Any memory above 4GB would no be able to be used by the processor.

There are 1000megabytes in 1Gigabyte.So 4GB is the bigger amount.
4 GB of memory should be more than enough, unless you're doing some heavy picture editing or gaming.
It depends on context. 4GB is actually all the memory that Windows XP can handle (there's a special 64-bit edition that can use more than 4GB). However, it's not a huge amount of memory for a video camera (it's not horrible, though; it represents maybe an hour of standard definition video).
The Sony PCM-D50 comes with 4GB of built-in memory, but the Memory Stick Pro-HG Duo Slot allows you to add up to 4GB more of memory.
The only difference is the memory size, with the 4gb having more storage space.
