What is the difference between standard i386 download and the amd64 download of Ubuntu 11.04? I am currently running the i386 on an amd machine, would my system work better with the amd64 download instead? (my machine was running Windows 7 64bit, but I neglected to look at that prior to installing Ubuntu).
I downloaded and installed Ubuntu from the official site. However, I don't know if I installed the 32-bit or 64-bit version.
In Windows 7 I could right click My Computer and it listed which version it was.
Is there an easy way to check in Ubuntu?
I am on Ubuntu and I did this command:
$ uname -a
Linux slabrams-desktop 2.6.32-29-generic #58-Ubuntu SMP Fri Feb 11 19:00:09 UTC 2011 i686 GNU/Linux
Does it mean I am on 32bit or 64 bit processor?
The reason I am trying to figure this out is that I was getting errors which looked like this:
cannot execute binary file
and from Googling, I thought it was a processor issue. Any ideas?
I have a Core i7 laptop with 4gb ram. In windows, the disadvantage of using the 32bit OS would be that a single app could not use more than 2gb of ram (+ the 2gb shared kernel-space memory) except when setting a boot switch which reduces the amount of shared kernel memory, then it's 3GB max per app.
What disadvantages/limitations would I have in Ubuntu for sticking to the 32bit OS? (If any?) - As I only have 4GB of ram, I can't see why I need to use the 64bit version?
My processor is an Intel Core 2 Duo P8600 (2.40GHz). As far as I know that's a 64-bit processor - I'm a bit confused as the architecture is called AMD 64, is this a generic name given to 64-bit architectures? I've heard of x64 but can't see a release labelled with this.
