The first computer is an older desktop, and is a HP Pavilion a645c. It has a AMD Athlon XP 3200+ (I think 2.2 Ghz), with 434.4 MiB of memory... I'm not sure if that is 32 or 64 bit.
The XP 3200+ is a 32-bit-only processor, so you will need to use the 32-bit version of Ubuntu. I have that exact same chip and it runs Debian Lenny 32-bit (which is what Ubuntu 8.10 is based on) very nicely.
The other computer is a cheap laptop I just bought at Wal-Mart. It is a Acer Aspire 5515 and has a AMD Athlon Processor 2650e (I think 1.6 Ghz) in it. It also has 2.7 GiB of memory. Again is this a 32 or 64 bit capable system??
Thanks to all of you for the help, I'm sorry for the newbie questions!!
The Athlon 2650e is a 64-bit processor, like all processors AMD has made in the last three years or so. You have 3 GB of physical RAM installed on that machine, so it's really up to you whether to install a 32-bit or 64-bit OS. I would probably just say to go with the 64-bit version since it's a tad faster than the 32-bit version and the slightly larger memory usage of the 64-bit version won't be an issue with 3 GB RAM.
Don't worry about asking questions you think are too simple. Even the smartest computer expert out there didn't know anything about computers at one time.
