My computer's information:
Processor Intel Pentium 4 3.00ghz (2CPU)
2046MB RAM
Can I install Ubuntu 12.04? Or will it be slow ?
These are the minimum requirements taken directly from the ubuntu system requirements page
700 MHz processor (about Intel Celeron or better)
512 MiB RAM (system memory)
5 GB of hard-drive space (or USB stick, memory card or external drive but see LiveCD for an alternative approach)
VGA capable of 1024x768 screen resolution
Either a CD/DVD drive or a USB port for the installer media
Internet access is helpful
Your machine should definitely be able to run ubuntu.
You can also always use an ubuntu live cd to try out ubuntu and see if it suits you. =)
