32-Bit or 64-Bit?
To find out whether you have installed a 32-Bit or 64 - Bit System type in the console / Terminal the following command:
- "getconf LONG_BIT"
- Then, the console returns you the corresponding value. (32 or 64)
As an Alternative, the following command works:
- "uname -m"
- Returns the console "i386" or "i686", then you have installed a 32 Bit System.
- "x86_64" or "amd64" indicates a 64-Bit System.
Your Processor Supports 64 Bit?
How, for example, in Windows, on a 64 Bit System a 32 Bit operating system install. In normal operation this is not noticeable, but you can't use the full power of your PC.
- So 64-Bit systems allow, in contrast to 32 Bits more than 4 GB of memory.
- 64 Bit systems can handle larger Integer values, and thus faster calculations.
If your Computer supports 64 Bit, you can see in the console with the command:
- "cat /proc/cpuinfo | grep lm"
- This command gives you information about the installed processor. The Annex "grep lm" looking for values "lm" included. "lm" stands for "Long Mode" and means that the CPU supports 64 Bit.
- If the command values are not displayed, it can handle your CPU is not 64 Bit.
