Determine Kernel Architecture on Linux

Usually, when download an app, you need to select between 32bit and 64bit version. It needs to be compatible with your Linux Kernel Architecture. Here is how to find what version you have:

Open Terminal (Ctrl + Alt + T) and enter the following command:

uname -m

example output:

x86_64

which means 64-bit version of the x86 processor architecture. And when download an app, we need to select 64bit version.
