i686 means that you’re using
32 bit OS.
Go into the terminal and type in.
If your results are similar to the one below, then yours is 64-bit; otherwise, it is 32-bit.

If you have the x86_64 then your machine is 64-bit.
If your results are similar to this one; then you have 32-bit.

Notice the i686 in the code, that means your machine is 32-bit.
Type in the following in the terminal;
It will give you either x86_64, which is 64-bit, or something else, which is 32-bit.
Also referred to as the
P6 microarchitecture, it is the sixth generation Intel x86 microarchitecture, implemented by the Pentium Pro microprocessor that was introduced in November 1995. i686 code is intended to be executed on processors which are compatible with the 32 bit Intel x86 platform, which includes all Intel 32bit x86 processors up to and including the Pentium 4, etc. as well as processors from AMD and other vendors which make compatible 32bit chips.
It just means that you’re running a 32 bit kernel supporting codes compatible with the
i686 processor architecture.
