How to Check if you Have a 32-Bit or 64-Bit Fedora
Fedora is an open source variant of the Linux operating system. Fedora is released as both 32-bit and 64-bit versions. A 32-bit Fedora version supports up to 4 gigabytes of computer memory, whereas the 64-bit operating system recognizes a virtually unlimited amount of memory. The Linux command “uname” allows you to get information about your Fedora computer, including the version of the operating system.
Log in to a user account in Fedora Linux.
Right-click on the desktop and click "Terminal." This will open the Fedora command prompt window.
Type the command "uname -i" and press the "Enter" key on the keyboard.
Read the command output; "i386" means the 32-bit Fedora, while "x86_64" indicates the 64-bit version.
