The Be File System (BFS) is the native file system for the BeOS.In the Linux kernel, it is referred to as "BeFS" to avoid confusion with Boot File System.. BFS was developed by Dominic Giampaolo and Cyril Meurillon over a ten-month period, starting in September 1996, [2] to provide BeOS with a modern 64-bit-capable journaling file system. [3]
A 64-bit processor performs best with 64-bit software. A 64-bit processor may have backward compatibility, allowing it to run 32-bit application software for the 32-bit version of its instruction set, and may also support running 32-bit operating systems for the 32-bit version of its instruction set.
AMD64 (also variously referred to by AMD in their literature and documentation as “AMD 64-bit Technology” and “AMD x86-64 Architecture”) was created as an alternative to the radically different IA-64 architecture designed by Intel and Hewlett-Packard, which was backward-incompatible with IA-32, the 32-bit version of the x86 architecture.
Its key services include handling byte order differences, such as between a little-endian host and big-endian target, correct conversion between 32-bit and 64-bit data, and details of address arithmetic specified by relocation entries. BFD [2] library can be logically divided into two parts. The front-end and the back-end.
Microsoft Windows, for example, designates its 32-bit versions as "x86" and 64-bit versions as "x64", while installation files of 64-bit Windows versions are required to be placed into a directory called "AMD64". [20] In 2023, Intel proposed a major change to the architecture referred to as X86S (formerly known as X86-S). The S in X86S stood ...

The problem disappeared slowly with PCs and workstations moving completely to 64-bit computing. Microsoft Windows Server 2008 has been the last server version to be shipped in 32-bit. [7] Redhat Enterprise Linux 7 was published in 2014 only as a 64-bit operating system. [8] Ubuntu Linux stopped delivering a 32-bit variant in 2019. [9]
