| The faster chip also requires that the operating system and applications that run on top of it be recompiled for 64-bit processing. |
| It allows these applications to run, without recompilation, under a 64-bit operating system in long mode. |
| In 1991, Torvalds began experimenting with a rudimentary operating system kernel. |
| But it always lacked focus, initially positioning itself as a intelligent agent software and handheld operating system developer. |
| The code is specific to this operating system and will not run successfully on other operating systems. |
| And it assumes that applications are well-behaved enough to use the protection facilities in the operating system. |
