Linux began its life in mid-1991, and reached 1.0 in 1994.
The current version of the Linux kernel is 2.6, which came to its first release in 2003, though the most up to date 2.6 kernels don't resemble the original 2.6 kernel much. To the point the first two version numbers are pretty meaningless. As for the rest... the third number increments and the kernel gets a feature release every 3 months, which will introduce some new features, change others, and remove some. The fourth number will release frequently, but with no set pattern aside from the patch being "ready." Patch releases are purely for bug fixes.
There are older versions of the kernel available effectively for long term support purposes. They are often considered very stable and will generally only be used on servers and distributions without a very rapid release schedule.
Current stable kernel version: 2.6.38.5.
The Linux kernel which forms the base of Linux started to be developed in 1991 It wasn't until late 1993 when Slackware first appeared that it was in any kind of usable form though - unless you were an uber geek that is. Red Hat Linux 1 appeared in mid 1994 and Debian 1 was released a year later The first Ubuntu (a clone of Debian) didn't get released till 2004
Linus Torvalds in Sept. 1991
The 2.4 version of the Linux kernel was released in 2001.
Mac OS came first, as it was introduced by Apple in 1984. Linux followed, with its first version released in 1991 by Linus Torvalds. DOS, specifically MS-DOS, was released by Microsoft in 1981, making it the second of the three to debut, but after Mac OS. Thus, the chronological order is Mac OS, MS-DOS, and then Linux.
I think it was the Linux kernel. There are many used with Linux now.
The original Linux kernel was written in 1991.
The kernel.
How much old do you mean by old? Well, before Gnome and KDE, there was the Command Line Interface (CLI). MCC Interim Linux was the first linux distribution, released in February 1992 used the CLI.
Yes, Linux is an open source kernel released under the GPL.
Linux was created in 1991 by Linus Torvalds, then a 21-year-old college student in Helsinki.
It was first released November 19, 2006
The first used operating system between MS-DOS and Linux is MS-DOS. MS-DOS, short for Microsoft Disk Operating System, was developed by Microsoft and released in 1981. Linux, on the other hand, was created by Linus Torvalds and released in 1991. Therefore, MS-DOS predates Linux in terms of initial release and usage.
