Hi Can anyone plz tell me exact diffs b/w linux and solaris and linux and unix?? Thanks sun

Unix is an OS based on Multics (something from the late 60s). There are two variants: BSD and System 5. Almost every version nowadays is based on System 5. FreeBSD is the only BSD version I know of but there may be others. Solaris is Sun's version of Unix. It has different names and different numbers. Solaris 9 = SunOS5.9. Some versions support 32bits only, others support both 32 and 64bits. Solaris only runs on Intels/AMDs and Sun's RISC platforms. Earlier versions of Solaris (pre 1995) were based on BSD. Later versions are based on System5. Linux is a public domain version of Unix. There are several vendors: RedHat, SUSE, etc. Linux runs on Intels/AMDs. AIX (which you didn't ask about) is IBM's version of Unix. Ultrix (which probably no longer exists) is DEC (which became Compaq which became HP)'s version of Unix. HPUX is HP's version of Unix.

Take a look at this bell lab's unix history link: http://www.bell-labs.com/history/unix/

The exact difference is the code that is between machine code and either/and/or interface/application. While in this question they are close or have things in common they are not the same. The way they access resources and output data are very much different. I read it wrong and answer it wrong too. So get off my case you goober.
