sunos is (was) the BSD version of UNIX that Sun used to supply, now replaced with the SysV offering Solaris. Version numbers? Sorry, try -- don't think there is a current version of sunos anymore, but I'm not a Sun person. Mike

Technically speaking, Solaris is SunOS 5.x. Since the current version of Solaris is 2.8, this is why some people also refer to it as 5.8 - or just Solaris 8.
Due to an AT&T/Sun alliance around 1987, in which AT&T's System V-based UNIX was integrated with Sun's existing BSD version (SunOS 4.x), the original Solaris was a kind of BSD/System V hybrid. SunOS 5 and Solaris 2.5 (which is closer to System V) existed side by side for a while.
I know this because I did the Solaris Admin I course last week ;-)

I can answer this because I'm old enough to have worked with SunOS 
The "uname" output will always display the name "SunOS". However, in common usage, "SunOS" refers to 4.X releases while "Solaris" refers to 5.X releases. When Solaris 2.0 (SunOS 5.0) was released in 1993, the marketing types relabeled SunOS 4 as "Solaris 1". Thus
SunOS = Solaris 1 = SunOS 4
Solaris = Solaris 2 = SunOS 5
Confused?
Seriously, SunOS releases ended, I believe, in 1995. 4.1.4 was the final version (this was marketed as Solaris 1.1, IIRC). By this time, Solaris 2.5 was just about out, and any further development from Sun was for Solaris 2.5 and beyond.
Solaris 2.0 was EXTREMELY buggy, and most of the kinks didn't get worked out until 2.4 was released in 1994. Since then, it's a pretty good OS with a lot of SysV stuff in it. SunOS is more BSD-based, and more primitive. Patching is MUCH easier on Solaris systems. Same goes for device assignments and the like. Most modifications to SunOS require some sort of config or object file hack, followed by a kernel compile. In Solaris, there are commands and scripts for most of these functions.
HTH.

and never any need to recompile the kernel ...
all configurations and changes can happen on the fly ... if you have clever enough hardware you can even add devices on the fly without ever rebooting, finding missing drivers ... etc ...
you can (like most unices now) change ip configurations on the fly, modify all networking protocols, dynamically alter all routes/uses and applications ...
i like solaris, i'm one of the converted!
