Computer uname -a output

Can anyone please let me know the meaning of output of uname -a ?
I am totally new to unix or linux and just thinking to start learning.
When I run uname -a the output I get is -
"Linux blx28ap01 2.6.18-238.12.1.el5 #1 SMP Sat May 7 20:18:50 EDT 2011 x86_64 x86_64 x86_64 GNU/Linux"

Are you asking if the system you posted the output from is Unix or Linux?

That is Linux...as shown by the output but if I learn UNIX....would I be missing something from LINUX or vice-versa...that's what I wanted to know..

Of course there are many aspects in which Linux and UNIX are differing. Even UNIX is not a single system, but three major commercial UNIX system can be found on many companies servers, which are AIX, HP-UX and Solaris and they differ quite a lot among themselves. But if you are just beginning your adventure with Linux/UNIX it is better to start with Linux, as the basics are very similar and it is much easier to obtain than commercial Unixes.
