[CentOs]How to find out information about the Kernal

As Software Engineers, you may come across situations of working on different Operating Systems. When you get a task of installing different software to a newly setup operating system, which is not the operating system you used to work on, you have to learn new things. So I had, and it was with CentOS, So I am here to share the things I have learnt from playing with CentOS with you. :)

What is CentOS?

Do you know about this OS? This was the first time I worked with CentOS. The name is abbreviated from "Community Enterprise Operating System". And it is a community-supported Linux distribution for enterprise class. Simply it is kind of a compatible version of Read Hat Enterprise Linux(RHEL). 

The very first thing I wanted to do was to know about the OS. Since it was a separate server, I had to use SSH client Putty for logged to the server. Then I wanted to check the information of the installed OS. And what I have found out and checked it out as follows.
