Ubuntu14.04LTS of difference and Ubuntu14.04

I wrote today in configuring virtual systems management is Ubuntu 14.04, but found support is Ubuntu 14.04 LTS

 

So Baidu a bit of information, 14.04 is the version number , representing the stable version out in 2014, LTS version is ubuntu on behalf of the long-term support version, and will continue to support the release of security patches and critical period.
