What's the difference between Rapid Release and Pulse Updates?

Good day! What is the difference between RapidRelease updates and Pulse updates.

 

I thought it is the same . Pulse updates - every 5 to 15 minutes , Rapid release - how often ?

 

 

I am asking because something happended twice to me . When I submit a sample to Symantec , I sometimes get a reply that they are preparing definitions , already detected by RapidRelease.

 

I update my Norton , including Pulse updates and I thought it should be detected . But it isn't . However , if I download the RapidRelease manual update package and install it , the sample is detected.

 

So , what's the difference ?

 

 

Many thanks and Merry Christamas to all who celebrate!
