Ember {{component}} custom component

I am new to Ember and noticed the following code in my Handlebars.

{{component sec.myCompRef secInfo=sec fields=model.myMap}}

Does Ember have some helper like {{component}} ? If yes, how does it work ?

I have generally seen custom helper

{{my-helper }}

but that has the same name component hbs/js backing it ?

But I am not aware of {{component}} helper
