Hi Ashok,

Apex Class : Apex class is class where you can write your logic and then you can use this class with many componets like.. With VFP, in trigger , components.
Apex class are used to execute our logic we need to call class method or logic and we can use.

Apex Trigger: A trigger is Apex code that executes before or after the following types of operations: insert. update. delete. In trigger you can write logic but you can't create instace of the trigger becasue trigger is place where a code can be run on any event, we can use class in trigger but we can't use trigger in class.

Triggers are like event listeners in Salesforce - they run immediately when a specific event happens. Possible events are before / after combined with insert / update / delete / etc etc.

Classes are blocks of code that are only run when specifically called upon, unlike triggers which automatically run whenever a certain event happens. You can call classes from triggers.

Trigger : Can write logic , but you cant create instance of the trigger because trigger is a place wher code can run based on events.
