What are TRIGGER EVENTS in Salesforce?

Using events we specify when our block of code inside TRIGGER should execute. The events which we can specify are as below:

·       Before insert

·       After insert

·       Before update

·       After update

·       Before delete

·       After delete

·       After undelete

For example, the following code defines a trigger for the before insert and before update events on the Contact object:

trigger myAccountTrigger on Contact (before insert, before update) {

    // Your code here

}
