Hello Avnish,
Trigger.New is simply a list of the records being processed by the trigger, so if all you need to do is loop through them then you can use that. It returns a list which is ordered. Suppose you have a custom object Custom_obj__c then Trigger.New is a list represented as List<Custom_obj__c>.
Trigger.newMap just allows you to target specific records by Id should you not need to process everything, or if you need to map other records back to these. It returns a map which is unordered. Trigger.newMap is a map represented as map<Id, Custom_obj__c>.

Hi,
To understand it more simple -
Trigger.new - it return the list of sobject's records.
Trigger.newMap - It returns the map of Id vs sobject record.
Hope it helps.
