2. What is Batch apex explain with one simple example?

A developer can now employ batch Apex to build complex, long-running processes that run on thousands of records on the 

Force.com platform. Batch Apex operates over small batches of records, covering your entire record set and breaking the processing down to manageable chunks. For example, a developer could build an archiving solution that runs on a nightly basis, looking for records past a certain date and adding them to an archive. Or a developer could build a data cleansing operation that goes through all Accounts and Opportunities on a nightly basis and updates them if necessary, based on custom criteria.

Batch Apex is exposed as an interface that must be implemented by the developer. Batch jobs can be programmatically invoked at run time using Apex.
