A 'batch' is defined as a set of transactions that have been packaged and are ready for final settlement. The 'batch' process is typically configured to happen once daily at a predetermined time (oftentimes this is set to the same time as the system's 'end of day' time to keep reconciliation less challenging).

I know only this much about batches.. If any one knows more about the batch then come n share here

if you are taking about computer stuff .. then.. In a computer, a batch job is a program that is assigned to the computer to run without further user interaction.... its a collection of commands ... extension of that file is .bat

Instead of processing transactions and updating a system real-time as the transactions occur, they simply store them up and run them as a big group at some later time.
