2. Mechanical Data Processing
Different calculations and processing
are performed using mechanical machines like
calculators etc. The use of mechanical machines
makes data processing easier and less time-
consuming. The chances of errors also become
far less than manual data processing.

4. Real Time Processing
There is a continual input, processThere is a continual input, process
and output of data. Data has to be processed in aand output of data. Data has to be processed in a
small stipulated time period (real time), otherwise itsmall stipulated time period (real time), otherwise it
will create problems for the system.will create problems for the system.
For exampleFor example, when a bank customer withdraws a sum, when a bank customer withdraws a sum
of money from his or her account it is vital that theof money from his or her account it is vital that the
transaction be processed and the account balancetransaction be processed and the account balance
updated as soon as possible, allowing both the bankupdated as soon as possible, allowing both the bank

5. Batch Processing
In a batch processing group of transactionsIn a batch processing group of transactions
collected over a period of time is collected, entered,collected over a period of time is collected, entered,
processed and then the batch results are produced.processed and then the batch results are produced.
Batch processing requires seperate programs forBatch processing requires seperate programs for
input, process and output. It is an efficient way ofinput, process and output. It is an efficient way of
processing high volume of data.processing high volume of data.
