There are 3 important stages in this processing they are, Input It is the series of steps for extracting information from raw data. This processing cycle is common to both manual and electronic processing. As soon as he inserts the card and enters balance, he wants to draw along with ATM pin, the machine processes the transaction and updated his bank account balance online within a few seconds. For example, a person wants to draw a certain amount from his account using an ATM. It is a continuous process, which responds within seconds when the data input is given it gets processed and provides desired output data. The best example for electronic data processing is an ATM card, which is embedded with an electronic chip. It processes the raw data through computers and programs using electronic communication. It is also called as information services or systems. Hence with this disadvantage, more advance tools have come where processing work is done automatically. The main disadvantage is that manual processing requires high labor costs, high time consumption, more errors, etc. Like for example manually writing or calculating a report manually and accurately is manual processing, manually verifying marks sheet, financial calculation, etc. The data which is processed manually by human actions that are without using any tool is manual processing. There are three types of data processing, they are Manual Data Processing The basic function of this processing is validation, sorting, summarization, aggregation, analysis, reporting, classification. For example, If we purchase an item in a departmental store they provide us bill after purchasing, where the bill contains all the data items information like item details, customer name, phone number, address, time, bill amount, amount paid, tax, etc, all these put together forms an information, where this information is process form of data. The raw data like the number of students in a class, examination results, address, etc, which is given as input to the processor which uses certain procedures to manipulate the raw data and processes it to provide desired meaningful output. ![]() The process of converting raw data using a medium like manual or automatic tools into meaningful output information is called data processing.
