PROCESSING MODES

Processing involves accepting data and converting it into output or information.

What is processing?

Processing is completed using the following methods:

Batch processing (offline processing): occurs when data collected over a period of time then grouped together and processed at a certain point, such as weekly or monthly. Examples utility bills

and salary

Online Processing: is the method for processing data in which the data is collected and processed immediately. The user can interact directly with the computer at any time and the data is updated right away (however, there is still a slight delay). Examples: ATM machines,

online games, flight reservations.

Real-time Processing: is the method for inputting, processing and outputting data continuously, and is used to control activities as they happen; however, data is processed in a small time period.Examples: Example flight simulation – the data needs to reach user as quickly as possible so they can react accordingly.

Time-sharing: is the method of processing that allows many users to use a computer system simultaneously. This is mainly used in earlier mainframe computers.
