How Information technology work as the capability to electronically input process, store, and output, transmit, and receive data and information? Explain with the help of a suitable example
Data procesing refers to the transformating raw data into meaningful output.
Data can be done manually using a pen and paper, mechanically using simple devices eg typewritter or electronically using modern dat processing toolseg computers
Data collection involves getting the data/facts needed for processing from the point of its origin to the computer
Data Input- the collected data is converted into machine-readable form by an input device, and send into the machine.
Processing is the transformation of the input data to a more meaningful form (information) in the CPU
Output is the production of the required information, which may be input in future.
Data processing methods
1. Manual Data Processing
In manual data processing, data is processed manually without using any machine or tool to get required results. In manual data processing, all the calculations and logical operations are performed manually on the data. Similarly, data is transferred manually from one place to another. This method of data processing is very slow and errors may occur in the output. Mostly, is processed manually in many small business firms as well as government offices & institutions. In an educational institute, for example, marks sheets, fee receipts, and other financial calculations (or transactions) are performed by hand. This method is avoided as far as possible because of the very high probability of error, labor intensive and very time consuming. This type of data processing forms the very primitive stage when technology was not available or it was not affordable. With the advancement in technology the dependency on manual methods has drastically decreased.
