Applications of Data Processing

Study Notes

Commercial data processing involves a large volume of input data, relatively few computational operations, and a large volume of output.
Data analysis is a specialized term used in science or engineering fields, making use of specialized and highly accurate algorithms and statistical calculations.

Proper security algorithms and protocols ensure safe and secure storage of input data and processed information without unauthorized access or changes.
Researchers can use properly processed data to write scholarly materials and use them for educational purposes.
Data processing is applied in healthcare to retrieve information quickly and save lives.
It is also used in evaluating economic and social areas and factors.

Data movement involves the communication of computers with the outside world, making data "accessible" to devices outside the computer.
There are two types of data movement: peripheral and data communications.
Peripheral data movement involves passing data between the computer and I/O devices connected to the computer, such as monitors and keyboards.
Data communications involve data movement over a longer range, typically to smart devices or other computers.

Data processing is the conversion of data into usable and desired form through a predefined sequence of operations, either manually or automatically.
Most data processing is done using computers and other data processing devices, and thus done automatically.
The output or "processed" data can be obtained in various forms, such as image, graph, table, vector file, audio, or charts.

Data centers are key components that enable processing, storage, access, sharing, and analysis of data.
Data in any form and of any type requires processing, including personal information, financial transactions, tax credits, banking details, computational, imagery, and more.

A competitive market for data services has emerged to perform audit, processing operations for companies or organizations collecting data.
Data processing services help businesses comply with applicable laws, follow standard contractual clauses, make data processing agreements, create security documentation, prevent personal data breaches, and act as supervisory authority for the government.
