Types of Data Processing

Below are the types of data processing;

1. Manual Data Processing: This is the use of human hands and brains for processing data. For example, when you do calculations without using any calculating machine.

2. Mechanical Data Processing: This is the use of mechanical devices to process data. For example, a teacher using a calculator to calculate students’ results.

3. Electro-Mechanical Data Processing: This is the use of other electronic devices to process data. These devices make use of electricity but they are not computers. For example, a teacher using an electronic calculator to calculate students’ results. Other examples are a sales officer using a cash register machine in the supermarket, and a bank cashier using a counting machine to count money.

4. Electronic Data Processing (EDP): This is mainly the use of computers for data processing. For example, a teacher using Microsoft Excel to process students’ results is simply doing data processing. Also, an accounts clerk using a computer to process staff payroll is doing data processing.
