It's difficult to definitively say there are only six major areas of technology, as technology is constantly evolving and intersecting. However, a common and widely accepted categorization includes the following six:

1. Information Technology (IT): Focuses on the use of computers and software to manage and process information. This includes areas like software development, data management, networking, cybersecurity, and cloud computing.

2. Biotechnology: Deals with the application of biological processes and organisms to create products and technologies. This encompasses fields like genetic engineering, pharmaceuticals, agriculture, and bioremediation.

3. Nanotechnology: Involves manipulating matter at the atomic and molecular level. This opens up possibilities in medicine, materials science, electronics, and energy production.

4. Energy Technology: Focuses on developing and improving energy sources, including renewable energy (solar, wind, hydro), nuclear energy, and energy storage systems.

5. Manufacturing Technology: Deals with the processes and systems used to produce goods. This includes robotics, automation, advanced manufacturing techniques, and additive manufacturing (3D printing).

6. Transportation Technology: Focuses on improving the movement of people and goods. This includes areas like electric vehicles, autonomous vehicles, aerospace engineering, and transportation infrastructure.

It's important to note that these areas often overlap and interact, making it challenging to rigidly separate them. For example, biotechnology relies heavily on IT for data analysis and processing, while manufacturing increasingly incorporates robotics and automation technologies.
