8 Different Types Of Technology In 2024 [With Examples]

Technology is about more than just gadgets and gizmos. It has a very broad and deep definition.

The term “technology” comes from the Greek word “teckne” (which relates to art or craft) and “logia” (which relates to study). The combination of these two words, teknologia, means systematic treatment.

Over the past two centuries, the use of the term “technology” has changed significantly. By the 1940s, “technology” referred not only to the study of industrial arts, but it includes all machines, tools, instruments, weapons, communicating and transporting devices, as well as the skills by which humans build and use them.

More broadly, technology refers to tools, machines, and a collection of techniques that may be utilized to solve real-world problems. The tools and machines can be as simple as a nail pin or as complex as a particle accelerator or space station. Also, they need not be physical; virtual technology, such as software and cloud services, fall under this definition of technology.

In a broader way, technology is a means to fulfill a human purpose.

Since technology can be so simple or extremely complex, it can be categorized into different groups. Below, we have explained all different types of technology with modern examples.

8. Materials Technology

When changes occur in the nucleus of atoms, massive amounts of energy are released. Nuclear technology involves all techniques that manipulate/control such changes in the nucleus of some specific elements and transform them into usable energy.

It is extensively used in nuclear power plants to produce electricity. Nuclear power is an efficient and clean way of boiling water to create steam, which turns turbines to generate electricity.

These plants use nuclear elements, such as uranium or plutonium, to generate electricity through a reaction called fission (in which the nucleus of an atom splits into two or more smaller nuclei).

Most plants use small, hard uranium pellets as fuel. A single pellet, about the size of a fingertip, contains as much energy as 17,000 cubic feet of natural gas, 3 barrels of oil, and 1 ton of coal. More specifically, the fission of 1 kilogram of Uranium-235 releases nearly 18.5 million kilowatt-hours of heat.

Nuclear elements can be a reliable, long-term source of electricity in deep space missions. Spacecraft use nuclear batteries to operate unattended for years. Voyager 1 and Voyager 2, for example, launched in 1977 to study the outer solar system, are still transmitting data today.
