3 Different Types Of Technology In 2022

By | November 30, 2022

Technology is more than just tools and devices. It has a very broad and deep definition.

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

In the last two centuries, the use of the term “technology” has changed dramatically. In the 1940s, “technology” referred not only to the study of the industrial arts, but included all machines, tools, weapons, communication and transportation devices, as well as abilities that humans build and use.

In more general terms, technology refers to the tools, machines, and set of technologies that can be used to solve real-world problems. Tools and machines can be as simple as a nail or as complex as a particle accelerator or space station. Also, it doesn’t have to be physical; Virtual technology, such as software and cloud services, are included in this definition of technology.

In a broader sense, technology is a means to a human purpose.

Since technology can be very simple or very complex, it can be classified into different groups. Below we explain all the different types of technology with recent examples.

  1. Information Technology

Applications: Multimedia conferencing, eCommerce, cloud computing, online banking, speech recognition, Intrusion Detection System, online advertisement

Today, Information Technology (IT) refers to everything people use computers for. While this field commonly deals with computers and computer networks, it also incorporates other information distribution technologies such as telephones, television, and the Internet.

Many companies now have IT departments for managing computers, creating and administering databases, and ensuring the efficiency and security of business information systems. Recent advances in computer software have enabled businesses to analyse data more precisely to discover hidden patterns and make informed decisions.

In the past decade, tech giants have focused on artificial intelligence and machine learning so that computers can make “human-like” decisions using real-time data. At this point, AI can perform a wide range of tasks far better than humans. For instance, it can

Predict future outcomes based on historical trends

Discover inefficiencies

Automate complicated analytical tasks

Execute plans

Learn and become better

The other revolutionary invention is the blockchain — a specific type of database that stores information in the most secure way. Blockchain technology enhances the security, transparency, and traceability of data shared across a business network.

Quantum computing, which harnesses the phenomena of quantum mechanics, also falls under the IT umbrella. In fact, it is considered the next significant evolutionary milestone in the development of information technology.

  1. Biotechnology

Applications: Use of microorganisms for creating organic products like milk and baking bread, extraction of metals from their ores through the use of living organisms (bio-leaching), production of biological weapons

Biotechnology utilises biological systems and living organisms to develop different products. It covers a wide range of disciplines, from genetics and biochemistry to molecular biology.

Modern biotechnology provides revolutionary techniques and products to combat severe and rare diseases, reduce negative impacts on the environment, use cleaner energy, and have safer and more efficient industrial manufacturing processes.

Based on applications, biotechnology can be categorised into seven types:

Red biotechnology:

involves the development of vaccines and antibodies, artificial organs, diagnostic tests, and regenerative therapies.

Green biotechnology:

is applied to fight pests and nourish crops and strengthen them against harsh weather conditions and microorganisms.

White biotechnology:

consumes fewer resources than conventional processes. It is used to create industrial goods. It involves designing organisms and enzymes to create valuable chemicals or destroy hazardous chemicals.

Blue biotechnology:

exploits sea resources, such as micro-algae, to develop products and industrial applications.

Yellow biotechnology:

focuses on food production. For instance, conducting research to decrease levels of saturated fats in cooking oils.

Gold biotechnology:

uses advanced computational techniques to obtain, store, analyse and separate biological information, particularly related to DNA and amino acid sequences. It plays a crucial role in numerous fields, such as structural genomics, functional genomics, and proteomics.

Gray biotechnology:

addresses environmental issues and focuses on the maintenance of biodiversity and the removal of pollutants.

As of 2021, there are over 250 biotech health care products and vaccines available to patients. More than 14 million farmers worldwide use agricultural biotechnology to enhance yields and minimise damage from pests and insects.

More than 200 bio-refineries have been established in the United States to examine and refine techniques of producing bio-fuels and chemicals from renewable biomass.

  1. Nuclear Technology

Applications: Production of electrical energy, radiotherapy, smoke detectors, sterilisation of disposable products, Radioisotope Thermal Generators used in space missions

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.

Apart from electricity generation, nuclear technology is also used in gun sights, medical radiography, and sterilisation of tools and equipment.
