Technology is the application of conceptual knowledge to achieve practical goals, whether in science or in everyday life. It includes both tangible tools such as utensils and machines, and intangible technologies like software. It also refers to the processes and systems of converting natural resources into useful forms.
Throughout history, humans have used technology to transform their environment. From the prehistoric discovery of fire to recent advances in communication and transportation, human technological developments have increased food availability, lowered travel distances, and made it possible for humans to interact with their environments on a global scale. However, not all of the uses of technology have been positive. Humans have also used technology to develop weapons of increasing destructive power, from clubs to nuclear bombs.
Modern technology is built on previous technological achievements, and each new advancement builds upon the successes of the past. The development of the computer is an example of this pattern. While the computer may seem to be a completely new invention, it is actually built upon earlier technologies such as the vacuum tube and telegraph.
Computer technology is a major industry that provides many jobs and opportunities for people around the world. It is involved in a variety of tasks, from providing access to information and entertainment to improving educational instruction and business operations. People in this field often specialize in a particular area of the field. For example, a person who is involved in the creation of new computer hardware is known as an engineer, while someone who works with software applications is called an IT professional.
Technological progress is driven by the desire to meet a particular need. The first step is identifying the need, which is usually done through observation and research. Once the need is identified, the next step is finding a way to solve the problem using existing technology. This can be done by looking for ways to improve existing technology, or by creating new technologies to meet the need.
One of the most important aspects of technology is its combinatorial nature. Arthur explains that every technology is comprised of other technologies, which are themselves composed of other technologies. For example, a jet engine is made up of technologies such as a compressor and turbine. These are in turn composed of other technologies such as an anti-stall system and a cooling system.
The ability to combine different types of technology has also been instrumental in accelerating the rate of technological progress. In the early 1900s, scientists discovered how to fit the parts that make electronic products work onto tiny chips called integrated circuits. This allowed them to create much smaller devices such as personal computers, digital cameras, and cellular telephones.
There are several paths to a career in tech, including a bachelor’s degree and online learning courses. Some schools, such as SNHU, offer degree programs that allow students to work with the latest in technology and build a portfolio of their best work that they can use to land a job.
