Science and Technology

The competitive examinations in today’s time put a lot of emphasis on Science and Technology questions, so it is important for aspirants to go through as many Technology GK questions as they can. Knowledge of Science and Technology is essential in modern contemporary society. You must have wondered many times how Science and Technology produce new and innovative products, novel ways of living, and other questions of similar fashion. Postmodern society can be only understood once we have in-depth information about how social, cultural, and material substances influence the creation of new practices, new institutions, and new ways of understanding things. 

The purview of Science is the systematic study of the structure and behaviour of the natural and physical world through experiments and observations. Technology is the application of scientific knowledge obtained for practical purposes. Science and Technology's ultimate goal is national development.

The opening years of the 21st century have witnessed a shift in society to a knowledge-based society. This has brought Science and Technology to the forefront of activities and has found its place in schools, colleges, and competitive exams. There are many questions being asked on current affairs in Science and Technology quizzes in these exams. To prepare you better for many of these exams and ease your burden, we are providing you with many diverse Science and Technology questions in this article, along with their answers and explanations (if needed).
