UPSC & State PCS Exam | 10 Most Important Questions | Science & Tech

The Union Public Service Commission (UPSC) and State Public Service Commission (PCS) exams are highly competitive and prestigious examinations in India. These exams are conducted to recruit candidates for various administrative positions in the government. Science and Technology is an important section of these exams, and candidates are expected to have a good understanding of the subject. In this article, we will discuss ten important questions related to Science and Technology that can be expected in the UPSC and State PCS exams.

1. What is the difference between a vaccine and an antibiotic?
Vaccines and antibiotics are both used to combat diseases, but they work differently. Vaccines stimulate the immune system to prevent diseases, while antibiotics kill or inhibit the growth of bacteria.

2. What is the significance of the Higgs Boson particle?
The discovery of the Higgs Boson particle in 2012 confirmed the existence of the Higgs field, which gives mass to other particles. This discovery was a crucial milestone in understanding the fundamental building blocks of the universe.

3. What is gene editing and how does it work?
Gene editing is a technique that allows scientists to modify an organism’s DNA. The CRISPR-Cas9 system is the most commonly used gene-editing tool, which uses a molecular scissor-like protein to cut and modify specific genes.

4. What are the applications of artificial intelligence (AI)?
AI has numerous applications in various fields, including healthcare, finance, and transportation. It can be used to diagnose diseases, predict market trends, and develop autonomous vehicles.

5. What is blockchain technology?
Blockchain is a decentralized and transparent digital ledger that records transactions across multiple computers. It is most commonly associated with cryptocurrencies like Bitcoin but has potential applications in various sectors, including supply chain management and voting systems.

6. What are the advantages and disadvantages of renewable energy sources?
Renewable energy sources such as solar and wind have the advantage of being clean and sustainable. However, they can be intermittent and require significant initial investments for infrastructure development.

7. What is the concept of virtual reality (VR)?
Virtual reality is a technology that creates a simulated environment, which can be similar to or completely different from the real world. It is commonly used in gaming, training simulations, and even therapy.

8. What is the difference between 4G and 5G technology?
4G technology provides faster internet speeds compared to its predecessor, 3G. However, 5G technology is expected to be even faster and more reliable, with reduced latency and increased capacity to support the growing demand for internet-connected devices.

9. What are the ethical concerns surrounding artificial intelligence?
AI raises ethical concerns such as privacy invasion, job displacement, and biased decision-making. It is important to develop regulations and guidelines to ensure the responsible and ethical use of AI.

10. What are the potential applications of nanotechnology?
Nanotechnology involves manipulating matter on an atomic and molecular scale. It has applications in medicine, electronics, and materials science, such as targeted drug delivery, miniaturized electronics, and stronger, lighter materials.

In conclusion, Science and Technology is a crucial section of the UPSC and State PCS exams. Understanding key concepts and developments in the field is essential for success in these exams. The ten questions discussed in this article provide a starting point for candidates to prepare for this section and showcase their knowledge in the field of Science and Technology..
