Engineering is a vast field with many sub-categories. From software to AI and deep learning to cybersecurity and robotics, it's a constantly evolving field. Engineers design and build the technology we use every day, from websites and apps to hardware and robots. They use concepts like neural networks and machine learning to create smarter, more efficient systems. Quality assurance is also an important aspect of engineering, ensuring that products are reliable and free from defects. Cybersecurity and blockchain are critical for protecting sensitive data, while DevOps helps teams collaborate and deploy software more effectively. Whether it's software development or hardware engineering, engineering is all about problem-solving and innovation.
