How Can I Learn the Basics?

I am new to cyber security and find some topics difficult to understand. While looking for study ideas, I found ethical hacking assignment help. I want to learn the basic ideas in a safe and proper way and write my own assignment. What beginner topics should I understand first? Are simple labs, diagrams, or videos helpful for learning? I would really like suggestions from students who started with little knowledge. What resources or study methods helped you understand the basics?
