Yes, my first programming language was C, but I soon dropped it and moved to C++. David J Malan is an amazing lecturer. He explained numerous concepts in great detail here, but in a way that is easy to digest. It may be a little too easy for coders that are more familiar with computational thinking from using other languages such as Python and Java, but I would still very much recommend this to anyone.
  4. Difference Between Security and Protection: Before reading this, I seriously thought these two methods are the same thing…
  5. Security Attacks: A short but complete video on active and passive security attacks, and types of active security attacks, such as Masquerade, Replay, DDOS, and others!
