Memory & Storage: Crash Course Computer Science

The video explores the evolution of computer memory and storage technologies, from early punch cards to modern solid state drives. It explains the differences between volatile and non-volatile memory, and highlights key developments such as delay line memory, magnetic core memory, and hard disk drives. The video also discusses the concept of memory hierarchy and the transition to optical and solid state storage, emphasizing the exponential decrease in cost and increase in storage capacity over time.

Why is memory hierarchy important in computer architecture?

What are the key differences between optical storage and magnetic storage?

What role do solid-state drives (SSDs) play in modern computing?
