Understanding Computer Memory

The video explores the role of memory in both humans and computers, highlighting how computers use bits stored in memory cells to process data. It explains the differences between short-term and long-term memory, focusing on RAM and its types, DRAM and SRAM. The video also covers long-term storage options like magnetic, optical, and solid-state drives, discussing their speed, cost, and reliability. Finally, it addresses the challenges of memory degradation and the ongoing research to improve memory technology.
