From RAM to Flash: How Computers Actually Remember Things
In short: Ever wonder what happens inside your machine when you open an app? This video maps out the entire hierarchy of computer memory, from the lightning-fast registers in your CPU to the long-term storage on your SSD.
The video provides a comprehensive overview of how different memory types balance speed and persistence. It begins by distinguishing between DRAM and SRAM, then explores how CPU cache and registers provide the high-speed access necessary for processor performance.
You will also learn about specialized hardware like VRAM for graphics cards, as well as software-driven solutions like virtual memory. Finally, it traces the evolution of ROM—from early PROM and EPROM to modern EEPROM and the flash memory used in today's USB drives and SSDs.
