L1 05 Numbers Everyone Should Know Memory V4

With CPU and Memory, what else do we need?

QUESTION:

It seems like the right combination of CPU and memory can help you quickly load and process data. We could build a single computer with lots of CPUs and a ton of memory. The computer would be incredibly fast.

What are the potential trade offs of creating one computer with a lots of CPUs and memory? Reflect on this, and then click Submit to learn more

ANSWER:

It's true that you could build a computer with a ton of CPU and memory, which is effectively a supercomputer. However, as you'll see in the next video, this approach has its downsides.

L1 06 Memory Efficient Expensive And Ephemeral V1

Beyond the fact that memory is expensive and ephemeral, we'll learn that for most use cases in the industry, memory and CPU aren't the bottleneck. Instead the storage and network, which you'll learn about in the next videos, slow down many tasks you'll work on in the industry.

Limitations of RAM

SOLUTION:

RAM is relatively expensive
Data stored in RAM gets erased when the computer shuts down
