I was just doing a test. The following question came up:

Question: Which type of computer component has the fastest throughput when accessing data?


Their answer:
Random Access Memory

I say it is the Central Processing Unit. Which answer is right and why?

Well it depends on what type of DATA is being accessed the ROM lache harddrive etc etc

When ACCESSING data? Level 1 cache on a cpu, Then Level 2, Then Level 3(if it has it), then the ram.

Thanks for the useful information bomberboysk. I wonder why they put RAM has the highest throughput when accessing data? The people writing these tests are supposed to have knowledge about how a computer works.

I would imagine as the level 1/2/3 cache is more for repetitive tasks then actual data, you've seen ramdrive programs i assume, you ever see cache-drive programs?

That's because the CPU would suffer greatly if it loses some of it's cache to a cache-drive...

Thats what i was saying

OP, you are correct because of the higher transfer rate.
