Latency

First let's consider latency.

Latency is the time it takes something to go from Udacity to YouTube.

The latency for a hard drive is much worse than the latency for the DRAM memory.

So the latency you can think of as the time to retrieve a value from memory.

You should be able to compute the latency distance.

The latency is much higher than a CPU register.

The latency distance, though, is quite high. It's 2098 kilometers.

So what I've done is, I've adapted Cloudburst so that it embraces the latency and the performers sing into the latency instead of trying to be exactly together.

And the answers that you should have gotten is that a light bulb, the latency distance is approximately 300,000 kilometers for a CPU register, where the latency is less than 0.4 nanoseconds, the equivalent latency distance is 0.12 meters, about 120 centimeters for the DRAM, DRAM is much cheaper.

I've told you the latency is 7 milliseconds. That's a milli, not a nano.

The main things that matter that distinguish the memory that you have is the latency which is the time it takes to get a response.

The cost varies depending on mostly the latency and the amount of memory you can store.

Additionally the long latency of intergalactic networks means he also needs to carefully roll out a new hash.

The latency for a hard drive is about 7 milliseconds, and a millisecond is 1 1000th of a second.

We'll talk about latency more next class in terms of what that means in networks, which is really the same thing.

For this DRAM the latency is about 12 nanoseconds, and as a reminder, a nanosecond is 1 billionth of a second.

Here the latency isn't a big issue compared to the size of the files we're sending, and it's much more important to send larger chunks over than measuring the time it takes a single chunk to go from Udacity to YouTube.

It's time! It's time. It's time.

Time After Time

Now, we've pushed the technology as far as it can go, but there's still less than a second of latency, but in musical terms, that's a lifetime.

Audience Nice time, time

From time to time.

One time! One time!

Time and time again.

Come on! Time, time!

Narrator We can also learn a lot about the internet by measuring our latency to different destinations, and in fact we can also see the hops along the way.

Time, nobody can see time.

Time is. Time has come.'

Our time is their time.

Next time, OK, next time?

One time is one time.

And from time to time

Taking his time this time.
