00:01
All right, here we go.
00:02
Continuing right along, learning some good old -fashioned computer science.
00:07
We're talking more about time slices and understanding how long it takes to do things like access memory and stuff like that.
00:14
So if we had, say, a 50 millisecond time slice and we had a process that we're going to take eight in order to get the read -right head over the right part of the hard drive, and then another 17 in order to actually rotate it around and get it.
00:31
So that's 25 milliseconds gone right there just trying to access data before actually doing any instructions.
00:38
I mean, we're talking about 50 % right.
00:40
Of our time slice has been dedicated to just going and finding things in memory.
00:44
Well, that is not ideal by any stretch.
00:47
So just to put that in perspective, you know, if we're trying to think about how much time is really lost there, well, i mean, it depends on, you know, what we're capable of executing.
00:58
So let's say we can do 10 instructions in a nanosephysm.
01:02
For example, right? so that means in a million microseconds, sorry, in one microsecond is a million nanoseconds, okay? so in each one of those nanoseconds, we're able to do 10 instructions...
