When editing a video, working a cad design or playing a game.

Really anything really being worked on by the cpu is stored in ram, unless there isn't even page then it is stored in a a page file.

[emosun]

effectively yeah the cpu isn't directly interfaced with the storage without passing through something along the way.

[Acid Panda]

some what yes and no (bad answer really)

depending on the program it will vary.

Yes.

 

Information is taken from hard drive/SSD, then stored in the RAM, and if the RAM is full, PAGEFILE is used instead, which is a file creating on your hard drive and used as "ram" but extremely slow compared to ram.

 

If the pagefile is full as well, oldest information in the RAM will be removed to make room.

Ok a so say im editing a video its stored in ram?

yes whatever section of a video you are working on is stored in ram

so the parts of a cad design are loaded into ram to....

if not there would lots of latency.

What ever you do on your copmuter is stored in the RAM. Take off the ram and nothing works. Computer won't even boot. So I guess even POST and OS boot information is stored in the ram at the beginning when you power up the comp  

[Fasauceome]

The real question is: if it's not, then where is it being stored?

also, if it's being stored elsewhere, what's the point of ram?

Cad will work the same as any video game in that it loads whatever information it can depending on how much ram you need or have and will omit whatever is most likely not needed such as section you aren't focusing on

well keep in mind some equipment doesn;t need system ram to do the majority of it's work and will do all of it's storage and processing itself, though these cases are few and far between lol

It's kind of in the name too, ya know, "random access memory" is for, well, access

Only some of it, there's probably a setting in your video editor for how much ram it is allowed to use.

For learning purpose, can you provide an example ?

back in the day when you had a video capture or tv tuner card it would not use software or system ram to do anything.

it would do all of it's own video processing and simply run a program within windows which simply would forward the final information to the video card and key out a section of the screen to show you what it was doing. Which is why systems with only 486 cpu's were able to capture/record/ and play back video without breaking a sweat. 

It could also happen when a videocard did it's own decoding with a proprietary codec which is why you used to not be able to screen cap videos in windows becuase effectively... the system couldn't see the video because the processing wasn't being done within windows

Oh. Yeah that makes total sense.

in theory your cpu is only working on stuff that is in cache.

 

but yes, sensibly you wouldnt ever have a workload working directly on disk, instead *at least* writing blocks of it to ram to process, before returning them to disk.
