string buffer is when the data is in RAM, where as video buffer is present in graphics card. string content is transferred to video buffer which in turn is pushed onto display.
This video series deserves so much more attention than it currently has!

Nice explanation of concepts. Please organize these lessons into a Playlist.
nptel.ac.in/courses/106106144/2 refer to this link and you will get all the videos inside a playlist
superb explanation.Thank you so much.Very clearly understood the concept
Kya aap Ethical Hacker hei
Is this good for gate exam
Set the speed at x1.25 while watching these videos !
Sumeet exactly bro😂😂
@JAYADEVAN RAGHAVAN Yup, you're right. Everyone has their own pace. Go with it and learn!
Nice explanation - It's very useful.. Thank you sir
thank you, sir fantastic explanation!!
have you completed this playlist
very nice explanation,loved it
very well explanation and nice concepts
Sir you said video buffer will be used in processing . I have seen string buffer used , and never listened that term . So which one is correct ??
string buffer is when the data is in RAM, where as video buffer is present in graphics card. string content is transferred to video buffer which in turn is pushed onto display.
any notes available?
Very well explained..
I got this ppt how to download this.

Dear sir,
Pls can u send me ur email so pls ,here's my email id (tenukap@gmail.com)
Thank you sir.
Can any one share those slides
pls check the subtitles
xv6 lessgo
1.5x and thank me later!
Boring explanation
