If a CPU had a voice, this is it.

@AndriyLinnyk

that is the best voice from tutorials I ever heard.

@shayangzang900

This is THE best OS intro I found so far in youtube.

@podmus3307

This and Hardware basics are the only things you need to see to know how computers work. I learned this all at university but often I missed forest for the trees.  These series rounded all the things in my head nicely. I think I'll have to watch every single video on this channel.

@mankindspatience

My eyes were begging me to let them rest, but I had to finish the video. Unreal clarity in your explanations! Most would need 1h to do the same.

@Verses01

When this video started out, I thought it was going to be a sleeping pill. I was wrong, I have a LOT more confidence in what an operating system is and the components of. Thank you, Mr. Will.

@odytrice

Hey Brian, Just seeing this video and I have to say, there is a need for more content like this. Most high level developers don't understand some of these fundamentals and its really important

@voilin

I love this video. I turn it on from time to time just to hear his voice and refresh my knowledge. Thanks Brian

@kokorodokoro

These are fantastic. Clear explanation, dense yet succinct and non-redundant. I am taking notes and rewatching. Finally the mystery of the computer is starting to disentagle!

@briantwill

Oops. At around 20:00, I say that, within a directory, you can have both a file and directory of the same name, e.g. a file named foo and a directory named foo. This is wrong: every file/directory name must be unique within the containing directory.

@kamoroso94

I had my final today in an Operating Systems class and all of this stuff would've been so useful to see earlier.  When I watched this, I was able to follow very well.  It was nice to see the order you presented everything, it had a nice flow to it :3

@lukegriffiths4333

Brian these videos are great.  I've just discovered your channel and I hope I end up watching them all.  It's good to have a theoretical understanding of the things that underlie my own work which is coding in a scripting language.  Keep 'em coming!

@lukegriffiths4333

If you change the speed to 0.5, it gives the illusion that Brian sounds drunk!  Great videos Brian, thanks!

@glueee2621

Best CS video on the Internet. Period.

@mrcobalt124

This man actually sounds like he knows what he is talking about
Unlike most random OSdev tutorials on YouTube

@tomerlevi8598

It feels like I'm connected through the matrix and your voice is like Morpheus injecting information into my head

I like it, subscribed.
thanks champ.

@WindyHellLetsLoose

It’s a really really enjoyable thing to listen to your voice. I mean, the tone and fluency of your voice exaggerate the effect of my study. Thank you!

@Oneworld87

Deep voice is deep.

@coding3438

What a fantastic video. I’ll have to make a point though. Although this video says basics, it’s not for beginners. It’s for those who already know most of these concepts, although not clearly and thoroughly, and can use this video as a guide to strengthen basic concepts. 

Once again, fantastic video!
