Segmented, Paged and Virtual Memory

Memory management is one of the main functions of an operating system. This video is an overview of the paged and segmented memory management systems. It describes how a segmented memory management system employs segments of different sizes, which can result in fragmented free space and prevent large processes from accessing the memory very often. This is compared with a paged memory management system in which small equal sized pages are used instead. Concepts such as logical and physical memory are explained, as well as the use of secondary storage to provide virtual memory.

He speaks so passionately and eloquently. He was born to be an educator.

Love how he emphasizes on key words on a phrase. This video is amazing.

Lifesaver. Was trying to understand this from my lecturer for far too long, this saved me hours. Great concise explanation.

Last time I saw this video was 3 years ago. Whenever I want to refresh my paged/segmented/virtual memory knowledge, I skip all other videos on it and come straight to this.

0% bullshit
100% to the point/visualized explanation

Saved me 2 hours of rewatching my lecture on this. Thank you for such great content.

my teacher just said:
paging is dividing the memory into equal spaces..
and then i had to figure out what happens from this amazing vid...
it's really fun when you understand how it works not just telling me stuff to memorize like a memory card

your videos are a gem! thank you for this. i am going to be going through them over break - UCSD student here.

That is the best video I have ever seen on the internet about segmentation, paging and swapping operations. Explaining all the concepts on the same video allows us to understand the whole concept of memory management. Thank you so much for your help.

Thank you for this! I've read and watched several articles and videos but none of them were as detailed and easy to understand as this

[vriMz]

I swear you're helping me to pass my exam this friday.. First the negative binary addition and now paging. Thanks alot

[celsiusfahrenheit]

you should be the only one teaching this, most eveyone else in billions of google searches could not clearly explain the difference between logical, physicla and virtual memory, i was very confused betweeen logical and virtual, now with one image I totally get it.

Thank you for this amazing video, I've spent the whole day today trying to understand my lectures, this helped clear things up so much!

[mr_ant_]

You have such an amazing ability to simplify complex topics. Thank you

[hongkyulee]

Very clear and concise! Thank you for the good explanation!

[akhileshbhalerao]

It's been a long time i wasn't clear with the concept and after watching this video and many more videos of yours in this playlist.. All became crystal clear.. Thanks a lot.. 👍🏻

I needed a refresher on segmented vs paged memory, and this was fantastic and concise. Wish this video was around when I learned about it the first time lol

[oliverbeck]

such a great voice, tone with a clear explanation, awesome...

[vephovandenberg]

Currently, I am learning how do operating systems work. This video is super helpful. Thank you so much.

[taubenangriff]

exam in 2 days, crunching learning hard. what a great video to get into the basics fast.

1. You sound like Daniel from the game Amnesia : The dark descent.
2. Awesome. Hours of reading in 7 minutes... Why I just cant understand why cant people explain something easily with examples like this, we would have conquered all planets by now with educators like you. I start to think that we make things sound difficult on purpose... Thank you!
