In this episode of the CyberGizmo we explore Memory Management in Linux (and a few other examples from old out of data Operating Systems.

I adore the historical view of explaining a topic. It makes even things I've known and worked on for years much clearer and based!

[@harryjohnsonperu724]

binge watching this Linux playlist. Thank you DJ for this excellent content!

[@CyberGizmo]

Thank you Harry glad you like it :)

[@gylkag]

Wanted to thank you again for these very informative, well structured and condense videos! Thank you!

[@CyberGizmo]

Welcome Olexi glad you found it useful :)

[@unikkkkkkk]

Great, thanks a lot sir, you are very fluent in spreading this valueable knowledge + it's really enjoying to hear the historical reasons and design decisions behind each component

[@DrZingo_]

Great content as usual. I especially like it when you combine these talks with showing it hans on. Like 'size', 'lsblk' and explaining what it outputs. There is always a couple of new things I get better understanding about.

[@CyberGizmo]

Glad this video helped and yeah I always learned more that way too, its one thing to talk about it, its another to work with it.

[@daxenzo58]

A tip: you can watch series on kaldrostream. I've been using it for watching a lot of movies lately.

[@deaconbraydon1999]

@Dax Enzo Yup, I have been using flixzone} for years myself :)

[@malcolmtitan8602]

@Dax Enzo definitely, have been watching on flixzone} for since december myself =)

[@kyriedustin4619]

@Dax Enzo Yup, have been using Flixzone} for months myself :)

[@soubai]

20:07 TLB stands for Translation Lookaside Buffer. Thanks for the awesome playlist DJ

[@hexearth8258]

Again, learned loads of stuff. Thank you.

[@CyberGizmo]

Thanks Hex Earth

[@emvdl]

Great to watch, FANTASTIC, thank you 👍🇳🇱

[@CyberGizmo]

Thank you Ernst

[@diegonayalazo]

Thanks DJ!

[@guilherme5094]

Another excellent video.

[@CyberGizmo]

Glad you liked it, Felix

[@Remigrator]

Awesome, thanks!!

[@CyberGizmo]

Welcome, Robert

[@EEEEMMMMKKKK]

I would really like to listen to these kind of talks focused on how programs interact with hardware through kernel. Something more programming oriented.

[@bibekkoirala2517]

great video

[@CyberGizmo]

Thanks HexHexByte glad you liked it

[@artyomgevorgyan7167]

Good content. You made my day. Русскоязычные тоже смотрят.

[@CyberGizmo]

welcome Artyom glad you like it

[@UpcycleElectronics]

Where does (peripheral hardware) Direct Memory Access fit into the memory management topology? Thanks for the upload. -Jake

[@CyberGizmo]

Good question, in Linux DMA falls under the I/O management (or filesystem manager) since Linux follows how UNIX did things and I will be covering it when I get to that part of the Linux kernel.

[@EmilNicolaiePerhinschi]

Thanks!

[@subee128]

Thanks

[@harryjohnsonperu724]

Hi DJ , can you make a second part for this video explaining high memory, low memory , kernel virtual address, user virtual address etc etc.

[@CyberGizmo]

Yeah will add that to the list thanks Harry for the suggesiton

[@nourway3639]

Great content but I really hope you do more explanation in labs (computer) instead of presentations to make more sense

[@whtiequillBj]

Was DOS an Operating System or an advanced memory monitor with a file system?

[@jankowalski2191]

TLB is not "table", it stands or Transfer Lookaside Buffer

[@RobBCactive]

Almost it's Translation Lookaside Buffer, used to cache virtual to physical page translations of VM

[@YanivShoham-d7f]

Thanks DJ, but all MS-DOS history just confusing

[@mpdunner3698]

Why are you even bringing up what MS-DOS did? I went from HP-UX (Bell kernal) to MS-OS/2. We supported MS-DOS execution but under our virtual memory system.

[@RonJohn63]

As much as we all deservedly hate billg, he didn't actually say that about 640KB.

[@runderwo]

20:00 TLB is translation lookaside buffer, not referring to the page table itself. It's another layer of indirection that provides caching semantics.

[@CyberGizmo]

I don't see how you can say that, nearly always present in any processor that utilizes paged or segmented virtual memory

[@AdvaTced]

yea, lets explain entire content of a whole book section in one 30min lecture lol... I can understand this lecture because i'm just refreshing my knowledge, But lets imagine someone new to this... it's not a good explanation.

[@AlexSanchez-qy9jd]

You have a great way of explaining these concepts! I enjoy when you give us some of your experiences with these systems in the past.
