Different Kinds of Memory as Fast As Possible

DRAM, SRAM, cache, NAND, flash... So many words, and all of them mean memory, but there are some big differences between them!

As a computer technician and sales rep I have to explain the differences between RAM and HDD everyday.

This is a good video. I use analogies when explaining memory/storage. RAM is your computer's short term working memory, like the memory you would use if you were doing a math problem or doing something like driving (remembering where the other cars on the road are, the hazards, etc before making a decision). Hard drive storage is like your computer's long term memory, like how to ride a bike or what you need to pick up from the grocery store (e.g. data) or someone's face looks like (e.g. pictures) or what a song you listened to before sounds like. Short term stuff is easily forgotten because it only applies to the moment, but is important for multi-tasking or working on complex problems (RAM) and long term memory (hard drive capacity) is important because it allows you to remember more things. If you lack good short-term memory then the only way to deal with situations that arise quickly is to use your slower long-term memory.

in the netherland we have it some easyer
dram is named werkgeheugen (english: work memory)
while hdd/ssd is just geheugen (memory)

My digital circuit design professor linked a Linus video in his lecture videos. Awesome. We have an exam on memories, registers, finite state machines, datapaths, etc. later today. This certainly helped refresh my *memory*.

This is how I used to explain RAM vs. HDD/SSD. RAM is like your short term memory. It lets you do more things at once without losing track of them or slowing down. Your HDD/SSD is your long-term memory to store things like that you want to keep for longer periods of time.

Aww, I was hoping this was a video about differences in DRAM or whatever.  Like what the speeds and timings mean.  This was helpful too though.  Thanks for the video.

it still grinds my gears when someone asks me how much "memory" my computer has (4 gigs of RAM) and they will laugh at me because their computer has over 400 gb...(HDD capacity)

I thought this video was going to be about NAND SLC MLC and TLC (mem-types in an SSD) but still an informative video.

i watched this video while using hotspot shield :D because youtube is banned in my country :(

[mingjiesong]

even though there is an ads at the end, it is still a really useful video ! Thank you

[TXS_SLG]

Speaking of not being plugged into anything - Hotspot Shield ... Linus just relates the AD at the end to anything.

[Num]

I already know everything covered in these vids and I still love watching them, great job :D

[sumitoli]

Great video, Linus! It had certain common facts i didn't knew.
I would like to see 'Maxwell Architecture Exlained - As Fast As Possible'

[MWmDGC]

This channel is a goldmine for Information Technology majors!

[theMarauders]

Im just doing my Computer Architecture class, and well you explained SRAM & DRAM quite well actually..

[Privateuser]

Do a Video on what does 128 bit and 256 bit make a difference on my Graphics Card? I have a GTX 650 Ti 128bit, should i have rather buy a different card using a 384 bit interface and why?

[newtracetriad]

TAPE STORAGE FTW! Its has extremely high capacity and lasts orders of magnitude more than than flash or disk storage

[skely]

You guys should do a video on SDRAM: Synchronous Dynamic Random Access Memory

[Melthornal]

If you want to maintain the health of your hard drive, run Spinrite.  It will:  a, prevent your drive from sustaining damage; b, repair damage it has already sustained; c, recover data from a dying/dead drive.  Run it.

Actually, VPNs CAN improve latency for gaming if it improves the route, and for League of Legends, I go from 80-90 ping not on a VPN to 60 ping on a VPN.
