Wow thank you so much sir! This is exactly what I needed for my class, you couldn't have uploaded at a better time. This is the type of content that I subbed for. Keep up the good work sir!

[stevanvieira]

Best tutorial on internet for ROM, you made my thoughts about ROM much more clear! Thanks 👍

[ayoolanurudeen]

Thank you very much for sharing this knowledge. I have always thought that the Hard disk is referred to as ROM but now i know better.

[gurbanrovshanov]

Well, that's quality teaching right here.. well done!

[repairstudio]

Great great vid buddy but the volume is kinda low but your like me, I have a very low voice ...very chill and relaxed. Love this, you explain very well and I try to explain things to new repair techs and fail miserably, I can only learn and can't teach anything haha. Thank you you've made my job much easier now I can refer techs to you video 😇

Thanks a lot for discussing the ROM in such a detailed and understandable way.

[MahdiLessani-pp]

It was a great explanation and super simple.

Amazing video, i wanted to know how data is stored inside ROM, my mind was blown by how the litteral chip "burning" happens in PROM. I imagine thats how Atari cartridges were made.

Thank you so much ! many information in this video ! can i ask one question plz ? how to read the rom firmware ?

[americansamurai]

Can ROM be replaced? I've been having a problem with it and don't really know. When I ran a diagnosis, the ROM is said to have failed. Thanks for the video and explanation.

[dowkasoussama]

When are you starting Software programs

[laranja]

If I can update my bios or the firmware of a device doesn't that mean I wrote to rom, so I wrote to a read only memory?

[jasvindersingh]

is there any use of rom after the pc started?
because after start the whole operating system works on ram right?

[joshuabordey]

louder please!! my speaker volume is already at 100 and i cant hear well..

[DyingSpaceNeutronStar]

what if you look at..
Windows ROM Memory Error
*"Your PC Ran into a problem and needs to restart. We are collecting ome error info and then we will restart for you.*
*Error Code
*Stop Code
Invastigate and then talk to me or make a video about it

Why would a programmer put this on my brand new toshiba, I know it is a read only not sure which one. something like xml markup? I cant even download chrome he also installed a virtual machine and a vpn, he has added remote access I'm not sure if I'm on the virtual or the physical it will not erase in disk utility on mac everything is overwritten, he is in my icloud sharing it as if we are family... do i have a case to get him for fraud? are there anything I can do, he is all up in my business.. subnet mask network he is dividing my ip address, i think he has put some modules or what ever they are called on motherboard and a wifi card, , my bluetooth turns on on my iphone and im not even touching it i never use bluetooth, he just lives across a field from me im on discovery I dunno im just sick of it

Talk a little bit louder. Your voice is a bit low.
