Secondary Storage (Optical, Magnetic, Solid-State & Cloud)

[@charlottebruce8198]

wow, this is so much better then my lessons!! thank you so much for making these videos (:

[@jazzediceberg1175]

Optical storage - 1:49 Magnetic storage - 3:26 Solid-state storage - 5:10 Cloud storage - 6:51

[@Projects-zy3jv]

you are actually so good at explaining im so surprised someone can explain something this well. thank you so much

[@elizas1921]

Amazing videos, I’ve already watched a bunch in prep for thurs! You’ve helped me thru the school year, thank you!!

[@rmsgaming9577]

life saver my g. I've got my GCSE computer science tomorrow.

[@arayasimms1607]

how'd it go?

[@eloisecat2458]

mocks in a week i thought i was completely done for but these videos make me think i have a chance thank you

[@user-sf1td2rq4g]

Next Monday guys!!! edit: TOMORROW GUYS!

😬😬😬

[@brightmusic8770]

How did it go?

[@syperhanic7560]

I really hope these papers are gonna be the same difficulty as the mocks we’ve done, I’ve found them quite easy so far so hoping for don’t throw in a curveball

[@toby3594]

Alluvium most people got 4s and 5s in the mocks, I personally found it quite hard, so I hope it will be easier

[@syperhanic7560]

Toby O'Connor how good is your teacher? The main reason why we’re doing so well as a class is because our teacher is literally the best in the school by a mile

[@toby3594]

Alluvium I mean our teachers alright but it could be because we didn’t acctually do a proper mock, it was like some pixl papers

[@syperhanic7560]

Toby O'Connor pixl papers? We use them in maths sometimes. That’s deffo not a proper mock. It might be because computer science is such a new gcse that there are basically no practice papers for schools. Good luck in the prem next season btw

[@jeremycai5870]

My exams tomorrow good luck to you guys

[@hansgopro1]

i’ve always struggled with this topic i just don’t think my teacher explained it well, however your video is great and clear thank you so much i’ll subscribe and like

[@lbell2009]

this is a very helpful video, thankyou!

Good Luck everyone and thank you Computer Science Tutor

Can the magnetic disk be interfered by electromagnets? Love the video, very informative!

[@MrBrownCS]

Yes, would probably void the warranty though 😀

[@bozzy0162]

Cheers! Good luck everyone!!

wow, I found this video really helpful ..thank you

[@babikiromer5699]

Hi, i keep commenting on your videos, thankyou for your replies in the other videos, they are really really helpful, im just nervous because my exam is on monday. Anyways, what do you mean when you say binary data is stored as variations of height on the disk's surface, i dont quite get it.

[@MrBrownCS]

For optical, it means the surface of the disk is being changed so that light is reflected differently. Representing binary is all about finding two things to represent the 0s and 1s, and in this case, it's just dents in a disk

[@babikiromer5699]

Oh, so the direction of the light reflection determines what binary value is assigned?

[@MrBrownCS]

Kind of the other way round - the laser will burn the 'pit' into the disk, say representing a 0, then when it reads that data the light will not be reflected directly up (like if it was flat, representing 1), so it can tell it's representing 0 based on how the light reflects

[@babikiromer5699]

Ohhh, i get it now, so if i explain this in an exam question asking me to explain the way in which optical storage works, am i eligible for full marks?

[@jio3522]

Hi, is it possible to say that magnetic storage can be more prone to mechanical wear due to there being moving parts, great video .

[@MrBrownCS]

Yes precisely, that's a good way of putting it

[@samul6055]

How is flash memory linked to SSDs? and are flash drives and USBs a type of solid state?

[@MrBrownCS]

The terms are slightly ambiguous, but flash memory is the overarching term - solid-state is a flash memory technology. It's hard to answer your second question because they are all based on the same idea, that non-mechanical circuits are used to store the data

[@samul6055]

thanks

You deserve a nobel peace prize

Can you play the Magneto disk on a cd player like of you have music downloaded to the cd ?????

anyone here for last minute revision

Good luck lads

[@bentotech5161]

hy,i like your videos

[@salmaj5551]

thank you

[@Bigblackninja5]

So have I got all 4 of these or? In my pc I mean

[@MrBrownCS]

Probably not (and not cloud of course, although you may use it), but many computers use a mix of solid state and magnetic.

[@isaacraja2082]

Here in 2021, watching this vid to save my cs grade 😂😭

[@phytr1001]

good luck guys, in exactly 1hr and 7 minutes we will be sitting this exam ahhh

how did the exam go? did these videos really help ik this was 3 years ago lol but 😭

[@fallenout4times438]

Hey! Does it matter if we use disc or disk, or is there a big difference?

[@MrBrownCS]

No, doesn't matter 😃

[@HDKidt]

Fallen Out 4 Times j

[@saimasaim3704]

Yes It Does, Term Disc Refers To Optical Storage Device Such As CD However, Disk Is Used For Magnetic Storage Device Such As Floppy Or Hard Disk. Otherwise, You Can Check On Google.
