I am deaf. But I can understand your explanation because of the subtitles. Thank you so much sir....🙂your explanation

[motivatewithme]

00:04 Disk scheduling algorithm aims to minimize seek time
00:51 A CD is a circular platter made up of multiple CDs.
01:35 Data is stored in sectors on the platter surface.
02:14 Data storage on hard drives involves tracks, surfaces, and sectors
03:03 Moving the read write head to the desired track
03:48 Seek time is an important aspect of operating systems.
04:41 Seek time is the time taken to move the read-write head to the desired track.

Thank you so much sir. This simple thing was taught to me in my college in a very much complex way. But after seeing your explanation, things are becoming very easy.

It's been 2-3 years since watching your videos and I would say, you have a simplest way to explain such complex topics. Thank you so much sir ❤❤❤

[BilalHassan-vyoi]

I like your style of saying "HELLO DOSTO"

[NigarF]

You have already win my 💖 ...u r So genuine person.. nicely explained 👍 May Almighty shows the rain of mercy upon you..

[vishnumodh]

Masterclasses by the master himself...coming from ur coa series.. That's fab too.Thanks sir🙏🙌🔝

[magicianthakur]

Sir I am following your channel after memory hierarchy . I love the way that u use to comprehend any topic

[nileshsrivastava]

Nice explanation. I think total no of bits should be 40*8 = 320bits for 1TB

🎯 Key Takeaways for quick navigation:

00:00 🖥 *Disk architecture is a crucial topic in Operating Systems and computer organization, often asked in exams.*
01:34 🔄 *Platters, surfaces (upper and lower), and read-write heads with actuator arms are fundamental components of disk architecture.*
03:35 📀 *Tracks, both in upper and lower surfaces of platters, are the next element in the disk architecture sequence.*
04:33 🛤 *The movement of the read-write head is limited to forward and backward on tracks, distinguishing internal and external tracks.*
05:34 📊 *Sequence: Platters ➔ Surfaces ➔ Tracks ➔ Sectors ➔ Data. Questions often involve calculating total tracks, sectors, or disk size.*
06:56 💽 *Example calculation: Total tracks = Platters × Surfaces × Tracks, with values often given in powers of 2 for easier computation.*
07:55 📏 *Disk size calculation involves multiplying platters, surfaces, tracks, sectors, and data capacity, usually given in bytes (often in powers of 2).*
09:26 💾 *Disk size conversion: 2^40 bytes = 1 terabyte. Understanding kilo, mega, giga, tera conversions is essential for accurate answers.*
10:30 🤔 *Number of bits*

Sir u r M watching ur videos in 2x speed for ugc net exm revision.... Tq sir .. Cnt tell u hw much u have helpd me throughout my exm prepartion.... Hope i ll clear my exm✌tq once again🙏🙏🙂

[Hjain]

I just realized I'm watching this for so long now and you sir have helped me a lot but I still hadn't subscribed or liked your videos and I felt so bad. So now I'll go back and like all your videos and I have subscribed now. So sorry !

[kirtitegta-]

Really a good explanation with boys calculation ✌️

[PoojaSingh-kkip]

Thanks for such amazing lectures... 💥Really appreciable, helpful and so sweet of you for extremely easy and simple explanations sir 😊

[mumtahinahmed]

i really CANT thank you enough for this good quality helpful playlist... but here regarding the last part, "the number of bits required" I think the ans should be ....
there was 2^40 bytes... so when we will be asked for number of required bits we need to convert bytes to bits. That is

2^40 x 8
= 2^40x 2^3
= 2^43
threfore number of bits required is 43 bits 😇
i think thats the correct way!!!

Consider a hard disk with 16 recording surfaces (0-15) having 16384 cylinders (0-16383)
and each cylinder contains 64 sectors (0-63). Data storage capacity in each sector is 512
bytes. Data are organized cylinder-wise and the addressing format is . A file of size 42797
KB is stored in the disk and the starting disk location of the file is <1200, 9, 40>.
What is the cylinder number of the last sector of the file, if it is stored in a contiguous
manner? Sir please give explanation of this question

[MdAl-AminAhmed-fthw]

Thanks from a student of NSU, Dhaka. Without your video, I couldn't pass my engineering so smoothly.

[amanthakur]

Nice sir please help to 12 standard students sir our future depend upon u please sir

[arkadeepsen]

I paused at 9:11 by mistake and it reminded me of Amitab Bachchan🤣 Anyways excellent teaching sir! Thanks a lot!!
