I heard sequential access is used in old devices such as video CDs and are cheap in cost and direct access is used in many devices today like magnetic disks such as hard drives which are expensive .
you've explained sequential vs random access. the later one you've explained is random access not direct access. in direct access you've blocks of memories where there are multiple of memory locations in each block. you can randomly access any of the block but you can not access the memory locations randomly in direct access. Kindly recheck.
Their major difference is in the mode of data access. This results in their difference in data access time: sequential access is slow while random access is fast.
I wonder the two terms random access and direct access are quite the same, but for random access, usually we mean the time spent to access any part of the memory with the same amount of time, hence the name random
@@henryhachihung difference is in direct access there are blocks and within the blocks there are many locations so time to select the block is random but within the block each location is selected through sequential access. i think your 2nd example is of random access or direct access having each block contains only one loaction. BTW thanks for your great explanation
Faizan Afridi Yes you are right. As far as I know, what’s happening inside a actual RAM module is that the data are randomly stored in the memory slots, not in any particular order, such that when access the data again, the time needed is always the same. But still have to check this out.
You are the man. This is how you show an easy example
what are the advantages of Sequential Access? Why use it when Direct Access is faster?

I'll never gonna forget this easy explanation till my last breath.
😀
Thx 😊😻👍😼
So easy to come the point after the explanation
you've explained sequential vs random access. the later one you've explained is random access not direct access.
in direct access you've blocks of memories where there are multiple of memory locations in each block. you can randomly access any of the block but you can not access the memory locations randomly in direct access.
Kindly recheck.
Thanks ✌️
thank you very helpful
this is so easy explanation, thanks man
thank you very helpful
thx man helped alot
OMG!U ARE INSANE KEEEP UP THE GOOD WORK!
This it such a excellent example!!!😀
Great demonstration
Amazing video
Super it helps mee
Ni Hao, can you explain the difference between direct access and random access?

Great example
The best one!
If a chinese accent explains I undertaan
Great video thanks alot!!
Glad you liked it!
Ni Hao. Can you explain why we call memory Random Access and not Direct Access Memory.
