Explain the organizational differences between a magnetic disc and an SSD

What exactly is a magnetic disc, and what are some of its common applications?

What does it mean for a solid-state drive (SSD) to have wear leveling, and why is it necessary?

The term "fog" means just what it sounds like in the context of computing. The IoT system consists of what, exactly?

Give a brief definition of magnetic disc.

Suppose that a magnetic dick drive has the following characteristics:   Rotational speed = 20000 RPM HTH switching time = 3 ms Average TTT seek time = 3 ms 6 platters, 1024 tracks per platter side recorded on both sides, 60 sectors per track on all tracks. Sector size = 512. The Questions are as following: What is the drive’s storage capacity? How long it will take to read the drive’s entire contents sequentially?

What is the average time to read or write a 512-byte sector for a typical disk rotating at 15,000 RPM? The advertised average seek time is 4 ms, the transfer rate is 100 MB/sec, and the controller overhead is 0.2 ms. Assume that the disk is idle so that there is no waiting time.

How does an SSD vary from a magnetic disc when it comes to data organisation?What do they share with a disc?

How does an SSD differ from a magnetic disc in terms of organization?What is it that a disc shares with them?
