The one is round,while the other is long and thin.
Some examples of dynamic units are magnetic disks, magnetic drums, and magnetic tapes
magnetic tapes are cheaper
There are many measures of memory access. They vary in speed the fastest being magnetic tapes. That may not be a popular choice in this technological age. The next fastest would be magnetic disks, followed by Semiconductor memories and then compact disks.
There are primarily two types of magnetic tapes: analog tapes and digital tapes. Analog tapes store information using varying magnetic fields and were commonly used for audio recording. Digital tapes store data in binary form and are used for data backup and archival purposes.
Cassette tapes.
Yes, they ARE magnetic
Magnetic Disks, otherwise known as 'Floppy disks'. The last generation of these disks were 3 1/2" and used a ridgid plastic case, to contain the magnetic disk within. Not very floppy. The early versions were 7" and 5" and were contained in soft plastic outer sleeves. These were actually floppy.
Before Floppy disks were available, people still transferred data. It used to be with help of punch cards, reel to reel tapes, and cassette tapes. The early home computers used cassette tapes.
True.
