A hard disk is a storage device that we use to store our data. Which permanently stores the data. It is a circular chip in which digital data is saved. We measure its speed in RPM, obviously the higher the RPM, the higher the speed of REED and WRITE.
Hard disk type
There are two types of hard disks based on data transfer and storage.
(1) Pata Drive

There are two types, depending on how the hard disk connects to the computer system.
