MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -A hard disk drive platter or hard disk is the circular magnetic disk on which digital data is stored in a hard disk drive. The rigid nature of the platters is what gives them their name (as opposed to the flexible materials which are used to make floppy disks).

Detailed explanation-2: -A platter is a circular magnetic plate that is used for storing data in a hard disk. It is often made of aluminum, glass substrate or ceramic. A hard disk drive contains several platters that are mounted on the same spindle.

Detailed explanation-3: -Magnetic disk a medium known as Direct access. A magnetic disk is a storage device that uses a magnetization process to write, rewrite and access data. It is covered with a magnetic coating and stores data in the form of tracks, spots and sectors.

Detailed explanation-4: -The number of platters in a hard drive depend on the physical size of the hard drive, its capacity, how many sectors, and its manufacturer. Therefore there is no set number of platters in a computer hard drive. However, all modern hard drives have two or more platters and if the drive is an SSD, it has none.

Detailed explanation-5: -The disks in a hard drive are called platters and this is where your data is stored. There are typically between 1 and 5 platters stacked on a central spindle, with data being stored on both sides of each disk. Each platter is made of either aluminium, glass or a ceramic material.
