MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -An HDD has disc-like objects that are called “platters.” Platters are where the data is stored using an electrical charge. This electrical charge comes from the actuator arm or “read/write head.” Read/write heads are instructed where to move on the platters by the software in the CPU and motherboard.

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: -Disk platters 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.

Detailed explanation-4: -A platter is a large type of dishware used for serving food. It is a tray on which food is displayed and served to people. Its shape can be oval, round, rectangular, or square. It can be made of metal, ceramic, plastic, glass or wood.

Detailed explanation-5: -The platters are made from a non-magnetic material, usually aluminum alloy or glass, and are coated with a thin layer of magnetic material. Older disks used iron(III) oxide as the magnetic material, but current disks use a cobalt-based alloy. A cross section of the magnetic surface in action.
