MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Platters are further separated in to the tracks and sectors where tracks are concentric circles while sectors are pie shaped wedges on the track. Hard disk stores information in the form of magnetic fields.

Detailed explanation-2: -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-3: -A sector is the smallest physical storage unit on the disk. The data size of a sector is always a power of two, and is almost always 512 bytes. Each track has the same number of sectors, which means that the sectors are packed much closer together on tracks near the center of the disk.

Detailed explanation-4: -The correct answer is Formatting. The process of dividing the disk into tracks and sectors is called formatting. In computer disk storage, a sector is a subdivision of a track on a magnetic disk or optical disc. When a disk undergoes a low-level format, it is divided into tracks and sectors.

Detailed explanation-5: -Tracks and Sectors Tracks are concentric circles that are broken up into storage units called “sectors, ” typically 4, 096 bytes long. The sector is the smallest unit that can be read or written. Tracks are only 75 nanometers wide today, and bit density is greater than one terabit per square inch.
