A track is a concentric ring on a storage disk where data is recorded, while a sector is a portion of a track containing a fixed number of bytes of data. Tracks are circles on a disk surface, while sectors are pie-shaped segments within a track. Together, tracks and sectors make up the layout of data storage on a disk.

A disk sector refers to a sector on a hard drive or other storage device, where data is stored in fixed-sized blocks. A track sector, on the other hand, refers to a sector on a track on a disk, where the data is physically stored on the disk surface. Essentially, a track sector is a subset of a disk sector and is specific to the physical layout on the disk.
The main difference is the method of control: a trackball is controlled by rolling a physical ball with your fingers, while a touchpad is controlled by touching and swiping on a flat surface. Trackballs offer more precision but are less common, while touchpads are more intuitive and widely used in laptops and mobile devices.
The phase difference between two waves is directly proportional to the path difference between them. The phase difference is a measure of how much the wave has shifted along its oscillation cycle, while the path difference is a measure of the spatial separation between two points where the waves are evaluated.
Track friction refers to the force that resists the motion of an object along a track or surface. It is caused by the contact between the object and the track, resulting in a loss of kinetic energy as heat. The coefficient of friction determines how much resistance is present between the two surfaces.
