What is the difference between a disk sector and a track sector?

∙ 11y ago
A magnetic disk is organized with circles called tracks. These tracks (think of the race track around a field) are the path followed by the magnetic head when reading and writing the signal.
The data is organized into short sections, called sectors. This is just a convenient size of data, rather like a page is a convenient size within a book. When you read or write data, you do not need to follow the whole track as it spins, just as many sectors as contained the data you are interested in.
On the most modern disks, each track holds a megabyte, more or less, and each sector is typically 4096 bytes. The whole disk may have hundreds of thousands of tracks.

The difference between a 0 spot and a 1 spot is the size of the spots magnetization on the disk surface?

What is the difference between physical structure and logical structure of a disk?
well of course one is logical and the other is physical. but one involves the brain while the other has to do with your body or movement
What needs lots of friction?
The braking system on a car depends on lots of friction between the brake pads and the brake disk.
Mass moment of inertia of a disk?
Moment of Inertia of a disk (I) = 1/2MR2 Moment of Inertia of a disk (I) = 1/4MR2
What is the difference between cache and spooling?
Buffering is a method of overlapping the computation of a job with its execution. It temporarily stores input or output data in an attempt to better match the speeds of two devices such as a fast CPU and a slow disk drive. If, for example, the CPU writes information to the buffer, it can continue in its computation while the disk drive stores the information. With spooling, the disk is used as a very large buffer. Usually complete jobs are queued on disk to be completed later. A typical example is the spooler for a printer. When a print job is issued, the spooler takes care of it, sending it to the printer if it is not busy, or storing it on disk otherwise. The main difference between buffering and spooling is that the latter allows the I/O of one job to overlap the computation of another. Buffering only allows the I/O of a job to overlap with its own computation. Nikheel Spooling is better than Buffering all the way... In Spooling,CPU Allows overlap of one Job with the computation and output of other job...whereas in Buffering,the CPU overlaps input,output and processing of a single Job. (Job = Program) Even in a simple system,the spooler may be reading the input of one job while printing the output of a different job. newtest3
What is the relationship between a track and a sector?
track is invisible cirle on hard disk and sector are the segments of these circle
What do you call the subdivision of a track on magnetic disk or optical disk?
A sector
Is a sector a narrow recording band that forms a full circle on the surface of the disk?
false it is a track
What is the difference between a drive and a disk?
The difference between a drive and disk is that a drive is used to read a disk whether it be a floppy disk or a compact disk.
Difference between physical access and logical access between CPU and peripherals?
A logical access assumes that the location to be read or written is contained within a linear address space, while a physical access describes the actual access to the appropriate sector, the location within the assumed linear address space must be converted into the corresponding platter, sector, and track, and the disk hardware must be instructed to access that specific location.
How average time is calculated to read one sector in a magnetic disk system?
Transfer time = revolution time / #sectors per track
What is a sector on a magnetic disk?
Sector is the smallest unit on Hard disk identified & addressed by File System.
What is a parity track?
It's a track (a section of a magnetic disk, or a section of any given storage device that emulates a magnetic disk that uses the the LBA/CHS[Cylinder, Head, Sector]) that the computing device dedicates to store parity data (data to aid in error verification/correction for data that is stored on the disk).
