What do you call the subdivision of a track on magnetic disk or optical disk?
A sector
What is diff between ram and hard-disk?
ram stores instructions and a hard - disk stores data
A 3.5 disk stores how much data?
1.44 Mb
Is a hard disk a magnetic device that stores data?
Yes
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).
What is an optical disks?
an optical disk which stores data optically
A track on a disk is what?
data are stored on a circular tracks the 0s and 1s are represented magnetically
A hard drive stores data on?
hard disk save data on platters. On platters there are tracks and sectors in which the data is saved.
What type of disk normally stores the greatest amount of data?
Blue-ray disc
What stores all files and data on disk?
A hard disk drive records data by magnetizing a thin film of ferromagnetic material on a disk. Sequential changes in the direction of magnetization represent binary data bits. The data is read from the disk by detecting the transitions in magnetization. User data is encoded using an encoding scheme, such as run-length limitedencoding, which determines how the data is represented by the magnetic transitions.
What does a hardrive store data on?
The harddrive stores data on a single magnetic disk, somewhat compareable to a CD in the way that it spins, its round, and it stores data. The "head" of the harddrive uses magnetic fields to excite different areas of the disk to store a binary code such as "00100010." Millions upon billions of these codes are stored on the disk with each code being a single command.
Concentric circles on the disk surface?
Concentric circles, are circles within circles. Each concentric circle on the surface of a disk represents a track, the narrower the circle is, the more data can be stored on the disk.
