What are the advantages of using a live CD's over hard disk installation?
CD is better than harddisk because CD can be carried anywhere but hard disk can not
Do hard drives store information magnetically?
Yes, there are some surprisingly strong magnets in the Hard Disk Drive. The read/write "head" also is an electromagnet, and the "platter" (spinning disk) is magnetized, but over all not very magnetic.
What are two advantages of SSDs over magnetic hard drive?
faster access to data and reduced power usage
What are the two types of hard disks?
there are 2 type of hard disk 1)internal hard disk 2)external hard disk there are 5 kind of hard disk in each hard disk 1)ATA 2)firewire 3)SCSI 4)RAID 5)fibre channel
Will magnetic fields damage hard drives?
Computer disks (hard drives or older floppy drives) store their information by creating a magnetic charge on a tiny spot of the disk for each little bit of information, which can be read again later. Passing a strong magnetic field over the disk changes the saved charge and it can't be read again as organized information. CDs and DVDs don't store this way, so are safe from magnetic fields.
What is the hard disk?
A hard disk is the physical medium information storage device of most computerized systems. It is an actual disk that rotates at high speed. The surface is coated with magnetic material, and data is stored magnetically on the surface. A tiny read/write head on the end of an arm that can move over the surface of the disk does the reading and writing to transfer the information to and from the medium.
Why hard disk is a magnetic disk?
Common hard disks with read/write heads are magnetic storage. The newer SSD (solid state drive) hard disks are not magnetic because there are no read/write heads. Solid state means no moving parts. SSD drives are labeled as such so you know what you are buying.
How can I pull the files off of my old Hard Drive?
(The following assumes that the hard disk is still in working condition.) If the hard disk is in a computer, you can connect it with another computer over a network, and copy the files over the network. You can also connect the old hard disk to your new computer (using a second hard disk cable); in this case, if you manage to make it work, you can copy the files from one disk to another. In this case, the copying itself should be much faster than copying files over a network.
Definition of hard disk?
A hard disk or hard drive is the place on the computer where files are magnetically written to. The disk uses a metal head to read, write, create, copy, move or delete files on the spinning disk. It is usually located at the front of the computer. Don't turn off your computer while the disk is doing anything. Otherwise, data could be damaged!
Two advantages that main memory has over magnetic disk storage?
Faster access time(uses data bus directly and not through any controller) and no moving partsImprovement in the uniformity of the magnetic filmsurface to increase disk reliability.A significant reduction in overall surface defects to help reduce read/write errors.Ability to support lower fly heights (described subsequently).Better stiffness to reduce disk dynamics.Greater ability to withstand shock and damage
Example of a magnetic storage device?
MAGNETIC Storage Media are the Hard disk drivestypesthat make use ofMAGNETIC PLATTER and Read\Write Sensor (Read - Sensing Polarity, Write - Altering theinclinationi.e. sensor attracted or repelled)over the microscopic area on the Platter) for storing Digital Information in form of Binary Signals.
How the working of floppy disk drive differ from hard disk drive?
The head(s) in floppy drives make physical contact with the floppy disk surface, while the heads in hard disk drives fly over the hard disk surface on a cushion of air created by the platter rotation speed. All other features of the devices are similar.
