No, it's a device used to create and enhance signals. It's almost never used for data storage.
Why is hard disk drives considered permanet storage?
The data stored on them is persistent (usually), that is they don't lose the data when powered off (unlike RAM).
How does a magnetic disk work?
Digital information is stored in microscopic needles as part of the disk's magnetic coating.
What is a sector on a magnetic disk?
Sector is the smallest unit on Hard disk identified & addressed by File System.
THER ARE TWO TYPES OF STORAGE DEVICES: RAM(RANDOM ACCESS MEMORY DEVICE) CD WRITERAND ROM(READ ONLY MEMORY)e.g DVD ROM.
Uhh no that's completely wrong there are many examples of storage devices. There is magnetic storage devices, optical storage devices, silicon storage devices, and others i cant think of.

Why do you need both Disk Storage and RAM?
Disk storage is used for storing data and RAM (Random Access Memory) is used for running applications and computer services
What is the difference between bit signal and dirty bit?
- bit signal - original intended bit value that was sent
- dirty bit - corrupted incorrect bit value modified by noise events
The dirty bit may or may not match the bit signal originally sent, it may have been modified more than once by different noise events.
Why you cannot use optical disks for all applications?
slow seek time, read only/limited rewrite cycles
Why is recommended not to remove the usb device directly?
If the computer is writing to the USB drive at the moment when you disconnect the device, then you could have, for example, a file on the drive with a beginning and no end. Also, if the computer is dependent on things that are stored on the USB drive, then it needs to know before these files disappear. Before you remove a USB drive, the operating system needs to check with all of the running applications to make sure that it is OK. -DJ Craig
What can I use if a Notebook does not have a DVD drive?
But don't fret - If you need to install software, using another computer, copy the ENTIRE contents of the CD onto a thumb drive (USB memory stick), one preferably 2GB or larger. Then insert the thumb drive on your net book, and install the software from there. (there are of course limitations to this due to the size of the thumb drive)
Now... if you actually want to play a DVD movie.. well.... that's why they invented DVD players... :-)
You have floppy disks can you rewrite or recopy on them?
Given that you have a floppy disc drive then yes you can.
Why would your floppy drive replace the contents of your disk with the contents of another disk?
you need to "write protect" your floppy disk.if you turn the floppy disk over you will see a little tab on the lower right hand corner,push this tab down until you can see the hole through it.your disk is now write protected and cannot be overwritten.
Can you burn movies in DVD format to a 700Mb CD-r?
No. An AVI file might fit. MIGHT fit. However, a 4.7GB DVD-R or DVD+R would be better.
What is Disk-on-Module header?
DOM - Disk on Module is a Flash (Fast electronic memory) Disk with 40/44 pins IDE/Standard ATA Interface used in computer Hard Disks Drive (HDD). Hence DOM can replace regular HDD or other storage device in embedded/computerized systems, which require highly reliable fast storage disk but do not require many Giga Bytes of storage. No need to worry about hard drive crashes due to mechanical breakdowns. DOM has no moving parts! They don

In a sequestered disk, a fragment of the NP has broken loose from the disk and is free in the spinal canal.
SACD is an abbreviation of Super Audio CD by Sony and Philips. DVD density 5+1 channel audio recording. Used mostly for audiophile Jazz and Classics recordings. Has two layers - one for SACD capable player to play one bit DSD recorded audio and other plain CD for any CD player to play PCM.
In sound quality close to DVD audio with multichannel Dolby Digital or DTS recordings. SACD provides more natural non-digital LP like record sound with impressive dynamic range.
See the related link for details.
What is the difference between bits and bytes?
Bits are smaller than bytes. 8 bits equal 1 byte. 4 bits equal a nibble.
Block coding is when error-corrected codes are encoded in blocks. These usually have a very wide range of practical applications.
