Does a floppy disk drive use laser beam to read and wright?
No. A laser is not used to read or right to a floppy disk.The laser is usedto read and right data to an optical disk such as a dvd or cd. The floppy disk is a magnetic storage medium. A read right head is basically a small coil. When a current is passed thru the read/right head, itgenerates a magnetic field which aligns the small particles on the floppy disk in one of two directions. the direction of the particle indicates a 1 or 0which is the essence of data on a computer. to find out more details of the construction of a floppy disk and how data is saved, google floppy disk.
How does one do a backup to disk?
Backing up data to disk can be rather time consuming depending on how much data one needs to transfer on to disk. Most computers have a backup facility where one would follow a set on on-screen instructions. Alternatively, one can copy and paste data from folders to the disk.
What are the advantages hard drive?
The disk space is pretty cheap, you can store data without constant electricity, data can be stored in one place, and they have a read/write speed comparable to a CD.
Why is simple disk striping not fault-tolerant?
if one disk fails,data contained on that disk is unavailable
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.
Which one of the following doesn't allow direct access to data 1.Hard disk 2.Zip disk 3. CD 4.Tape?
They all allow direct access to data, however the CD can come in read-only, or write-once format, so that data can only be read from it and not written to it (not written either immediately or after the initial write has taken place).
How can one wipe clean the data on a hard disk drive?
There are many ways to clean the data on a hard drive disk. These ways include erasing and formatting, data wiping aka data dump, and disk wiping stands.
What is the difference between disk duplexing or disk striping with parity?
Disk duplexing is where you're writing data to 2 or more disks, with each disk using its own controller. If one disk fails, the other disk continues to operate with no data loss. Even if you lose the disk controller, it is not a problem since you're using a separate controller for the other disk. It is considered an variation of RAID 1 disk mirroring. Disk striping does not duplicate data as in disk duplexing. It writes (stripes) data across 3 or more disks but uses parity checking for each disk. If one disk fails, the other drives can recreate the data stored on the failed one. It is considered RAID 5 level.
Can files saved on disk be accessed by hard-drive?
Do you mean like a floppy disk, a CD, or a ZIP disk? You should be able to access them unless the files are protected in some way or if the files are corrupted. Does this help? If not, try re-posting your question with a more detailed description of what you want to know. Files downloaded to a hard drive remain on the hard drive of that computer, even if they are subsequently loaded on a CD or floppy disc. If that disc or floppy is opened using a separate computer, the information on the disc is read without involving the hard drive of the computer. No information from the disc is placed on the hard drive of the second computer unless saved to it. yes. you need some sort of interface, called an operating system to arbitrate the exchange of information. ex in dos: copy a:/ c:/ The simple thing to remember a disk,a floppy,a hard disk,DVD,CD,etc are all just storage devices. If something is "copyed" from hard disk to floppy disk then there will be the same data on both.If its "cut" from one and "pasted" to the other then the data will be on the one its pasted to and not on the one "cut" from. In order to access this data an operating system will be needed to read it.If the data was encrypted then the encryption software used will also be needed to decrypt the data again on the computer you are trying to read it.
One kind of computer memory can be accessed for a reading and writing What is this kind of memory called?
If you want the computer to forget what is read and written then Random Access memeory is the best. If you want the computer to remember what is read and written then Saving the writing to the Hard Disk means the writting can then be read at a latter time
How could one recover data from a dead hard disk?
One way of recovering data from a dead hard disk would be to get it repaired at a computer shop and buy an external hard disk enclosure that is compatible with the hard disk. Then you can mount the hard drive and transfer data across to the desired computer.
Can data be stored and received on a floppy disk?
Data can be stored on a floppy disk, since that is what they are designed for. As for whether it can be "received" on one, that is a pretty vague question, as it doesn't address HOW the data is received.
