What holds more a CD a DVD a USB flash drive or a media player?
i don't know thats why i am asking you?
when you start the system, and as soon as the booting starts, keep pressing del key from the keyboard, then you will get the blue colored system setup, where you will find some caption for booting, there you can select floppy as the first boot device and then press F10 and y and come out of the system now at the next reboot the system will boot from the floppy.
What portable diskette holds 1.4MB of data?
Although they're not used any more - that would be a floppy-disc
Most common CD-Rs nowadays store 700 MB information and 800 MB CD-Rs are also widely available.
Maximum capacity of a CD-R nowadays is 860 MB.
Maximum capacity of a CD is not strictly defined, depending of production technology and the quality of the disk the maximum capacity could be pushed up to about 875 MB.
A hard disk can be re-formatted--which means it is wiped clean before the person reloads programs.
How long the zip disk can hold?
The original Zip Disks (1994) were 100 Mb, but this was expanded to 250 Mb (1998) and then to 750 Mb (2002).
Finally, Iomega saw the handwriting on the wall (flash drives, camera memory) and put out a Zip-650, which was a standard external CD burner, and began marketing USB drives.
They also marketed the Ditto Tape Drives, Clik 40 Mb drives, and the Jaz external 2 GB drive.
What is the capacity of the floppy disks?
The most common ones most people are familiar with were 1.44MB, but there were many sizes of "floppy disk" from about a hundred kilobytes to a couple hundred megabytes.
Nowadays, the answer is 1.44 for a double sided high density 3.5" floppy disk. This answer is quite different for other types of floppy disks. There are single sided, double sided, single density, double density, high density , 5.25", 3.5", and 8" floppy disks just to name a few of the many, MANY variations.
* low density capacity: 360 kbytes * hi density capacity : 720 kbytes * double hi density: 1.44 megabytes
There are other (rare) formats that can hold more.
How do you save information onto a diskette?
To save info; 1. right-click on file to be saved.
2. After menu opens click "Send to 3 1/2" Floppy (A:)
To Delete info; 1. Right-click "My Computer" to open menu.
2. Left-click "Explore"
3. Left-click 3 1/2" Floppy in left window.
4. On right window choose file to erase
5. Right-click on it to open menu.
6. In "Menu" left-click "Delete"
Not really. They are very failure prone, due to their complex moving parts and the conditions they are usually subjected to.
What type of power connector does a floppy disk use?
It varies. There's no universally adopted external floppy disk drive standard, so it depends on the type of drive and/or computer you have.
Modern (2008) external floppy drives commonly use USB (Universal Serial Bus). This isn't really a "floppy drive connector"; it's just an ordinary USB connector. The drive unit itself contains the electronics to make the floppy drive work with USB computers.
The original IBM-PC line (circa 1981) included an external floppy drive option, which used a 37-pin D-shell sub-miniature connector. These weren't all that common to begin with, and are extremely rare these days.
The early Macintosh computers (circa 1984) included an external floppy drive port, which used a 19-pin D-shell sub-miniature connector.
SCSI floppy disk drives exist, but were always fairly rare.
Some manufacturers introduced external floppy drives with manufacturers-specific (non-standard) connectors. Generally, you had to use the manufacturer's expansion card and floppy drive together.
Some manufacturer external floppy connectors were mechanically compatible with the 25-pin D-shell sub-miniature parallel port connector. This allowed the same computer port to be used for either printer or floppy. However, parallel and floppy are not electrically compatible, so only a computer specifically designed for this would work. Dell used it in some of their laptops (Latitude C series, for example).
Can data be stored on both sides of a floppy disk?
Modern 3.5" floppy disks were/are double sided. Earlier 5.25" floppy disks started out single sided but you could cut out a read only slot and flip them over and use both sides, no guarantees though. Even earlier 8" floppy disks were also single sided but could likewise be cut and flipped over. This is from my own experience not from research.
Floppy disks are still used in a variety of machines (not desktop computers) that were built for years after the floppy was introduced. These machines (such as embroidery machines, machine tool devices, pianos, and some medical equipment) were built to last decades and are still in use.
Floppy disks are also used for art projects and promotional purposes. For a great example, check out www.nickgentry.com.
How many bytes of data can be stored in 1.44 MB floppy?
If kB = 1000 bytes, and a "1.44 MB" disk actually holds 1.44 × 1024 × 1000 = 1,474,560 bytes, then 983 files can fit.
a floppy disk slot is what you put the floppy disk in on a CPU
How do you wipe out data on a floppy disk?
You can use the delete command appropriate to the filesystem of the diskette. You can fully format the diskette using the format utility provided. If you're concerned about sensitivity of the data, you should destroy the diskette using fire or some similar means. It's extremely difficult to "delete" data from a diskette in a way that is definitely unrecoverable.
Which has the least amount of storage space a floppy disk or zip disk?
Floppy disks have only 1.44 MB of storage space. ZIP disks have upwards of 100MB of storage space and are much more resistant to magnetic damage at the same time. However, due to cost-effectiveness, neither are especially well-regarded for consumer use anymore. CDs and DVDs are inexpensive and for the same price will hold on average an order of magnitude more data.
The only advantage of a floppy disk, is its ability to boot. As far as storage, floppy disks are obsolete. Not even a Word document with enough attachments can fit on one. Most computers can boot directly off the CD ROM. Newer PC's can boot off a USB Key. But when all else fails, the floppy is always there to save the day when you've crashed your system, and need to boot to reformat/reinstall windows.
How are data files saved on floppy disks?
Put a floppy disk in the drive. With Windows, go to file save as, then go to the drop down box. At the top of that box, go the 3 1/2 floppy and save it.
it is done by a reading light that passes over dints in the disk which is allocated inside the platic cover which forms the binery cod 1 and 0 forming data blocks form the code, e.g
110110010111011101101

The answer above is refering in principle to how CD's work - NOT floppies. Floppy disks store binary data as a series of magnetic dots on the surface of the disk and are written to / read from by a voice coil (electro-magnet).
How do you access information stored on your hard drive?
HOW TO GET DATA OFF YOUR HARD DRIVE When your computer will not boot up or run at all, and you have no back up of your data, there are ways to retrieve your data. COMPUTER WON'T BOOT There are programs that can boot your computer from the floppy drive or the CD drive. If your computer hardware is all good, but windows won't boot the computer, you can probably boot the computer up from the floppy or CD drive.
I have used a programm called "Spotmau Recovery Disk". It is a program that I downloaded from the internet. The computer I was working on would not boot up at all because of a registry error. I didn't want to us the manufacturers recovery disks, because they erase all the data on the hard drive.
The Spotmau program allowed me to run the computer from the CD drive and use a Data Recovery program to copy files from the hard drive to a flash drive. The flash drive plugs into the USB port. A flash drive can be bought at office supply stores and department stores.
Then I transfered the files from the flash drive to the hard drive of another computer.
I couldn't get the registry problem fixed, so I had to run the recovery disks to get the hard drive back to the point where it was when the computer was bought. Then I had to re-install all the software, and copy the files back.
This is all very time consuming, so be prepared for spending a lot of time working on the computer. COMPUTER WILL NOT DO ANYTHING If the computer will not do anything, you will have to remove the hard drive and put it into another computer. It won't even try to boot or you determine there is a hardware problem. DATA WAS DELETED OR OVERWRITTEN There are also programs that will recover deleted files.
Is floppy disc optical storage?
No. Floppy disks are magnetic media that rely on magnetic polarization to write data to the disk much like a hard drive. Unlike CD media they can be erased by a strong magnet field that effectively scrambles the data tracks.
Why do we need to format a disc for use in a computer?
A container called a filesystem needs to be created on the disk before files can be stored on the disk. The files are actually stored in the filesystem. The filesystem is basically a map of which data is stored where, what the filenames and directory names are, which files are in which directories, who owns the files, what permissions the files have, and when the files were last accessed and/or modified.
How many data can a floppy disc hold?
It depends on a few factors.
The size of floppy disk and the size of the CD-ROM.
Floppy disks aren't use very much today, however the latest and most common generation of floppy disks was the 3.5 inch variety with a capacity of 1.44 megabytes of storage. There was a rare 2.88 capacity disk, however for this answer I will refer to the common 1.44MB disk.
CD-ROM's are typically 680 megabytes. There are some CDs that hold 700MB, but again the typical disk is 680MB. Mathematically, this yields 472 floppies per CD. Differences in file sizes and/or block space may shift this slightly.
It's safe to say that a CD can hold 450-470 floppies.
