Floppy Disk Drives
Floppy disks are an outdated form of magnetic data storage. Questions about floppy disk drives and floppy disks themselves belong here.
768 Questions
They are twisted just to avoid as mush electrical and magnetic interference between them, which is created when the current flows through them.
Answer
Conductors within cables are twisted in order to allow the cable to be flexible.
Can CD-r drive be used as a floppy drive?
Data can be copied to CDs (Compact Discs) which are writable/rewritable and need a CD/DVD burner to write data. The difference between a floppy and CD is that floppy is a magnetics media and CD an optical media (read/write happens with help of a laser light).

When and why would you use floppy disk?
To store small documents or DOS (Disk operating system) programs
Are optical disk disks are random access storage devices?
floppy disks are read/write storage devices, they are a backing store, a non-volatile long term storage which will not lose data when power is lost.
Random access storage is the original term for RAM, the random access memory term was used a a marketing term and has stuck since.
Another Answer
YES - floppy disk are Random Access storage devices.
In what kind of machine is a floppy disk used?
The floppy disk, both the original 8 inch size and the later 5 1/4 inch size were used in all sorts of relatively early computer equipment.
- To distribute and load firmware in a model of the IBM System/360 mainframe.
- For software distribution as well as backup/restore media for the IBM System/38 and various other model midrange computer equipment.
- For software distribution and data storage on a Digital Equipment Corporation (DEC) PDP-11 system.
- For data storage and various word processing machines.
- As system devices and data storage for the original IBM Personal Computer and other similar personal computers.
Its use was replaced by the 3 1/2 inch diskette when it became available.
What are the concentric circles on the disk surface of a hard drive called?
Tracks.
The pie-shaped sections are called sectors.
Groups of sectors make up a cluster.
Type of storage devices are used in hospitals?
I think for anyone to answer this question without sarcasm, you'll need to be more specific as to the details of your question (What's being stored? For what purpose/use? How much (MB/GB/TB)? Why is this question Hospital Specific (radiation, sterility, sanitation/vector control, EMI/RFI interference, etc)?
Use an external USB floppy drive.
If you MUST have internal.... if you're good and creative you -might- be able to disassemble an external USB floppy drive and mount it like an internal drive.
Alternatively, you could hunt down an old LS-120 "superdisk" drive. Its an IDE drive (40 pin connector, like your hdd or cdrom) that reads floppies (in addition to high-capacity proprietary disks)
Why the cable of floppy is twisted on one end?
a floppy ribbon cable
that tricks the computer into using the drive as A:. This is done with the use of a
special twist in the cable that electrically changes the DS configuration of the drive
after the twist. This twist, then, causes the controller to think the drive configured as
B: is really configured as A:. For this reason, during installation of a floppy drive,
always make sure your Drive A: is located AFTER the twist on the floppy ribbon cable. If
you are trying to use a non-standard floppy cable without a twist, you'll have to change
the DS jumper to DS1, or the Drive A: setting.
Why was the floppy disk invented?
Because they are actually floppy disks of magnetic film. They don't seem floppy when you handle them because they're housed in a rigid plastic case that lets you slide them into your computer.
That is if you still have a floppy drive on your computer.
You need 10 duplicates of one floppy this describe how to do this using two different method?
1. You can use WE to copy files on the floppy disk to a folder on the hard drive, then copy contents of the folder to the 10 disks. 2. Use a command prompt window, use the copy command to copy files on the floppy disk to a folder on the hard drive, then use the copy command to copy the contents of the folder to the 10 disks.
What is the data storage capacity of a flash memory?
The largest available SD cards are 32 GB. Stay tuned for more.
How does a computer find data stored on disk?
It uses tracks and sectors to find certain pin points on where the data is. Some of the spots are reserved for certain files.
What are the error codes of floppy drive?
It means a bad spot was detected on the floppy when your computer tried to write or read data from the disk. Most of the time, the drive head that reads the data has become dirty, but sometimes there is physical damage. Rotate the disk in the sleeve. If you see scratches, dents, or folds on the surface, the disk is no good.
There is a floppy disk cleaning kit that can be used to clean the head. They have a white fibre disk in the floppy, instead of the plastic disk with brown magnetic coating.
To use a cleaning kit. Put a squirt of the head cleaning solution in the slot on the cleaning disk, insert it, and access the disk a couple of times (i.e. use the DIR command at the dos prompt). If you have no head cleaning solution, use rubbing alcohol. Don't saturate the disk, just make a wet spot. The disk will wipe the head wet/dry as it rotates.
It is possible to mark bad sectors and do data recovery on a floppy if necessary, but it requires an old copy of the Norton Utilities and some know how to do it.
Good luck.
How does system clock speed affect a computer speed?
There are several numbers and terms here that must be understood before that question can be answered. Many computer processors use a front side bus to communicate with the north bridge and RAM. The speed of that bus determines how quickly the CPU can read and write to memory as well as other peripherals. For ease of synchronizing those systems, many CPUs will set their Core processor speed to a multiple of that FSB. The actual "speed" of your CPU will be determined by the FSB * multiplier, but most CPUs will actually execute several instructions per core clock "tick." It's very difficult to determine how fast a computer will be compared to another one based solely on the clock speeds.
How do you dispose of floppy discs?
There is no special care, just put them in a plastic bag and dispose them like other common parts.
Which disk drive standards uses an 80-conductor cable?
The drive interface that uses an 80-conductor ribbon cable is IDE. IDE stands for Integrated Drive Electronics, an interface commonly used to connect hard disks and optical drives to computers.
Why does Designating the Hard Disk as the only bootable device increase system security?
Because alternative media won't boot with alternative operating systems.
How do you take care of your Disc an Diskette?
Keep it away from Magnets.
Save it from extreme temperatures.
Always store vertically in box.
Do not touch surface while inserting or removing it.
Never leave the disk in the PC after finishing the job.
Avoid over use of the disk otherwise it will not last for more than 6 months
Do not mix disks to be used everyday with those used for long.
Never put any heavy object on disk.
Never carry in loose bags or in pockets.
Never use clips/staples to hold disk.
The floppy cable has a twist in the cable.
Why floppy disk are not a part of a computer system nowadays?
Because floppy disks could only hold tiny amounts of data, only above 1Mb, where as now days memory sticks can hold over 16Gb, over 16,000 times more data. They are also bigger in size too. Most documents and files wouldn't even fit on a floppy, such as MP3 files (songs) which are about 4Mb.
