What is the difference between hard disks and floppy disks?
hard disks are generally contains within the computer and contain FAR more memory than a floppy disk does. floppy disks generally contain 1.44 mb where as hard drives are constantly developing and are currently about 1TB MAX. floppy disks are external in the same way as CD's
How do you remove a write-protection off a floppy disk?
The old 5.25 inch disks had a notch that is covered/uncoverd for write protection. The not so floppy 3.5 inch disks have a little plastic slide that did the same thing. Software disks in that format might have a notch that can be covered with tape.
Is a flash drive the same thing as a external memory card?
yes, external memory counts as portable/External Hard drives, USB flash sticks/drives, SD cards, CD's/DVD's and floppy disks (ancient but still count :P). Anything that you can put files,pictures, movies, etc on counts as external memory.
Why are floppy disks useful?
Presumably because they are an easier way to carry around data than dismantling and transporting a hard drive.It is highly doubtful whether floppy disks are useful today, they have too little capacity. A USB flash drive serves the same purpose (simple to carry data around) in a smaller format and with more storage space.For permanent backups or installing programs, CDs and DVDs have taken over the role of the floppy disks.
Why floppy disks are not often used for data base?
A database to function effectively needs high speed access to stored data.Floppy disks CAN be sued for storing a simple database, but there are some severe limitations:slow access speeds means slow database response, especially if the computer cannot hold the entire database in local memory for sorting, etc.severely limited storage space may limit the database formats available, as many newer database have considerable data storage overheadconstant read/write operations can wear floppy disks causing them to fail fairly quicklydata cannot easily be shared with more than one userOlder databases, such as Paradox, would happily use floppy disks for storage. Problems are likely to occur if the same was attempted with a modern database, such as MySQL.
What are the similarities of a floppy disk and a hard disk?
In their basic form, floppy discs are common hard disks are the same technology. They both use magnetism to store and read data. They both use a spinning platter read by a horizontally moving read head. The key differences are that hard disks have the data and reader in the same package, this is why hard discs have evolved in storage capacity while floppy disks remained the same. It was necessary for the written layer of a floppy disk to have the same data density and dimensions as they had to be compatible with floppy disk drives. However with hard discs the drives and read heads could evolve along side the data layer. Hard discs now have metal platers, and store data at a much higher density. The speed of the mechanisms are much much faster. New technologies such as perpendicular storage can be added and have no impact on compatibility.

How do you properly handle a floppy disk?
3.5" floppy: Keep the floppy disk away from magnets, static areas (TVs and some fabrics), and areas with high humidity and/or extreme temperatures.Leave the metallic shutter closed at all times.Preferably hold it by the edges.Old-style floppies:Same as 3.5" disks, but without the metal pieces and rigid shell.Avoid the same dangers posed to the 3.5".Avoid bending/folding the disk.Keep it in a sleeve/cover as much as possible.With all floppy disks.. don't touch the interior disk!
What is the DOS command used to copy ALL of the files on one floppy disk to memory and then copy that same information to multiple other floppy diskettes with one command?
DISKCOPY is the command to copy all of the files to memory and then copy those files to another disk. Unfortunately, it does not copy to multiple disks. Here is the syntax: DISKCOPY [drive1: [drive2:]] [/1] [/V] [/M] /1 Copies only the first side of the disk. /V Verifies that the information is copied correctly. /M Force multi-pass copy using memory only.
What is full form of SSDD?
If you mean in computer technology it's a term used to describe an older and largely unused format of Floppy disks "Single sided, double density" disks. It could also mean "Same sh*t, different day" depending on whom you ask.
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.
Where were floppy disks made?
The first floppy disks were made in 1971 for IBM to store System/370 microcode images on, for use during µIPL when starting the machine at powerup. System/370 microcode was stored in fast SRAM chips in the machine, which lost their data when powered off. These floppies were 8 inch diameter and stored only 80KB of data. The same companies that made magnetic tape made floppies.
