What is duplicate?
well duplication of data means that same information is being used or entered more then once....
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.
What are the disadvantages of data redundancy?
with data redundancy there willbe more wastage of memory space as same type of data willbe saved many times when to want to see the data all duplicate results will come
What is a mirror in Internet?
A mirror in computer terms refers to a constant copy. Which means that two or more disks are holding the exact same data at all times. The files are constantly kept in sync, so that if one of the disks fails, you won't lose any data.
Advantage of Data redundancy?
One advantage of data redundancy is increased data availability and fault tolerance. By storing the same data in multiple locations, the system can continue to function even if one copy of the data is lost or corrupted. Data redundancy also helps improve data retrieval speeds by allowing data to be accessed from multiple sources simultaneously.
Potential duplicate means?
Potential duplicate means that there may be another one the same.
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.

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.
What does it mean to over write on a floppy disk?
If the same data is already in the floppy disk or any other disk, and you are again copying the same data, then it is called the overwriting ..
What is duplicate data?
Data duplication is the process by which multiple rows of the same data gets inserted into a database. For example consider the employee table Employee Name Emp Num Age AAA 111 20 BBB 222 22 If we insert another row with data "AAA 111 20" Then it would cause data duplication.
Is duplicate and replicate has the same meaning?
Yes it does it means make the same
