Which of the following is not an advantage of magnetic disk storage?
Which of the following is not an advantage of magnetic disk storage?
The correct option is A The access time of magnetic disk is much less than that of magnetic tape
None of the above is not an advantage of magnetic
disk storage
The biggest advantage of magnetic disk storage over
main memory is persistence of data. The RAM chips that house your main memory
contain huge numbers of tiny electric switches, each storing a bit of
information. When the power goes off, all of that information disappears
forever. Your hard drive, on the other hand, has a magnetic platter covered
with tiny zones of charged magnetic fields. Those magnetic fields stay there,
storing your information even when you aren't actively using your computer.
One of the greatest things about magnetic disk
storage is its ability to fit a tremendous amount of information into a small
amount of space. Hard drives stay the same size but are able to fit more and
more information onto magnetic platters. High-end hard-drive storage is
measured in terabytes -- thousands of gigabytes of information. Memory sticks
cannot store nearly as much data.
advantages of magnetic disk storage and main memory
is a bit like comparing apples and oranges. Magnetic disk storage is used in
mechanical hard drives to keep track of permanent information. Main memory, on
the other hand, is used by RAM chips to temporarily store the data the computer
needs to calculate and track the programs it runs. Computers use both, because
each has its own advantages.
