One of those components is the hard drive.
The hard drive serves as the communication to the rest of the
computer; making it a very important component. The hard drive
also serves as storage for most of the computer’s information.
This includes the operating system and programs on your computer.
As stated above, all components of a
computer need to work together. A fast CPU will be of no use
if the hard drive is slow. This is because the CPU will just
be kept waiting of information coming from the hard drive.
The hard drive also serves as a place
for you to store all your files. If the hard drive goes boink,
all the data you have will be lost.
The hard drive is the most likely computer
component to fail. This is because the hard drive has few components
can be moved. It can be able to store information because it
has round discs that stores it as 1’s and 0’s packed densely
on the disc.
When getting a hard drive you should
first look at the technology. Would you want an Intelligent
Drive Electronics or SCSI? IDE is the common interface for hard
drives. This is easy to use but also limited. SCSI on the other
hand is faster, takes a load of work form the CPU and allows
multitasking better.
IDE is what is usually used by home computer
users. SCSI can be used for home PC’s as well if you really
want the best performance. IDE over the years also has also
gotten near to the speed levels of SCSI. The price of an IDE
is also cheaper.
There is also a newer version called
ATA. However ATA can only be used on motherboards that can be
compatible with it as well. ATA has thinner cables and allow
faster speeds.
If you transfer a lot of data between
computers, you may also want a Fire wire hard drive.
In terms of speed, one should look for
revolutions per minute on a hard drive. Faster rpms of hard
drives means the disc will spin faster and the access to that
area will also be fast. The most recommendable rpms are around
7200.
These are only some of the important
things that a person should learn about hard drives. Hard drives,
together with the other components of the PC all work together
as a unit to function properly.
