To protect the information that
we want to keep, files, documents, and others, we use the so-called "Hard
Disk," also called Hard Disk, HD, HDD, or Hard Disk, in which the data that we need to save will be
permanently stored. bolts.answerhop
Likewise, the
operating system itself that is used on the PC and all the applications that we
have installed will be saved on the hard disk so that they
are there every time we start our computer.
One of the first discs most
similar to those we know today was created by the IBM company in 1979, and it
was the 62PC model, called "Piccolo," which
only had 64.5 Mb of storage space.
However, the
first hard disk in history was the IBM 3501, also called Rama
I, manufactured by the company in 1956. Although it could only store up to 5 Mb
of data, its size was gigantic since it weighed a ton, and its dimensions were
similar to those of a home refrigerator. tc-bolts.dyifo
At present, not only has the size
of this type of device #$ been significantly reduced, but the technology with
which they work has changed considerably, offering increasingly better solutions
to computer users.
It was especially in the 90s, and
after a series of important discoveries made by different researchers in the
field of computing, that hard drives that had increasing storage
capacity began to be offered. techqueer
In the middle of that decade,
disks underwent the change from being able to store megabytes (Mb) to being
able to store gigabytes (Gb), and today
hard drives are marketed that have a storage capacity of more than 100
terabytes (Tb), that is to say, almost one hundred
million megabytes, which gives us the guideline that there are no limits for the
future construction-bolts.tockhop
How does
a hard drive work?
At
this stage of events, there should not be any user who is unaware that the computer's hard drive is the device
where the operating system is stored and that it allows us to
save the information that we are manipulating to use it again later.
Also
known as Hard Disk or by its initials HD, this device is an extremely delicate
piece of engineering, a mechanical part, and an electronic part, and whose best
characteristic, without a doubt, is that it does not lose the information
stored inside when we disconnect it from the device. Power
supply.
That is why it is
considered a non-volatile memory, thus causing the confusion of many who claim
that their PC "has 500 GB of memory" when in
reality, it is talking about storage capacity.
Today, a hard drive
can reach storage capacities that were unthinkable years ago, when one of the
most expensive and complex drives, such as the Quantum Bigfoot series, had
1.2 GB of space to store documents. Current hard drives reach up to 100
Tb. capacity, which allows us to have an almost unlimited
amount of video, music and documents stored.
As we can
see, the hard disk plays a fundamental role in the PC, even
of equal importance to the memory or the processor that it has, and that is why
in this article, we will learn a little more about this type of device. bacobolts.yictic
