Week 6: Advanced Hardware


In any type of software and system, retaining and not losing the memory and data is very important. If the hard drive for a computer with this system on it crashes, not only is it inconvenient, but it is also an annoyance to get the software back on the computer, the images of the clothing back on the software, and everything else back in order. If the hard drive somehow crashes, it is possible the data back somehow. If the software and the contents of the software are wiped out of the hard drive, there are tools and services in order to recover the data.
            The hard drive stores the software with all its data of the options and articles of clothing in platters coated with magnetic material. The surface of the platter is organized into concentric rings called tracks, which are divided into sectors. A read/write head floats above the platter surface and uses an electromagnet to manipulate and detect magnetic fields. All of the contents of the system and the system itself are stored this way.
            If for some reason a user finds it necessary to delete all of this from their hard drive to protect their own clothing from others, the files containing all of this are not completely gone when it is deleted. The space it now freed is simply made available for later use for a different file to take up. If a user is really paranoid for some reason that all of the files need to be completely gone, overwriting it can delete it permanently.
