The advent of the personal computer revolution over the past thirty years or so has introduced the names for a number of formerly unheard of devices into everyday parlance. The term hard drive, for example, once a term used almost exclusively by technicians and engineers, is something that the average person encounters in both speech and practical activity on a daily basis.
Loosely speaking, a hard drive is basically defined as a digital storage device that uses hard, magnetic plates to store a given amount of data. While the process of digitizing even relatively small amounts of data once required a huge, bulky hard drive mere decades ago, recent and rapid advances in storage technology have made it possible to downsize the physical dimensions of the drive while increasing the amount of storage. Today, not only massive amounts of written data can be stored on a typical hard drive, but vast libraries of audio and visual media can now be kept on a sleek, portable little hard drive that can easily fit in your pocket today.
It should be noted that a hard drive is also the device inside your personal computer which is responsible for storing most of the information and software that keep your machine and its programs running dependably. Incidentally, this is why a hard drive malfunction can be so catastrophic for a computer system. If the hard drive is compromised, the data that your computer needs in order to tell it what to do and how to operate is often rendered basically useless.
In order to avoid these problems and vulnerabilities inherent in keeping important data and other files on a single hard drive, many people have taken to backing up their files on either online web archives, which utilize the vast amounts of hard drive storage space that some Internet based companies offer, or by uploading these important files to a portable hard drive that was briefly described above. Whatever your level of expertise in the computer field, it definitely pays to keep not only the installed hard drive on your personal computer in good working order, but to keep an external, portable hard drive or two around for backup, just in case.
