A computer hard drive is a technical component that is designed to store data. All computers need at least one hard drive to store data like user information and operating system software. Most of the time, hard drives are housed internally, however, with the evolvement of most computer systems, the external hard drive is becoming more and more popular.
Accessing the Internet often exposes PCs to viruses and other security threats like spyware and Trojan horses. As such, it has become more difficult to defend against them. Even using anti virus programs and firewalls does not guarantee your computer’s safety. These online threats, combined with the fact that most family computers are used by several different family members (requiring the use of more memory space) have led to the growing popularity of the external hard drive.
External hard drives have their own casing and sit outside the existing computer tower. This enclosure is somewhat larger than is the hard drive itself. External hard drives connect to your existing computer using a high-speed cable interface. This cable will allow the computer and the external hard drive to communicate effectively. Most of the time, these drives are connected using USB or Firewire cables.
External hard drives are very useful as they allow users to back up data and store vital information in a separate location than in the internal hard drive. This ensures that your stored data does not become compromised by activities that take place both online and off. External hard drives are also useful for storing large DVD images, movies, music and other files of substantial size. In order to ensure safety, leave the external hard drive turned off while you are surfing the Net.
Because external hard drives are portable, and they operate via plug and play, you can tote it with you and use it with any computer that has a USB or Firewall access. This makes transferring large files back and forth from home to work a simple task. All you have to do is plug in the interface!
