External Hard Drives
An external hard drive is a device stores important data but is located outside of the computer rather than inside the computer (internal). Typically, most computers do have an internal hard drive but newer threats have risen such as a multitude of different viruses, so external hard drives have become popular because the data stored on them will be safe if the computer were to get a virus. Sometimes an external hard drive is needed just for the added extra memory.
The external hard drive usually will sit on a surface near the computer such as the PC tower or a tabletop, the hard drive is housed by a sturdy enclosure that usually boasts a fan meant for cooling. The external hard drive synchronizes with the computer via a interface cable (the most common being a Firewire or a USB interface) in which user information, data, and programs can be transferred between the two.
An external hard drive can store just about any data, which is useful if you’re worried about Trojan horses, spyware, viruses and other malicious computer bugs that could potentially harm your important data and information. An external hard drive can be used to store a complete back-up of your computer’s content, pictures and images, movies, music files and important documents. When you are not using the external hard drive, then simply turn it off or safely disconnect the interface from the computer.
External hard drives essentially operate like a memory key because they are just as portable. If you need to take your external hard drive to work or to a friend’s house, then simply disconnect the interface from your computer and hook it up to your friend’s computer or your work computer. When the hard drive is hooked to a computer, it will be assigned a letter, so when you need to find it on your computer or save something to it then simply look for the letter and save it to that. You can save all your programs that you use at work onto the hard drive and bring it home, allowing you to create a work environment on your home computer.
An external hard drive can reduce the need to hide files and folders on your computer, such as financial information. All you have to do is save it on the hard drive and then store the hard drive in a safe location when you’re not using it. This also makes it easy if you need to access information quickly, simply plug up your external hard drive and your ready to go. If you are worried about your important information, data and programs being lost of damaged, then investing in an external hard drive would probably be a great idea.
