[tutorial] Computer parts and what they do [Hard Drive]

The hard disk drive is the main and largest data storage device in your computer. Everything on your computer is stored here, The OS (operating system) and all of your files.

The hard drive is sometimes referred to as the "C: drive" mainly because Windows designates the 'c' driver letter to this primary partition on the primary hard drive in a computer by default.

What is an external hard drive?

Think of an external hard drive exactly like your normal hard drive but working outside your computer. Both are extremely similar. Normally, they can be connected to your computer via a USB connection. If you have a 'pen drive'(also known as a USB stick),they work like a miniature external hard drive in the sense that they store date in an external format; an external hard drive is just like a large key-drive.
