What does HDD stand for?

Hard Disk Drive

HDD is a widely used abbreviation for the primary device that computers use to save data. It’s often referred to as a “hard disk” or a “hard drive”.

Unlike some devices that use electricity, an HDD operates using a series of magnetic disks. These disks store information by recording bits as ones and zeroes, a process known as magnetic recording.

An SSD, or solid-state drive, is another form of storage device that serves as an alternative to an HDD. The main difference between the two is how they store and retrieve data.
