A:Answer HDD (Hard Disk Drive)
An HDD uses spinning disks (platters) to read and write data. It's a traditional storage technology with moving parts, making it slower, larger, and more prone to mechanical failure. HDDs are more cost-effective for large storage capacities.
SSD (Solid State Drive)
An SSD uses flash memory to store data, with no moving parts. This makes it faster, more durable, and energy-efficient. SSDs provide quicker data access and boot times, making them ideal for operating systems and applications, though they are more expensive per gigabyte.
