1. Hard Disk Drive (HDD): This is the primary storage device in most computers. It uses spinning platters and a read/write head to store data magnetically. HDDs are typically large in capacity and relatively inexpensive, making them ideal for storing operating systems, applications, and user files.
2. Solid State Drive (SSD): These drives use flash memory chips to store data. They are faster and more durable than HDDs, but typically have a smaller capacity for the same price. SSDs are commonly used as boot drives for operating systems and are increasingly becoming the primary storage device in new computers.
3. RAM (Random Access Memory): While not technically a long-term storage resource, RAM is crucial for a computer's operation. It temporarily stores data and instructions that the CPU needs to access quickly. RAM is volatile, meaning it loses its data when the power is turned off.
These are just three examples, and modern computer systems can use a variety of other storage devices, such as optical drives (CDs and DVDs), USB drives, external hard drives, and cloud storage.
