Storage Devices
A storage device is a means of storing data in a computer. It serves as a long-term memory, allowing the computer to access and retrieve data even when the system is powered off. There are two main types of storage devices: primary and secondary.
Primary storage devices are located on the computer's motherboard and are volatile. This means they are lost when the computer is powered off. Primary storage devices include hard disk drives (HDDs), solid-state drives (SSDs), and cache.
Secondary storage devices are located on external devices, such as hard drives, flash drives, and CDs. Secondary storage devices are non-volatile, meaning they retain their data even when the computer is powered off. Secondary storage devices are faster and more expensive than primary storage devices, but they offer a larger capacity and are more durable.
Examples:
Hard disk drive (HDD) is a common type of primary storage device that uses a hard disk to store data.
Solid-state drive (SSD) is a type of primary storage device that uses a flash memory to store data.
Cache is a type of secondary storage device that stores frequently used data from the hard disk.
Flash drive is a portable, solid-state storage device that can be used to store data.
CD is a type of secondary storage device that can be used to store data
