FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -A computer hard disk drive (HDD) is a non-volatile data storage device. Non-volatile refers to storage devices that maintain stored data when turned off. All computers need a storage device, and HDDs are just one example of a type of storage device.

Detailed explanation-2: -Hard disks are nonvolatile storage devices that are used to store and retrieve data quickly. Nonvolatile storage is physical media that retains data without electrical power. This means that no data is lost when the computer is powered off, making hard disks suitable for permanent storage of information.

Detailed explanation-3: -A hard drive or hard disk drive (HDD) is a type of data storage device that is used in laptops and desktop computers. An HDD is a “non-volatile” storage drive, which means it can retain the stored data even when no power is supplied to the device.

Detailed explanation-4: -Volatile storage is a type of computer memory that needs power to preserve stored data. If the computer is switched off, anything stored in the volatile memory is removed or deleted. All random access memory (RAM) other than the CMOS RAM used in the BIOS is volatile.

Detailed explanation-5: -The hard drive is the secondary storage standard in modern computing. Many computers bundle hard drives as internal storage mediums, and today hard drives can include spinning disks and solid-state drives (SSDs).
