While a hard drive does have volatile memory on it in the form of a cache, the user doesn't have access to it.
Modern Computers have both volatile memory - RAM and non-volatile memory - Hard Disk
No, hard drive is a non-volatile device. Volatile memory devices store data temporarily and lose data on power cut. However hard disk retain its data and hence is non-volatile memory.
Volatile Memory requires power to maintain the stored memory. Eg. Random Access Memory (RAM) Non-Volatile Memory does not require poer to maintain the stored memory. Eg. Hard Disk, Compact Disk, Flash memory.
I believe that you mean to ask if hard disk drives are considered volatile storage media or not. Volatile memory is memory that is lost when the storage medium is not being supplied with electricity. Hard drives do not need power for storage, only for reading and writing data from and to the platters; this means that hard drives are not volatile storage media.
If you want an example, all 'RAM' (Random Access Memory) is volatile - once power is removed the data is lost. Compare this to a CD or your hard disk drive.
The hard-drive (hard-disk) is used to store data in a non-volatile form. Working in RAM (memory) is classed as "volatile" in that the data disappears as soon as the computer is switched off.
Saving. Values can be saved by writing them to non-volatile memory such as a hard-disk file.
A hard disk is a device that is used to store large amounts of data in a computer system. Hard disks differ from other memory because they are non-volatile, they retain the data even when they do not have power.
Yes, a hard disk is a non volatile storage medium. Non-volatile means that data is still there after you turn the computer off and back on.
Volatile memory refers to memory that loses its state upon losing power. Computer RAM is volatile. Compare to nonvolatile memory (Hard disk drives, USB NAND flash storage devices, CD and DVD optical media, floppy media)
Hard disk drive is a storage device.its is a non-volatile storage device
I'm not sure what you mean. If you mean 8 gigabyte Hard disk, yes, that's sufficient. If you mean 8.75 RAM, maybe. RAM and Hard disk are different things. RAM is memory that is volatile - it's deleted when you switch your computer off. The hard disk is non-volatile: It stays there forever, until you delete it.
