The term backing storage refers to any non-volatile data storage that will retain a computer's data, even after the computer is powered off. Common types of backing storage devices are hard drives, SSD, external hard disk drives, optical media such as CD or DVD, and flash media such as thumb drives and memory sticks. Older computer systems also used floppy disks and magnetic tapes as backing storage. On modern systems, especially computers like netbooks, cloud storage services may also be used as backing storage.

Why is backing storage needed?

Without some type of backing storage, the computer would not have access to its data after the computer is turned off. For example, volatile memory like RAM loses all information if the computer is turned off or rebooted. To prevent information you have been working on from being lost, it is saved to a backing storage device like a hard drive.

So, the option hard disk and floppy disks are under backing storage type, option C is right.

Pulse code modulation is a method used to convert an analog signal into a digital signal. So that it can be transmitted through a digital communication network, and then converted back into the original analog signal.

The PCM process includes three steps: Sampling, Quantization, and Coding. Pulse code modulation is a method used to convert an analog signal into a digital signal.

Please tell me what is meaning punched card?

Backing store - Computer memory, usually magnetic disks, storing data and programs. Sections of this information can then be copied into the main memory (RAM) for processing. Backing store is cheaper but RAM is faster. Such a hierarchy of memory devices allows a trade-off between performance and cost.

Backing storage is a database for storing our information.

It may be a hard disk, floppy disk, pen drive.

For large systems, we use DB2,My sql,MS access.
