3.	A DVD is an example of a(n) __________ ?
	hard disk
	optical disk
	output device
	solid-state storage device
	Answer: optical disk Explanation: A DVD (Digital Versatile Disc) is an example of an optical disk. Optical disks are a type of storage medium that use laser technology to read and write data. DVDs are used to store and play high-definition videos, software programs, and other types of digital data. Hard disks are internal storage devices used in personal computers, laptops, and servers to store large amounts of data permanently. Output devices are devices that are used to display or present data, such as a monitor or a printer. Solid-state storage devices, also known as flash memory, are a type of non-volatile storage device used in memory cards, USB drives, and other portable devices.

7.	How is it possible that both programs and data can be stored on the same floppy disk ?
	A floppy disk has two sides, one for data and one for programs.
	Programs and data are both software, and both can be stored on any memory device.
	A floppy disk has to be formatted for one for the other.
	Floppy disk can only store data, not programs.
	Answer: Programs and data are both software, and both can be stored on any memory device. Explanation: Option (b) is the most accurate answer. Programs and data are both types of software, and they can be stored on any type of memory device, including floppy disks. The distinction between programs and data is largely artificial, and the computer treats them both as streams of bits that can be read from and written to storage media. When a floppy disk is formatted, it is prepared to hold any type of data, including programs, and the disk operating system can manage both types of data on the disk.
