The correct answer is D. Both B and C.<\/p>\n
Non-volatility is the ability to retain data without power. This is an important advantage of magnetic tapes and disks, as it allows them to be used for long-term storage. CCDs, on the other hand, are volatile, meaning that they lose data when power is removed.<\/p>\n
Magnetic tapes are a type of data storage medium that uses magnetic tape to store data. They are typically used for backup and archiving purposes, as they can store large amounts of data and are relatively inexpensive. Magnetic tapes are also non-volatile, meaning that they can retain data without power.<\/p>\n
Magnetic disks are a type of data storage medium that uses magnetic disks to store data. They are typically used for primary storage, as they are fast and have a high storage capacity. Magnetic disks are also non-volatile, meaning that they can retain data without power.<\/p>\n
CCDs, or charge-coupled devices, are a type of semiconductor device that is used to convert light into an electrical signal. They are commonly used in digital cameras and image sensors. CCDs are volatile, meaning that they lose data when power is removed.<\/p>\n
In conclusion, the correct answer is D. Both B and C. Magnetic tapes and disks are non-volatile, which is an important advantage. CCDs, on the other hand, are volatile.<\/p>\n","protected":false},"excerpt":{"rendered":"
