Basic Storage Concepts
What type of storage keeps data even when the computer is turned off?
Secondary Storage
What type of storage uses magnetism to store data?
Magnetic storage
What type of storage uses laser light to read and write data?
Optical storage
What type of storage has no moving parts and uses flash memory?
Solid-state storage
What storage device would you use to move files between computers?
USB flash drive
What is the name for storage that holds data permanently, unlike main memory?
Secondary Storage
Name one magnetic storage device found inside most computers.
Hard disk drive
What optical disc is used to store computer data that can be read but not changed?
Compact disc read-only memory
What small portable device plugs into a USB port to store and transfer files?
USB flash drive
What type of storage is best for watching movies at home?
Digital versatile disc
What is the main reason secondary storage is needed in a computer system?
Because main memory is temporary and loses data when power is off
What magnetic storage device is a high-capacity removable disk used for backups?
Zip disk
What optical disc is commonly used for movies and video programs?
Digital versatile disc
What type of memory is used inside solid-state storage devices?
Flash memory
What storage device would be best for backing up school files?
USB flash drive or external hard disk drive
What is the difference between main memory and secondary storage?
Main memory is temporary; secondary storage is permanent
How is magnetic tape different from magnetic disk in how data is accessed?
Magnetic tape is sequential; magnetic disk is direct access
Why is a digital versatile disc able to store more data than a compact disc?
It uses more advanced laser technology and higher data density
Give two advantages of solid-state storage over magnetic and optical storage.
Faster, more durable, no moving parts
Which type of storage would be best for a camera or gaming console and why?
Solid-state storage because it is small, durable, and fast
Explain why secondary storage is essential for saving programs, files, and operating systems.
It keeps programs, files, and operating systems safe even when the computer is off
Compare magnetic tape and magnetic disk based on speed, access, and use.
Magnetic tape is slower and sequential; magnetic disk is faster and allows direct access
Explain how optical storage devices store and read data using laser technology.
Lasers read and write data by reflecting light off the disc surface
Explain why solid-state storage is more reliable and durable than other storage types.
No moving parts, non-volatile, more resistant to damage
Choose the best storage device for long-term backup and justify your choice.
External hard disk drive or solid-state storage, because they store large amounts of data safely
