Memory and Storage Types Quiz

Memory that retains data even when power is turned off. Used for permanent storage of data like the operating system, applications, and user data.

Type of memory that loses data when power is turned off. It's ideal for temporary storage during active processing.

This type of memory is used to store data permanently, like the operating system or user files. It's non-volatile, meaning it retains data even when the computer is off.

This is the computer's temporary storage area that the CPU uses for active processing. Data is lost when the power is turned off.

A special, faster type of memory located close to the CPU that stores frequently accessed data. This helps speed up processing.

The main type of primary memory that the CPU uses to process tasks. It holds data and applications while they're being used, but this data is lost when the power is turned off.

A type of non-volatile memory used in USB drives, SSDs, and memory cards. It allows for permanent storage of data.

A type of storage that uses spinning disks to store data. It's slower than SSDs but offers large storage capacity.

A modern storage device with no moving parts. It's much faster than HDDs, commonly used in laptops and high-performance systems.

External storage devices like CDs, DVDs, and USB drives. They are used for data portability and backup.

The ability of storage to retain data even without power. This is important to store data permanently.

Secondary storage devices offer large storage capacity at a lower cost per byte compared to primary memory.

Accessing data from secondary storage is slower than primary memory because it uses I/O channels.

The speed of primary memory makes it ideal for immediate processing needs, while the slow speed of secondary memory makes it unsuitable.

The type of memory that is fast, volatile, and used for temporary storage. It is accessed directly by the CPU.

The type of memory that is slow, non-volatile, and used for permanent storage. It is accessed indirectly through I/O channels.

A type of SRAM that retains data even when the power is off, making it ideal for storing data that needs to be persistent.

A type of memory circuit that uses flip-flop circuits with transistors to store data.

A type of memory circuit that uses capacitors and transistors to store data.

The process of periodically refreshing the data stored in a DRAM circuit.

A type of non-volatile memory that stores data permanently and cannot be easily changed or erased.

Software that is embedded in a device's hardware and controls its basic functions.

Instructions needed to start and run a computer or device.

SRAM is faster than DRAM.

SRAM has lower density than DRAM.

SRAM is more expensive per bit than DRAM.

Optical storage uses a laser to read and write data onto a disc, such as CDs, DVDs, or Blu-ray discs. It's great for multimedia, software, and archival purposes due to its portability and durability.

Optical discs, while portable and durable, have limitations like lower storage capacity and slower access speeds compared to modern flash drives or hard drives.

Optical devices use a laser to read data encoded as tiny pits (for 1s) and lands (for 0s) on the disc's surface. The laser detects differences in light reflection to read the data.

Optical storage, while still used, is less common than other storage types due to its slow access speeds and limited storage capacity. Modern alternatives like SSDs and flash drives offer faster speeds and larger storage.

Optical storage is known for its relatively low cost for mass distribution, making it ideal for software, music, and movies.

The time it takes for the read/write head to move to the correct track on a hard disk drive.

The time it takes for the disk to rotate to the correct sector under the read/write head.

The speed at which data is read or written to the disk.

The number of tracks per inch on a disk surface.

Flaws on the disk surface that can disrupt data storage.

SSDs offer fast data access, boot times, and overall system performance.

SSDs are resistant to physical shock and vibration due to the lack of moving parts.

SSDs consume less power compared to traditional hard disk drives.

SSDs are considered reliable and less prone to failure compared to HDDs.
