Question 1

Flash memory storage systems are not subject to mechanical failures like hard drive and optical disc systems, and are therefore more resistant to shock and vibration.

Accepted Answer

Flash memory storage systems do not have moving parts, making them less prone to mechanical failures that can occur in hard drive and optical disc systems. This also makes them more resistant to shock and vibration.

Question 2

"Tracking up data" refers to creating a second copy of important files.

Accepted Answer

"Tracking up data" is not a commonly used term in the context of file management or data backup. It is possible that the intended term was "backing up data," which refers to creating a second copy of important files.

Question 3

Remote storage services accessed via the Internet are often referred to as cloud storage

Accepted Answer

This statement is true.

Question 4

Virtually all computer users today need at least one convenient free USB port, in order to connect external hard drives, flash memory drives, and other storage hardware.

Accepted Answer

Most modern computers come with several USB ports to allow for easy connection of external devices such as hard drives and flash drives.

Question 5

With rewritable optical media, the laser permanently alters the disc surface.

Accepted Answer

With rewritable optical media, the laser heats up the disc surface to create temporary changes that can be erased and rewritten.

Question 6

Storage media are volatile.

Accepted Answer

Storage media are non-volatile, meaning they retain data even when the power supply is cut off.

Question 7

While the memory used for disk caching can be a designated portion of RAM, today's hard drives typically use a disk cache consisting of memory chips located on a circuit board inside the hard drive case.

Accepted Answer

Modern hard drives often have a built-in cache composed of memory chips located on a circuit board within the drive enclosure, rather than using a portion of the system's RAM for caching.

Question 8

Since retrieving data from memory is much faster than from the hard drive, disk caching can speed up performance.

Accepted Answer

Retrieving data from memory is much faster than retrieving it from the hard drive. Disk caching involves storing frequently accessed data in memory, which can speed up performance by reducing the need to constantly access the much slower hard drive.

Question 9

With a CD, the storage medium and the storage device are permanently sealed together to form one piece of hardware called a fixed-media storage system.

Accepted Answer

A CD (Compact Disc) is a removable storage medium, not a fixed-media storage system. It can be separated from the CD drive, which is the device used to read or write data on the CD.

Question 10

USB flash drives are designed to be very portable and very small.

Accepted Answer

USB flash drives are designed to be very small and portable, making them easy to carry around and transfer data between different devices.

Question 11

SSDs are an especially attractive option for portable computers and mobile devices.

Accepted Answer

SSDs are more durable and consume less power, making them ideal for portable computers and mobile devices.

Question 12

Users do not have to be concerned with how files are physically stored on a storage medium.

Accepted Answer

This is the responsibility of the operating system and file system. Users only need to know the location and name of the file to access it.

Question 13

Traditionally, the magnetic particles on a hard disk have been aligned vertically, perpendicular to the hard disk's surface.

Accepted Answer

Traditionally, the magnetic particles on a hard disk were aligned horizontally, parallel to the disk's surface. The shift to vertical (perpendicular) alignment came later to increase storage density.

Question 14

Although cost is a factor when comparing similar devices, it is often not the most compelling reason to choose a particular technology.

Accepted Answer

The statement implies that there are other factors that can be more important than cost when choosing a technology.

Question 15

A common RAID technique is disk mirroring, in which data is written to two duplicate drives simultaneously.

Accepted Answer

Disk mirroring, also known as RAID 1, is a technique in which data is written to two duplicate drives simultaneously.

Question 16

Storage devices can be internal (located inside the system unit), external (plugged into an external port on the system unit), or remote (located on another computer).

Accepted Answer

The statement is true.

Question 17

Many new personal computers come with a C drive partition ready to use for programs and data and another logical drive set up as a recovery partition.

Accepted Answer

This is a common setup for many new personal computers. The C drive is typically used for programs and data, while the recovery partition is used to restore the computer to its original factory settings in case of an issue.

Question 18

Recordable optical discs can be written to, but the discs cannot be erased and reused.

Accepted Answer

Recordable optical discs, such as CD-R and DVD-R, can be written to once, but the burning process is permanent and the discs cannot be erased or reused.

Question 19

One reason advanced users may partition a primary hard drive is to be able to use two different operating systems on the same hard drive.

Accepted Answer

By partitioning the primary hard drive, users can install and run two different operating systems on the same hard drive without them interfering with each other. This is commonly done for dual-booting purposes.

Question 20

The capacity of flash memory cards is continually growing and is up to 256 MB at the present time with even higher capacity cards expected in the near future.

Accepted Answer

This statement is outdated as of 2021. Flash memory cards now have much higher capacities, with some models available in terabytes (TB) range.
