Question 1

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

Accepted Answer

With rewritable optical media, the laser heats a special layer on the disc surface which changes the phase of the layer, allowing it to be rewritten. The change is not permanent and can be reversed by reheating the layer with the laser.

Question 2

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

False

Question 3

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 new personal computers, with the C drive partition used for programs and data and a recovery partition for system recovery and troubleshooting.

Question 4

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

This statement is true.

Question 5

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

Accepted Answer

SSDs are lighter, more durable, and have faster read and write speeds compared to traditional hard drives, making them an ideal choice for portable devices.

Question 6

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

Accepted Answer

Disk caching stores frequently accessed data in memory, allowing for faster retrieval and improving overall system performance.

Question 7

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

Accepted Answer

This is true. Users do not need to be concerned with the physical storage of files on a storage medium, as this is managed by the operating system and file system. Users only need to worry about accessing and manipulating the files through the file system interface.

Question 8

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 9

Some view cloud storage as a specific type of online storage that can be accessed on demand by various Web applications.

Accepted Answer

Cloud storage is a type of online storage that can be accessed on demand by various Web applications.

Question 10

"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 creating a second copy of important files. The term "backing up data" is more commonly used for this purpose.

Question 11

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

Accepted Answer

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

Question 12

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

Accepted Answer

In disk mirroring, data is indeed written to two duplicate drives simultaneously as a common RAID technique.

Question 13

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

This statement is true. Most computer users require at least one free USB port to connect external storage devices.

Question 14

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

Accepted Answer

Recordable (or write-once) optical discs can only be written to once and the data cannot be erased or modified afterwards. This distinguishes them from rewritable (or erasable) optical discs which can be written to and erased multiple times.

Question 15

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

Today's hard drives typically use a disk cache consisting of memory chips located on a circuit board inside the hard drive case.

Question 16

Storage media are volatile.

Accepted Answer

Storage media can be volatile or non-volatile. Volatile storage media lose their stored data when there is a disruption in power supply or when they are turned off, while non-volatile storage media retain the data even when the power is turned off. Examples of volatile storage media include RAM, cache memory, registers, and some types of flash memory.

Question 17

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

Partitioning a primary hard drive can allow users to install and use two different operating systems on the same hard drive by creating separate partitions for each OS. This is commonly done by users who need to use different software or applications that are only compatible with certain operating systems, or for those who want to experiment with different operating systems without having to use multiple hard drives.

Question 18

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 any moving parts, making them more durable to physical damage caused by shock and vibration. This also makes them less likely to experience mechanical failures compared to hard drives and optical discs.

Question 19

Flash memory media can be inserted into a reader in several ways.

Accepted Answer

The answer of Flash memory media can be inserted into...

Question 20

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

Accepted Answer

Other factors such as functionality, ease of use, compatibility with existing systems, and overall value proposition may be more important considerations.
