Chapter 10 Multimedia And Mass Storage

MP3 is a version of MPEG compression used for audio files. MPEG is a widely used format for compressing audio and video files, and MP3 specifically focuses on compressing audio files. It reduces the file size without significantly affecting the quality of the audio, making it ideal for storing and transmitting audio files over the internet or on portable devices.

DVD's have different storage capacities depending on the type. A standard single-layer DVD can store up to 4.7 GB of data, while a dual-layer DVD can store up to 8.5 GB of data. Therefore, it is possible to store 8.5 GB of data on some DVD's.

The colored strip on an IDE cable is used to indicate the side of the cable where pin one is located. This is important because pin one is the designated starting point for data transmission and must be properly aligned for the cable to function correctly. Therefore, the statement is true.

A TV tuner card and a video capture card are not the same thing. A TV tuner card allows the user to watch and record television programs on their computer, while a video capture card is used to capture and digitize video signals from external sources such as cameras or VCRs. Although both cards involve capturing video, they serve different purposes and have different functionalities.

The correct answer is true because when only one speaker connection is used, it should be connected to the green sound port on the sound card. This is usually the middle port and is designed to receive the audio signal from the speaker. By connecting the speaker to this port, the sound card will be able to properly transmit the audio signal to the speaker, allowing for sound playback.

The explanation for the given answer is that the sampling rate of a sound card refers to the number of samples or measurements taken of the analog sound signal within a specific time period. These samples are then converted into digital data that can be processed and reproduced by the sound card. Therefore, the higher the sampling rate, the more accurately the sound card can capture and reproduce the original analog sound signal. Thus, it is true that the sampling rate of a sound card is indeed the number of samples taken over a period of time.

Fault tolerance is the term used to describe the computer's ability to respond to a fault or catastrophe, such as a hardware failure or power outage. It refers to the system's ability to continue functioning or quickly recover from such events without any significant disruption or loss of data. This is achieved through redundancy and backup mechanisms, which allow the system to switch to alternate resources or recover data from backups in case of a failure.

Sampling rate is a measure of how many samples per second are taken when digitizing an analog signal. It represents the frequency at which the signal is sampled. Hz, or Hertz, is the unit of measurement for frequency, representing the number of cycles per second. Therefore, it is the appropriate unit to measure sampling rate, as it indicates the number of samples taken per second.

A storage device that uses memory chips to store data instead of spinning disks is called a solid state device. This type of storage device is known for its faster data access times, lower power consumption, and greater durability compared to traditional spinning disk storage devices. Solid state devices are commonly used in computers, laptops, and other electronic devices to provide reliable and high-performance storage solutions.

The surface of a CD does not store data as pits and lands representing either a 1 or a 2. Instead, it stores data as a series of microscopic indentations, or pits, which are read by a laser. The presence or absence of these pits represents the binary code of 0s and 1s used to store data on the CD. Therefore, the correct answer is False.

Dynamic disks don't use partitions or logical drives; instead, they use dynamic volumes, which can be resized. Dynamic disks provide more flexibility in terms of managing storage space compared to basic disks. With dynamic disks, you can create volumes that span multiple disks, create fault-tolerant volumes using RAID, and extend or shrink volumes as needed. This allows for easier management of storage space and better utilization of disk resources.

RAID 1 is the correct answer because it duplicates data on one drive to another drive, providing fault tolerance. In RAID 1, data is written simultaneously to two drives, creating an exact copy or mirror of the data. If one drive fails, the other drive can still function and provide access to the data, ensuring data integrity and availability.

The CD is not an example of a solid-state device because it uses optical technology to read and write data. Solid-state devices, on the other hand, do not have any moving parts and use electronic circuits to store and retrieve data. Flash memory, jump drives, and SD cards are all examples of solid-state devices as they store data electronically without any mechanical components.

Windows refers to RAID 0 as a striped volume. In RAID 0, data is divided into blocks and distributed across multiple disks. This allows for improved performance as data can be read and written simultaneously from multiple disks. However, RAID 0 does not provide any fault tolerance or data redundancy, meaning that if one disk fails, all data is lost.

CD drives use the CDFS (Compact Disc File System) or the UDF (Universal Disk Format) file system. The CDFS is commonly used for CDs, while the UDF file system is used for newer CD formats such as DVD and Blu-ray. Both file systems allow for the organization and storage of data on CDs, making CD drives the correct answer for this question.

Tape drives are an inexpensive way of backing up an entire hard drive or portions of it. These drives currently have capacities of 20 to 800 GB. Tape drives are known for their high storage capacity and cost-effectiveness compared to other options like CD, DVD, and flash drives. They are commonly used for long-term data storage and backup purposes in industries where large amounts of data need to be stored securely.

The light blue port on a sound card is typically used as the line in for audio. This means that it is used to connect external audio devices, such as a microphone or an audio source, to the sound card for recording or input purposes. It allows the user to input audio signals into the computer system.

Most sound cards today support the audio compression method also used by HDTV called Dolby AC-3. Dolby AC-3 is a widely used audio coding format that allows for high-quality audio with efficient compression. It is commonly used in home theater systems and multimedia devices to deliver surround sound. Sound cards that support Dolby AC-3 can decode and play back audio encoded in this format, providing users with a superior audio experience.

TIFF (Tagged Image File Format) is the correct answer. TIFF files are larger than JPEG files because they retain more image information, resulting in better quality when printing photographs. Unlike JPEG, TIFF is a lossless compression format, meaning it does not sacrifice image quality to reduce file size. This makes TIFF ideal for professional printing and archival purposes where preserving image details is crucial.

MIDI stands for Musical Instrument Digital Interface. It is a file format that contains a set of standards used to represent music in digital form. MIDI files do not contain actual audio data, but instead contain instructions that tell a device or software how to generate the sound. MIDI files are commonly used in music production, allowing musicians to create and manipulate music using various software and hardware devices. Therefore, MIDI is the correct answer for the given question.
