Chapter 10 multimedia and mass storage

Chapter 10-Multimedia and Mass Storage

  • Multimedia devices like sound cards, digital cameras and MP3 players

  • Optical Storage-CD and DVD

  • How hardware devices are used for backups

  • Troubleshooting mass media

Pg 411


Multimedia on a pc

Multimedia on a PC

  • Using sight, sounds and animations to make output real-world

    • But computers store digital information

Pg 411

  • AMD and Intel dominate CPU market

    • Special codes or instructions on their chips

  • Intel

    • MMX

      • Pentium MMX and II

    • SSE (Streaming SIMD Extension)

      • Single Instruction Multiple Data

      • Pentium III

Pg 412


Sound cards onboard sound

Sound Cards & Onboard Sound

  • Used to record and play back sounds

  • Input and Output ports as well

  • Surround Sound

    • Multiple channels that can play sound differently

Pg 412


Sampling and digitizing sound

Sampling and Digitizing Sound

  • Digitizing sound

    • Convert from analog to digital

  • Compressed

  • Synthesized

  • Sampling rate

    • Number of samples per second (hertz)

    • Higher the rate, more accurate the sound

  • Compression reduces the quality

Pg 414


Installing a sound card

Installing a sound card

  • Similar to other installations

    • Addition of audio connectors inside the case, usually for connection for playing audio straight from CDs

  • Physical installation

  • Drivers

Pg 415


Digital cameras and flash memory

Digital Cameras and Flash Memory

  • Digital Cameras like scanners

    • Scans the field of image set by picture

    • Quickly

  • TWAIN is transfer standard

    • USB, Firewire, Serial, etc

  • Can also take out Solid State device

    • Use a card reader

    • Some cameras are now plug and play with video and photo software

Pg 423


Web cams and microphones

Web Cams and Microphones

  • Web cam provides live feed to internet

  • Connect with USB, Firewire, sometimes s-Video or composite

  • Generally need to install software first

    • Chat software can often detect as well

Pg 426


Mp3 players

MP3 players

  • MP3 is a compression system for audio files

  • MP3 player is hardware for playing these files

    • Sometimes refers to other codecs/formats

  • MPEG is a video compression codec

    • MPEG-1, -2, -4

Pg 428


Midi devices

MIDI Devices

  • Musical Instrument Digital Interface

    • Represent music in digital form

  • For playing instruments, not “music”

  • One instrument at a time

  • Many instruments have MIDI ports

    • 5 pin DIN port

    • Input and output ports needed

Pg 436


Cd rom cd r cd rw

CD-ROM, CD-R, CD-RW

  • Different types of CDs can be bough

  • Different types of drives can read and write

  • CD-ROM can read CDs and most CD-Rs

  • CD-R drive can burn CD-R and CD-RW and read CD-R and CD-RW and CD

  • CD-RW can burn CD-R and rewrite CD-RW, but the CD-RW can’t be used in older players

  • CD-R and CD-RW are blue, black or other color

  • CD is silver

Pg 437


Installing a cd drive

Installing a CD Drive

  • Once installed, it appears as a drive letter

  • Usually Parallel ATA-EIDE

    • Set jumpers like the HD

  • If possible, put it on its own cable as master

    • If not, make it slave to HD

  • Don’t forget the audio cable

Pg 439


Using dvds

Using DVDs

  • DVD designed for holding movie

    • 8.5 GB of Data or 17 GB if dual sided

      • Uses UDF format

  • DVD uses shorter wavelength laser than CD, thus more data storage

    • Also has two layers

Pg 444


Any questions

DVDs

Pg 444


Dvd standards

DVD Standards

Pg 445


New standards

New Standards

  • HD-DVD

    • Didn’t make it!

  • Don’t push the tray on the player

  • Use the correct cleaner

Pg 447


Hardware for backups and fault tolerance

Hardware for Backups and Fault Tolerance

  • Data is worth more than hardware

Pg 449

Pg 457


Fault tolerance dynamic volumes and raid

Fault Tolerance, Dynamic Volumes and RAID

  • Fault Tolerance

    • Elimination of a point of failure

    • Ability of PC to respond to a fault and not lose data

  • Redundant Array of Independent Drives (RAID)

    • Many Levels

    • Link drives together to appear as one

    • Hardware and Software Implementations

Pg 458


Dynamic volumes

Dynamic Volumes

  • Example of Software implementation of RAID

  • Types of Disks

    • Basic

      • Classic Drive-Divide up HD into partitions

      • Generally difficult to change partition sizes

    • Dynamic

      • Can allocate space as needed

      • Single drive letter may represent many physical and logical drives

        • Dynamic Volumes-XP and 2000 +

Pg 458


Volume types

Volume Types

  • Simple Volume

    • Like a traditional static partition

    • One area of HD represents on Drive letter

  • Spanned Volume

    • Single drive letter is made up of one or more spaces (partitions) on one or more HD

    • Fill the first partition and then the others

  • Striped Volume

    • Single drive letter is made up of one or more spaces on one or more HD

    • Write data to both spaces evenly. Fill both as it goes

    • Increases performance

Pg 458


Volume types1

Volume Types

  • RAID 5 Volume

    • Striped across 3 or more devices

    • Uses parity checking

      • Extra information so it can rebuild data if part is lost

Pg 458


Hardware raid

Hardware RAID

  • Uses specialized HW

    • Either built into MB or bought as an expansion card

  • The drives that make are part of RAID are an Array

  • Best performance is from having drives of same size, speed, features

  • For servers, it is often useful to have hot swapping

    • Can switch out a drive without shutting down

  • RAID often part of Storage Area Networks (SAN)

    • Specialized network setup for storage
