  1. Tools for Maintaining and Optimizing Windows

  2. MMC • Shell program that hold individual utilities called snap-ins • Start MMC from the start menu, Run option (type MMC) • You can now add tools to the console, such as Device Manager • Many companies sell 3rd party utilities as MMC snap-ins • Activity: • Start mmc and have look at the options in there. • Click on file open and write down the file names that can open up: • ………………………………………………………………

  3. Windows Control Panel • Most commonly used tool: • Modify registry • Change system configuration • System Properties • Device Manager

  4. Computer Management MMC • Control Panel-Administrative Tools (Text, Ch 18, page 483) • Event Viewer • Task Manager (not an MMC) enables you to see applications and program running on PC

  5. CD and DVD Media

  6. Introduction • CD stands for Compact Disk • CD – primary method for long term storage of sound and data • DVD is Digital Versatile Disk • DVD used for movies, backups and high-capacity storage • Different formats: CD-ROM, CD-R, CD-RW, DVD, DVD+RW • Activity (circle the correct choice): • Can a normal CD rewrite information on itself? • Yes No

  7. CD-ROM • CD’s first invented by the audio industry in the 80s • Computer industry realized the same technology can be used to store data • Data stored using microscopic pits • Laser beam reflects off the surface of CD and combination of lands and pits represent binary numbers

  8. CD-ROM Formats • Analogy of hard drive and file formats (NTFS, FAT32) • Original CD-ROMs, used for music, organized in CD-Audio format • CD-Audio lacks error checking, unsuitable for data or applications • CD-ROM ISO-9600 (High Sierra) incorporates error checking • All software applications use CD-ROM format

  9. CD-ROM Speeds • Original CD-ROMs processed data at 150 KBps) • Too slow for many tasks such as software installation or copying data • Manufacturers introduced faster CD-ROM drives • Each increase in speed measured in multiples of 150 KBps

  10. CD-R • A way for users to create their own CD-ROMs • CD Recordable standard introduced in mid 90s • Any CD-ROM drive can read data recorded on a CD-R • Data cannot be erased or changed (single session, multi session) • CD-R drive speeds composed of record and read speeds) • 8x/24x drive will burn 8x150 KBps and read at 24xKBps • Activity: There is an old CD ROM of speed 4X/8X, Calculate its speed in Kbps? • …………………………………………………………………

  11. CD-RW • Looks like CD ROM but with colored bottom side • CD re writable not only burns data, but can burn over existing data • Special format Universal Data Format allows drag and drop to CD-RW drives • CD-RW drives have 3 specifications: write speed, rewrite speed, read speed • Can reuse CD-RW disks • Activity: There is a CD ROM states 8/6/12, What does 8, 6 and 12 refer to? • …………………………………………………………………

  12. Advantages of CD-ROM and DVD Drives • Large storage capacities • Portability • Data cannot be changed • Sturdiness • Special capabilities • Low cost • High speed

  13. CD-ROM vs. Hard Disk Drives • There is no physical contact between the CD-ROM and the reading device. • Storage tracks allow more data storage. • Hard disks are less expensive and getting larger. • Optical devices are used for archiving. • Data is written to a CD-ROM by creating pits and lands on the CD surface.

  14. DVD Media • DVD Video records up to 2 hours of video • Uses MPEG-2 standard of video and audio compression • DVD ROM is read only format, up to 17GB of data • DVD-R similar to CD-R up to 3.95 GB on each side, record only once • DVD Multi can read disks of all 6 dvd formats + all cd media disks

  15. DVD: A Super CD-ROM Alternative • DVD-ROM: read only; holds up to 17 GB of data • DVD video: 4.7 GB; holds up to 135 minutes of video • DVD-R: recordable; holds up to 3.95 GB of data per side • DVD-RAM/RW: slow gaining acceptance because of incompatibilities

  16. Connecting CD-ROM and DVD Drives • Adapter boards: Enhanced Integrated Drive Electronics (EIDE) or Small Computer System Interface (SCSI) • Sound cards with CD controller on board • SCSI host adapter • EIDE connector

  17. Audio Capability and Access Time • CD-ROM ISO Yellow Book standard • International Organization for Standardization (ISO) 9660 standard • Two important values: • Data transfer rate • Mean access time

  18. Installing CD-ROM and DVD Drives

  19. Controller Cards • Select the controller card before buying the CD-ROM. • Use a secondary Integrated Device Electronics (IDE) controller on the motherboard. • Ensure a proper connection.

  20. Multimedia • Multimedia presents graphics, data, sound, and video in an integrated way. • The Microsoft Multimedia PC Marketing Council, now the Multimedia PC Working Group, generates standards for multimedia computers. • The current standard, MPC Level 3 (MPC3), sets several minimum requirements. • Video-capture software provides the interface for importing, exporting, and editing video formats.

  21. Troubleshooting a Device Conflict • Load only device drivers for the SCSI device. • Use the F8 key. • Try the /? option with the device driver executable. • Look in the device documentation. • Find the latest drivers. • If no solution works, choose between the devices or go to a multiple boot configuration.

  22. Installing CD and DVD drives • File structure for optical drive different from MS-DOS file allocation table • Special driver for MS-DOS to recognize this device as a drive

  23. Installing EIDE Drives

  24. Chapter Summary • CD-ROMs provide durable, removable storage for archiving. • Newer CD-ROM technology provides multimedia support. • DVD is an extension of CD-ROM technology. • DVD can be used to store multiple formats. • EIDE and Ultra DMA/IDE drives solve earlier drive problems. • SCSI drives offer performance and reliability benefits.
