Transcript of Chapter 9 Multimedia Hardware Mac vs. PC. Overview Macintosh versus Windows platform. Networking...
Overview
• Macintosh versus Windows platform.• Networking Macintosh and Windows
computers.• Connections.• Memory.• Storage devices.• Input and output devices.• Communication devices.
Which Platform Mac or PC?
• Select platform based on– Personal preference– Budget constraints– Project delivery requirements– Type and content of project materials– Availability to target audience
Mac versus Windows
The Macintosh platform:– Was launched by Apple in 1984.– Has a good built-in audio and high-
quality graphics capability.– Includes hardware and software for
digitizing and editing video and producing DVD discs.
– Makes multimedia project development easier and smoother.
Mac versus Windows
The Windows platform:– Is a collection of different vendor-neutral
components that are tied together by the requirements of the Windows operating system.
– Initially focused on business computing and was not suitable for multimedia. However, it is now easier to find multimedia hardware and software for Windows as compared to the Macintosh.
MAC vs. PC• Macintosh• Since 1984 has
been multimedia• Good built-in
audio• Easy to learn GUI
PC• Intended for
business• System beeps and
tiny, tinny speaker• DOS screen-
command driven• Since late 1980’s
provides multimedia capabilities
Macintosh Platform
• All Macs can play sound– Latest include hardware for digitizing
sound
• 8/16/24 bit graphics available
• Can digitize both sound and video
• Requires a mouse
Windows Multimedia PCs
• MPC Standard- manufacturers guarantee that software written to
the MPC standard (labeled MPC compliant) will play on their machines.
• Three levels of minimum requirements: MPC1, MPC2, MPC3
Windows Multimedia PCs
• 1990- Level 1 ( MPC1)– 16 MHz, 386SX, 2MB RAM, 30 MB drive– CD-ROM, VGA video ( 16 colors)– 8 bit audio board, speakers/headphones– MS Windows with Multimedia Extensions
package• Not powerful enough to develop Multimedia• Hardly powerful enough to play it
Windows Multimedia PCs
• 1993- Level 2 ( MPC2)– 25 MHz, 486SX, 4MB RAM, 160 MB drive– 2xCD-ROM, VGA/SVGA video – 16 bit audio board,
speakers/headphones, microphone
Windows Multimedia PCs
• 1995- Level 3 (MPC3)– 75 MHz, Pentium, 8 MB RAM, 540 MB
drive– 4xCD- ROM, MPG support– MPEG1 video playback– Full motion video ( in small window)
with TV quality– CD quality sound
Networking• LANs- local area
networks• Located within short
distances ( such as a campus, or building)
• Allow sharing of resources such as printers
• Ethernet for cross-platform development
• WANs- wide area networks
• Used for long distances
• More expensive to install and maintain
• ISPs like AOL, MSN make it available and affordable
Networking Mac and Windows
• Networking is essential for direct communication and sharing of resources across platforms.
• Local area network (LAN), wide area network (WAN), and Internet connections provide connectivity and networking capabilities.
Networking
• In a LAN, workstations are located within a short distance. They are relatively less expensive.
• In a WAN, communication systems span great distances and are typically set up and managed by large corporations. They are expensive to install and maintain.
• A dial-up connection to the Internet through an Internet Service Provider (ISP) also enables communication.
Networking
• To establish communication between a Macintosh and Windows PC, install Ethernet system and client-server software.
• Ethernet is a method of wiring up computers.
• Client/server software is required for communication and transfer of files.
• Macintosh computers have built-in Ethernet networking, while Windows PCs require an additional Ethernet card.
Networking
• MACs• Have ethernet built
in• Usually run
Appletalk• Need DAVE to
communicate with PC
• PCs• Need ethernet
cards • Usually run TCP/IP
• Need MACLAN to communicate with MAC
Client/server software enables computers to communicate through an ISP
Memory
• Sufficient memory must be allocated for storing and archiving files.
• Memory requirements of a multimedia project depend on the project's content and scope.
• The two types of memory are random access memory (RAM) and read only memory (ROM).
Memory and Storage Devices
• RAM• ROM• Floppy and Hard Disks• Zip, Jaz and Syquest
– Zip – 100MB– Jaz – 1 GB
• Optical Storage CD, CD-R, etc.)• DVD (Digital Versatile Disk) upto 1GB
– DVD-video– DVD-ROM
Input Devices• Keyboards• Mice and Trackballs• Touchscreens• Magnetic Card Encoders and Readers• Graphic Tablets• Scanners• Optical Code Recognition (OCR)Devices• Infrared remotes• Voice Recognition Systems• Digital Cameras• Lightpens
Output Hardware
• Audio Devices• Amplifiers and Speakers• Monitors• Video Devices• Projectors
• CRT – cathode ray tube• LCD – liquid crystal display
• Printers– Injet– laser
Summary
• Macintosh and Windows are the two most common hardware platforms used in multimedia.
• LANs, WANs, Ethernet, and client-server software facilitate communication and connectivity among computers.
• Storage devices include floppy disks, hard disks, Zip drives, Jaz drives, MO drives, DVDs, and CD-ROMs.
Summary• Input devices include keyboards, mice,
trackballs, touchscreens, graphic tablets, scanners, OCR (optical character recognition) devices, infrared remotes, voice recognition software, and digital cameras.
• Output devices include audio devices, speakers, amplifiers, monitors, video devices, projectors, and printers.
• Communication devices include modems, ISDN lines, and cable modems.
