4. 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.

5. 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.

guarantee that software written to
the MPC standard (labeled MPC
compliant) will play on their
machines.
Three levels of minimum
requirements: MPC1, MPC2, MPC3

13. Networking
LANs- local area networks
WANs- wide area
Located within short networks
distances ( such as a
Used for long
campus, or building)
distances
Allow sharing of resources
More expensive to
such as printers
install and maintain
Ethernet for cross-
ISPs like AOL, MSN
platform development
make it available and
affordable

14. 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.
1/9/2013
15. 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.
1/9/2013
16. 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.

Client/server software enables computers to
communicate through an ISP

18. Connections
SCSI ( “scuzzy”) – Small Computer
System Interface – lets you add
peripherals ( up to 8)
ID 0 – internal hard disk
Id 7 – computer
Ultra SCSI – 32 devices
In built in MAC – Mac can read PC formatted
devices
Can be installed in PC – PC can not read Mac
formatted devices
SCSI I data transfer rate – 5 MB per sec
SCSI 2 – Fast SCSI – 10 MB per sec , Wide
SCSI – 16 bit width – Fast/Wide SCSI – 20 MB
per se
1/9/2013 SCSI 3 – 32 devices – 40 MB per sec
19. Connections
IDE-Integrated Drive Electronics- connect
internal devices
PC support 2 IDE – Each IDE supports two devices
Circuit less expensive
Only 9GB drive capacity , Only one drive to be
active , Requires main processor time , Failure in
one results in disabling both.
Plain IDE data transfer rate– 2.5 MB per se
EIDE (Enhanced) – 16.6 MB per se
Ultra IDE – 33 MB per se
USB- universal serial bus- “plug and play”
Firewire (IEEE 1394)- supports high bandwidth
serial data transfer among multiple computers
1/9/2013
20. Connections
Media Control Interface (MCI)
Unified command driven method for software
to communicate with the peripheral devices
In windows any hardware device can be
connected with MCI
Drivers from the manufacturer
Device type – animation, videodisc, vcr,
scanner etc
Scripting languages – VB, Icon Author etc
Simple commands – open , close, pause,
record, resume etc
System.ini file (multimedia devices and
drivers)

21. 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).

25. Communication Devices
Modems ( Hayes Compatible) v.90
ISDN – Integrated Services Digital
Network
DSL-Digital Subscriber Line
Cable Modems
1/9/2013
26. Modems
Modems modulate and de-modulate
analog signals.
They provide connectivity through
standard phone lines.
Modems can be internal or external.
Modem speed is measured in baud,
and the standard modem speed
should be at least 56 Kbps.
1/9/2013
27. ISDN
ISDN stands for Integrated Services Digital
Network.
It is used for higher transmission speeds by
telephone.
They transfer data at the rate of 128 Kbps.
ISDN lines are used for networking, Internet
access, and audio-video conferencing.
They are more expensive than the
conventional analog lines.
1/9/2013
28. Cable Modems
They provide Internet access at speeds
100 to 1,000 times faster than a
telephone modem, over the same
cable network that supplies the
television signal.
However, due to noise in the system,
sending rates may be much slower
than receiving rates.
