CHAPTER 2Computer
Hardware/Components required for Web use
Macintosh vs Windows PlatformMacintosh platform
Has launched by Apple in 1984Has a good built-in audio and high-quality
graphics capabilityIncludes hardware and software for digitizing
and editing video and produce DVD dicsMakes multimedia project development easier
and smootherStarted supporting multimedia project
developments far before Windows did
Windows platformIs 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, its now easier to find multimedia hardware and software for windows compared to the Macintosh.
NetworkingNetworking is essential for direct
communication and sharing of resources across platforms.
Personal area network (PAN) Local area network (LAN) Metropolitan area network (MAN)
Wide area network (WAN) And Internet connections provide
connectivity and networking capabilities. A dial-up connection to the Internet through
an Internet Service Provider (ISP) also enables communication
ConnectionsThe various connection methodologies
includeSmall Computer System Interface (SCSI)Integrated Drive Electronics (IDE)Universal Serial Bus (BUS)FireWire
Small Computer System Interface (SCSI)SCSI can connect internal and external
peripheral equipment and devices that conform to the SCSI standard.
SCSI cards can be installed on Macintosh and PC platforms.
SCSI is preferred for real-time video editing, network servers, and situations that require mirroring.
Integrated Drive Electronics (IDE)IDE connections are also known as
Advanced Technology Attachment (ATA).
They connect only internal peripherals. They can connect four peripherals
mounted inside the PC. The circuitry for IDE is less expensive
than SCSI.
IDE channel
Universal Serial Bus (USB)It is a standard for connecting devices to the
computer using the plug and-play system.
USB uses a single cable to connect 127 USB peripherals to a single PC.
FireWireFireWire was introduced by Apple in the
1980s. It is the industry standard and provides
support for high-bandwidth serial data transfer, particularly for digital video and mass storage.
It is the most common method for connecting and interconnecting professional digital video equipment.
MemorySufficient 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).
RAM enables the simultaneously running of many applications.
Sound CardA hardware interface that is either built into
a computer's motherboard or inserted into one of the computer's internal expansion slots. Sound cards allow the computer to play digital audio and/or musical instrument sounds. Many sound cards also provide a MIDI Interface
Manufacturer – Creative Lab, Realtek
Microphone - A microphone (colloquially called a mic or mike; both pronounced) is an acoustic-to-electric transducer or sensor that converts sound into an electrical signal.
Speaker – computer speakers external to a computer, that disable the lower fidelity built-in speaker. They often have a low-power internal amplifier
Communication DevicesModems ISDN Cable modems
ModemsModems 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
ISDNISDN 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.
Example: Streamyx and other broadband service
Cable ModemsThey provide Internet access at speeds 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.

PENGENALAN KEPADA INTERNET
Internet
Satu rangkaian yang terbentuk dari gabungan rangkaian-rangkaian komputer dari seluruh
dunia (inter network)
Istilah Penting
Internet Intranet Extranet
INTERNET : Gabungan rangkaian komputer yang
besar meliputi seluruh dunia
INTRANET : Gabungan beberapa rangkaian kawasan
setempat dalam 1 organisasi sahaja
EXTRANET : Gabungan beberapa intranet yang libatkan
beberapa lokasi berbeza
Dari Aspek penggunaan, internet ialah sebuah rangkaian yang memberikan perkhidmatan komunikasi elektronik, capaian jauh, pemindahan fail, penyebaran maklumat, pencarian maklumat dan beberapa perkhidmatan lain.
