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

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.
