    • CHAPTER 2 Computer Hardware/Components required for Web use
    • Macintosh vs Windows Platform
      • Macintosh platform
        • Has 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 produce DVD dics
        • Makes multimedia project development easier and smoother
        • Started supporting multimedia project developments far before Windows did
      • 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, its now easier to find multimedia hardware and software for windows compared to the Macintosh.
    • Networking
      • Networking 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
    • Connections
      • The various connection methodologies include
        • Small 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.
    •  
    • FireWire
      • FireWire 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.
    •  
    • 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).
      • RAM enables the simultaneously running of many applications.
    • Sound Card
      • A 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 Devices
      • Modems
      • ISDN
      • Cable modems
    • 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
    • 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.
      • Example: Streamyx and other broadband service
    • Cable Modems
      • They 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.
    • MMD 2093 Fundamental of Web Design Chapter 4 Internet Activities Khairul Noor Azwa Binti Kamarudin
    • PENGENALAN KEPADA INTERNET
      • Internet
      • Satu rangkaian yang terbentuk dari gabungan rangkaian-rangkaian komputer dari seluruh dunia (inter network)
