Mmd2093 2 4 Presentation Transcript

  • 1. CHAPTER 2 Computer Hardware/Components required for Web use
  • 2. 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
  • 3.
    • 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.
  • 4. 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)
  • 5.
    • 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
  • 6. Connections
    • The various connection methodologies include
      • Small Computer System Interface (SCSI)
      • Integrated Drive Electronics (IDE)
      • Universal Serial Bus (BUS)
      • FireWire
  • 7. 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.
  • 8.  
  • 9. 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.
  • 10. IDE channel
  • 11. 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.
  • 12.  
  • 13. 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.
  • 14.  
  • 15. 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).
  • 16.
    • RAM enables the simultaneously running of many applications.
  • 17. 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
  • 18.  
  • 19.
    • 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
  • 20. Communication Devices
    • Modems
    • ISDN
    • Cable modems
  • 21. Modems
    • Modems modulate and de-modulate analog signals.
    • They provide connectivity through standard phone lines.
    • Modems can be internal or external.
  • 22.
    • Modem speed is measured in baud, and the standard modem speed should be at least 56 Kbps
  • 23. 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.
  • 24.
    • They are more expensive than the conventional analog lines.
    • Example: Streamyx and other broadband service
  • 25. 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.
  • 26. MMD 2093 Fundamental of Web Design Chapter 4 Internet Activities Khairul Noor Azwa Binti Kamarudin
    • Internet
    • Satu rangkaian yang terbentuk dari gabungan rangkaian-rangkaian komputer dari seluruh dunia (inter network)
    Istilah Penting Internet Intranet Extranet
  • 28. 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.
    • perpustakaan maya sejagat (universal virtual library) yang menyimpan pelbagai jenis maklumat
    • , ,
    2. E-MEL
    • membolehkan para pengguna menghantar mesej antara satu sama lain
    • ,
    3. IRC
    • membolehkan sekumpulan pengguna berbincang secara langsung dalam bentuk teks
    • ,
  • 30. samb.. 4. FTP
    • digunakan untuk menghantar atau mengambil fail (maklumat) dari sebuah komputer ke komputer yang lain
    5. TELNET
    • digunakan untuk memasuki dan seterusnya mengguna komputer jauh untuk mencari maklumat atau melakukan sesuatu tugas khas
