Communication TechnologyUAMG 3053
  • Week 2
  • Development of the New Media

Computer - Hardware
  • Hardware - electronic and mechanical elements
  • Memory Internal storage system and workplace.

    information storage and retrieval.

    600 resolution)
  • CRT Monitor Cathode-ray tube where rays of
    electrons are beamed onto a phosphorescent screen
    to produce image.
  • LCD Monitor - Liquid Crystal Display a display
    technology that relies on polarising filters and
    liquid crystal cells rather than phosphors
    illuminated by electron beams to produce an
    on-screen image.

Conceptual Model of a Computer System
Operating System
  • Basic Communication Model

Computer Development Timeline
  • 1945 - John von Neumann wrote "First Draft of a
    Report on the EDVAC" in which he outlined the
    architecture of a stored-program computer.
  • ENIAC, a machine built by John Mauchly and J.
    Presper Eckert.
  • 1981 - IBM introduced its PC, igniting a fast
    growth of the personal computer market. The first
    PC ran on a 4.77 MHz Intel 8088 microprocessor
    and used Microsofts MS-DOS operating system.
  • 1981 - Adam Osborne completed the first portable
    computer, the Osborne I, which weighed 24 pounds
    and cost 1,795.

Computer .
  • 1983 - Apple introduced its Lisa. The first
    personal computer with a graphical user
    interface, its development was central in the
    move to such systems for personal computers.
  • 1984 - Apple Computer launched the Macintosh, the
    first successful mouse-driven computer with a
    graphic user interface, with a single 1.5
    million commercial during the 1984 Super Bowl.
    Based on the Motorola 68000 microprocessor, the
    Macintosh included many of the Lisas features at
    a much more affordable price 2,500.

Computer .
  • 1984 - In his novel "Neuromancer," William Gibson
    coined the term "cyberspace." He also spawned a
    genre of fiction known as "cyberpunk" in his
    book, which described a dark, complex future
    filled with intelligent machines, computer
    viruses, and paranoia
  • 2002 Apple introduced a new version of iMac
    multimedia computer and iBook multimedia

Software Development Timeline
  • 1948 - Claude Shannons "The Mathematical Theory
    of Communication" showed engineers how to code
    data so they could check for accuracy after
    transmission between computers. Shannon
    identified the bit as the fundamental unit of
    data and, coincidentally, the basic unit of
  • 1953 - John Backus completed speedcoding for
    IBMs 701 computer. Although speedcoding demanded
    more memory and compute time, it trimmed weeks
    off of the programming schedule.
  • 1956 - At MIT, researchers began experimentation
    on direct keyboard input on computers, a
    precursor to todays normal mode of operation.

Software Development Timeline Cont.
  • 1990 - Microsoft shipped Windows 3.0 on May 22.
    Compatible with DOS programs, the first
    successful version of Windows finally offered
    good enough performance to satisfy PC users.
  • 1990 - Microsoft released Windows amid a 10
    million publicity blitz. In addition to making
    sure consumers knew about the product, Microsoft
    lined up a number of other applications ahead of
    time that ran under Windows 3.0, including
    versions of Microsoft Word and Microsoft Excel.
    As a result, PCs moved toward the user-friendly
    concepts of the Macintosh, making IBM and
    IBM-compatible computers more popular.

The Internet
  • A worldwide network of computer that grew out of
    ARPANET, a defense-related communication system
    developed in the 1960s (Severin).
  • An almost worldwide network of computers enabling
    the transfer of data and creating a technological
    system which in turn supports a number of other
    technologies (sub-system) such as email, bulletin
    boards, internet relay chat and the web
  • A worldwide system of interconnected network,
    using the telecommunication infrastructure that
    now supports a large number of types
    computer-based communication exchanges (McQuail).

The Characteristic of the Internet and World Wide
  • 1. An evolving network
  • - new information pools become available as
    additional computers are linked to it.
  • 2. Virtually eliminated geographical and
    time-based constraints.
  • - information are available anytime, anywhere.
  • 3. Decentralization entity.
  • - a collection of independent computer system
    that no individual or organization own.

The World Wide Web
  • Developed initially as a means of scientific
    information exchange in the 1990s.
  • A vast system of computer sites that can be
    visited by anyone with a browser program and a
    computer hooked up to the Internet (Severin).
  • A system of computer servers connected through
    the Internet, and which supports the exchange of
    files (or web-pages) formatted mostly in a simple
    programming language known as HTML (HyperText
    Markup Language).
  • The Web is a technology within a technology- it
    is just one part of the Internet.

  • Web address are known as URL Uniform Resource
  • Convergences in cyberspace Fewer things done on
    the Internet are not hosted in the Web email,
    bulletin boards.

  • The web has provided users with a familiar and
    intuitive interface. PC owners are already
    familiar with GUIs and graphical browsers extend
    this metaphor to the Internet.
  • The webs real-time interaction can save time.

Connectivity, Interactivity, and Digital
  • Connectivity the ability to connect computers,
    telephones, and other devices to other computers,
    devices, and sources of information.
  • Connectivity has made possible many kinds of
  • 1. Email electronic mail
  • 2. Telecommuting (work at home or home office)
  • 3. Online shopping/ e-commerce
  • 4. Databases A collection of electronically
    stored data.
  • 5. Online service, networks, and the Internet.

Connectivity, Interactivity.
  • Interactivity the user is able to make an
    immediate response to what is going on and modify
    the process.
  • It allows users to be active rather than passive
  • Example of interactive devices
  • 1. Multimedia computers text, graphic,
    animation, video, music, and voice.
  • 2. Internet appliances - WebTV, user can
    explore the web, send and receive email, and
    watch regular TV on the same time.

Connectivity, Interactivity
  • Digital Convergence the technological merger of
    several industries (computers, communications,
    consumer electronics, entertainment, and mass
    media) through various devices that exchange
    information in the digital format used by
  • E.g. WebTV, WinTV
  • Technological convergence means that information
    can be communicated and shared among traditional
    (newspaper, television,)and new media
    (satellite, cable, Internet, cellular phone).
