    Study Notes

    Data Communication Codes

    • Data communication codes are essential for effective information transmission, ensuring data is converted into standardized formats.
    • Different types of data communication codes include Data Link Control, Graphic Control, and Alpha/Numeric Character codes.

    Types of Data Communication Codes

    • Data Link Control Character: Facilitates orderly data flow between source and destination.
    • Graphic Control: Relates to data syntax or presentation at the receiving terminal.
    • Alpha/Numeric Character: Represents letters, numbers, and punctuation using various symbols.

    Binary Codes

    • Utilizes only two digits, 0 and 1, making them ideal for electronic systems due to simplicity and efficiency.
    • Compact representation allows for effective data storage and processing across computers and digital technologies.

    Alphanumeric Codes

    • Represents letters, numbers, and special characters through combinations of symbols.
    • Common standards include ASCII and Unicode, promoting consistent data interpretation across systems.

    Character Encoding Standards

    • ASCII: Assigns numerical values to characters, allowing text data exchange between computers.
    • EBCDIC (Extended Binary Coded Decimal Interchange Code): An eight-bit encoding mainly for IBM systems.
    • Unicode: Expands beyond ASCII to include numerous characters from different languages, thereby enhancing global communication.

    Visual Data Representation

    • Barcodes: Encode information using a series of bars and spaces, widely used for product tracking and inventory management.
    • QR Codes: Two-dimensional barcodes that hold more information than traditional barcodes, easily scanned with smartphones.

    Specialized Coding Systems

    • MICR (Magnetic Ink Character Recognition): Used in banking for checks; characters printed in magnetic ink facilitate secure processing.
    • OCR (Optical Character Recognition): Converts scanned text images into editable text, optimizing document management and data entry.

    Standard Organizations

    • ISO (International Organization for Standardization): Develops global voluntary standards; founded in 1947, headquartered in Geneva with over 22,000 standards.
    • ITU (International Telecommunication Union): UN agency focused on telecommunications standards and ICT development in developing countries.
    • IEEE (Institute of Electrical and Electronics Engineers): International organization promoting development in electronics and communications.
    • ANSI (American National Standards Institute): U.S. standards agency, coordinating voluntary standardization; represents the U.S. in ISO matters.
    • EIA (Electronics Industry Association): Develops industrial standards for telecommunications and data sectors.
    • TIA (Telecommunications Industry Association): Trade association facilitating market development and standardization in the technology industry.

    Internet Standards and Governance

    • IAB (Internet Architecture Board): Advises on Internet architecture and manages processes for creating Internet standards.
    • IETF (Internet Engineering Task Force): Engages with network designers and operators to evolve the Internet's infrastructure and operations.
    • IRTF (Internet Research Task Force): Focuses on long-term research initiatives related to Internet technology.
