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.
