    9. 9. Computer Literacy<br />Computer literacy refers to a functional understanding of the fundamentals of computers and their uses.<br />Computer fluency captures the essence of business expectations.<br />Knowledge workers should have more than a functional understanding of computers and be swift to pick up new computer skills. <br />Links:<br />Being Fluent with Information Technology<br />Information Literacy<br />Computer literacy standards<br />Internet and Computing Core Certification (IC³)<br />CT3 > Concepts > Digital Technology > Digital Literacy > Computer Literacy<br />
    10. 10. Bits and Bytes<br />A bit—short for binary digit—is a digit that can be 1 or 0. A bit is the smallest unit of information that a digital electronics device can manipulate. <br />A group of eight bits is called a byte.<br />KB = Kilobyte<br />Kb = Kilobit <br />Understanding bits and how they represent information is key to understanding the workings of computers and other digital electronic devices.<br />Bits on a CD<br />Links:<br />Internet connection speed test<br />CT3 > Concepts > Digital Technology > Digital Literacy > Bits and Bytes<br />
    11. 11. Digitization<br />Digitization, also called digitizing, is the process of transforming information, such as text, images, and sounds, into digital representation (1s and 0s) so that it can be stored and processed by computers.<br />Analog information such as sights and sounds continuously vary over time. If what we see and hear is broken down into their fundamental elements at very short time intervals, it is possible to describe them as values, store them digitally, and reproduce them in a manner that fools our senses into believing they are exact copies of the original. <br />Links:<br />American MemoryThe Universal LibraryDigital personalized radio from PandoraDigital scents from TriSenx<br />CT3 > Concepts > Digital Technology > Digital Literacy > Digitization<br />
    12. 12. ASCII<br />The American Standard Code for Information Interchange, ASCII, pronounced “asskee,” is the standard used to represent keyboard characters in digital form—with 1s and 0s.<br />CT3 > Concepts > Digital Technology > Digital Literacy > ASCII<br />
    13. 13. Binary Number System<br />The binary number system, also called the base 2 number system, is a number system with only two digits: 0 and 1.<br />The hexadecimal number system, or base 16, is used in digital graphics as a shorthand for color representation. Also known as Hex, this number system includes 16 digits: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F. <br />Links:<br />Binary/decimal converter<br />Binary Digits<br />Introduction to Binary Numbers<br />YouTube Video - Mastering Binary Numbers<br />YouTube Video - Binary Numbers in 60 Seconds<br />CT3 > Concepts > Digital Technology > Digital Literacy > Binary Number System<br />
    14. 14. Digital Convergence<br />Digital convergence takes advantage of the fact that digitization standardizes all types of data to 1s and 0s to create devices that combine the functionality of several digital electronics devices into one.<br />As processors become smaller and faster, and telecommunications networks become increasingly pervasive, we can combine the functionality of several devices and technologies. <br />Links:<br />HTC Shift<br />Comcast Triple Play<br />Bundles from Verizon<br />VoIP from Vonage<br />Mobile TV from Verizon, <br />TV on the Web from Hulu<br />CT3 > Concepts > Digital Technology > Digital Literacy > Digital Convergence<br />

    21. 21. Synchronization is the process of maintaining common files and data across multiple devices so that all copies are up to date. <br />Links:<br />Google Docs<br />Microsoft Office Live Workspace<br />Microsoft ActiveSync<br />CT3 > Concepts > Digital Technology > Computing Platforms > Synchronization<br />Synchronization<br />Being able to access all of our data and files anywhere, anytime, from any computer is a challenge. Computer and media companies are all working to develop solutions that will entice users to buy their brands.<br />
