Study Notes

Tablet Computers

  • Touchscreens are the primary interface for portable devices.
  • Two types of touchscreens: resistive and capacitive.
  • Resistive touchscreens respond to pressure; they are less sensitive but offer higher resolution.
  • Capacitive touchscreens detect electrical properties of skin and support multi-touch functionality.

Standards Organizations

  • IEEE: Promotes electronic and computer engineering; publishes technical literature.
  • ITU: Based in Geneva; formerly known as the International Consultative Committee on Telephony and Telegraphy.
  • Standards set by these organizations influence computer architecture and organization.

Parallel Processing

  • Parallel processing enables multitasking and solving complex problems.
  • Some classify parallel processors as extensions of the von Neumann architecture.
  • Multiple independent cores are used for parallel processing, as opposed to a single core in traditional models.

Machine Intelligence: Deep Blue and Watson

  • Watson analyzed terabytes of unstructured data, including medical records and clinical feedback.
  • It completed 25,000 test scenarios and 1500 real-life cases showing its understanding of complex medical data.
  • The work involved consuming extensive medical literature, illustrating the challenge of interpreting human language in computing.

Number Systems Performance Task

  • Differentiation of positional number systems (e.g., Roman vs. binary, octal, hexadecimal).
  • Binary number system has a radix of 2; it represents values in base 2.
  • Various quiz questions on converting numbers between binary, octal, and hexadecimal systems emphasize foundational knowledge in digital computation.

Assessment Rubric for Presentations

  • Scores reflect content accuracy, organization, development of points, and language use.
  • Clear answers, logical progression, and well-supported information are essential for high scores.
  • Grammatical accuracy and a strong command of technical terminology enhance presentation quality.
