Daily Note


  1. As I mentioned last week, I will not be here this week, and Monday of next week.
  2. We are completing our work on computer organization
  3. You should begin preparing for a summative assessment. The summative assessment will include the following standards: 
    1. Define the Boolean operators: AND, OR, NOT, NAND, NOR and XOR.
    2. Construct truth tables using the above operators.
    3. Construct a logic diagram using AND, OR, NOT, NAND, NOR and XOR gates.
    4. Define the terms: bit, byte, binary, denary/decimal, hexadecimal.
    5. Outline the architecture of the central processing unit (CPU) and the functions of the arithmetic logic unit (ALU) and the control unit (CU) and the registers within the CPU.
    6. Describe the main functions of an operating system.
  4. Your work for this class is to review these standards. If you have any questions, please ask on our class discussion board. 


Our Big idea

The big idea for today is Computer organization.

The essential questions for this topic are:

How does a computer actually work? You know, like, really?

It takes time to explore and really understand a big idea. If you want to
learn more about computer organization (which is connected to today's daily note), please click here .

We are learning this because as a designers must understand scientific and technical innovation. Designers use systems, models, methods, and processes to solve problems.

Reminders & routines:

Please read and follow these reminders:

  1. IF today ==  testing_day_for_me:
         remember to go get tested!
