Daily Note

Hello! 

  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. We will be working on: 
    1. Boolean operators
    2. Truth tables
    3. Logic diagram
  4. We will review our formative assessments. Please carefully compare your answers to the answers on the markscheme. You should take about 20 minutes for this. If you have a question, register for an account here - NOT USING YOUR REAL NAME - and post a new question. 
  5. We will learn about a base-16 number system, hexidecimal
    1. Please watch this video
    2. Please print this cheat sheet
    3. Please watch video
       
    4. Please visit this site and look at the lower-right problem set that starts with Hex to decimal
    5. Please don't look at page 2 (the answers are there) yet. 
    6. Ignore the part of the problems that start with 0x
    7. The first problem is 0x5A 0x tells you tis is a hex value. YOU SHOULD ONLY CONVERT 5A
    8. Try all of them USING OUR CHEAT SHEET. 



       
  6. 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.

 

A little less comfortable

Content

You must understand all the standards associated with system fundamentals.  

Process

The key question  here is how does a system integrate into an organization? You should think about the relationship between a system and the organization it provides value to. You should be thinking about every stage of the lifecycle - introducing the system into the organization, changing the system, and legacy systems / data migration. 

Product

Look at any system within an organization and understand how it provides value to the organization. 

A little more comfortable

Content

You must understand all the standards associated with system fundamentals.  You must be able to teach other people about how to correctly design a system, and what factors come into play when designing a system. You should be able to write quiz questions for content and evaluate if an answer is correct, or which is answer is the most correct. 

Process

The key question  here is how does a system integrate into an organization? You should think about the relationship between a system and the organization it provides value to. You should be thinking about every stage of the lifecycle - introducing the system into the organization, changing the system, and legacy systems / data migration. You should plan these systems to support a small business, medium business or an enterprise business. 

Product

Look at any system within an organization and understand how it provides value to the organization. You should also evalaute how these systems might work better in an organization. 

Our Big idea

The big idea for today is System fundamentals.

The essential questions for this topic are:

How do you design a system so it works really well for your client or customer?

It takes time to explore and really understand a big idea. If you want to
learn more about system fundamentals (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.
