Class plan.png What are we going to learn today?[edit]

Hello Class!

Today in class we will focus on:

  • The purpose of the CPU
  • The Von Neumann architecture
  • Common CPU components and their function
  • I can 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
  • I can describe primary memory
  • I can explain the use of cache memory
  • I can explain the machine instruction cycle
  • I can identify the need for persistent storage

We will take notes with this well organized template: Click here for file

Target.png How am I being assessed today?[edit]

I will assess you formatively today, and make a professional judgement to what extent you understand our learning material. I will use observation, your written work, answers to questions, and contribution to class discussions as data to make my decisions. I normally record my observations in a "evidence of learning" spreadsheet, which I will happily share with you privately if you so wish. I usually need a day or two notice.
