IB Computer Science Year 1 Higher Level - September 11 2017 Lesson Notes

What are we going to learn today? Hello Class! Today in class we will focus on: 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 If we have time (which we will), I will also talk to you about operating systems and you will learn some cool tools on your computers. We will take notes with this well organized template: Click here for file This is helpful: (you have to enable flash) http://www.hartismere.com/CPU-Fetch-Decode-Execute-Animation-20398	What is our home learning? You should review the material we reviewed today ALU – CU – Registers & Buses – https://www.youtube.com/watch?v=UdHK35N-Kuo&list=PLCiOXwirraUB7V2i0SJ4SSJFqRV_LtgzW&t=6s&index=1 Fetch-Decode-Execute – https://www.youtube.com/watch?v=OTDTdTYld2g&index=2&list=PLCiOXwirraUB7V2i0SJ4SSJFqRV_LtgzW Please review these pages on our wiki, again Architecture of the central processing unit (CPU) Functions of the arithmetic logic unit (ALU) Control unit (CU) Registers within the CPU Primary memory Cache memory The machine instruction cycle
How am I being assessed today? 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.
As a computer scientist, you have: Confidence in dealing with complexity Persistence in working with difficult problems Tolerance for ambiguity The ability to deal with open-ended problems The ability to communicate and work with others to achieve a common goal or solution
