Presentation transcript:

What should we teach regarding… “Understand how instructions are stored and executed within a computer system; “? +++++++++++++++++++++++++++++++++++++++++++ Does the activity support the ‘tick list’? How can we improve it? Can we walk away from today with the ‘blueprint’ for a successful lesson or two?

How Computers Work – Lesson 3 How many places are there in the memory? Find a definition for accumulate Find out what an accumulator does in a computer What is a bus in a computer? What does opcode 6 do? What does opcode 3 do? Instruction 615 means do opcode 6 and the address is 15 – no choice, just go straight to memory 15 now. What does instruction 107 mean? What is the opcode for stopping a program? What is the opcode for loading data from memory into the accumulator

INPUT – write the input directly to the accumulator OUTPUT – draw a monitor and write in it ACCUMULATOR – write in the acc to do your maths. Run through Program 1 What does this simple program do?
