Содержание слайда: Starter: Early Computers Did you know that the history of computers dates back to the 1800s? Place the following key events in the correct order on the timeline;

Содержание слайда: How Von Neumann Architecture changed the world of computers The very first computers could not store programs; they were input by setting switches. Jon Von Neumann developed the concept of the stored program computer in the 1940s. A Von Neumann based computer is one that; Uses a single processor. Uses one memory for both instructions and data. A von Neumann computer cannot distinguish between data and instructions. It ‘knows’ only because of the location of a particular bit pattern in RAM. Executes programs by doing one instruction after the next in a sequential manner using a fetch-decode-execute cycle.

Содержание слайда: How does Von Neumann Architecture work? Watch the video located on this webpage: http://www.bbc.co.uk/education/guides/zmb9mp3/revision/1 Answer the following questions: (Handout 1)

Содержание слайда: Von Neumann in detail: Components of the Processor

Содержание слайда: The CPU: Arithmetic & Logic Unit (ALU) The ALU carries out the following functions: Logical operations: Boolean operations, e.g. AND, OR and NOT Shift operations: The bits in a computer word can be shifted left or right by a certain number of places. Arithmetic operations: These include addition, subtraction, multiplication and division.

Содержание слайда: Task: ALU Operations Which of the ALU operations would be best suited for the following tasks: Logical, Shift or Arithmetic? (handout 2)

Содержание слайда: Task: ALU or Control Unit? (handout 3) Place the following statements into the correct category - ALU or Control unit:

Содержание слайда: Task: Von Neumann puzzle (handout 4) Learners to stick the pieces to create the Von Neumann Architectural block diagram. Learners who finish this activity before time should describe the Von Neumann architecture.

Содержание слайда: Fetch-execute cycle (handout 5) Learners to read about fetch-execute cycle followed by peer discussion Learners to attempt task in handout 6

Содержание слайда: Question and Answer Divide the learners in groups of 3-4. Groups to take turn in asking each other questions, related to the operations of the processor. You may adopt an awarding method to encourage competition.
