The Von Neumann model for a computer system has several components that are used in the fetch-execute cycle. (a) One component is main memory. (i) Describe what is meant by main memory and how it is used in the Von Neumann model for a computer system. \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ [3] (ii) State two other components in the Von Neumann model for a computer system. 1 \_\_\_\_ 2 \_\_\_\_ [2] (b)Computer systems often use interrupts. Five statements are given about interrupts. Tick (✓) to show if each statement is True or False. | Statement | True (✓) | False (✓) | | :--- | :--- | :--- | | Interrupts can be hardware based or software based | | | | Interrupts are handled by the operating system | | | | Interrupts allow a computer to multitask | | | | Interrupts work out which program to give priority to | | | | Interrupts are vital to a computer and it cannot function without them | | | [5]
