Which tasks are the memory manager responsible for (as a part of the Operating System)

• Swapping applications and data between RAM and virtual memory

• Allocated sections of memory to applications

• Communicating with peripheral devices connected to the computer

• Allows the end user to control the computer effectively

Which of the following memory and CPU management functions does the OS perform in order to allow the system to multitask

• Each application is allocated a different memory space so that their data does not interfere with each other

• The OS moves unused parts of memory to storage and swaps it out as necessary

• The OS splits CPU cycles up between open applications

• The OS Prioritises processes so that instructions are executed in an efficient order
