WJEC 1.5.1 Systems Software - Managing Resources

Which of the following does an operating system not do

• Manages memory (RAM)

• Manages printing using spooling

• Manages the ALU

• Manages security

An operating system manages peripherals such as input and output devices. In doing so what does the operating system do?

• Ensures that different processes can utilise the CPU and do not interfere with each other or crash

• Allows creation and deletion of user accounts

• Communicates with and receives data input to a keyboard/mouse/other valid input device

• Ensures that programs/data do not corrupt each other

An operating system manages memory. In doing so what does the operating system do?

• On a multi-tasking O/S ensure that all tasks appear to run simultaneously

• Allows users to logon and change passwords

• Communicates with and sends data output to a printer/monitor/other valid output device

• Ensures that all programs and data including itself is stored in correct memory locations

An operating system manages printing using spooling. In doing so what does the operating system do?

• Data is stored on hard disc/in memory/stored in a queue

• Ensures that data is stored and can be retrieved correctly from any disk drive

• Ensures that all programs and data including itself is stored in correct memory locations

• Communicates with and receives data input to a keyboard/mouse/other valid input device

An operating system manages printing using spooling. In doing so what does the operating system do?

• Document is printed when printer is free/in correct order

• Ensures that data is stored and can be retrieved correctly from any disk drive

• Ensures that all programs and data including itself is stored in correct memory locations

• Communicates with and receives data input to a keyboard/mouse/other valid input device
