The new state is the first state of a process when it is created but not yet ready to run.

2fill in blank

medium

Complete the code to represent the state when a process is waiting for CPU time.

Operating Systems

process_state = "[1]"  # The state when a process is ready to run but waiting for CPU

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Choosing 'waiting' which means waiting for I/O, not CPU.

Selecting 'terminated' which means the process has finished.

The ready state means the process is prepared to run but is waiting for the CPU to become available.

3fill in blank

Fix the error in the code to show the state when a process is actively executing instructions.

Operating Systems

💡 Hint

Common Mistakes

Choosing 'ready' which means waiting to run, not running.

Selecting 'waiting' which means waiting for I/O.

The running state means the process is currently executing on the CPU.

4fill in blank

hard

Fill both blanks to represent the state when a process is waiting for an event and the state when it has finished execution.

Operating Systems

if event_not_occurred:
    process_state = "[1]"
else:
    process_state = "[2]"

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Mixing up 'ready' and 'waiting' states.

Confusing 'running' with 'terminated'.

The waiting state is when a process waits for an event like I/O completion. The terminated state means the process has finished execution.

5fill in blank

hard

Fill all three blanks to create a dictionary mapping process states to their descriptions.

Operating Systems

process_states = {
    "new": "[1]",
    "ready": "[2]",
    "terminated": "[3]"
}

Drag options to blanks, or click blank then click option'

AProcess is created but not ready

BProcess is prepared to run

CProcess has finished execution

DProcess is waiting for CPU

💡 Hint

Common Mistakes

Confusing 'ready' with 'waiting'.

Mixing descriptions of 'new' and 'terminated'.

This dictionary explains key process states: new means just created, ready means prepared to run, and terminated means finished.
