Study Notes
Deadlock in Operating Systems
- Deadlock is a situation where a set of processes are blocked because each process is holding a resource and waiting for another resource acquired by some other process.
Conditions for Deadlock to Happen
- There are four necessary conditions for deadlock to occur:
Mutual Exclusion
- Mutual Exclusion: a condition where two or more processes require exclusive access to a common resource.
Hold and Wait
- Hold and Wait: a condition where a process is holding a resource and waiting for another resource.
No Pre-emption
- No Pre-emption: a condition where a resource cannot be forcefully taken from a process holding it.
Circular Wait
- Circular Wait: a condition where a process is waiting for a resource held by another process, which in turn is waiting for a resource held by the first process, forming a circular chain of waiting processes.
