1. Resource contention: Deadlock can occur when multiple processes are competing for the same resources, such as memory, CPU time, or I/O devices. If each process holds a resource that another process needs, a deadlock can occur where neither process can proceed.
2. Circular wait: Deadlock can also occur when processes are waiting for each other to release resources in a circular chain. For example, Process A is waiting for a resource held by Process B, which is waiting for a resource held by Process C, and so on, until Process A is waiting for a resource held by Process A.
3. No preemption: Deadlock can occur when processes cannot be preempted, meaning that once a process acquires a resource, it cannot be forcibly taken away. If a process is holding a resource that another process needs, but cannot be preempted, a deadlock can occur.
4. Mutual exclusion: Deadlock can also occur when processes are unable to access resources simultaneously due to mutual exclusion. If a process holds a resource and cannot be interrupted, other processes that need that resource may be unable to proceed, leading to a deadlock.

Conditions for Deadlock Complexity in Operating Systems
1. Resource Scarcity: When resources are limited and multiple processes are competing for the same resources, it can lead to a deadlock situation where no process can proceed.
2. Non-Preemptive Scheduling: If the operating system does not allow a higher-priority process to interrupt and preempt a lower-priority process holding a resource, it can result in deadlock.
3. Circular Waiting: When a chain of processes is created where each process is waiting for a resource held by the next process in the chain, a circular waiting deadlock occurs.
4. Mutual Exclusion: When processes are allowed to access shared resources only one at a time, it can create a situation where multiple processes are waiting for the same resource, leading to deadlock.
