CPU scheduling refers to the process of assigning available processor time to different processes based on their priority and other factors. The goal is to ensure that critical tasks, which require exclusive access to the CPU, are completed promptly while preventing less important tasks from being starved to death.
Deadlock is a scenario in which multiple processes are waiting for resources held by each other, creating a circular dependency that prevents any progress. Deadlocks can be caused by various factors, including resource sharing, circular dependencies, and priorities that favor specific processes.
Here's a breakdown of how CPU scheduling and deadlocks differ:
CPU scheduling: Focuses on assigning time to processes based on their priorities and resource requirements.
Deadlock: Describes a situation where multiple processes are waiting for resources held by each other, creating a deadlock.
Here are some key points to remember about CPU scheduling and deadlocks:
Different scheduling algorithms exist, each with its own strengths and weaknesses.
Deadlocks are highly detrimental to system performance as they prevent processes from making progress.
They require careful analysis and management to prevent and mitigate.
Various deadlock prevention and avoidance mechanisms exist, including resource ordering, priority scheduling, and deadlock avoidance algorithms.
Examples:
CPU scheduling: Different scheduling algorithms like Round Robin and Priority scheduling assign time to processes based on their priorities.
Deadlock: Two processes, A and B, are waiting for each other to release a resource held by the other. This creates a deadlock where neither process can make progress.
By understanding CPU scheduling and deadlock mechanisms, we can effectively manage resource allocation and prevent system crashes caused by deadlocks
