Processor and Process Algorithm

1. A process holds a resource without releasing it, waiting for another process to release a required resource.

Example: A process holds a lock on a shared file until it receives a signal from another process indicating it can proceed.

 2. Only one process can access a dedicated resource at a time.

3. Processes are stuck in a deadlock, each waiting for another process to release a resource.

Example: Process A is waiting for a resource held by process B, while process B is waiting for a resource held by process C, and so on, until process N is waiting for a resource held by process A.

 

 4. Resources cannot be temporarily taken away from a process.

 

 Example: Once a process acquires a printer, it cannot be interrupted or have the printer assigned to another process until it finishes printing.

 

 

  5. An algorithm developed by Edsger for resource allocation and deadlock avoidance. It tests for safety by simulating the allocation of maximum possible amounts of all resources.

 Example: In a banking system, the Banker's Algorithm can be used to ensure that loans are allocated in a way that avoids deadlock and ensures resource availability for all customers.

 6. is a scheduling method used by operating systems to allocate tasks to processes

 The main idea behind this is to prioritize the process that is closest to completing its task.

 7. a scheduling algorithm used in computing systems, particularly in CPU scheduling.

 It means that the tasks or processes are executed in the order they arrive or request the CPU, and the one that arrives first is served first.

 8. is a method that prioritizes tasks based on their importance, ensuring higher priority tasks are executed first.

 This approach is also utilized in technology systems to optimize resource allocation and task management.

 9. is a scheduling algorithm that prioritizes the execution of processes based on their shortest execution time. It can be implemented as either preemptive or non-preemptive.

 This algorithm reduces the average waiting time for other processes and enhances job output by executing shorter jobs first.

 

  1O. Is a basic and widely used algorithm for task scheduling, particularly in multitasking systems.

 The algorithm ensures that each task gets an equal opportunity, preventing starvation and promoting fairness.
