What are the disadvantages of FCFS scheduling?

Disadvantages: This scheduling method is nonpreemptive, that is, the process will run until it finishes. Because of this nonpreemptive scheduling, short processes which are at the back of the queue have to wait for the long process at the front to finish.

What is deadlock in DBMS?

In a database, a deadlock is a situation in which two or more transactions are waiting for one another to give up locks. For example, Transaction A might hold a lock on some rows in the Accounts table and needs to update some rows in the Orders table to finish.

What is CPU scheduling and its type?

CPU scheduling is a process which allows one process to use the CPU while the execution of another process is on hold(in waiting state) due to unavailability of any resource like I/O etc, thereby making full use of CPU. The aim of CPU scheduling is to make the system efficient, fast and fair.

Which scheduling algorithm is best?

Sometimes FCFS algorithm is better than the other in short burst time while Round Robin is better for multiple processes in every single time. However, it cannot be predicted what process will come after. Average Waiting Time is a standard measure for giving credit to the scheduling algorithm.

What is cluster scheduling?

Cluster scheduling involves grouping patients with similar exam types, conditions, or treatments, and scheduling them within a certain time block during the day.

Which scheduling algorithm is used in Windows 10?

Each queue can have its own scheduling algorithms. Priorities are assigned to each queue. ➢ Windows scheduled threads using apriority-based,preemptive scheduling algorithm. ➢ The scheduler ensures that the highest priority thread will always run.

What are the characteristics of a good scheduling algorithm?

Characteristics include Utilization of CPU, Response time, Throughput, Turnaround time, Waiting time and fairness. This algorithm keeps the CPU busy by using most of it.

What is SQL transaction?

A transaction is a logical unit of work that contains one or more SQL statements. A transaction is an atomic unit. The effects of all the SQL statements in a transaction can be either all committed (applied to the database) or all rolled back (undone from the database).

What are the 3 different types of scheduling queues?

Process Scheduling QueuesJob queue − This queue keeps all the processes in the system.Ready queue − This queue keeps a set of all processes residing in main memory, ready and waiting to execute. … Device queues − The processes which are blocked due to unavailability of an I/O device constitute this queue.

What is patient scheduling?
