In this tutorial, we are going to learn java program to find the factorial of the number given as input from the user using for loop. Problem Statement For any Input numbers given by the user, we have to calculate the factorial of that numbers. For example What is the Factorial of a Number? The … Read more
In this tutorial, we are going to learn a writing the java program to find the average of numbers using while loop. In previous tutorial we have seen the different way to find Average of number Problem Statement For any sequence of input numbers, we have to calculate the average of the input numbers from … Read more
In this tutorial, we are going to learn a writing java program to find the average of numbers given as input from the user. This program is little bit different from the previous Average program, Where we have calculated the average of Integer array in java. Problem Statement For any sequence of input numbers that … Read more
In this tutorial, we are going to learn a writing java program to find the average of given numbers. In this program basically, we will not take any user input. We have an integer array so we will iterate the integer array and then calculate the average number. Problem Statement For any given sequence of … Read more
A deadlock is a condition where each of the processes is waiting for a resource which is allotted to other processes. In this case, the process gets computed after the resource it requires is controlled by other processes, which is also looking for some other resource to be issued. For example, suppose two freight trains … Read more
Preemptive Scheduling Algorithm Here, a scheduler can preempt a running low-priority process at any time when a high-priority process enters a ready state. In preemptive systems, the OS takes the processor away from a running process. If the algorithm assumes one of the following circumstances, it is a preemptive algorithm – When a process transitions … Read more
There are different criteria for the CPU scheduling algorithm. CPU scheduling algorithms Criteria are CPU utilization: The main purpose of every scheduling algorithm is to keep the CPU busy. The utilization of the CPU can range from 0 to 100. CPU utilization is the percentage of the time interval in which the processor is busy … Read more
The oracle database is a centralized repository where data is stored. The Oracle database has a physical structure that is visible to the operating system and is made up of the Operating system’s files and logical structure that is recognized by the oracle server.
