INTRODUCTION CPU Scheduling is the process by which an Operating System decides which programs get to use the CPU. The major current O/S all work pretty much alike‚ although there are many possible ways to decide this issue. First‚ one must understand that‚ although every computer task takes CPU time‚ some take lots and some take just a bit‚ and then use I/O devices‚ or wait for user input. When that happens‚ processes running on the computer usually release the CPU‚ and let other processes use

1. AIM: To write a C program to simulate the shortest job first algorithm with preemption. DESCRIPTION: For implementing SJF algorithm with preemption‚ we consider the arrival times of each process‚ the burst times of all the previously arrived processes. After the arrival of all the processes into the ready queue‚ the average waiting time and turn around time can be calculated by using the above algorithm. ALGORITHM: 1) start 2) read the no of processes to n 3) initialize i to 0 4) if

selects from the ready processes the next process to run and gives it the CPU. The long-term scheduler selects from the pool of processes that are waiting on disk and loads the selected processes into memory. These processes have not yet begun their execution. The medium-term scheduler takes processes that are currently in memory and selects those to be swapped out to disk. These processes will be swapped back in at a later point. This is done to improve process mix or because of memory requirements

Memories play an important role in our self-identity and without them we would being living in world that is completely unfamiliar to us. There are two main components to memory and those are short-term memory which has a limited and brief capability to hold and or store information whereas long term memory is virtually limitless in capacity and is more durable.

The function and process of perception can vary depending on a particular state of consciousness. Normal waking consciousness is a mental state that encompasses the thoughts‚ feelings‚ and perceptions that occur when we are awake and reasonably alert (Morris & Maisto‚ 2010‚ p.123). Since this state of mind expires after an amount of time‚ other forms of consciousness follow; whether naturally or self-induced. While sensory data is inevitable‚ the brain ’s interpretation and perception of such stimuli

properly securing the girth are vital parts to ensuring a safe ride. One of the utmost crucial steps when tacking up a horse is to check all the tack‚ or equipment‚ to make sure nothing is ripped‚ broken or out of place. This is a commonly skipped process because it can become very tedious. Verifying that there is no grass burrs‚ sticks or rocks in the saddle pad‚ is as straightforward as running a hand over the underside of the pad. Upon feeling a sharp or foreign object‚ be sure to remove it. If

Process Costing Characteristics of Process Manufacturing • Since each product within a product line passing through the processes would receive similar ‘‘doses’’ of materials‚ labor‚ and overhead‚ costs are accumulated by process. • Process costing works well whenever relatively homogeneous products pass through a series of processes and receive similar amounts of manufacturing costs Units are homogeneous and subjected to the same operations for a given process and each unit produced in a
