ANALYSIS OF THE WAY OF SERVICE IN A COMPLEX COMPUTER PROCESS WITHIN AN EDUCATIONAL PLATFORM (WWW.COMUNICARE.RO)

With the passage of time, ICT has become accessible and used by more and more individuals without technical knowledge or skills. At the same time, the complexity of the instruments has grown enormously. Now those who acquire and use technology are not just IT specialists but also educational content creators, managers, teachers, instructors and students. These rapid changes have often left behind those who have failed to adapt and document properly. Lack of information and fear of the unknown often creates confusion and hostility towards the use of ICT in education. Processes running on multiple systems vary over time. For this reason, there is no static set of processes (and time intervals) that can be used for deterministic modelling. However, the CPU distribution and grid-generated bursts can be determined. These distributions can be measured and then approximated or estimated [1]. The results are mathematical formulas that describe the likelihood of occurrence of an event, for example the probability of the system being in a stable state. Usually the distribution is exponential, Poisson type, and is described by its average value. Similarly, the timing of the processes arriving in the system must be provided. From these two distributions the average values of productivity, usage, waiting time can be calculated using queuing networks analysis. Queuing networks are called open when the jobs can enter or leave the network by any node [2]. If the jobs cannot leave or enter the network, it is called closed, and the number of jobs on the network remains constant. Therefore, a network where a new job is admitted every time an old job leaves the system can be considered a closed network [3].
