    Computer Security
    Yusuf, Musa; Fazekas, Gábor; DE--Informatikai Kar
    Security involves making sure the good guys get in and the bad guys stay out. Throughout the development of the computer, security has been an increasingly important consideration. Software has evolved to include security functions, and with advent of the internet and large networks, security has become a daily issue. In fact, security software is considered by many in the computer industry to be a necessary evil. At the core of any security software process is the fundamental proposition that the level of risk associated with electronic data (often called an information asset) is the product of the data’s value, threats and vulnerabilities. Understanding this risk and being able to determine its relative rating are key components of security. As the significance of any of these factors increases, the risk also increase. Conversely, reducing any of these factors will significantly reduce the relevant risk.

    Performance Modelling of Call Centres
    Yusuf, Musa; Sztrik, János; DE--Informatikai Kar
    Huge cost have been realised from the growing number of call Centres Company worldwide. There is benefit for customers as well as the multiple servers queuing system. I considered a case to serve the whole queue with a fix service rate, if there is a long queue of customers. If the customers in a queue could not reach up to the require numbers of customer to be serve as when they arrive in group then individually they could be served with different service rate. Call centres need to have an idea on how their agents are organised to have them fixed to each period to know how many agent would be needed for specified periods. To achieve a high performance there have to be an equilibrium between low waiting time and high quality services.
