ABSTRACT

This chapter presents various important aspects of computer, Internet, and robot system reliability. As computer failures can, directly or indirectly, affect our day-to-day life, their reliability has become an important issue to the population at large. Generally, for computer system reliability modeling and evaluation, an effective method to classify computer-related faults is on the basis of their duration. Internet reliability has become very important to the global economy and other areas, because Internet failures can result in millions of dollars in losses and interrupt the day-to-day routines of its vast number of end users around the globe. Experiences, over the years, clearly indicate that many Internet-related services suffer faults, and a quick detection of these faults could be a critical factor to improve system availability. Robot reliability may simply be described as the probability that a robot will carry out its specified function satisfactorily for the stated time interval when used according to the designed conditions.
