18 RELIABILITYSystems ReliabilityA system consists of components which determine whether or not itwill work. There are various types of configurations of the componentsin different systems. Series SystemThis is a system in which all the components are in series and theyall have to work for the system to work. If one component fails,the system fails. Parallel SystemThis is a system that will fail only if they all fail. Series-Parallel SystemThis is a system where some of the components in series are repli-cated in RELIABILITY of Series SystemExamples1. A simple computer consists of a processor, a bus and a computer will work only if all three are functioning probability that the processor is functioning is , that thebus is functioning , and that the memory is functioning is.

8.2 Reliability of a Parallel System Systems with parallel structure have built in redundancy. Components are backed up, and the system will work even if some of these cease to function. Examples 1. A system consists of 5 components in parallel. If each component has a reliability of 0.97, what is the overall reliability of the system? input− ...

10 GEOMETRIC DISTRIBUTION EXAMPLES: 1. Terminals on an on-line computer system are at-tached to a communication line to the central com-puter system. The probability that any terminal is ready to transmit is 0.95. Let X = number of terminals polled until the first ready terminal is located. 2. Toss a coin repeatedly. Let X = number of tosses ...
