Computers are having a rapidly growing impact on business. One of the results of this is an emerging need for fault tolerance in some of these computers.
Very basically, fault tolerance means the ability to detect and survive a computer fault and continue processing.
The objectives of this report are to:-
1 .Discuss the relevance of computer fault tolerance to business.
2.To investigate whether there are differences between Australian industries in their perceived importance of fault to tolerance to their companies’ computer policies. (To be clone by survey.)
The report will have the following format:-
1.Consider the current relevance of computer fault tolerance to business.
2.Describe applications of "fault tolerant" computers.
3.Discuss the theoretical basis of fault tolerant techniques.
4.Provide examples of commercial systems available in Australia.
5.Present and discuss the survey and its results.
Fault tolerance is not a single quantum that is either present or absent in a computer. Rather, it consists of a plethora of techniques which can be used to improve computer reliability.
Fault tolerant techniques can be used to counter the problems of computer vulnerability but they are not sufficient alone. Other techniques are also applicable, for example, offsite data storage.
The survey did show a trend towards differences in various industries' perceptions of their needs for computer fault tolerance in their computer systems - the Banking/Finance and Chemical Products Industries respondents felt that this issue was more important than the other industries' respondents.
There was also a trend towards other differences between the industries surveyed. These will be presented in Chapter 6.
Many of the respondents volunteered comments in the space provided for this. These comments were interesting and gave some insights into the respondents' opinions regarding fault tolerance and its relevance to both their companies and business in general.
