Encyclopaedia of Computer Science (In 5 Volumes)

In this set of five volumes, efforts have been made to incorporate all the relevant knowledge that has been discovered so far in the field of computer and its impact on education. It is based on the following premises. The changes in the home, work place and society in general will cause a shift or expansion in the kinds of educational services that are needed and demanded. Educational system in the computer age is bound to undergo revolutionary changes. The Logon procedure involves two major steps: (1) the user connects the terminal with the system and (2) then identifies himself or herself as a legitimate user. The industry trend is toward increasingly complex environments, involving multiple media types, multiple protocols and often inter connection to “unknown” net works. Unknown networks may be defined as a transit network belonging to a internet service provider (ISP) or a telco that inter connects our private networks. In these unknown networks one does not have control of such factors as delay, media types or vendor hardware. Information theory is concerned with the problem of how to measure changes in information or knowledge content. It is based on the fact that we can represent our experience by the use of symbols like the alphabet, pictures, etc. An existential view of information is relativistic and states that information per see is something imperceptible. Software development is dynamic and always undergoing major change. The methods we will use in the future no doubt will differ significantly from those currently in practice. We can anticipate which methods and tools are going to succeed, but we can not predict the future. Factors other than just technical superiority will likely determine which concepts prevail. It is hoped that the encyclopaedia will provide all the relevant knowledge on computers and computer education at one place and will fulfil a long felt need of an encyclopaedia in this area. It is hoped that the encyclopaaedia will prove to be of immense value to the educationists, students, teachers and educational planners and administrators and researchers as well.
