An approach to consider computers and connected computer systems using structural, time, and information redundancies is proposed. An application of redundancy for reconfigurability and recoverability of computers and connected computer systems is discussed, gaining performance, reliability, and power-saving in operation. A paradigm of recoverability is introduced and, if followed, shifts connected computer systems toward real-time applications. Use of redundancy for connected computers is analysed in terms of recoverability, where two supportive algorithms of forward and backward tracing are proposed and explained. As an example, growth of mission reliability is formulated. View Full-Text
