FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Security issues arise from external intrusions while reliability issues come from internal factors such as cyber elements’ random failures and malfunctions. Security is a shell that protects the system from external intrusions, while reliability deals with the internal functioning of the system, as shown in Fig.

Detailed explanation-2: -Reliability is defined as the probability that a product, system, or service will perform its intended function adequately for a specified period of time, or will operate in a defined environment without failure.

Detailed explanation-3: -Definition(s): The ability of a system or component to function under stated conditions for a specified period of time.

Detailed explanation-4: -Design for reliability ensures that products and systems perform a specified function within a given environment for an expected lifecycle. DfR often occurs at the design stage-before physical prototyping-and is often part of an overall design for excellence (DfX) strategy.
