MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Explanation: All fault-tolerant techniques rely on extra elements introduced into the system to detect & recover from faults.

Detailed explanation-2: -Fault tolerance is the property that enables a system to continue operating properly in the event of the failure of (or one or more faults within) some of its components.

Detailed explanation-3: -Bugs in software can arise from mistakes and errors made in interpreting and extracting users’ requirements, planning a program’s design, writing its source code, and from interaction with humans, hardware and programs, such as operating systems or libraries.

Detailed explanation-4: -Control reconfiguration is an active approach in control theory to achieve fault-tolerant control for dynamic systems. It is used when severe faults, such as actuator or sensor outages, cause a break-up of the control loop, which must be restructured to prevent failure at the system level.
