Mission critical systems are made to avoid inability to complete the overall system, project objectives or one of the goals for which the system was designed. Examples of mission-critical systems are a navigational system for a spacecraft, software controlling a baggage handling system of an airport, etc. [ 2 ] [ 1 ] [ 3 ]
A Transaction Processing System (TPS) is an information system that collects, stores, modifies, and retrieves the data transactions of an enterprise. Transaction processing systems also attempt to provide predictable response times to requests, although this is not as critical as real-time systems.

An example of a safety critical system is a chemical manufacturing plant control system. Mission critical system and business critical system are similar terms, but a business critical system fault can influence only a single company or an organization and can partially stop lifetime activity (hours or days).
In engineering and systems theory, redundancy is the intentional duplication of critical components or functions of a system with the goal of increasing reliability of the system, usually in the form of a backup or fail-safe, or to improve actual system performance, such as in the case of GNSS receivers, or multi-threaded computer processing.
A safety-critical system [2] or life-critical system is a system whose failure or malfunction may result in one (or more) of the following outcomes: [3] [4] death or serious injury to people; loss or severe damage to equipment/property; environmental harm
A mixed criticality system is a system containing computer hardware and software that can execute several applications of different criticality, such as safety-critical and non-safety critical, or of different safety integrity level (SIL). Different criticality applications are engineered to different levels of assurance, with high criticality ...
