In computer science, functional programming is a programming paradigm where programs are constructed by applying and composing functions. It is a declarative programming paradigm in which function definitions are trees of expressions that map values to other values, rather than a sequence of imperative statements which update the running state ...

The Functional Safety process is focused on identifying functional failure conditions leading to hazards. Functional Hazard Analyses / Assessments are central to determining hazards. FHA is performed early in aircraft design, first as an Aircraft Functional Hazard Analysis (AFHA) and then as a System Functional Hazard Analysis (SFHA).
The software and operating system used to run a domain controller usually consists of several key components shared across platforms.This includes the operating system (usually Windows Server or Linux), an LDAP service (Red Hat Directory Server, etc.), a network time service (ntpd, chrony, etc.), and a computer network authentication protocol (usually Kerberos).

Functional levels of a manufacturing control operation The key attribute of a SCADA system is its ability to perform a supervisory operation over a variety of other proprietary devices. Level 0 contains the field devices such as flow and temperature sensors, and final control elements, such as control valves .
In molecular biology, a protein domain is a region of a protein's polypeptide chain that is self-stabilizing and that folds independently from the rest. Each domain forms a compact folded three-dimensional structure. Many proteins consist of several domains, and a domain may appear in a variety of different proteins.
The Functional safety focus is on ensuring safety critical functions and functional threads in the system, subsystem and software are analyzed and verified for correct behavior per safety requirements, including functional failure conditions and faults and appropriate mitigation in the design.
Taxonomies are often represented as is-a hierarchies where each level is more specific than the level above it (in mathematical language is "a subset of" the level above). For example, a basic biology taxonomy would have concepts such as mammal , which is a subset of animal , and dogs and cats , which are subsets of mammal .
