Encourages code reusability and encapsulation.

Contains multiple components, each handling part of the module's functionality.

Easily replaceable and updateable due to its specific functionality.

Presents a unified interface to the rest of the system, despite internal complexities.

A part or element of a larger whole, especially a part of a machine or vehicle

A standardized, often interchangeable component of a system or construction that is designed for easy assembly or flexible use

Constituting part of a larger whole; constituent

(Architecture) A length used as a unit of measurement or as a standard for determining the proportions of a building.

A constituent element, as of a system.

(Electronics) A self-contained assembly of electronic components and circuitry, such as a stage in a computer, that is installed as a unit.

A part of a mechanical or electrical complex.

(Computers) A portion of a program that carries out a specific function and may be used alone or combined with other modules of the same program.

(Mathematics) One of a set of two or more vectors having a sum equal to a given vector.

A self-contained unit of a spacecraft that performs a specific task or class of tasks in support of the major function of the craft.

Being or functioning as a constituent or an ingredient.

A unit of education or instruction with a relatively low student-to-teacher ratio, in which a single topic or a small section of a broad topic is studied for a given period of time.

A smaller, self-contained part of a larger entity. Often refers to a manufactured object that is part of a larger device.

(Mathematics) An algebraic system that resembles a vector space, except that the set of scalars forms a ring and not necessarily a field.

Making up a larger whole; as a component word.

(Biology) A unit of modular growth, such as a coral polyp.

Made up of smaller complete units in combination; as a component stereo.

(Archaic) A standard or unit of measurement.

Serving, or helping, to form; composing; constituting; constituent.

A self-contained component of a system, often interchangeable, which has a well-defined interface to the other components.

A constituent part; an ingredient.

(architecture) A standard unit of measure used for determining the proportions of a building.

An abstract part of something;

(programming) A section of a program; a subroutine or group of subroutines.

Something determined in relation to something that includes it;

A unit of education covering a single topic.

An artifact that is one of the individual parts of which a composite entity is made up; especially a part that can be separated from or attached to a system;

A pre-prepared adventure scenario with related materials for a role-playing game.

An abelian group equipped with the operation of multiplication by an element of a ring (or another of certain algebraic objects), representing a generalisation of the concept of vector space with scalar multiplication.

A fractal element.

(music) A file containing a music sequence that can be played in a tracker (called also mod or music module).

(hydraulics) A contrivance for regulating the supply of water from an irrigation channel.

(astronautics) An independent self-contained unit of a spacecraft.

A model or measure.

The size of some one part, as the diameter of semi-diameter of the base of a shaft, taken as a unit of measure by which the proportions of the other parts of the composition are regulated. Generally, for columns, the semi-diameter is taken, and divided into a certain number of parts, called minutes (see Minute), though often the diameter is taken, and any dimension is said to be so many modules and minutes in height, breadth, or projection.

To model; also, to modulate.

One of the inherent cognitive or perceptual powers of the mind

Detachable compartment of a spacecraft

Computer circuit consisting of an assembly of electronic components (as of computer hardware)

A self-contained component (unit or item) that is used in combination with other components

A component is a distinct, functional unit within a system, designed to perform a specific task, emphasizing reusability and encapsulation.

Typically, a module is composed of multiple components; it organizes and groups these components into a larger, cohesive functionality.

Component reusability allows for the efficient reuse of code across different parts of a system, reducing redundancy and facilitating easier updates and maintenance.

Yes, components can be designed to be reusable across different modules, enhancing system flexibility and reducing development effort.

A module in software architecture is a larger, more complex grouping of components that encapsulates a domain of functionality, offering modularity and maintainability.

Modules are important because they help organize system architecture into manageable, coherent parts, simplifying development, maintenance, and scalability.

Modular design enhances system maintainability, scalability, and understandability by organizing complex functionalities into manageable parts.

The decision is based on the scope of functionality: specific, isolated functions are suited to components, while broader, cohesive functionalities suggest the need for a new module.

Components perform specific tasks within a module, and modules organize these components to provide broader system functionality, interacting through defined interfaces.

Modules can be designed to be interchangeable if they provide similar functionalities through a unified interface, though this depends on the system's architecture.

Components aim for minimal dependencies for ease of reuse, while modules manage internal dependencies among components but present a simplified interface externally.

Yes, a well-designed component can be part of multiple modules, provided it serves a purpose in each without compromising functionality.

Modules, with their unified interfaces and encapsulated functionalities, simplify system integration by providing clear, manageable points of interaction for external systems or other modules.

Components, through their reusability and encapsulation, directly contribute to system scalability by simplifying the addition of new functionalities and updates.

Updating a component can improve or alter the functionality of the module it belongs to, ideally without affecting the module's overall operation if designed with encapsulation in mind.
