The hexagonal architecture, or ports and adapters architecture, is an architectural pattern used in software design. It aims at creating loosely coupled application components that can be easily connected to their software environment by means of ports and adapters. This makes components exchangeable at any level and facilitates test automation ...
The term is also used when software/hardware is changed to make them usable in different environments. [1] [2] Software is portable when the cost of porting it to a new platform is significantly less than the cost of writing it from scratch. The lower the cost of porting software relative to its implementation cost, the more portable it is said ...
In computer networking, a port or port number is a number assigned to uniquely identify a connection endpoint and to direct data to a specific service. At the software level, within an operating system, a port is a logical construct that identifies a specific process or a type of network service.
Port numbers are categorized into three basic categories: well-known, registered, and dynamic or private. The well-known ports are assigned by the Internet Assigned Numbers Authority (IANA) and are typically used by system-level processes. Well-known applications running as servers and passively listening for connections typically use these ports.
Software portability may involve: Transferring installed program files to another computer of basically the same architecture. Reinstalling a program from distribution files on another computer of basically the same architecture. Building executable programs for different platforms from source code; this is what is usually understood by "porting".
[2]: 55 OISCs have been recommended as aids in teaching computer architecture [1]: 327 [2]: 2 and have been used as computational models in structural computing research. [3] The first carbon nanotube computer is a 1-bit one-instruction set computer (and has only 178 transistors). [4]
A network socket is a software structure within a network node of a computer network that serves as an endpoint for sending and receiving data across the network. The structure and properties of a socket are defined by an application programming interface (API) for the networking architecture.
Software Architecture Style refers to a high-level structural organization that defines the overall system organization, specifying how components are organized, how they interact, and the constraints on those interactions. Architecture styles typically include a vocabulary of component and connector types, as well as semantic models for ...
