Loose coupling is an important aspect of computer systems design, allowing independent components to share information. Examples include USB ports and service-oriented architecture. The approach offers flexibility but can be slower than tightly coupled systems.
Proper systems design is an important aspect of large computer systems. It requires a deep understanding of network hardware, software, and protocols. Loose coupling is an architectural approach that allows independent computer components to share information. It is used in software and hardware design to make it easier for computer specialists to manage equipment.
One of the best examples of loosely coupled designs is the Universal Serial Bus (USB) port on computers. This universal port allows multiple types of hardware to connect to a computer using a standard protocol. USB has become a standard device and is often used by printers, cameras and many other external computing devices.
The main advantage of loose coupling is hardware and software flexibility. The computer systems used by organizations quickly become a series of interchangeable components that can work together to create a large set of business components.
Loosely coupled computer software consists of many interchangeable components. This system design approach is widely used by large companies using the Internet. Some examples include internet games, social networking and chat rooms. These individual components are made available to the public as separate modules that can be used as needed.
Service-oriented architecture is a good example of loosely coupled design in practice. This approach requires developers to build small agile components specialized for a specific task. These components are loosely coupled to external programs using a standard protocol or generic interface.
This architecture is common in mobile application development because it uses small, flexible components that require fewer computer resources. Most modern cell phones use this architecture for games and other programs. Consumers can select the modules they want and can easily add new features to mobile devices.
Another benefit of the loosely coupled design is the software independent nature of the system. A loosely coupled application can run on multiple types of hardware and operating systems. This makes it more expandable and flexible. It also makes the software available to a larger group of potential customers.
The loose fit has some disadvantages. A loosely coupled program is more generic and modular with several interconnected components. While this type of program is extremely flexible, it is usually slower than a tightly coupled system. When designing a program, it is important to determine when to use loose coupling.
