Extensibility is divided into two types&colon; Browser extensibility and content extensibility. Thus, good modularity and abstraction leading to easy maintenance and extensibility are achieved. Forth is a simple, yet extensible language; its modularity and extensibility permit writing significant programs. A pluggable macro architecture allows for even more extensibility and flexibility. This project is a new implementation of wxPython, focused on improving speed, maintainability and extensibility. Newer WMO code forms are designed for portability, extensibility and universality. These protein fibers give the dermis its properties of strength, extensibility, and elasticity. The differences are based on the trade-offs between flexibility and extensibility vs latency and overhead. They exhibit a unique combination of high tensile strength and extensibility (ductility). When TIFF was introduced, its extensibility provoked compatibility problems. Modern operating systems support extensibility through device drivers and loadable kernel modules. The early development of "OpenTTD" focused on restructuring the code to improve readability and extensibility. Forward compatibility is not the same as extensibility. To achieve such simplicity, thin clients sometimes lag behind desktop PCs in terms of extensibility. Its purpose is to provide extensibility, neutrality, verbosity and independence.
