A tri-state type DIP switch can be in one of three positions (+, 0, −) which allows more codes than a binary DIP switch. For example, 8 pole tri-state DIP switches offer 6,561 (3 8) combinations/codes compared to 8 pole binary switches' 256 (2 8) combinations/codes. This makes them especially suitable for encoding devices such as a remote ...
For example, dependency injection can be used to externalize a system's configuration details into configuration files, allowing the system to be reconfigured without recompilation. Separate configurations can be written for different situations that require different implementations of components.
(Dependency injection is an example of the separate, specific idea of "inverting control over the implementations of dependencies" popularised by Java frameworks.) [4] Inversion of control is sometimes referred to as the "Hollywood Principle: Don't call us, we'll call you".
In object-oriented design, the dependency inversion principle is a specific methodology for loosely coupled software modules.When following this principle, the conventional dependency relationships established from high-level, policy-setting modules to low-level, dependency modules are reversed, thus rendering high-level modules independent of the low-level module implementation details.
A DIP is usually referred to as a DIPn, where n is the total number of pins, and sometimes appended with the row-to-row package width "N" for narrow (0.3") or "W" for wide (0.6"). For example, a microcircuit package with two rows of seven vertical leads would be a DIP14 or DIP14N. The photograph at the upper right shows three DIP14 ICs.
Adapter Java Design Patterns - Adapter; Delegation, strongly relevant to the object adapter pattern. Dependency inversion principle, which can be thought of as applying the adapter pattern, when the high-level class defines its own (adapter) interface to the low-level module (implemented by an adaptee class).

As an example, the 6800 includes an 8-bit direct addressing mode used to make code smaller and faster; instead of a memory address having 16 bits and thus requiring two bytes to specify, commonly used variables could be located within a 256-byte window (called the "direct page" on the 6800 or "zero page" on the 6502 because of its location at ...
