A stub is the stock representing the remaining equity in a corporation left over after a major cash or security distribution from a buyout, a spin-out, a demerger or some other form of restructuring removes most of the company's operations from the parent corporation. A stub may retain the name of the original corporation, or in some cases may take another name as part of the restructuring.

In microwave and radio-frequency engineering, a stub or resonant stub is a length of transmission line or waveguide that is connected at one end only. The free end of the stub is either left open-circuit or (always in the case of waveguides) short-circuited. Neglecting transmission line losses, the input impedance of the stub is purely reactive; either capacitive or inductive, depending on the electrical length of the stub, and on whether it is open or short circuit. Stubs may thus function as capacitors, inductors and resonant circuits at radio frequencies.

Stubs work by means of standing waves of radio waves along their length. Their reactive properties are determined by their physical length in relation to the wavelength of the radio waves. Therefore stubs are most commonly used in UHF or microwave circuits in which the wavelengths are short enough that the stub is conveniently small. They are often used to replace discrete capacitors and inductors, because at UHF and microwave frequencies lumped components perform poorly due to parasitic reactance. Stubs are commonly used in antenna impedance matching circuits, frequency selective filters, and resonant circuits for UHF electronic oscillators and RF amplifiers.

Stubs can be constructed with any type of transmission line: parallel conductor line (where they are called Lecher lines), coaxial cable, stripline, waveguide, and dielectric waveguide. Stub circuits can be designed using a Smith chart, a graphical tool which can determine what length line to use to obtain a desired reactance.

A stub in distributed computing is a piece of code used for converting parameters passed during a Remote Procedure Call ( RPC).

The main idea of an RPC is to allow a local computer ( client) to remotely call procedures on a remote computer ( server). The client and server use different address spaces, so conversion of parameters used in a function call has to be performed, otherwise the values of those parameters could not be used, because of pointers to the computer's memory pointing to different data on each machine. The client and server may also use different data representations even for simple parameters (e.g., big-endian versus little-endian for integers.) Stubs are used to perform the conversion of the parameters, so a Remote Function Call looks like a local function call for the remote computer.

Stub libraries must be installed on client and server side. A client stub is responsible for conversion (Marshalling) of parameters used in a function call and deconversion of results passed from the server after execution of the function. A server skeleton, the stub on server side, is responsible for deconversion of parameters passed by the client and conversion of the results after the execution of the function.

Stub can be generated in one of the two ways:

1. ' Manually': In this method, the RPC implementer provides a set of translation functions from which a user can construct his or her own stubs. This method is simple to implement and can handle very complex parameter types.
2. Automatically: This is more commonly used method for stub generation. It uses an interface description language (IDL), that is used for defining the interface between Client and Server. For example, an interface definition has information to indicate whether, each argument is input, output or both — only input arguments need to be copied from client to server and only output elements need to be copied from server to client.

A server program that implements procedure in an interface is said to export the interface and a client program that calls procedures from an interface is said to import the interface. When writing a distributed application, a programmer first writes an interface definition using the IDL. We can then write the client program that imports the interface and the server program that exports the interface. The interface definition is processed using an IDL compiler to generate components that can be combined with client and server programs, without making any changes to the existing compilers. In particular, from an interface for each procedure in the interface, the appropriate marshalling and unmarshalling operations in each stub procedure and a header file that supports the data types in the interface definition. The header file is included in the source files of both the client and server programs,the client stub procedures are compiled and linked with the client program and the server stub procedures are compiled and linked with the server program. An IDL compiler can be designed to process interface definitions for use with different languages, enabling clients and servers written in different languages, to communicate by using remote procedure call To achieve the goal of semantics transparency designers have made RPC look like LPc using the concept of stubs that hide the actual RPC implementation from the programs the interface to the underlying RPC system.
