====== Inter-Process Communication (IPC) ======
[[dido:public:ra:xapend:xapend.a_glossary:start| Return to Glossary ]]

**Inter-Process Communication (IPC)** is a mechanism that allows the exchange of data between processes. By providing a user with a set of programming interfaces, **IPC** helps a programmer organize the activities among different processes. **IPC** allows one application to control another application, thereby enabling data sharing without interference.

**IPC** enables data communication by allowing processes to use segments, semaphores, and other methods to share memory and information. **IPC** facilitates efficient message transfer between processes. The idea of **IPC** is based on Task Control Architecture (TCA). It is a flexible technique that can send and receive variable length arrays, data structures, and lists. It has the capability of using [[dido:public:ra:xapend:xapend.a_glossary:p:publish-subscribe]] and [[dido:public:ra:xapend:xapend.a_glossary:c:client-server]] data-transfer paradigms while supporting a wide range of operating systems and languages.
