Interprotsessiline

Interprotsessiline is an Estonian term describing interprocess communication and coordination between separate processes within a computing environment. It covers the mechanisms by which processes exchange data, synchronize actions, and manage shared resources, either on a single machine or across networked systems. The concept is central to operating systems, software architecture, and distributed applications.

Key mechanisms and patterns include:

- Local IPC primitives: pipes, named pipes (FIFO), message queues, shared memory, semaphores, signals

- Networking and RPC: sockets, remote procedure calls, HTTP/REST, message brokers (MQTT, AMQP)

- High-level frameworks: D-Bus, XPC, Windows communication APIs

- Data formats and messaging: JSON, XML, Protocol Buffers; publish-subscribe and request-response styles

Interprotsessiline encompasses both local IPC on a single host and distributed communication across machines. It supports synchronous patterns, where a caller waits for a response, and asynchronous patterns, where messages are exchanged without blocking. Correct use requires attention to ordering guarantees, reliability, security, and access control.

Common examples include Unix-like systems using pipes after process creation; Windows environments with named pipes or mailslots; Linux desktop environments using D-Bus; and microservice architectures employing HTTP or messaging buses for inter-service communication. Potential challenges include synchronization issues, deadlocks, performance overhead, and ensuring proper permissions across processes or services.
