Interprocess Communication Basics Questions

Core mechanisms and trade offs for communication and coordination between processes and services. Topics include signals, anonymous and named pipes, message queues, local and network sockets, shared memory, and synchronization primitives such as semaphores and mutexes. Candidates should be able to compare synchronous and asynchronous patterns, discuss ordering and delivery guarantees, explain security and access control implications, and choose appropriate mechanisms based on latency, throughput, message size, and deployment topology.
