# Inter-Process Communication (IPC) with the FSFW
IPC is a necessary tool to let software entities communicate with each other. In general, for
any Software, there are two primary ways for software entities to communicated with each other:
1. Shared Memory. If memory is shared between threads or tasks, memory access needs to be protected
with a lock, also commonly called Mutex.
2. Message Passing. Usually, OSes provide some way of passing messages between threads safely.
