Deadlock comes from contention between processes (or threads) for resources. So, to understand deadlock we need to understand resources.
Reusable resources
The resources that can be reused again. Examples include Processors, I/O channels, main and secondary memory, files, databases, and semaphores.
Consumable resources
The resources that are depleted after the use by a process. Examples include Hardware interrupts, Unix signals, pthread_cond_signal calls, messages, and information in I/O buffers.
