How many processes can be in each of ready running and blocked at same time?

The number of processes in each state—ready, running, and blocked—depends on the system's architecture and resource availability. Typically, there can be multiple processes in the ready state, as they are waiting for CPU time. Only one process can be in the running state at any given moment in a single-core CPU, while in a multi-core CPU, multiple processes can run concurrently. The blocked state can also accommodate multiple processes, as they wait for specific resources to become available.
