Choose the option that

gives correct information about CLC (Chemical Looping Combustion).

CLC is an advanced

Carbon Sequestration method.

During CLC, although

CO

₂ generated does not get mixed up with N₂

, it is mixed

up with water vapour that is very difficult to separate.

During CLC, N₂

and unused Oxygen come out of the air reactor.

CLC can be easily carried

out using any metal oxide.

Assume the 5 state process model. Suppose 13 processes have been admitted from the "new" state and are all executing on a system with a single CPU, where 9 of these processes make I/O requests. Assume that at any given time, one of these processes is assigned to the CPU. Based only on this information, before any of these processes terminate, what is the minimum number of processes that can be in the:
1) ready state;
2) blocked state?

Suppose 20-bit instructions are copied to a CPU's instruction register, and suppose that each instruction dedicates the first 6 bits for the "opcode", with the remaining bits for specifying a memory location. What is the total number of possible memory locations that could be referenced by these instructions?
