Select the correct registers of a CPU:
PC(Program Counter)
ACC(Accumulator)
MAR(Memory Address Register)
MDR(Memory Data Register)
CIR(Current Instruction register)
This register stores the current instruction being decoded and executed
PC(Programming Counter)
ACC(Accumulator)
MAR(Memory Address Register)
MDR(Memory Data Register)
CIR(Current Instruction register)
This register is used when carrying out ALU calculations; it stores data temporarily during the calculations:

What is the meaning of system clock cycle?
A clock cycle, also known as a machine cycle or a clock tick, is the basic unit of time in a computer's central processing unit (CPU). It represents one complete operation of the CPU, including fetching, decoding, executing, and storing data per second.
A clock cycle refers to how many cores a CPU has inside of it.
