functions of cpu

cpu consists of ALU, Control unit assisted by a set of registers. control unit sends control signal to synchronize the flow of information between the different units of the computer and helps to fetch, decode and execute the instructions from memory. alu performs all the arithmetic and logical operations in the instructions. registers help in quick transfer of data to and from cpu.
