Answer 2

Answer:  

Yes, ALU is an independent unit because it performs the functions independently.

Explanation:

Arithmetic Logic Unit is an abbreviated form of ALU. It is a circuit that is used to perform mathematical functions such as arithmetic and logical functions. ALU is a component of the 'central processing unit' of a computer. Advanced CPU has potential ALUs to perform 'mathematical calculations'.

The functions of a central processing unit are executed by one or more Arithmetic logic units that fill the data from input registers. Small storage available as segment of a CPU is called registers. ALU performs the functions on the given input data and it keeps the output in the output register.
