An arithmetic operation is dealing with data in a computational manner, adding subtracting, etc A logical operation would normally be regarded a a comparison and decision, though one school of though would include the literally 'logical operations' such as NOT, OR, AND, etc.
Arithmetic operations act on the values of numbers or expressions. Logical operations act on the truth-values of statements or equations.
Instead of being filled with all 0s, as in logical shift, when shifting to the right, the leftmost bit (usually the sign bit in signed integer representations) is replicated to fill in all the vacant positions (this is a kind of sign extension).
The ALU (arithmetic logic unit) An ALU loads data from input registres, an external Control Unit then tells the ALU what operation to perform on that data, and then the ALU stores its result into an output register. Other mechanisms move data between these registers and memory.

Arithmetic operations are addition,subtraction,multiplication,division.Logical operations are OR,AND NOT,NOR,NAND,XOR,XNOR.
The Arithmetic Logic Unit as suggested by the name carries out the arithmetic calculations of the computer.

Arithmetic logic unit
The unit that performs the arithmetic and logical operations within the processor is called the Arithmetic Logic Unit (ALU).
The ALU (arithmetic logic unit) An ALU loads data from input registres, an external Control Unit then tells the ALU what operation to perform on that data, and then the ALU stores its result into an output register. Other mechanisms move data between these registers and memory.
The Arithmetic Logic Unit (ALU) is the heart of a CPU. This is what allows the computer to add, subtract, and to perform basic logical operations.
