What is the difference between the arithmetic operations and logical operations which are performed by the CPU?
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.
Difference between an arithmetic shift operation and a logical shift operation?
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).
Which unit of computer performs arithmetic and logical functions?
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.
What performs arithmetic comparison and logical operations?
ALU
What is the difference between arithmetic operations and logical operations?
Arithmetic operations involve mathematical calculations such as addition, subtraction, multiplication, and division, which manipulate numerical values. Logical operations, on the other hand, involve evaluating conditions or expressions to determine true or false outcomes. Arithmetic operations deal with numerical values, while logical operations deal with Boolean values (true or false).
