With a logical shift the vacated bits are always filled with zeroes. With an arithmetic shift, a left shift will fill vacated bits with zeroes but a right shift fills the vacated bits with a copy of the most significant bit.
hardware,software and 3rd is data. explain in detail then this question will be completed.
All arithmetic, logical operators are operators in c tokens. As: +, - , ++, --, %, &&, &, >>, << etc.
The different types of operators are: Assignment operator- This is used to assign values to variables. Ex: = Arithmetic Operators - These are used to perform arithmetic operations. Ex: +, -, *, /, % Logical Operators - These are used to perform logical checks like: I < 10 or x == Y etc.
arithmatic operator +,-,*,/,% assigment oprator == logical operator &,|,^,&&,,! bitwise opertor &,|,^ left shift << right shift >> left shift zero fill << assignment operator +=,-=,*=,/=
In C programming, the basic operators include: Arithmetic Operators: + (Addition) - (Subtraction) * (Multiplication) / (Division) % (Modulus) Relational Operators: == (Equal to) != (Not equal to) > (Greater than) < (Less than) >= (Greater than or equal to) <= (Less than or equal to) Logical Operators: && (Logical AND) || (Logical OR) ! (Logical NOT) These operators are fundamental for performing operations, comparisons, and logical evaluations in C programs.
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).
ARITHMETIC AND LOGICAL UNIT Anand bhat(mca@kiit-870024)
The unit that performs the arithmetic and logical operations within the processor is called the Arithmetic Logic Unit (ALU).
Arithmetic logic unit
An arithmetic operation combines two numbers while a logical operation uses two logical values which can be true or false. The arithmetic operation uses adding or subtraction to reach the correct answer.
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.

In Verilog, operators can be categorized into several types: Arithmetic Operators: These include addition (+), subtraction (-), multiplication (*), division (/), and modulus (%). Relational Operators: Operators such as equal (==), not equal (!=), greater than (>), and less than (<) compare values. Bitwise Operators: These include AND (&), OR (|), XOR (^), and NOT (~), which operate on individual bits of operands. Logical Operators: Used for logical operations, including logical AND (&&), logical OR (||), and logical NOT (!). Shift Operators: These are used for bit shifting, specifically left shift (<<) and right shift (>>). Each operator serves distinct purposes in digital design and simulation.
The Arithmetic Logic Unit as suggested by the name carries out the arithmetic calculations of the computer.
