What is the mechanism inside a computer that actually does the arithmetic and logical operations
What are arithmetic and logical operations in computers?
An ALU performs basic arithmetic and logic operations. Examples of arithmetic operations are addition, subtraction, multiplication, and division. Examples of logic operations are comparisons of values such as NOT, AND, and OR. … Operations can be accomplished by connecting multiple transistors.
Which part of the computer does arithmetic operations?
ALU
An arithmetic unit, or ALU, enables computers to perform mathematical operations on binary numbers. They can be found at the heart of every digital computer and are one of the most important parts of a CPU (Central Processing Unit).
What in computers are capable of performing arithmetic and logical operations?
An arithmetic logic unit (ALU) is a digital circuit used to perform arithmetic and logic operations. It represents the fundamental building block of the central processing unit (CPU) of a computer. Modern CPUs contain very powerful and complex ALUs.

How does the control unit work?
A control unit or CU is circuitry that directs operations within a computer’s processor. … A control unit works by receiving input information that it converts into control signals, which are then sent to the central processor. The computer’s processor then tells the attached hardware what operations to carry out.
How does the ALU affect the performance of a microprocessor?
Using its ALU (Arithmetic/Logic Unit), a microprocessor can perform mathematical operations like addition, subtraction, multiplication and division. … A microprocessor can move data from one memory location to another.

…
Control unit
- it fetches , decodes and executes instructions.
- it issues control signals that control hardware.
- it moves data around the system.
What functions are performed by the control unit can we call it the control Centre of computer system Why?
Answer: The Control Unit (CU) controls and guides the interpretation, flow and manipulation of all data and information. The CU sends control signals until the required operations are done properly by ALU and memory.
How does a 1 bit adder work?
A 1-bit adder circuit accepts two 1-bit binary numbers and a carry input and outputs a 1-bit sum and a carry. … The logic circuitry for a 1-bit adder is shown in the following figure. These are the instructions to play with the circuit: Click on the 1’s and 0’s in green (the inputs) to change their value.
How many arithmetic and logic operations are possible in a 4 bit ALU?
16 logical operations
The 4-bit wide ALU can perform all the traditional add / subtract / decrement operations with or without carry, as well as AND / NAND, OR / NOR, XOR, and shift. Many variations of these basic functions are available, for a total of 16 arithmetic and 16 logical operations on two four-bit words.
What is NAND logic gate?
In digital electronics, a NAND gate (NOT-AND) is a logic gate which produces an output which is false only if all its inputs are true; thus its output is complement to that of an AND gate. A LOW (0) output results only if all the inputs to the gate are HIGH (1); if any input is LOW (0), a HIGH (1) output results.
What is Binary Adder explain?
Binary Adders are arithmetic circuits in the form of half-adders and full-addersb used to add. together two binary digits. Another common and very useful combinational logic circuit which can be constructed using just a few basic logic gates allowing it to add together two or more binary numbers is the Binary Adder.
How does a ripple carry adder work?
Ripple Carry Adder works in different stages. Each full adder takes the carry-in as input and produces carry-out and sum bit as output. The carry-out produced by a full adder serves as carry-in for its adjacent most significant full adder. When carry-in becomes available to the full adder, it activates the full adder.
What is bubbled AND gate?
Bubbled AND gate: The AND gate with inverted inputs is called as Bubbled AND gate which is also called as negative AND gate. NOR gate is also called as an active low AND gate since its output becomes high only when all its inputs are equal to 0.
What is latch circuit?
In electronics, a flip-flop or latch is a circuit that has two stable states and can be used to store state information – a bistable multivibrator. … Flip-flops and latches are fundamental building blocks of digital electronics systems used in computers, communications, and many other types of systems.
