What is Logic?

Logic is the science of correct thinking. A classic definition is new and necessary reasoning. It's new because you didn't know the item before, and necessary because a correctly formulated syllogism has to be true if the bases are true. This syllogism is a well-known example: All men are m ( Full Answer )

What is the function of Arithmetic Logic unit?

The arithmetic-logic unit (ALU) performs allarithmetic operations (addition, subtraction,multiplication, and division) and logic operations.Logic operations test various conditions encounteredduring processing and allow for different actions to betaken based on the results. The data required to perf ( Full Answer )

What is arithmetic?

Arithmetic is the process of applying the four basic operations:addition, subtraction, multiplication and division to numbers.

What is an arithmetic logic unit?

The arithmetic logic unit, or ALU, is the portion of the CPUresponsible for integer arithmetic. It also handles most logicaloperations.

What is meant by Arithmetic Logic Unit?

Before the developement of micro-processers and micro-computers, a computer was divided into functional units, e.g. reader, punch, bulk memory etc. These were all "peripherals", gathered around and connected to a CPU.. A CPU was a central processing unit, consisting of control, memory, instruction ( Full Answer )

How an ALU differentiate between arithmetic and logic?

It doesn't have to. The ALU is given one or two inputs and is told what operation to perform on them. It has no need to figure out whether that operation is arithmetic or logic, since each individual operation will be different anyway.

What is responsible for performing arithmetic and logical instructions in a computer?

Microprocessor has a component known as ALU(arithmatic and logical unit) whcih is used to perform operations such as . arithmetic includes-add,sub,mul(8086),div(8086) . logical operations include-LOGICAL AND,LOGICAL OR,X-OR . all thsi operations is perofrmed inside the ALU itself with the help of ( Full Answer )

What is the difference between control unit and arithmetic logic unit?

There is a big difference between these components. Both of them are part of central processor unit but control unit is responsible for generating control signals to all parts of cpu, to handle interrupts, to deal with registers etc. Arithmetic logic unit is part which does arithmetic and logic oper ( Full Answer )

What is meant by arithmetic and logical operators?

Arithmetic Operators . Arithmetic operators do exactly what they say, they perform simple arithmetic operations such as addition and subtraction. All arithmetic operators are binary operators, thus they all accept two input values (an lvalue and an rvalue) and output one value, the evaluation of th ( Full Answer )

What is a Arithmetic logical unit?

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.

What part of the CPU performs all arithmetic operations and all logic operations?

CPU expands to Central Processing Unit . CPU as a Unit refers to main components interconnected within a Box called Cabinet. Cabinet houses components such as Power Supply, Motherboard, Processor, RAMs, Harddisk Drive & other components as per requirements. Inside CPU on Motherboard with a ( Full Answer )

What does the arithmetic logic unit alu do?

In computing, an arithmetic logic unit (ALU) is a digital circuit that performs arithmetic and logical operations. The ALU is a fundamental building block of the central processing unit of a computer, and even the simplest microprocessors contain one for purposes such as maintaining timers. The proc ( Full Answer )

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 layer arrange signals into logical units of information called frame?

Layer 2 or the 'Data' layer of the OSI model encapsulates either 'bits' from the physical layer (1)- moving up the TCP stack or 'Packets' from the Network layer (3)- going down the the stack. 7 - Application Layer DATA 6 - Presentation Layer DATA 5 - Session Layer DATA 4 - Transport Layer SEGMENT 3 ( Full Answer )

How Arithmetic Logic Unit is helpful in CPU?

ALU is responsible for the processing of data inside a processor. It analyses and compares numbers, letters and special characters. It performs calculations and does comparisons. It also decoded data and manipulate them to produce information in machine code and then send that to the CU. It analyzes ( Full Answer )

How do you design an Arithmetic Logic Unit?

As the name tells us the alu performs arithmetic and logic operations on two numbers in a CPU. I am answering assuming atleast some knowledge on the functionning of binary logic and computational science. A basic ALU has two input buses for the operators and one input bus for the selection of th ( Full Answer )

How integer represented in arithmetic logic unit?

0 and 1 are the Sign Magnitudes 0 is used as +ve 1 is used as -ve e.g if we see +18 10 = 10010 2 but in the arithmetic representation well be 0 10010 2 -18 10 = 10010 2 but in the arithmetic representation well be 1 10010 2

What is logic unit in CPU?

Logic unit is the portion of CPU which is responsible for all the logical operations performed in the computer

What can logic can do and can not do?

Logic can explain difficult-to-understand concepts to people who are ignorant to pieces of data to support a conclusion. Logic cannot, however, convince someone that something they are stubborn to accept to be true.

Which one is having higher priority arithmetic or logic operator?

In all popular high-level programming languages, the order in which operators are interpreted ("operator precedence") is vital to ensuring that all compilers execute instructions in precisely the same manner, as the "order of operations" rule is vital in mathematics. In the case of C and C++, ari ( Full Answer )

What are the functions of the control unit and arithmetic and logic unit?

Arithmetic and logic units (ALU) performs basic arithmetic operations like addition ,subtraction ,division ,multiplication etc and basic logical operations like OR,AND,XOR,NOT,NAND,NOR etc . Control unit supervises all the functions of different parts of computers by generating control signals .

What is the purpouse Arithmetic and Logic Unit?

That's a chip (or part of a chip) specialized in doing calculations such as additions, subtractions, multiplications, and divisions of floating-point numbers, that is, numbers with decimals (basically, numbers in scientific notation).

Which unit is used in computer for arithmetic calculation?

The bit . One bit contains a binary memory cell that will return a 1 or a zero. In abstract terms, the bit tells the system the answer to ONE UNAMBIGUOUS question with a yes or a no. In Boolean math it is called true or false. In hardware terms, when current flows through the cell, it will either ( Full Answer )

How do the arithmetic shift and logical shift differ?

With a logical shift the vacated bits are always filled withzeroes. With an arithmetic shift, a left shift will fill vacatedbits with zeroes but a right shift fills the vacated bits with acopy of the most significant bit.
