- The arithmetic logic unit (ALU) is responsible for all logical and mathematical operations in the system. The ALU receives instructions from the control unit. The ALU can take information from memory, perform computations and comparisons, and then store the results in memory locations as directed by the control unit.

Central processing unit Bottom side of an Intel 80486DX2, showing its pins. A central processing unit (CPU) is the electronic circuitry within a computer that carries out the instructions of a computer program by performing the basic arithmetic, logical, control and input/output (I/O) operations specified by the instructions. The computer industry has used the term central processing unit at least since the early 1960s.

Orbitals, the Basics: Atomic Orbital Tutorial â probability, shapes, energy; Crash Chemistry Academy An atomic orbital is a mathematical function that describes the wave-like behavior of either one electron or a pair of electrons in an atom. This function can be used to calculate the probability of finding any electron of an atom in any specific region around the atom's nucleus.

Instruction unit From Wikipedia, the free encyclopedia. The instruction unit (IU) in a central processing unit (CPU) is responsible for organising program instructions to be fetched from memory, and executed, in an appropriate order. It is a part of the control unit, which in turn is part of the CPU. In the simplest style of computer architecture, the instruction cycle is very rigid, and runs exactly as specified by the programmer.

Atomic Transactions Atomic Transactions. Atomic transactions guarantee that any partial updates are rolled back automatically in the event of a failure during the transactional update, and that the effects of the transaction are erased (except for the effects of any .NET calls that are made in the transaction). Atomic transactions in BizTalk orchestrations are similar to distributed transaction coordinator (DTC) transactions in that they are generally short-lived and have the four ACID attributes (atomicity, consistency ...

- The CPU (Central Processing Unit) is the part of a computer system that is commonly referred to as the brains of a computer. The CPU is also known as the processor or microprocessor. The CPU is responsible for executing a sequence of stored instructions called a program [program: a list of instructions written in a programming language ]. This program will take inputs [input: Everything that goes into a system. The three most common inputs in industry are physical inputs, labour and capital.

assembler An assembler is a program that takes basic computer instruction s and converts them into a pattern of bit s that the computer's processor can use to perform its basic operations.Some people call these instructions assembler language and others use the term assembly language. This sequence of assembler instructions, known as the source code or source program, is then specified to the assembler program when that program is started.

Machine code Every program directly executed by a CPU is made up of a series of such instructions. Numerical machine code (i.e., not assembly code) may be regarded as the lowest-level representation of a compiled or assembled computer program or as a primitive and hardware-dependent programming language.

Arithmetic Logic Unit (ALU): Definition, Design & Function 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. In addition to ALUs, modern CPUs contain a control unit (CU).he control unit tells the ALU what operation to perform on that data and the ALU stores the result in an output register. The control unit moves the data between these registers, the ALU, and memory.

Arithmetic Logic Unit (ALU) Definition - What does Arithmetic Logic Unit (ALU) mean? An arithmetic logic unit (ALU) is a major component of the central processing unit of a computer system. It does all processes related to arithmetic and logic operations that need to be done on instruction words. In some microprocessor architectures, the ALU is divided into the arithmetic unit (AU) and the logic unit (LU).
