The Full Form of ‘ALU’ in Computer is ‘Arithmetic Logic Unit’.
Full Form of ALU
The full form of ALU in computer is Arithmetic Logic Unit. An ALU, or Arithmetic Logic Unit, is a fundamental component of modern computers. It performs basic arithmetic and logical operations on digital data values.
An ALU is the most important part of any processor chip and is responsible for carrying out the majority of calculations and decisions made by a computer system. It consists of an array of logic gates that perform the various computations needed to calculate a result from a set of input values. The output value can then be used to control additional circuitry or operations within the computer system.
The term “arithmetic” refers to the ability of an ALU to carry out basic arithmetical operations such as addition, subtraction, multiplication and division. These operations are performed on two binary numbers that are stored in separate registers within the ALU. The registers contain a number in binary form, which corresponds to its decimal representation when interpreted by the processor. When an operation is requested, these two numbers are read from their respective registers and processed according to the instructions given by the instruction register within the ALU.
The term “logic” refers to the ability of an ALU to evaluate logical statements such as comparisons between two values (greater than/less than/equal etc.). This allows it to make decisions based on these comparisons as well as performing other types of logical functions such as shifting bits between registers or performing bitwise operations like AND/OR/NOT etc.
In addition to its primary role in performing arithmetic and logic operations, an ALU can also be used for controlling other components within a computer system such as memory management units or input/output devices. By sending commands through its control bus it can direct these components how they should respond when certain events occur or when specific data conditions have been met.
Today’s modern processors contain multiple Arithmetic Logic Units (ALUs) that work together simultaneously in order to process instructions quickly and efficiently allowing us to enjoy faster computation speeds than ever before imaginable. Without it we wouldn’t have access to many applications that rely heavily on computing power such as video editing software, 3D rendering programs and more sophisticated artificial intelligence systems like those used in self-driving cars today!
Overall, ALUs are fundamental components of any modern computing system today thanks largely due their ability not just perform basic arithmetic and logic functions but also control other components within a computer system enabling them operate effectively together with minimal user input or oversight required!
