What is the role of the CU and ALU?

ALU and CU are the heart of the CPU. ALU is the Arithmetic and Logic Unit which performs all the arithmetic and logical operations such as addition, subtraction, logical AND, OR etc. CU is the Control Unit. It decodes the instructions, and controls all the other internal components of the CPU to make it work.
A.

What is the definition of Alu?

Abbreviation of arithmetic logic unit, the part of a computer that performs all arithmetic computations, such as addition and multiplication, and all comparison operations. The ALU is one component of the CPU(central processing unit).
  • What is the full form of RAM and ROM?

    The terms "RAM" and "ROM" refer to two types of computer data storage. RAM is an acronym for "random access memory," while ROM stands for "read-only memory." RAM and ROM are alike in certain respects as two forms of memory, so they are easily confused.
  • What is the meaning of RAM in computer?

    RAM (pronounced ramm) is an acronym for random access memory, a type of computer memory that can be accessed randomly; that is, any byte of memory can be accessed without touching the preceding bytes. RAM is found in servers, PCs, tablets, smartphones and other devices, such as printers.
  • What is the definition of Alu?

    Abbreviation of arithmetic logic unit, the part of a computer that performs all arithmetic computations, such as addition and multiplication, and all comparison operations. The ALU is one component of the CPU(central processing unit).
B.

Is the ALU A register?

Registers and the ALU. The arithmetic/logic unit (ALU) of a processor performs integer arithmetic and logical operations. For example, one of its operations is to add two 32-bit integers. The second operand (often in a register).
  • What is Alu biology?

    An Alu element is a short stretch of DNA originally characterized by the action of the Arthrobacter luteus (Alu) restriction endonuclease. Alu elements are the most abundant transposable elements, containing over one million copies dispersed throughout the human genome.
  • What is the machine cycle?

    The steps performed by the computer processor for each machine language instruction received. The machine cycle is a 4 process cycle that includes reading and interpreting the machine language, executing the code and then storing that code.
  • What is a primary and secondary memory?

    Secondary storage (also known as external memory or auxiliary storage), differs from primary storage in that it is not directly accessible by the CPU. The computer usually uses its input/output channels to access secondary storage and transfers the desired data using intermediate area in primary storage.
C.

What are the main function of the control unit?

The control unit (CU) is a component of a computer's central processing unit (CPU) that directs the operation of the processor. It tells the computer's memory, arithmetic/logic unit and input and output devices how to respond to a program's instructions.
  • What is the main purpose of the CPU?

    Central Processing Unit. 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.
  • What is the purpose of the control unit?

    The control unit (CU) is a component of a computer's central processing unit (CPU) that directs the operation of the processor. It tells the computer's memory, arithmetic/logic unit and input and output devices how to respond to a program's instructions.
  • What do you mean by input?

    Input can take a variety of forms, from commands you enter from the keyboard to data from another computer or device. A device that feeds data into a computer, such as a keyboard or mouse, is called an input device. (v.)The act of entering data into a computer.
