What is the role of the ALU in data processing?
The brain of any computer is its CPU. However, the brain of any CPU is the ALU. ALU short for Arithmetic And Logical Unit is the component that resides inside the CPU which processes data according to the given instructions && commands.
Why computer made for?
A computer is a device that can be programmed to carry out a set of math or logical operations automatically.
Block diagram of a computer with explanation?
A computer can process data, pictures, sound and graphics. They can solve highly complicated problems quickly and accurately. A computer as shown in Fig. performs basically five major computer operations or functions irrespective of their size and make. These are1) it accepts data or instructions by way of input,2) it stores data,3) it can process data as required by the user,4) it gives results in the form of output, and5) it controls all operations inside a computer.We discuss below each of these Computer operations1. Input: This is the process of entering data and programs in to the computer system. You should know that computer is an electronic machine like any other machine which takes as inputs raw data and performs some processing giving out processed data. Therefore, the input unit takes data from us to the computer in an organized manner for processing.2. Storage: The process of saving data and instructions permanently is known as storage. Data has to be fed into the system before the actual processing starts. It is because the processing speed of Central Processing Unit (CPU) is so fast that the data has to be provided to CPU with the same speed. Therefore the data is first stored in the storage unit for faster access and processing. This storage unit or the primary storage of the computer system is designed to do the above functionality. It provides space for storing data and instructions.The storage unit performs the following major functions:• All data and instructions are stored here before and after processing.• Intermediate results of processing are also stored here.3. Processing: The task of performing operations like arithmetic and logical operations is called processing. The Central Processing Unit (CPU) takes data and instructions from the storage unit and makes all sorts of calculations based on the instructions given and the type of data provided. It is then sent back to the storage unit.4. Output: This is the process of producing results from the data for getting useful information. Similarly the output produced by the computer after processing must also be kept somewhere inside the computer before being given to you in human readable form. Again the output is also stored inside the computer for further processing.5. Control: The manner how instructions are executed and the above operations are performed. Controlling of all operations like input, processing and output are performed by control unit. It takes care of step by step processing of all operations inside the computer.FUNCTIONAL UNITSIn order to carry out the operations mentioned in the previous section the computer allocates the task between its various functional units. The computer system is divided into three separate units for its operation. They are1) arithmetic logical unit2) control unit.3) central processing unit.Arithmetic Logical Unit (ALU) Logical UnitLogical Unit :After you enter data through the input device it is stored in the primary storage unit. The actual processing of the data and instruction are performed by Arithmetic Logical Unit. The major operations performed by the ALU are addition, subtraction, multiplication, division, logic and comparison. Data is transferred to ALU from storage unit when required. After processing the output is returned back to storage unit for further processing or getting stored.Control Unit (CU)The next component of computer is the Control Unit, which acts like the supervisor seeing that things are done in proper fashion. Control Unit is responsible for co ordinating various operations using time signal. The control unit determines the sequence in which computer programs and instructions are executed. Things like processing of programs stored in the main memory, interpretation of the instructions and issuing of signals for other units of the computer to execute them. It also acts as a switch board operator when several users access the computer simultaneously. Thereby it coordinates the activities of computer's peripheral equipment as they perform the input and output.Central Processing Unit (CPU)The ALU and the CU of a computer system are jointly known as the central processing unit. You may call CPU as the brain of any computer system. It is just like brain that takes all major decisions, makes all sorts of calculations and directs different parts of the computer functions by activating and controlling the operations.

What are the two primary sections located on the CPU?
the units of the CPU are :- ALU (arithmetic and logical unit) CU(control unit) the ALU handles the arthmetic operations being done by the application and the CU is responsible for handling the instruction passed by the micro processor.
What are the functions of arithmetic logic unit?
The Arithmetic Logic Unit as suggested by the name carries out the arithmetic calculations of the computer.
What are the main components of CPU of a computer system?
The central processing unit (CPU) is the brain of your computer. 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 operations specified by the instructions. Following are the prime components of CPU: - The arithmetic logic unit (ALU), which performs arithmetic and logical operations. - The control unit (CU), which extracts instructions from memory and decodes and executes them, calling on the ALU when necessary.
Bits and bytes are used as the language that tells the computer what to do?
To so arithmetic and logical operations
What are the 3 units in a computer?
