Answer:
ALU and CU are the major units in CPU to execute different operations and process information. ALU is used to process arithmetic and logic operations while CU controls the data in/from input, output devices and memory. All the data has been processed in the form of binary data.
Explanation:
As we know that, CPU is the short form of central processing unit. It consist of two major parts Arithmetic and logic unit (ALU) and Control Unit (CU). Both these parts contribute to perform a complete operation in computer. The whole operation has been performed in following sequence using these two components.
The information that need to processed will arrived from some input device or memory location. This information will be interpreted in Machine language that is Binary language.
Control unit is used to control the flow of data and read write operation from/to memory or some I/O device. For Example, If user input data from an input device and want to process and store it in some memory location. The control unit send the signal to read data from input device, process it with the help of ALU and then write it on some memory location.
ALU is Arithmetic and logic unit that perform the operation according to the operators in given instruction that need to be processed. For Example, If user want to add to two inputs and show the result on some output device. Control unit will read the data from input device, interpreter interpret the instruction that what operation need to be performed in machine language. As the addition is an arithmetic operation so, arithmetic unit perform this operation. The result will be again interpreted in high level language and send to write on output device with the help of Control Unit.
