A L U - Inside a computer, there is an Arithmetic Logic Unit (ALU), which is capable of performing logical operations (e.g. AND, OR, Ex-OR, Invert etc.) in addition to the arithmetic operations (e.g. Addition, Subtraction etc.). The control unit supplies the data required by the ALU from memory, or from input devices, and directs the ALU to perform a specific operation based on the instruction fetched from the memory. ALU is the “calculator” portion of the computer. C U - 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 the instructions that have been sent to the processor.
The control unit controls and monitors communications between the hardware attached to the computer. The ALU performs simple addition, subtraction, multiplication, division, and logic operations, such as OR and AND. The memory stores the program's instructions and data.
*According to me CU is unit which transacts or transfer and controls data between components of CPU which is done by motherboard . And ALU is actually the processor of computer which does all mathematics such as calculations and computing data.*
Ma'am we 're really awaiting for your video lecture on each unit of Paper 1 covering each subtopic in details just like video lectures on Teaching Aptitude and Research Aptitude. I hope that this guidance for Paper 1 enables your students prepared for UGC NET along with your utmost effort for Paper 2.
Thank u so much ma'am 🥰 was waiting for this video. Your hardwork and dedication will always inspire me 😊 stay safe healthy n happy 😊 take care ma'am 🥰
