MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -There are 2 parts of the CPU: The ALU and Control Unit. The Arithmetic Logic Unit (ALU) performs arithmetic operations (such as addition and subtraction) and logical operations (such as comparing two values). The Control Unit deciphers and carries out instructions.

Detailed explanation-2: -In some processors, the ALU is divided into two units: an arithmetic unit (AU) and a logic unit (LU). Some processors contain more than one AU–for example, one for fixed-point operations and another for floating-point operations.

Detailed explanation-3: -Central Process Unit It consists of an arithmetic and logic unit (ALU), a control unit, and various registers. The CPU is often simply referred to as the processor. The ALU performs arithmetic operations, logic operations, and related operations, according to the program instructions.

Detailed explanation-4: -ALU and CU is that arithmetic logic unit, another component of the processor, performs arithmetic, comparison, and other operations. While control unit is the component of the processor that directs and coordinates most of the operations in the computer.
