Does The ALU manages all activities inside the processor?

Answer 1

ALU is primarily responsible for arithmetic and logical calculations and is not responsible for all the activities inside the processor. e.g. many processors have inbuilt memory controllers which interface with memory or bus drivers, bus arbiters all of which will be performing autonomous functions and will be interfacing with various sub modules through data or control signals. ------- A processor contains three basic components; an input/output unit, a control unit, and ALU's. The control unit manages all activities inside the processor itself. -----

Answer 2

No, the ALU does arithmetic or logic on bytes of data. The ALU is part of the CPU.

CPU architectures vary widely, but basically the clock runs a state machine, and the wiring or control store (computer within the computer) causes bytes to be moved around, to and from RAM, CPU registers and sometimes through the ALU. The result is that instructions are fetched and executed, which is all that computers do.

Answer 3

Managing the activities inside the processor is the function of the CU (control unit). The ALU performs all arithmetic and logic functions of the processor.
