There is one main difference between combinational ALU and sequential ALU. Combinational ALU depends only on present circuits, and sequential ALU depends on both the present and the past.

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.


What is the difference between multiprocessing using two ALUs and multitasking using one ALU?

ALU stands for arithmetic and logic unit. The ALU does complex calculations, so by having two it gets the job done faster. This may not really make a difference if your an average user, although if you do AutoCAD and stuff that requires rendering then it will make a HUGE difference.


Can ALU do square roots?

No - computing a square root with any degree of accuracy is both a numerical and iterative process. Because of this, it can not be calculated with a combinatorial circuit like an ALU. It requires a sequential circuit, so you at the very least need some memory paired with the ALU to compute a square root. If you are interested in the numerical methods for calculating square roots, go see the wikipedia page on the topic (check the link).


Which unit of computer performs arithmetic and logical functions?

The ALU (arithmetic logic unit) An ALU loads data from input registres, an external Control Unit then tells the ALU what operation to perform on that data, and then the ALU stores its result into an output register. Other mechanisms move data between these registers and memory.

Differentiate between CU and ALU?

The ALU (Arithmetic-Logic Unit) is generally a subsection of the CPU (Central Processing Unit). While the CPU is the master driver of a computer, the ALU is a processing area optimized to handle mathematical computations and logic comparisons. The processor controller passes operation codes and operands to the ALU, which performs the requested operation on the supplied data and passes back the results.
