Question

The selector inputs to an arithmetic-logic unit (ALU) determine the:

A. selection of the IC
B. arithmetic or logic function
C. data word selection
D. clock frequency to be used

Answer 1

The selector inputs to an ALU determine the arithmetic or logic function that the ALU will execute, which is essential for various mathematical and logical operations in computer processing.

Step-by-step explanation:

The selector inputs to an arithmetic-logic unit (ALU) determine the arithmetic or logic function that the ALU will perform. This is a crucial aspect, as the ALU is responsible for executing a variety of mathematical and logical operations required in computer processing. Depending on the state of the selector inputs, the ALU can perform operations such as addition, subtraction, multiplication, division, bitwise AND, OR, NOT, XOR, and various shift operations. Therefore, the correct answer is B. arithmetic or logic function.

The selector inputs to an arithmetic-logic unit (ALU) determine the arithmetic or logic function. The ALU is a digital circuit that performs arithmetic and logical operations on binary numbers. The selector inputs, also known as control inputs, control the specific operation to be performed by the ALU, such as addition, subtraction, AND, OR, etc.
