The correct answer is A. Arithmetic logical unit.
An ALU (arithmetic logic unit) is a digital circuit that performs arithmetic and logical operations on numbers. It is a fundamental building block of many computers and other digital devices.
The ALU is typically made up of a number of logic gates, which are simple circuits that perform basic operations such as AND, OR, and NOT. The ALU can also include more complex circuits, such as adders, subtractors, and multipliers.
The ALU is typically connected to the CPU (central processing unit) and the memory. The CPU sends instructions to the ALU, which then performs the necessary operations on the data that is stored in memory.
The ALU is a very important part of any computer. It is responsible for performing all of the basic arithmetic and logical operations that are necessary for the computer to function.
Here is a brief explanation of each option:
- Option A: Arithmetic logical unit. This is the correct answer. The ALU is a digital circuit that performs arithmetic and logical operations on numbers.
- Option B: Array Logical Unit. This is not the correct answer. The ALU is not an array.
- Option C: Application logic unit. This is not the correct answer. The ALU is not an application logic unit.
- Option D: Application logic universal. This is not the correct answer. The ALU is not an application logic universal.
