The processor (CPU - Central Processing Unit) consists of two main parts:

Control Unit (CU):

• Directs the flow of instructions and data within the CPU.
• Manages communication between different parts of the computer.

Arithmetic Logic Unit (ALU):

• Performs mathematical calculations (addition, subtraction, etc.).
• Handles logical operations (comparisons like greater than, less than, etc.).

Other Options Explained:

• (A) CPU and Main Memory → Incorrect. Main Memory (RAM) is separate from the processor.
• (B) Hard Disk and Floppy Drive → Incorrect. These are storage devices, not processor components.
• (D) Operating System and Application → Incorrect. These are software, not part of the processor.

Thus, the correct answer is (C) Control Unit and ALU.

Adam Smith is called the "Father of Economics" because he laid the foundation for modern economic thought with his book An Inquiry into the Nature and Causes of the Wealth of Nations, published in 1776. In this book, he introduced key economic concepts such as:

1. The Invisible Hand – The idea that individuals seeking their own self-interest can benefit society as a whole through market competition.
2. Division of Labor – The concept that specialization in production increases efficiency and productivity.
3. Free Market Economy – He advocated for minimal government intervention in economic activities, promoting capitalism and free trade.

His ideas shaped classical economics and continue to influence modern economic policies.
