• 2nd Generation: 8086 and 8088 - introduced 16-bit architecture.
• 3rd Generation: 80286, 80386 - 32-bit processors with enhanced capabilities.
• 4th Generation: Pentium series, multi-core processors - increased speed and multitasking abilities.

Microprocessor Architecture

Understanding the architecture is crucial to grasp how microprocessors operate:

• Control Unit (CU): Directs the flow of data and instructions.
• Arithmetic Logic Unit (ALU): Performs mathematical and logical operations.
