Microprocessor:
A microprocessor is an integrated circuit that contains the functions of a central processing unit (CPU) of a computer. It is designed to execute a series of instructions stored in memory to perform arithmetic, logical, control, and input/output operations. Microprocessors are primarily used in general-purpose computers, servers, and other computing devices.

Microcontroller:
A microcontroller is also an integrated circuit, but it combines the functions of a microprocessor with peripheral devices such as memory, input/output ports, timers, and serial communication interfaces on a single chip. Microcontrollers are designed to perform specific tasks and are commonly used in embedded systems, automation, control systems, and consumer electronics.

Differences between Microprocessor and Microcontroller:

Architecture:
- Microprocessors have a Von Neumann architecture, where data and instructions share the same memory space.
- Microcontrollers have a Harvard architecture, where data and instructions are stored in separate memory spaces.

Functionality:
- Microprocessors are designed to provide general-purpose computing capabilities and execute complex software applications.
- Microcontrollers are designed to perform specific tasks and control external devices with minimal external components.

Memory:
- Microprocessors rely on external memory devices like RAM and ROM for program and data storage.
- Microcontrollers have built-in memory, including RAM, ROM, and flash memory, which eliminates the need for external memory devices.

Power Consumption:
- Microprocessors typically consume more power due to their complex architecture and higher clock speeds.
- Microcontrollers are designed to operate at lower clock speeds and have low power consumption, making them suitable for battery-powered devices.

Cost:
- Microprocessors are generally more expensive as they require additional components such as memory, input/output devices, and support chips.
- Microcontrollers are cost-effective as they integrate most essential components on a single chip, reducing the overall system cost.

Applications:
- Microprocessors are commonly used in desktop computers, laptops, servers, and high-end computing devices.
- Microcontrollers are widely used in embedded systems, robotics, home automation, automotive systems, medical devices, and consumer electronics.

In conclusion, microprocessors and microcontrollers differ in terms of their architecture, functionality, memory, power consumption, cost, and applications. While microprocessors are designed for general-purpose computing, microcontrollers are specialized for specific tasks and offer a more integrated solution with built-in memory and peripheral devices.
