GENERAL HISTOLOGY

Detailed explanation-1: -answer : 1. Microcontroller contains all of the above mentioned three parts. CPU Memory devices I/O ports A microcontroller is a small computer on a single integrated circuit.

Detailed explanation-2: -Modern embedded systems are often based on microcontrollers (i.e. microprocessors with integrated memory and peripheral interfaces), but ordinary microprocessors (using external chips for memory and peripheral interface circuits) are also common, especially in more complex systems.

Detailed explanation-3: -Sensors, ADC, DAC, actuators, FPGA, software, memory, external peripherals are a few of the components of embedded system architecture.

Detailed explanation-4: -Hardware. The hardware of embedded systems is based around microprocessors and microcontrollers. Software and firmware. Software for embedded systems can vary in complexity. Real-time operating system.
