How an embedded system communicate with the outside world?

A	Peripherals
B	Memory
C	Input
D	Output

Explanation:

Detailed explanation-1: -Communication devices are used to connect the embedded system to the outside world. The communication devices include Ethernet, Wi-Fi, Bluetooth, and other wireless and wired communication technologies. The communication devices are used to transfer data between the embedded system and other systems.

Detailed explanation-2: -Peripheral Devices in Embedded Systems Universal Serial Bus (USB) Multi Media Cards (SD Cards, Compact Flash, etc.) Networks like Ethernet, LonWorks, etc. Fieldbuses like CAN-Bus, LIN-Bus, PROFIBUS, etc.

Detailed explanation-3: -Embedded systems use the communication ports to transmit data between the processor and peripheral devices–often, other embedded systems–using a communication protocol. The processor interprets this data with the help of minimal software stored on the memory.

Detailed explanation-4: -The four communication protocols most commonly used and essential for any embedded engineer to know include UART, SPI, I2C and USB.
