UART stands for Universal Asynchronous Receiver Transmitter.

UART (Universal asynchronous receiver / transmitter) is responsible for performing the main task in serial communications with computers. This device changes incoming parallel information to serial data which can be sent to communication line. UART is capable of encapsulating a byte that might be 5, 6, 7 or 8 bits wide in start and stop bits. Moreover it can attach an extra parity bit with the data for error detection. The width of stop bits may also vary. UART performs all the tasks, timing, parity checking, etc. needed for the communication.

Two different between Mac address and ip address

* MAC addresses are used at layer 2 of the OSI model; IP addresses are layer-3 addresses.* MAC addresses are globally unique. IP addresses may not be unique, if private addresses are used.

* IP addresses have a sort of hierarchical structure (at the very least, network and host parts). MAC addresses are "flat" (no hierarchy).

* MAC addresses are 6 bytes long. IP addresses are either 4 or 16 bytes long.

* A MAC address is only relevant within its network. An IP network may be globally relevant.
