Synchronization is performed in the UART protocol based on the timing of the Start bit.1 pointTrueFalse

In UART mode of serial communication,  the data bits of a packet (frame) are usually sent along with the followings:Select one:all of the othersone start bitone or more  stop bitsone parity bit

Which of the following is NOT an advantage of the UART protocol?1 pointFewer wires are needed for communication as compared to a parallel protocolA shared clock is not requiredFewer pins are needed than using a parallel protocolHigher data transfer rates are typically achieved compared to a parallel protocol
