$1.$ Briefly explain the difference between Serial and Parallel communication. $(2)2.$ Serial communication uses two methods. Name and give a description of each. $(2)3.$ When configuring an AVR for asynchronous serial communication, what is typically the first step? $(1)4.$ What is the function of the RXC flag in the UCSRA register? $(1)5.$ Assuming we are transmitting the ASCII letter $\text{'}$e$\text{'},$ with no parity bit and one stop bit, show the sequence of bits transferred. The LSB is sent first. $(2)6.$ What is the purpose of the UDRIE bit in the UCSRB register? $(1)7.$ In AVR serial communication, which register is used to hold the data to be transmitted or received? $(1)8.$ Which register is used to set the baud rate in AVR microcontrollers? $(2)9.$ Name two communication protocols used in Serial Communication. $(2)10.$ For a crystal frequency of $16$MHz$,$ what value should be loaded into
