Question: exercise 13 assume 1 start bit 1 stop bit and...

Question details

Exercise 13 Assume 1 start bit, 1 stop bit, and 8 data bits to send one byte with asynchronous serial communication. Given a baud rate of 19200, determine the the transfer efficiency (data bits/total bits sent)? bytes per second sent. What is Exercise 14 Using the definition of an Ethernet frame give by the Wikipedia article, assume that the frame contains the maximum amount of data, determine how many data bytes per seconds are sent for 10Mbps Ethernet. What is the transfer efficiency (data bits/total bits sent)? The 802.1Q tag should not be included, and the data payload is 1500 octets. What is the data rate if the minimum number of data bytes (46) are sent. What is the transfer efficiency (data bits/total bits sent)? Exercise 15 Determine the even parity bit for the following ASCII characters: A, 0, -. Exercise 16 Determine the bits that are sent for ax3 +1 CRC checksum and the following data bits: 11001001 Be sure the extend the message to 11001001000 by add three 0, before dividing by x3 + 1.
