Scenario 1 : 1 9 , 5 0 0 ASCII characters are transmitted over a 3 Mbps circuit. The protocol uses 8 - bits to
Scenario : ASCII characters are transmitted over a Mbps circuit. The protocol uses bits to encode each ASCII character, and adds an additional parity bit to help detect errors.
Calculate the transmission efficiency of this protocol.
Determine the effective data rate of sending these characters over the circuit using the abovedefined protocol.
Scenario : A person types a plaintext email consisting of characters into their email client, and the characters are encoded with bit Unicode. When the person hits the Send button, the email client uses the SMTP protocol to transmit the message, with an SMTP header of bytes. SMTP is running over TCP over IP over Ethernet, and the Ethernet link is running at Gbps
Calculate the size of the email message in bytes.
Calculate the transmission efficiency of sending this email, using the nominal overhead sizes for the TCP and IP protocols, and the standard Ethernet II overhead size.
Determine the effective data rate of sending this email.
