[SIZE=2]I am having trouble answering this assignment question.. i was wondering if anybody could give me a hand

[/SIZE]

[SIZE=2]Ulysses the user types an e-mail message, includes a JPEG image as an attachment, and uses private-key encryption to send it from his computer (on a LAN) to Ursula (another user, on a different computer, on a different LAN).[/SIZE]

[FONT=Arial][SIZE=2]Explain in detail the path of the message from the moment Ulysses clicks on the “send” button until the message is received in full in a decrypted form on Ursula’s machine. Assume that Ulysses and Ursula are physically separated by 4000 kilometres, necessitating use of the Internet. Include in your explanation a description of all communication protocols used in the transmission, and the functions of all the hardware involved.[/SIZE][/FONT] [FONT=Arial][SIZE=2]You should include what happens to the data as it is prepared for transfer on Ulysses’ computer, passed through the Internet, and processed by Ursula’s computer. You should include the Application, Network and Transport protocols used, what they are designed to achieve, and how they achieve this (details of handshake messages are not needed), and any other processes that need to occur to ensure that the message is delivered correctly. You should also describe and explain the functions of the hardware components that handle the message.[/SIZE][/FONT][SIZE=2]


Thanks[/SIZE]
