Question
(a) For the bit stream 010011, show the waveforms for each of the code indicated. Consider that the signal level for NRZ-L for mark is positive; the signal level for the previous bit (NRZI) was a mark and was positive; the most recent preceding mark (AMI) was negative and the most recent preceding space was positive.
(b) Using the generator polynomial x4 + x + 1 and the message: 010001111100.
Determine the codeword which is transmitted using CRC.
(c) Show the waveform for an asynchronous transmission assuming the following:
8 data bits with value 11010001 (LSB listed first here), one parity bit (even), one start bit, one stop bit, and a baud rate of 100.
Transmission starts at time t = 0, label the starting/ending time for each bit in the transmission. Initially, idle line is high.
a. PKI and PGP are two methods for generating and managing public keys for use in protocols such as secure email. Compare and contrast the trust models for public keys used in PKI

Gateways They transfer packets among network machines that have different protocols (e.g. between a WAN and a LAN). They access a packet formatted for one protocol and change
TRANSMISSION ERRORS: Transmission exceptions may happen due to different causes for example power surges or interference may delete data during transmission. In result of wh
