1. The binary representation of the word "UNITAR" is "010101010100111001001001 0101010001000001 D1010010". This representation shows each letter as an 8-bit binary number. With the Longitudinal Redundancy Check (LRC) algorithm and odd-parity, what would be the redundant bit stream that will be added to the original data? 11101010000101011010110001010011 4. In order to code 8-bit long data of 11010101, how many hamming codes are needed and what are their values from left to right? 4,10114,10013,1013,100 5. What is the corresponding bit stream to this signal, assuming Manchester encoding was used for encoding? 6. Based on the ENQ/ACK line discipline. If the sender node has not received an ACK or NAK from the receiver node after WT units of time have passed, what will it do? Data will be resent by the sender. Communication will be terminated by the sender. Data will be assumed to have been received by the sender. 7. In POLL/SELECT line discipline, what is the purpose of the SEL frame? Primary intends to send data to secondary. The SEL frames are used by the primary to send some selected data to the secondary. The SEL frames are used by the secondary to send data to the primary. Data will be sent by the secondary to the primary
