Suppose a file of 10,000 bytes is to be sent over a line at 2400 bps. A. Calculate the overhead in bits and time in using asynchronous communication. Assume one start bit and a stop element of length one bit, and 8 bits to send the byte itself for each character. The 8-bit character consists of all data bits, with no parity bit. B. Calculate the overhead in bits and time using synchronous communication. Assume that the data are sent in frames. Each frame consists of 1000 characters = 8000 bits and an overhead of 48 control bits per frame. C. What would the answers to parts (a) and (b) be for a file of 100,000 characters?

Assume that a system uses 10-bit floating-point representation based on the IEEE floating-point format, in which: . There is 1 sign bit. There are k= 6 exponent bits. The exponent bias is 31. . There are n= 3 fraction bits. ● Convert the decimal number -5.5 into the 10-bit IEEE floating point representation explained above. Write the final result in 10-bit binary format. Show your steps.

For each of the following binary codes, answer all of the following questions with justification: (a) (b) (c) (d) ● ● Is it linear? What is its block length, message length, and rate? What is its distance? How many errors can it detect, and how many can it correct? (To answer this question you should give the largest number of errors that the code can guarantee to detect or correct. For example a simple parity bit can detect 1 or 3 errors but cannot detect 2 errors so we would say this can detect only a single error. No calculations of probability are required.) The code with seven codewords where seven messages are encoded as follows: 0000000 0010011 0100101 0110110 1001001 101 1010 1101100 The code consisting of thirty-two codewords where each codeword consists of a 5-bit message padded with an additional bit to give ODD parity: that is, each codeword contains an odd number of 1s. For example the word 11111 would be padded with a 0 to give 111110, while 00000 would be padded with a 1…

QUESTION 16 Determine the overhead and throughput for the following system. The system uses frames that begin with one start bit and end with 1 stop bit. The frame also contains five 7-bit ASCII characters and each character has one parity bit following it. overhead = 35/40, throughput = 5/40 overhead = 5/40, throughput = 35/40 overhead = 0.8333, throughput = 0.1667 overhead = 0.1667, throughput = 0.8333 overhead = 94.6%, throughput = 5.4% overhead = 5.4%, throughput = 94.6%
