- In asynchronous transmission, the gap time between bytes is _______.With higher bit transmission speed, the duration of each bit in the signal, referred to as the _____, reduces. a. bit time b. overhead c. block time d. modulation time17. An analog signal carries 4 bits in each signal unit. If 1000 signal units are sent per second, then baud rate and bit rate of the signal are ________ and ____________ a. 4000 bauds \ sec & 1000 bps b. 2000 bauds \ sec & 1000 bps c. 1000 bauds \ sec & 500 bps d. 1000 bauds \ sec & 4000 bps
- O Calculate the total number of bits used in downloading a 50 MB video file. Also calculate the time (in minutes) it takes to download the same video file, if the download link is a telephone line with 9600 baud rate. Assume 8 - bits of data per character, 1 – start bit, 1 - stop bit, and 1 parity bit. -Computer Science Suppose that you had more than 4GByte of data to send and could only afford one memory stick but you had plenty of pigeons available (Winston’s extended family). You reason that you can send the data stick back, load it with the next 4GByte of data. What would the throughput of this channel be now?Why does asynchronous transmission have a non-constant delay between bytes?

Calculate the time it takes to transmit a message of size 256 bytes ?In _______ encoding, the duration of the bit is divided into two halves. The voltage remains at one level during the first half and moves to the other level in the second half. The transition at the middle of the bit provides synchronization. a. Manchester b. differential Manchester c. both (a) and (b) d. neither (a) nor (b)
