To estimate the total number of bits for a 1-hour lecture script at a delivery rate of 200 words per minute with an average of 5 letters per word, first calculate the total number of words: 200 words/minute multiplied by 60 minutes equals 12,000 words. Next, multiply the total words by the average letters per word: 12,000 words times 5 letters equals 60,000 letters. Since ASCII uses 8 bits per character, the total number of bits is 60,000 letters times 8 bits, resulting in 480,000 bits. Finally, to determine the transmission time at a bitrate of 1 Gb/s, divide the total bits by the bitrate, which yields a transmission time of 0.00048 seconds. This calculation illustrates the efficiency of data transmission for lecture scripts.
