Problem :
a) A good sized English book has about 100000 words. If an average English word is six characters long and each character needs 1 byte, show that the book can be stored in 600 kbyte of memory and show that the text takes nearly 5 seconds to be transmitted at 1 Mbit s-¹. Show that it takes nearly a quarter of an hour to transmit 100 images, each of 1Mbyte on a channel with a transmission rate of 1 Mbit s-¹.
Attempt:
600000 X 8 =4800000 bits - text
600 X 1024 X 8 =4915200 bits - available
1Mbit = 1,000,000 bits = 125000 bytes
600000/125000 = 4.8 seconds
100Mbytes = 100,000,000 bytes / 1,000,000 bytes = 100?
These attempts are total guesses. Can somebody please try and explain the proper solutions.
