  • With your ISP speed, how many books you can download in 1 min? You can assume there are 500,000 characters (500 KByte) in a book of 250 pages, counting the spaces.
    1. BPS means bits per second.
    2. 8 bits is 1 byte.
    3. 10 Mbps means 10 mega bits per second – 10,000,000 bits per second
    4. 10,000,000/8bits = 1,250,000 bytes (characters)
