Bhai woh 4.50 megabyte per second 4.50Mb/sec mein speed baata rehe hai aur aap jo bol rehe hai woh 70 million bits per second hai 70Mbps....................
The abbreviation bps is often used to mean bit/s, so that when a 1 Mbps connection is advertised, it usually means that the maximum achievable bandwidth is 1 Mbit/s (one million bits per second), which is 0.125 MB/s (megabyte per second)
