The truth behind Internet Speed

Published On : 16th July, 2018
You might sometime wonder, that why your operator says 5 Mbps of speed you will receive, but you instead receive a max speed of 625 KBps. Right? And you call up your operator and complain about that. But wait, you are actually wrong. They are actually giving you 5 Mbps speed. Have you noticed something? in 5 Mbps its Mbps, the M is capital and b is small, that means its Mega Bits Per Second, and in 625 KBps, both K and B is capital, i.e. Kilo Bytes Per Second.

In internet world, the unit of speed is bps or Bits Per Second but in non internet world, such as file copy or disk speed, its Bps or Bytes Per Second.
 For ex. you are taking a new internet connection of 60 Mbps, and you might think that, "I can download a 60 MB file in just a second :P". Let me explain

1 Mbps = 125 KBps or 0.125 MBps

So, to find out the actual speed you will receive in real world, you have to do a simple calculation

1 Mbps  ÷  8 (Bits) = 0.125 KBps or 0.125 MBps

Where, 8 Bits = 1 Byte, we are dividing 1 Mbps by 8 bits to get it in bytes.

So, for 60 Mbps,
60 Mbps  ÷  8 (Bits) = 7.5 MBps

Here, the 7.5 MBps means you can download a 7.5 MB file in a second. 

Don't get confused, just divide you internet operator's speed by 8 to get the non internet world speed.

For Bps to bps:

Where as, to find out the internet world speed from your download section or real world speed, just multiply it by 8

Ex. - 5 MBps x 8 (Bits) = 40 Mbps

Do you know, in most of the CS job interviews, interviewees fail in this simple question/calculation. 

In the case of disk speed, its always in Bps i.e. Bytes per second, such as MBps, GBps and that won't need any calculation.
