Network cables transmit data in bits (0 or 1). Bits represent all the data (pictures, videos or songs)

How fast is your internet speed?

(Check using https://fast.com )

Bandwidth is a number of bits that can be sent per second. There are some examples of bandwidth measurements:

b/s - bits per second (bps)

kb/s - kilobits per second (kbps)

Mb/s - megabits per second (Mbps)

Gb/s - gigabits per second (Gbps)

Mbps: Megabits per second

MBps: Megabytes per second

8 bits = 1 byte

1 Mbps = 1,000,000 bps

1 MBps = 1,000,000 bps = 8,000,000 bps = 8 Mbp

A network cable is like a road and cars on the roads represent data (0 and 1). Data moves in both directions.

Download speed is the speed of data transfer when you receive something from another computer.

Upload speed is the speed of data transfer when you send something to another computer.

How much time do we need to download images, audio or video files?

example of 20 MB data.
Firstly, convert 20 Megabytes into bits:
20 MB = 20 1024 kilobyte = 20 1024 1024 bytes = 20 1024 1024 8 bits = 167 772 160 bits. So, 20 MB = 167 772 160 bits.

Now convert your download speed into bits per second. (Example: 512 Kbps)

512 Kbps = 512 * 1000 bits per second. So, 512 Kbps = 512 000 bps.

Finally, divide file size by download speed (bits per second).

Download time = Data in bits / Download speed in bits.

Download time = 167 772 160 / 512 000 = 327.68 seconds”
