Orders of magnitude refer to how much bigger or smaller one number is compared to another number. It's like comparing the size of a toy car to a real car or the size of a baby to their mother.
When we talk about bit rate, we are talking about how many digital bits (imagine them as tiny pieces of information) can be transmitted per second. For example, if you were downloading a movie from the internet, the bit rate would refer to the speed at which those bits are being sent from the server to your computer.
Now, when we talk about orders of magnitude in bit rate, we are comparing huge differences in speed. This is because the amount of information we can transmit per second varies drastically depending on the technology being used.
For instance, let's say we're talking about your home internet connection. If you have a basic plan, your bit rate might be around 10 megabits per second (Mbps). This means that 10 million bits are being sent to your computer every second. That might seem like a lot, but it's actually very slow compared to other types of connections.
If we increase the bit rate by one order of magnitude, we get 100 Mbps. This is ten times faster than the basic plan! Now we're talking about transmitting 100 million bits per second.
If we increase the bit rate by another order of magnitude, we get 1 gigabit per second (Gbps). This is a thousand times faster than the basic plan! Now we're talking about transmitting 1 billion bits per second.
And if we go even further and increase the bit rate by two orders of magnitude, we get 100 Gbps. This is 10,000 times faster than the basic plan! We're talking about transmitting 100 billion bits per second.
So, orders of magnitude in bit rate simply refer to these huge differences in speed that can happen depending on the technology being used to transmit digital information.
