What is Bandwidth?

To understand bandwidth and latency we need clear meaning of both, so we should begin with data transmission. Transmission capacity is the measure of information that can be exchanged starting with one point then onto the next regularly estimated right away. Web suppliers typically publicize their Internet transmission capacity like this 20/20 Mbps which implies that 20 megabits/s of information can be transferred or downloaded from YouTube in a second. A lot of people are just comfortable with transmission capacity estimating terms like Megabytes, Gigabytes, and so forth. Yet Internet suppliers still utilize the Megabit metric since it makes the numbers look greater however in actuality a 20/20 Mbps association is just around 2 megabytes. The essential thing to recall about data transmission is that transfer speed isn’t speed.

What is Latency?

Latency is the time that an information bundle takes to travel from one point to the next. Another exact term for Latency is delay. One essential thing to recall about Latency is that it is a characteristic marvel hypothesized by Einstein in the hypothesis of relativity. In our universe, everything needs time to movement, even light. So on the Internet, the time it takes a bundle to movement (from Facebook’s server to your PC for example) it’s called Latency.

What’s the difference between bandwidth and latency?

By perusing the meaning of the two terms above you likely as of now recognize the difference between the two, yet I’ll give you a relationship to make it less difficult to understand it on the off chance that you are as yet confused. Imagine a road way with 4 paths where as far as possible is 60 mph. Now on the Internet, bandwidth is the highway, and latency is the 60 mph speed limit. Now if you want to increase the amount of cars that travels through the highway you can add more lanes, but because the highway has too many curves, and bumps, you can’t increase the speed limit so all cars have to travel at 60 mph still. It doesn’t matter how many lanes the highway has, the cars will get to their destination at the same time regardless of the size of the highway.

Why increasing bandwidth increases download speed then you may ask, isn’t that speed? No, by expanding transfer speed you increment limit not speed. Following the highway analogy, imagine that vehicles traveling through that highway were all trucks with house bricks for delivery. All trucks have to travel at 60 mph, but once they arrive at their destination instead of delivering 4 loads of bricks, 6 loads are delivered because 2 more lanes were added to the highway. The same thing happens when you add bandwidth to an Internet connection, the capacity is increased but the latency (speed) stays the same.

What causes dormancy?

Inertness is caused by the separation and the nature of the medium that the Internet parcels travel through. For instance, the inertness through a fiber optic association is shorter than through a copper wire link, yet idleness through a copper wire link is shorter than through a satellite association, and so forth. Satellites utilize the microwave range to transfer information associations from space. What builds the inertness e.g. slack in satellite associations is the separation that bundles need to movement forward and backward.

At the point when is inertness an issue?

A lot of people don’t see and care less about latency in so far as site pages, Netflix, YouTube, and other sight and sound stuff stack quickly. Latency turns into an issue just when constant information exchange is essential. For example, VOIP calls, online face to face meetings, and so on. I have learned that any unresponsiveness past 200ms will give you issues continuously communication for example in a Skype or VOIP call, you will encounter a visible delay, which will make it relatively difficult to have a fluid discussion without interferences.

How can I test latency?

The fastest method to test latency from any PC is utilizing the ICMP convention with the Ping direction. For instance, on the off chance that I need to test the latency between my PC and Google’s server farm, I will type in the order ping google.com:

As you can see the normal inertness between my PC and Google’s server farm is 255ms.
