Network traffic measurement

Okay, so imagine you're playing with toy cars with your friends. Sometimes there are a lot of cars on the road and sometimes there are only a few. But how do we measure how many cars are on the road at any given time?

In the same way, we can measure the amount of information that's travelling on a computer network - like the internet or a company's internal network. When we measure this, we call it "network traffic measurement".

Just like the cars on the road, the networks can get busy and slow down when a lot of information is being sent at the same time. By measuring the network traffic, we can see how much information is being sent and received, and how fast it's going.

We use special tools called "network traffic analyzers" to do this. They listen in on the traffic and record things like the source and destination of the data, what kind of data it is (like a video or an email), and how much data is being sent.

This information can be used to find out things like which websites or apps are using the most data, which parts of the network are getting congested, and whether there are any security threats.

So, network traffic measurement means measuring how much information is travelling through a computer network, so we can make sure everything runs smoothly and securely. Just like counting toy cars on the road!
