Silly doubt (networks, speed)

[torquis]

Hello everyone:

Well, you see, I'm a bit confused about internet speeds, transfer rates, bandwidth, MB, Mbps, etc.

To simplify, when an ISP offers 100 MB, I'm not sure if it's MEGABITS, MEGABYTES, MEGABITS/SECOND or MEGABYTES/SECOND.
What does this figure of 100 MB refer to? That is, is it a connection speed, etc. etc. What do you call it?

Well, once you tell me what this is, the company tells me that 100 MB arrive at my house, okay, but after reading a bit I see that everything will depend on the equipment, that is (router + network adapter), that is, each one has its standards, for example (Ethernet, Ethernet 10 Gb, 802.11n) that show the maximum speed at which I can transmit data. Knowing this, that is, the standard of my router and network card, when a company offers me 100 Mbps, I can know what standard it will use, what devices will it use?

diagram:

company (100 Mbps) –---> house (router 802.11g) ---> network card (802.11n) --> pc (speed??)

I think I've confused you a bit, don't I?
The thing is that it's so poorly explained for the common user what speed is, and how it influences, and what arrives and how to improve the devices according to their standard, etc. etc. I'm not clear...

And by the way, my speed according to Windows in the local area network center is 1 Gbps. WHAT DOES THIS MEAN, THAT I HAVE SUBSCRIBED... well, I subscribed for 50 Mbps, because the speed is 1 Gbps?

Best regards.

The "speed" is expressed in megabits per second, but it is actually about capacity :sisi:

Imagine that connections are pipes, and the more capacity you have, the thicker they are, but that doesn't mean you're always using them at maximum.

If you contract 100Mb (Mbps) with your internet provider (ISP), you can expect to download at ~10 Megabytes per second, but it will totally depend on the capacity of the place from which they are sending you the information.

You also have to take into account that some connections provided by ISPs are based on technologies that do not allow them to offer the speeds they advertise commercially, so it may be the case that you contract a 20Mb (Mbps) ADSL but because of the distance or the quality of the cable that reaches your house, you don't get even 4 Mb <:(. This doesn't happen with fiber, if you pay for 20Mb you will have 20Mbps.

Finally, the fact that Windows tells you that your connection is 1Gbps is because it indicates the maximum capacity of your network card.

Salu2!

PD: the 802.11(letter) are WiFi transmission capacities

So well explained to understand. Thanks Fassou.
