Some providers also provide unmetered bandwidth by giving a capped port like 100Mbps.
If you don't use much bandwidth and would like the ability to burst to say 1gbps then a metered plan is better.
If you think you may use most/all bandwidth then consider u metered
Metered/Unmetered is usually a term to describe to bandwidth limitations. When you have metered package you either have your bandwidth totally limited or partially (limits port speed after you reach a certain amount of bandwidth). Also, when you have an unmetered bandwidth that means your bandwidth is unlimited and there should not be any limitations.
The difference is in the terms actually. It is obvious what metered means and it is very much the same with unmetered. When it comes to Internet bandwidth "Unmetered" refers to the maximum capacity of the logical (or physical) port in use for any service. So, if someone offers "1 Gbps Unmetered" this is supposed to mean that the use should be able to utilize up to 1000 Mbps (1 Gbps) of internet bandwidth.
Bandwidth is the amount of data that can be transferred in a specific amount of time. For example, if you have 100Mbps bandwidth, you can transfer up to 100Mb of data within a second. Bandwidth is a measurement of speed. Data transfer is the actual amount of data used.
Metered bandwidth means you have a limited amount of bandwidth that you pay for. Charges will apply when you exceed the set amount.
Unmetered bandwidth means there is no limitation to how much you can use, while sharing the same port with others.
