Understanding bandwidth
The time period bandwidth refers back to the facts rate supported by means of the network connection or the interfaces that connect with the community. It represents both volume and time, representing the amount of facts that may be transmitted between two factors in a fixed time period. Data entering the network is called ingress traffic, and information leaving the network is called egress visitors. Bandwidth is generally expressed in terms of bits consistent with 2nd or, sometimes, in bytes in keeping with 2nd.
Network bandwidth represents the ability of the network connection, even though it's important to understand the difference among theoretical throughput and actual-global consequences when figuring out the right bandwidth system in your community. For example, a 1000BASE-T -- which uses unshielded twisted pair cables -- Gigabit Ethernet (GbE) community can theoretically assist 1,000 Mbps, but this degree can by no means be executed in practice because of hardware and systems software program overhead.
Bandwidth vs. Velocity: 2 special measurements
One point to do not forget whilst considering how to calculate bandwidth wishes in your community is this: Bandwidth ought to not be pressured with throughput, which refers to hurry. While excessive-bandwidth networks are frequently rapid, that is not constantly the case.
A helpful metaphor whilst thinking about bandwidth is motors on a motorway:
A excessive-bandwidth community is like a six-lane toll road that can in shape loads of motors at any given moment.
A low-bandwidth network is sort of a unmarried-lane road in which one automobile drives immediately behind any other.
Although the huge highway is probably to transport automobiles quicker, rush-hour site visitors can without difficulty deliver motors and trucks to a standstill. Or, perhaps, cars can't get onto the motorway quickly because it's clogged with large shipping vehicles that absorb lots of space on the street.
Similarly, even a high-bandwidth community can run slowly in the face of problems, which includes congestion and bandwidth-hungry packages.
