Toggle through application activity, bandwidth usage, NetFlow sources, and other tabs to pinpoint exactly where the bottleneck is occurring. Light is actually made up of particles called photons, and they do not move in a straight line through the cabling. The technology, if it ever exists, could also be used for going slower than light, but much faster than we can go now, which might be more practical. Speed Equals Quality The speed of your connection determines the quality of the video you watch and the audio you listen to. The speed of light in vacuum is 2.998 10 8 m/s, which is approximately equal to 1 ft/ns. "Richard Feynman on the Weirdness of Physical Reality." Throughput tells you how much data was transferred from a source at any given time and bandwidth tells you how much data could theoretically be transferred from a source at any given time. The standard measure of your internet speed is Megabits per second abbreviated as Mbps. Throughput and bandwidth can be used to measure an applications speedand administrators need this information to make improvements to their networks. Megabits are the speed data travels within your connection, where magabytes refers to the size of a file. Abyte is equal to 8 bits, and a thousand bytes is a kilobyte. So, what are throughput and bandwidth? Even if a computer is on a connection with high bandwidth, its speed of sending and receiving messages will still be limited by the latency of the connection. Technically Speaking. You can also configure random samplings of flow data packets to reduce the load on the monitored system and collector. Each time the packet goes through a network node (i.e a router or a switch, like a crossing) the number is decreased. Sept. 29, 2011. Even if youre not an administrator and looking at this from a productivity standpoint, its also helpful to know what apps are gumming up the works. The overall speed of a computer or " clock speed " of a computer is usually determined by how fast it processes data. The idea is that space time could be contracted in front of a spaceship and expanded behind it, while the ship would remain stationary in a warp bubble that itself was moving faster than the speed of light. In an electrical connection (such as Ethernet), the signal would be a voltage or current. Bandwidth refers to the size of the pipe in which data travels.
