  2. List of interface bit rates - Wikipedia

    The physical phenomena on which the device relies (such as spinning platters in a hard drive) will also impose limits; for instance, no spinning platter shipping in 2009 saturates SATA revision 2.0 (3 Gbit/s), so moving from this 3 Gbit/s interface to USB 3.0 at 4.8 Gbit/s for one spinning drive will result in no increase in realized transfer rate.

  3. IEEE 802.3 - Wikipedia

    en.wikipedia.org/wiki/IEEE_802.3

    IEEE 802.3 is a working group and a collection of standards defining the physical layer and data link layer's media access control (MAC) of wired Ethernet. The standards are produced by the working group of Institute of Electrical and Electronics Engineers (IEEE).

  4. Data-rate units - Wikipedia

    en.wikipedia.org/wiki/Data-rate_units

    The ISQ symbols for the bit and byte are bit and B, respectively.In the context of data-rate units, one byte consists of 8 bits, and is synonymous with the unit octet.The abbreviation bps is often used to mean bit/s, so that when a 1 Mbps connection is advertised, it usually means that the maximum achievable bandwidth is 1 Mbit/s (one million bits per second), which is 0.125 MB/s (megabyte per ...

  5. Measuring network throughput - Wikipedia

    en.wikipedia.org/wiki/Measuring_network_throughput

    The Max TCP Window size in the absence of TCP window scale option is 65,535 bytes. Example: Max Bandwidth = 65,535 bytes / 0.220 s = 297886.36 B/s * 8 = 2.383 Mbit/s. Over a single TCP connection between those endpoints, the tested bandwidth will be restricted to 2.376 Mbit/s even if the contracted bandwidth is greater.

  6. Media-independent interface - Wikipedia

    en.wikipedia.org/wiki/Media-independent_interface

    For gigabit operation, the GTXCLK is supplied to the PHY and the TXD, TXEN, TXER signals are synchronized to this. For 10 or 100 Mbit/s operation, the TXCLK is supplied by the PHY and is used for synchronizing those signals. This operates at either 25 MHz for 100 Mbit/s or 2.5 MHz for 10 Mbit/s connections. In contrast, the receiver uses a ...

  7. MAC address - Wikipedia

    en.wikipedia.org/wiki/MAC_address

    The Individual Address Block (IAB) is an inactive registry which has been replaced by the MA-S (MAC address block, small), previously named OUI-36, and has no overlaps in addresses with the IAB [6] registry product as of January 1, 2014. The IAB uses an OUI from the MA-L (MAC address block, large) registry, previously called the OUI registry.

  8. Memory bandwidth - Wikipedia

    en.wikipedia.org/wiki/Memory_bandwidth

    Memory bandwidth is the rate at which data can be read from or stored into a semiconductor memory by a processor. Memory bandwidth is usually expressed in units of bytes/second, though this can vary for systems with natural data sizes that are not a multiple of the commonly used 8-bit bytes. Memory bandwidth that is advertised for a given ...

  9. Network throughput - Wikipedia

    en.wikipedia.org/wiki/Network_throughput

    The bandwidth of wired systems can be in fact surprisingly narrow, with the bandwidth of Ethernet wire limited to approximately 1 GHz, and PCB traces limited by a similar amount. Digital systems refer to the 'knee frequency', [ 7 ] the amount of time for the digital voltage to rise from 10% of a nominal digital '0' to a nominal digital '1' or ...
