  2. Registered jack - Wikipedia

    en.wikipedia.org/wiki/Registered_jack

    RJ45 is often incorrectly used when referring to an 8P8C connector used for ANSI/TIA-568 T568A and T568B and Ethernet, however, the plug used for RJ45 is both mechanically and electrically incompatible with any Ethernet port: it cannot fit into an Ethernet port, and it is wired in a way that is incompatible with Ethernet. The connector commonly ...

  3. Wire speed - Wikipedia

    en.wikipedia.org/wiki/Wire_speed

    For example, the wire speed of Fast Ethernet is 100 Mbit/s [1] also known as the peak bitrate, connection speed, useful bit rate, information rate, or digital bandwidth capacity. The wire speed is the data transfer rate that a telecommunications standard provides at a reference point between the physical layer and the data link layer. [2]

  5. Ethernet physical layer - Wikipedia

    en.wikipedia.org/wiki/Ethernet_physical_layer

    The physical-layer specifications of the Ethernet family of computer network standards are published by the Institute of Electrical and Electronics Engineers (IEEE), which defines the electrical or optical properties and the transfer speed of the physical connection between a device and the network or between network devices.

  6. Category 5 cable - Wikipedia

    en.wikipedia.org/wiki/Category_5_cable

    Cross section of a cat 5e cable. The Category 5e specification improves upon the Category 5 specification by further mitigating crosstalk. [9] The bandwidth (100 MHz) and physical construction are the same between the two, [10] and most Cat 5 cables actually happen to meet Cat 5e specifications even though they are not certified as such. [11]

  7. Modular connector - Wikipedia

    en.wikipedia.org/wiki/Modular_connector

    The connector provides power to the keyboard on the outer two contacts and receives data signals on the inner pair. The cable between the computer and the keyboard is a coiled cord with an appearance very similar to a telephone handset cable. [11] The connector on the Amiga 1000 uses crossover wiring, similar to a telephone handset.

  8. Category 6 cable - Wikipedia

    en.wikipedia.org/wiki/Category_6_cable

    Cat 6 cable can be identified by the printing on the side of the cable sheath. [3] Cable types, connector types and cabling topologies are defined by ANSI/TIA-568.. Cat 6 patch cables are normally terminated in 8P8C modular connectors, using either T568A or T568B pin assignments; performance is comparable provided both ends of a cable are terminated identically.

  9. ANSI/TIA-568 - Wikipedia

    en.wikipedia.org/wiki/ANSI/TIA-568

    Perhaps the most comprehensive known and most discussed feature of ANSI/TIA-568 is the definition of the pin-to-pair assignments, or pinout, between the pins in a connector (a plug or a socket) and the wires in a cable. Pinouts are critical because cables do not function if the pinouts at their two ends aren't correctly matched.
