  2. Rollover cable - Wikipedia

    en.wikipedia.org/wiki/Rollover_cable

    A rollover cable (also known as a Yost cable, Cisco cable, or a console cable) is a type of null-modem cable that is used to connect a computer terminal to a router's console port. This cable is typically flat (and has a light blue color) to help distinguish it from other types of network cabling. It gets the name rollover because the pinouts ...

  3. Ethernet crossover cable - Wikipedia

    en.wikipedia.org/wiki/Ethernet_crossover_cable

    A standard straight-through cable is used for this purpose where each pin of the connector on one end is connected to the corresponding pin on the other connector. One terminal may be connected directly to another without the use of a switch or hub, but in that case, the crossover must be done in the cabling. Since 10BASE-T and 100BASE-TX use ...

  4. Serial cable - Wikipedia

    en.wikipedia.org/wiki/Serial_cable

    Serial cables are typically used for RS-232 communication. A serial cable or RS-232 cable is a cable used to transfer information between two devices using a serial communication protocol. The form of connectors depends on the particular serial port used. A cable wired for connecting two DTEs directly is known as a null modem cable.

  5. Crossover cable - Wikipedia

    en.wikipedia.org/wiki/Crossover_cable

    In a straight-through cable, pins on one end correspond exactly to the corresponding pins on the other end (pin 1 to pin 1, pin 2 to pin 2, etc.). Using the same wiring scheme at each end yields a straight-through cable (a given color wire connects to a given number pin, the same at both ends).

  6. Data Carrier Detect - Wikipedia

    en.wikipedia.org/wiki/Data_Carrier_Detect

    Data Carrier Detect (DCD) or Carrier Detect (CD) is a control signal present inside an RS-232 serial communications cable that goes between a computer and another device, such as a modem. This signal is a simple "high/low" status bit that is sent from a data communications equipment (DCE) to a data terminal equipment (DTE), i.e., from the modem ...

  7. Ethernet - Wikipedia

    en.wikipedia.org/wiki/Ethernet

    An Ethernet port on a laptop computer connected to a twisted pair cable with an 8P8C modular connector Symbol used by Apple and Google on some devices to denote an Ethernet connection Ethernet ( / ˈ iː θ ər n ɛ t / EE -thər-net ) is a family of wired computer networking technologies commonly used in local area networks (LAN), metropolitan ...

  8. ANSI/TIA-568 - Wikipedia

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

    A cable terminated according to T568A on one end and T568B on the other is a crossover cable when used with the earlier twisted-pair Ethernet standards that use only two of the pairs because the pairs used happen to be pairs 2 and 3, the same pairs on which T568A and T568B differ. Crossover cables are occasionally needed for 10BASE-T and ...

  9. Network switch - Wikipedia

    en.wikipedia.org/wiki/Network_switch

    A modular network switch with three network modules (a total of 36 Ethernet ports) and one power supply A five-port layer-2 switch without management functionality. Modern commercial switches primarily use Ethernet interfaces. The core function of an Ethernet switch is to provide multiple ports of layer-2 bridging.
