2. Ethernet crossover cable - Wikipedia

   en.wikipedia.org/wiki/Ethernet_crossover_cable

   An Ethernet crossover cable is a crossover cable for Ethernet used to connect computing devices together directly. It is most often used to connect two devices of the same type, e.g. two computers (via their network interface controllers) or two switches to each other. By contrast, straight through patch cables are used to connect devices of ...

3. Null modem - Wikipedia

   en.wikipedia.org/wiki/Null_modem

   A null modem adapter. Null modem is a communication method to directly connect two DTEs (computer, terminal, printer, etc.) using an RS-232 serial cable.The name stems from the historical use of RS-232 cables to connect two teleprinter devices or two modems in order to communicate with one another; null modem communication refers to using a crossed-over RS-232 cable to connect the teleprinters ...

4. Networking cable - Wikipedia

   en.wikipedia.org/wiki/Networking_cable

   An Ethernet crossover cable is a type of twisted pair Ethernet cable used to connect computing devices together directly that would normally be connected via a network switch, Ethernet hub or router, such as directly connecting two personal computers via their network adapters.

5. Crossover cable - Wikipedia

   en.wikipedia.org/wiki/Crossover_cable

   A null modem cable. A crossover cable connects two devices of the same type, for example DTE -DTE or DCE -DCE, usually connected asymmetrically (DTE-DCE), by a modified cable called a crosslink. [1] Such a distinction between devices was introduced by IBM . The crossing of wires in a cable or in a connector adaptor allows: linking two or more ...

6. Ethernet over twisted pair - Wikipedia

   en.wikipedia.org/wiki/Ethernet_over_twisted_pair

   Ethernet over twisted-pair technologies use twisted-pair cables for the physical layer of an Ethernet computer network. They are a subset of all Ethernet physical layers . Early Ethernet used various grades of coaxial cable, but in 1984, StarLAN showed the potential of simple unshielded twisted pair. This led to the development of 10BASE-T and ...

7. 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 ...
