2. RS-232 - Wikipedia

   en.wikipedia.org/wiki/RS-232

   A DB-25 connector as described in the RS-232 standard Data circuit-terminating equipment (DCE) and data terminal equipment (DTE) network. In telecommunications, RS-232 or Recommended Standard 232 [1] is a standard originally introduced in 1960 [2] for serial communication transmission of data.

3. Parallel SCSI - Wikipedia

   en.wikipedia.org/wiki/Parallel_SCSI

   Diagrams of different Parallel SCSI symbols [1]. Parallel SCSI is not a single standard, but a suite of closely related standards. There are a dozen SCSI interface names, most with ambiguous wording (like Fast SCSI, Fast Wide SCSI, Ultra SCSI, and Ultra Wide SCSI); three SCSI standards, each of which has a collection of modular, optional features; several different connector types; and three ...

4. Serial communication - Wikipedia

   en.wikipedia.org/wiki/Serial_communication

   Keyboard and mouse cables and ports are almost invariably serial—such as PS/2 port, Apple Desktop Bus and USB. The cables that carry digital video are also mostly serial—such as coax cable plugged into a HD-SDI port, a webcam plugged into a USB port or FireWire port , Ethernet cable connecting an IP camera to a Power over Ethernet port, FPD ...

5. SCSI connector - Wikipedia

   en.wikipedia.org/wiki/SCSI_connector

   A SCSI connector (/ ˈ s k ʌ z i / SKUZ-ee) is used to connect computer parts that communicate with each other via the SCSI standard. Generally, two connectors, designated male and female, plug together to form a connection which allows two components, such as a computer and a disk drive, to communicate with each other.

6. IEEE 1394 - Wikipedia

   en.wikipedia.org/wiki/IEEE_1394

   IEEE 1394 is an interface standard for a serial bus for high-speed communications and isochronous real-time data transfer. It was developed in the late 1980s and early 1990s by Apple in cooperation with a number of companies, primarily Sony and Panasonic.

7. Modified Modular Jack - Wikipedia

   en.wikipedia.org/wiki/Modified_Modular_Jack

   The Modified Modular Jack (MMJ) is a small form-factor serial port connector developed by Digital Equipment Corporation (DEC). It uses a modified version of the 6P6C modular connector with the latch displaced off-center so standard modular connectors found on Ethernet cables or phone jacks cannot accidentally be plugged in. MMJ connections are used on Digital minicomputers, such as the PDP-11 ...

8. USB hardware - Wikipedia

   en.wikipedia.org/wiki/USB_hardware

   USB 1.0, 1.1, and 2.0 use two wires for power (V BUS and GND) and two wires for one differential signal of serial data. [7] Mini and micro connectors have their GND connections moved from pin #4 to pin #5, while their pin #4 serves as an ID pin for the On-The-Go host/client identification. [8]

9. List of interface bit rates - Wikipedia

   en.wikipedia.org/wiki/List_of_interface_bit_rates

   Contention in a wireless or noisy spectrum, where the physical medium is entirely out of the control of those who specify the protocol, requires measures that also use up throughput. Wireless devices, BPL, and modems may produce a higher line rate or gross bit rate, due to error-correcting codes and other physical layer overhead. It is ...
