Major components on a PICMG 1.3 active backplane Wire-wrapped backplane from a 1960s PDP-8 minicomputer. A backplane or backplane system is a group of electrical connectors in parallel with each other, so that each pin of each connector is linked to the same relative pin of all the other connectors, forming a computer bus.
Examples of computer connector sockets on various laptops Ports on the back of the Apple Mac Mini (2005) A computer port is a hardware piece on a computer where an electrical connector can be plugged to link the device to external devices, such as another computer, a peripheral device or network equipment. [1] This is a non-standard term.
Enhanced Small Disk Interface (ESDI) was an attempt to minimize controller design time by supporting multiple data rates with a standard data encoding scheme; this was usually negotiated automatically by the disk drive and controller; most of the time, however, 15 or 20 megabit ESDI disk drives were not downward compatible (i.e. a 15 or 20 ...
Dell Precision T3600 System Motherboard, used in professional CAD Workstations. Manufactured in 2012. A motherboard (also called mainboard, main circuit board, MB, mobo, base board, system board, or, in Apple computers, logic board) is the main printed circuit board (PCB) in general-purpose computers and other expandable systems.
Removal of the front panel itself may or may not require the removal of one or both of the side panels. If there is any doubt, consult the user's manual if possible. Traditionally, most computer cases required computer case screws to hold components and panels in place (i.e. motherboard, PSU, drives, and expansion cards). From the early 2000s ...
An IEEE 1284 36-pin female on a circuit board. In the 1970s, Centronics developed the now-familiar printer parallel port that soon became a de facto standard.Centronics had introduced the first successful low-cost seven-wire print head [citation needed], which used a series of solenoids to pull the individual metal pins to strike a ribbon and the paper.
Perhaps the most end-user visible and lasting impact of PC 99 was that it introduced a color code for the various standard types of plugs and connectors used on PCs. [3] As many of the connectors look very similar, particularly to a novice PC user, this made it far easier for people to connect peripherals to the correct ports on a PC.
The front panel data port (FPDP) is a bus that provides high speed data transfer between two or more VMEbus boards at up to 160 Mbit/s with low latency. The FPDP bus uses a 32-bit parallel synchronous bus wired with an 80-conductor ribbon cable. [1] The following interface functions are supported: [2]
