(1) In dot-matrix printers, the devices that press on the ink ribbon to make dots on the paper. Printers are classified by how many pins they have on the printer head. The more pins a printer has, the higher-quality type it is capable of producing. Dot-matrix printers can have anywhere from 9 to 24 pins. A 24-pin printer can produce letter-quality print.
(2) A male lead on a connector.
(3) Silicon chips have an array of thin metal feet (pins) on their underside that enables them to be attached to a circuit board. The pins are very delicate and easily bent. If they are damaged, the chip will not sit correctly and will malfunction.
- pincushion distortion
A common type of distortion in CRT monitors in which horizontal and vertical lines bend inwards toward the center of the display. The distortion is most noticeable at the edges of the display. The opposite of pincushion distortion is barrel distortion, in which horizontal and vertical lines bend outwards toward the edge of the display. […]
- ping of death
(ping &v deth) (n.) A type of DoS attack in which the attacker sends a ping request that is larger than 65,536 bytes, which is the maximum size that IP allows. While a ping larger than 65,536 bytes is too large to fit in one packet that can be transmitted, TCP/IP allows a packet to […]
- ping triangulation
A process developed by IBM in which client requests over the Internet can be routed to the cell that is geographically closest. When one or more mirror sites exists, ping triangulation uses a process called echo location. When a server receives a client request, it sends out an ICMP echo, or ping, packet across the […]
A diagram or table that describes the purpose of each pin in a chip or connector, or each wire in a cable.
- pinned item list
The list of programs on the Start menu in the Microsoft Windows OS is divided into two parts: the programs displayed above the separator line (also known as the pinned items list) and the programs displayed below the separator line (also known as the most frequently used programs list). The programs on the pinned items […]
