CPU socket

A CPU socket or CPU slot is a mechanical component that provides mechanical and electrical connections between a microprocessor and a printed circuit board (PCB). This allows the CPU to be replaced without soldering.
Common sockets have retention clips that apply a constant force, which must be overcome when a device is inserted. For chips with a large number of pins, either zero-insertion force (ZIF) sockets or land grid array (LGA) sockets are used instead. These designs apply a compression force once either a handle (for ZIF type) or a surface plate (LGA type) is put into place. This provides superior mechanical retention while avoiding the risk of bending pins when inserting the chip into the socket.

PCI Express x16

PCI Express ("Peripheral Component Interconnect Express", abbreviated: PCIe or PCI-E) is an extension standard for connecting peripheral devices to the chipset of a main processor. PCIe is the successor of PCI, PCI-X and AGP and offers a higher data transfer rate per pin compared to its predecessors.
During its development the interface was called "3GIO", which stands for "3rd Generation Input/Output".

HDMI type A receptacle

The High-Definition Multimedia Interface (HDMI) is a compact audio/video connector interface for transmitting uncompressed digital streams. It represents a digital alternative to consumer analog standards such as Radio Frequency (RF) coaxial cable, composite video, S-Video, SCART, component video, D-Terminal, and VGA.
