The technology that enables connectivity of the device, e.g. wired or wireless.

Number of USB 2.0 ports (connecting interfaces) in the device. USB 2.0 was released in April 2000 (now called "Hi-Speed"), adding higher maximum signaling rate of 480 Mbit/s (effective throughput up to 35 MB/s or 280 Mbit/s), USB 2.0 ports are usually black.

Number of VGA (D-Sub) ports (connecting interfaces) in the device. The VGA (D-Sub) connector is a 15 pin connector between a computer and a monitor. It was first introduced in 1987 by IBM.

This is the amount of DVI-I interfaces. Digital Visual Interface (DVI) is a video display interface developed by the Digital Display Working Group (DDWG). The digital interface is used to connect a video source to a display device, such as a computer monitor. DVI-D means DVI digital, which means it can only support digital, but not analog.

The socket where a microphone is connected to the device.

Number of sockets /ports where headphones are connected.

The number of parallel ports. Parallel ports, also known as printer ports, are a type of interface found on computers (personal and otherwise) for connecting peripherals. In computing, a parallel port is a parallel communication physical interface. Parallel ports were common in the 1980s and '90s (mostly conforming to industry standard IEEE 1284) but are now being replaced by USBs and other ports.

The number of serial ports in a computer or peripheral. A serial port is a serial communication physical interface through which information transfers in or out one bit at a time. The term "serial port" usually identifies hardware more or less compliant to the RS-232 standard, intended to interface with a modem or with a similar communication device. In modern computers and peripherals, serial ports have largely been replaced by USBs and other interfaces.

The number of PS/2 connectors for keyboards and mice. Its name comes from the IBM Personal System/2.

The socket/plug where the DC electricity supply connects to the device.

The number of ports (output sockets) for S-Video, which is a signalling standard for standard definition video, typically 480i or 576i.

The socket in the device for the composite video, which is an analog video transmission (no audio) that carries standard definition video typically at 480i or 576i resolution. The cables for composite video are normally yellow.

An Ethernet LAN (Local Area Network) interface is present, for a wired conection via a cable.

Number of Ethernet LAN (RJ-45) ports (connecting interfaces) in the device.  Ethernet LAN (RJ-45) ports allow a computer to connect to the ethernet.

The device includes a card reader e.g. a card reader in the disk bay of a computer or thin client to permit log-on using smart/pin cards.

Holes on the edge of devices through which a cable lock can be passed, so the device can be locked to a desk etc.

The colour e.g. red, blue, green, black, white.
