USB, DVI, HDMI Connectors

Universal Serial Bus (USB) is an industry standard that defines the cables, connectors and communications protocols used in a bus for connection, communication, and power supply between computers and electronic devices. The physical connectivity of USB components is provided through the USB connector which is available in two versions, standard and mini, that vary in size respectively. USB connectors are also available in two versions: male (plug) and female (socket) connectors. USB cables are made up of four shielded twisted pairs of wires with different colour codes.

Digital Video Interface (DVI) is a high-bandwidth digital interface commonly used to provide a connection between many digital devices, such as video cards, computers and televisions. It is used to transmit digital video signals, either from an analog device such as a DVD player, or from a digital device such as a laptop computer. DVI connectors come in both single-link and dual-link versions, with the difference being in the type of connector. Single-link DVI connectors come in four types — A, B, D and D-Sub — while dual-link DVI connectors come in three types — A, B and C.

High Definition Multimedia Interface (HDMI) is an industry-supported digital audio/video connectivity standard for transmitting signals between digital devices. HDMI cables transfer both audio and video and are made up of 19 individually shielded wires in a nylon jacket. HDMI connectors have one of two types of ends; standard type A or type B, which feature 19 pins. Different versions of HDMI support different resolutions depending on the cables themselves and the device it\'s connected to.

All three types of connectors — USB, DVI and HDMI — are used to connect different types of digital devices, such as televisions and computers, together in order to send digital signals from one device to another. They are commonly found in electronics devices, such as computers, receivers, DVD players and TVs. While the connectors may look very similar, they are not interchangeable and require different types of cables for different purposes.
