Ethernet cable colors refer to two different things: the standardized colors of internal twisted-pair conductors and the non-universal colors of outer cable jackets. Blue, yellow, red, green, black, and other jacket colors may help identify cables, but they do not independently define cable category, speed, shielding, PoE capability, or application.

The RJ45 color code follows two standard termination schemes: T568A and T568B. T568B uses White/Orange, Orange, White/Green, Blue, White/Blue, Green, White/Brown, and Brown from pins 1 to 8. T568A swaps the orange and green pairs.

Choosing the right printer cable starts with identifying the correct connection not just finding a plug that fits. Printers may use USB, Ethernet, parallel, serial, or other interfaces depending on the device and application.

A shielded cable helps reduce the impact of electromagnetic interference (EMI) and radio frequency interference (RFI) on signal, power, and communication lines. However, adding a shield does not automatically eliminate interference.

HDMI terminology is often confusing because HDMI cable type, HDMI connector type, and HDMI port type are not the same thing. Standard, Mini, and Micro HDMI mainly describe the physical connector form factor, while actual cable performance also depends on the HDMI cable category, certification, construction, length, and the capabilities of the connected devices.

A MIDI cable carries digital control and performance data, not the actual audio signal. In a traditional MIDI connection, the cable transmits instructions that tell another device what to do musically, rather than carrying the sound itself.

A computer cable is a cable assembly used to transmit data, video, audio, network signals, electrical power, or a combination of these functions between computers, peripherals, displays, network equipment, storage devices, and internal PC components.

A coaxial cable connector is the interface that terminates a coax cable and transfers the signal into the mating connector while preserving the cable’s conductive and shielding paths.

An AV cable is a broad term for cables used to carry audio and/or video signals, but in many consumer applications, “AV cable” specifically refers to the familiar red, white, and yellow composite RCA cable.
