Cross section of a cat 5e cable. The Category 5e specification improves upon the Category 5 specification by further mitigating crosstalk. [9] The bandwidth (100 MHz) and physical construction are the same between the two, [10] and most Cat 5 cables actually happen to meet Cat 5e specifications even though they are not certified as such.

The first IBM PC power supply unit (PSU) supplied two main voltages: +5 V and +12 V. It supplied two other voltages, −5 V and −12 V, but with limited amounts of power. Most microchips of the time operated on 5 V power. Of the 63.5 W these PSUs could deliver, most of it was on this +5 V rail.
USB was designed to standardize the connection of peripherals to personal computers, both to exchange data and to supply electric power. It has largely replaced interfaces such as serial ports and parallel ports and has become commonplace on various devices.
Parallel ATA (PATA), originally AT Attachment, also known as Integrated Drive Electronics (IDE), is a standard interface designed for IBM PC-compatible computers.It was first developed by Western Digital and Compaq in 1986 for compatible hard drives and CD or DVD drives.
Power-line communication (PLC) is the carrying of data on a conductor that is also used simultaneously for AC electric power transmission or electric power distribution to consumers. The line that does so is known as a power-line carrier .
Specifications taken from the packaging of a 610 W PC power supply showing active PFC rating. Active PFC is the use of power electronics to change the waveform of current drawn by a load to improve the power factor. [25] Some types of the active PFC are buck, boost, buck-boost and synchronous condenser. Active power factor correction can be ...
Serial cables are typically used for RS-232 communication.. A serial cable or RS-232 cable is a cable used to transfer information between two devices using a serial communication protocol.
