👉 FireWire, or more specifically FireWire 400 (FW400), is a high-speed serial digital communication technology developed by Peripheral Component Interconnect (PCI) Technology, Inc. It uses twisted-pair copper wiring to transmit data at speeds up to 400 Mbps, making it suitable for connecting high-bandwidth devices like external hard drives, USB flash drives, and network-attached storage (NAS) systems. The fluid in FireWire refers to the physical medium, typically a twisted-pair cable, which carries the electrical signals necessary for data transmission. The design of FireWire cables is optimized to minimize interference and ensure reliable, high-speed communication, making them a preferred choice for connecting modern peripherals to computers.
