Standardised as IEEE 802.3, it connects computers, network-attached storage (NAS) or network-ready printers to the network and it is the most widespread wired LAN (Local Area Network) technology.
The Universal Serial Bus (USB) is a standard for peripheral devices. It allows it to be easier to connect a number of external devices to PCs and simplify the software configuration of all devices connected to USB, as well as allowing greater bandwidths for external devices.
The IEEE 1394 interface is a serial bus interface standard for high-speed communications and isochronous real-time data transfer, often used by personal computers, as well as in digital video and audio, automotive and aeronautics applications. It is also known as i.LINK (Sony) and Lynx (Texas Instruments).
A fibre optic can carry up to 10 million messages at any time using light pulses. Widely used in fibre-optic communications, it allows transmission over longer distances and at higher bandwidths than other forms of communications. Unaffected by electromagnetic interference and no cross-talk between signals and no pickup of environmental noise.
SATA & eSATA
Serial ATA (Serial Advanced Technology Attachment) is a bus interface for computers to connect adapters such as mass storage devices (hard disk drives and optical drives).
Low-voltage differential signalling, uses twisted-pair copper inexpensive cables that can run at very high speeds, often used in networks and computer buses.
