Originally created by Apple and standardized in 1995 as the specification IEEE 1394 High Performance Serial Bus, FireWire is very similar to USB. The designers of FireWire had several particular goals in mind when they created the standard:
- Fast transfer of data
- Ability to put lots of devices on the bus
- Ease of use
- Hot-pluggable ability
- Provision of power through the cable
- Plug-and-play performance
- Low cabling cost
- Low implementation cost
USB was designed to standardize the connection of computer peripherals, such as keyboards, pointing devices, digital cameras, printers, portable media players, disk drives and network adapters to personal computers, both to communicate and to supply electric power. It has become commonplace on other devices, such as smartphones, PDAs and video game consoles. USB has effectively replaced a variety of earlier interfaces, such as serial and parallel ports, as well as separate power chargers for portable devices.
HDMI (High-Definition Multimedia Interface) is a compact audio/video interface for transferring uncompressed digital audio/video data from an HDMI-compliant device ("the source device") to a compatible digital audio device, computer monitor, video projector, or digital television. HDMI is a digital replacement for existing analog video standards.
