The Universal Serial Bus standard has been extremely successful. USB ports and cables connect hardware such as printers, scanners, keyboards, mice, flash drives, external hard drives, laptops, etc.

USB was developed in 1990 in an effort to simplify the connections between computers and other devices. It has become popular due to its compatibility with many platforms and operating systems. USB has a low-cost implementation and it is easy to use.

There are various types of USB Connector:

  • USB – A
  • USB – B
  • USB – C
  • USB Micro-A
  • USB Micro-B
  • USB Mini-B (5-Pin)
  • USB Mini-B (4-Pin)
  • USB 3.0 A
  • USB 3.0 B
  • USB 3.0 Micro B
  • USB Micro – AB
  • USB Mini- B (Fuji)

FireWire: FireWire is an I/O interface developed by Apple Computer. It is also known as IEEE (Institute of Electrical and Electronics Engineers) 1394, which is the technical name standardized by the IEEE.

FireWire is a high-speed real-time interface for serial bus and isochronous/synchronous data transfer between enabled devices. FireWire is a high-speed data transfer interface that was used to connect personal computers, audio and video devices, and other professional and consumer electronics.

FireWire bus can connect up to 63 devices. Windows Operating System(98 and later) and MAC OS (8.6 and later) both. FireWire was developed by Apple in the 1990s. It came with some extraordinary features that the other connectors doesn’t provide at that time.
